from the editor

First-World Problem

Cory Sekine-Pettite, editor To make comments or suggestions, send e-mail to cory@lionhrtpub.com.

Recently, I renovated one of the bathrooms in my home. I tore it down to the studs and started from scratch. The process wasn’t easy or swift, but it wasn’t the work that was the difficult part – it was the decision-making. My wife and I spent months determining what materials, fixtures, furniture, and paint colors we wanted to incorporate. We weren’t arguing over tile and faucets – in fact, we generally have the same taste in home décor. What took so long was actually wading through web pages, sifting through materials samples, and working with our wise contractor to create our ideal bathroom.

As you know, home renovations often can seem like herculean chores. Why is it easier to help make design choices for clients (or even friends), but borderline impossible to decide for yourself what tile and fixtures to install in your own residence? Have you experienced this with your own home improvement projects?

Anyway, as I’m sure you can attest, just as soon as the new bathroom started coming together – my “renovation brain” still in high gear – I started thinking of other potential home improvements to tackle. Why do we

torture ourselves like this? Why was I already thinking of new ways to stress myself before I could even take a shower in the new bathroom? Was I nesting? Are men actually capable of nesting?

Truthfully, I just want to make a few improvements to my home before moving into a larger space. So now a new fireplace surround and mantle sit atop my renovation list. In this case, the choices are perhaps even more overwhelming. For materials, I can choose among brick, stone veneer, river rock, tile, and so on.

Beyond that, I also need to settle on a color scheme. Do I go for a traditional design, or take a more modern approach? And lest I forget, what can I actually afford?

You might be thinking: “Cory, this is where professional designers come in.” And you would be right. The folks who helped us with our bathroom – the same people who helped us redesign our kitchen several years ago – have been invaluable. I have total respect for their broad knowledge, and by extension, the expertise of the larger design/build community.

Struggling over materials selection for a home improvement project is a total first-world problem, but I sure am glad to have a wealth of professional assistance just a phone call or email away. wMD

IMI Presents the Masonry Education Webinar Series Now through May, a Masonry Education Webinar Series is available, sponsored by the International Masonry Institute. These webinars are intended for designers, facility managers, construction managers, owners, and members in good standing of the International Union of Bricklayers and Allied Craftworkers, and their signatory contractors.

The programs began in January; the remaining courses are as follows: http://www.imiweb.org/

Tuesday, February 3 Noon to 1:30 p.m. Eastern Designing and Detailing Quality Masonry Structures

This presentation will focus on all aspects of the complete masonry cavity wall system including veneer, the cavity, flashing and weeps, insulation and concrete masonry units. The program will show how all these parts work together to provide an energy-efficient wall system that will be durable as well as cost-efficient.

Tuesday, February 17 Noon to 1:30 p.m. Eastern Advanced Masonry Details for Buildings & Landscape Architecture

This presentation will highlight new advances in masonry, rainscreen, and landscape design.

Tuesday, March 3 – Noon to 1:30 p.m. Eastern Current Methods and Methodology for Cleaning Historic Masonry Structures

This session presents the rationale and methodology for cleaning both interior and exterior historic masonry surfaces. Cleaning can be the first type of repair measure performed on a new masonry structure to remove any construction residue.

Cleaning can also be performed as part of a maintenance program or restoration project. In each of

these instances, the masonry can be susceptible to damage caused by an improper selection of materials or methods. Understanding how to approach and develop a proper testing program is the first step in determining which technique will clean the building while promoting long-term performance.

The program will introduce current cleaning systems and describe their general performance and applications. Specific attention will be paid to chemical, micro-abrasive, laser and latex systems.

Tuesday, March 24 Noon to 1:30 p.m. Eastern Sustainability and Resiliency for Existing Masonry Buildings

Significant prospects exist for restoring and retrofitting the exterior and interior systems in existing masonry buildings. This seminar will examine strategies for addressing resilient design in existing buildings that include energy savings passive systems, durable design, occupant comfort, and indoor air quality that will improve building flexibility. This seminar also will examine and cross reference LEED concepts related to LEED for Existing Buildings: Operations & Maintenance.

Tuesday, April 7 Noon to 1:30 p.m. Eastern Do’s and Don’ts of Tornado Shelter Design

This presentation will focus on correct planning for storm shelters based on the applicable ICC and FEMA standards. Tornado impact, shelter design and examples, owner and design professional perspectives, and project funding are discussed.

Bruss Landscaping Wins 2014 Hardscape North America Best-Project Award Wheaton, Ill.-based landscape firm recognized nationally for home renovation project that epitomizes a popular trend in outdoor living.

Bruss Landscaping, a suburban Chicago landscape contractor, is the winner of a 2014 HNA Hardscape Project Award for a recently completed project that highlights a popular trend in home design and outdoor living – the front patio.

The annual HNA Hardscape Project awards recognize outstanding hardscape projects across North America by contractors building residential and commercial walkways, patios, driveways and commercial plazas, parking lots, streets and more.

The concept of a front patio continues to be the trend in residential neighborhoods where owners of modern-era homes, missing the big front porches of yesteryear, want to reconnect with their community in a casual, spontaneous way. The front patio functions as a fresh-air foyer or sitting area where homeowners can greet neighbors or passers-by, or simply enjoy the beauty of their own front yards.

The award-winning project designed and built by Bruss Landscaping topped the field of competitors as best-in-category for Residential Clay Brick for its superb craftsmanship and detail with materials. w w w.masonr ydesignmaga zine.com

Located in suburban Chicago, the project is a craftsman-style home on a semi-wooded lot with good frontage views. The design and installation team at Bruss worked with the homeowners on the redesign of the front entry, driveway, and green spaces to transform an obscured entryway into a more sociable front patio.

Bruss removed the standard asphalt driveway and replaced it with a horseshoe-shape drive constructed of “Old Chicago” clay brick pavers, complete with a radiant heat system under the brick for melting snow. The former plain, 3-foot-wide concrete walk was replaced with an elegant brick walk and spacious bluestone sitting area. Four stone columns around the sitting area support a custom wood pergola where flowering vines climb overhead. A custom stone fountain harmonizes with the craftsman architecture and provides the pleasing sound of water. wMD Winter 2014-15

ASLA to Renovate its Headquarters into Center for Landscape Architecture The American Society of Landscape Architects (ASLA) has embarked on a $4-million plan to renovate its headquarters building to create a Center for Landscape Architecture.

The organization purchased the 12,000-squarefoot building in 1997 for $2.4 million, just as D.C.’s Chinatown neighborhood was being revitalized.

After 17 years of occupancy, any building would be in need of renovation. However, ASLA leaders saw the opportunity to do much more.

“Today, our headquarters is in a vibrant neighborhood, and the building is valued at $6.9 million – a 189-percent return on our investment,” said Mark A. Focht, FASLA, immediate past president of the ASLA, in presenting the renovation plan to the Society’s Board of Trustees for approval in late November 2014. “This is an opportunity to create a facility to reflect the image and ethic of our profession – a world-class Center for Landscape Architecture that will inspire and engage our staff, our membership, allied professionals, public officials, and the general public.”

The ASLA Board of Trustees approved the $4-million plan with nearly unanimous support.

“ASLA paid off the original mortgage last summer, so the Society is in an excellent financial position to take out a $3-million mortgage and raise the balance of what we need through fundraising and product donations,” said Nancy C. Somerville, Hon. ASLA, executive vice president/CEO of the Society.

Focht made a personal pledge to contribute $15,000 to the project and challenged the other Board members to join him in launching the fundraising efforts. James Burnett, FASLA, founder of award-winning landscape architecture firm The Office of James Burnett, donated $25,000 to the project and volunteered to chair a fundraising task force to raise the remaining funds needed.

“Since the Board approved the project on November 20, we’ve received more than $330,000 in payments and pledges – that’s over 33 percent of our goal,” said Burnett. “We’ll also seek in-kind product donations lighting, furniture, green walls, kitchen appliances, surfacing, and other items.

We’re committed to creating a space for ASLA’s national headquarters that reflects the complexity and vitality of our profession, and the more successful our fundraising is, the more successful the project will be.”

LEED:

A FOCUS ON PRODUCT TRANSPARENCY 12 |

Materials • Technolog y • Trends

WHEN USGBC LAUNCHED LEED V4, it significantly advanced its mission to “transform the way we think about how buildings and communities are designed, constructed, maintained, and operated.” It was, perhaps, the most significant shift in program approaches since LEED was started 14 years ago, with changes designed to push designers and builders into new realms of sustainability innovation.

Some of the most dramatic changes came in the Materials & Resources (MR) section, where product transparency and life cycle assessment (LCA) are given considerable emphasis – encouraging, if not forcing, a more holistic view of product specification.

In previous versions of LEED, the MR section included credits for single attributes such as recycled content or regional materials (sourcing products from within 500 miles of the jobsite). That initial approach was suitable for the program in its w w w.masonr ydesignmaga zine.com

GREEN BUILDING

[ABOVE]

Under LEED v4, architects can earn credits for specifying products that have a third-party-verified environmental product declaration, such as that available from CalStar.

early years, when the idea of green certification and specifying green materials were new concepts.

The earlier versions of LEED also wound up driving change at the manufacturing level and led to more sustainable products. “For the place where the market was 10 years ago, that was an effective way to define what a green product was,” says Sarah Buffaloe, LEED materials specialist at USGBC. “As a result of these credits, we saw an uptick in information available and in new products. For example, we saw an incredible supply chain transparency start to appear as a result of the awareness of regionality as a sustainability factor.”

But most stakeholders agree that, while that initial approach had value, it also had limitations. Most notably, it essentially allowed people to pick some attributes, while ignoring others. For example, a product that incorporated a large quantity of recycled material could earn credits, even if that product also had a high carbon footprint.

With experience, as well as a much wider selection of green products, it is now easier to build a green building than it was a decade ago. USGBC recognized that they could encourage people to look for ways to get even greener, and challenged the program committee to look at the MR credits more holistically. The result is LEED v4, released in 2013, in which the MR section promotes product transparency by awarding credits for using products with LCAs and that reduce environmental impact in multiple ways instead of just one.

How it works Under LEED v4 Materials & Resources, users can earn several credits.

Product Disclosure and Optimization

There are credits available for using products that state what materials are used (product disclosure). There are also credits for products whereby manufacturers reduce the environmental impact (product optimization).

IN THE NEWS

BSD Supports Green Initiatives Building Systems Design Inc. (BSD), a company offering software tools for the architecture, architectural engineering and construction markets, has published revisions to 116 specification sections related to sustainable design for architects and engineers.

BSD SpecLink-E, BSD’s automated specification production system, has supported the various LEED rating systems published by the U.S. Green Building Council (USGBC) for many years. BSD’s latest sustainability updates support LEED v4 BD+C, USGBC’s most recent green rating system. The updates support other green initiatives, such as the Green Globes project developed by the nonprofit Green Building Initiative.

BSD accomplishes this support of multiple green systems by organizing all relevant design issues into five categories: 14 |

Masonr yDesign

|

Winter 2014-15

• Location – Requirements intrinsic to location, such as access to transit or use of a brownfield site • Design Phase – Topics related to activities during project design, such as site master planning • Post-Construction – Occupancy issues, such as green power offsets and “no smoking” policies • Design Embodiment – Performance issues such as daylighting, views and energy usage • Contract Documents – Requirements explicitly included on drawings and/ or in specifications, such as site boundaries for vegetation protection and contractor’s quality procedures.

Materials • Technolog y • Trends

There are several ways to get these credits: tt

Environmental Product Declarations Option 1. Use products with some sort of Environmental Product Declaration (EPD).

• Product-specific declaration.

• These are products with publicly available, critically reviewed LCAs conforming to ISO 14044. Products with externally verified LCAs are considered more transparent than those with internally verified LCAs. • Or Environmental Product Declaration • This is a document based on the results of the LCA published by the manufacturer. It shows the environmental impact of the product in a variety of categories (e.g., fossil fuel depletion, global warming potential, etc.). This document can be weaker or stronger depending on the rigor of its third-party review.

• Or USGBC-approved program that creates some sort of EPD or other sustainable product certification.

WITH EXPERIENCE, AS WELL AS A MUCH WIDER SELECTION OF GREEN PRODUCTS, IT IS NOW EASIER TO BUILD A GREEN BUILDING THAN IT WAS A DECADE AGO.

And/or Option 2. Multi-Attribute Optimization

• Use third-party products with documented reduction in environmental impact in at least three categories, compared to industry average. Note that this option requires some sort of industry average information to be available, which is not always the case.

Categories include global warming potential (greenhouse gases), depletion of the stratospheric ozone layer, acidification of land and water sources, eutrophication, formation of tropospheric ozone, and depletion of nonrenewable energy resources (fossil fuel use).

• Or products must comply USGBC approved multi-attribute frameworks.

In addition, extra credit is given for products sourced within 100 miles of the project site. This is one way in which the regional materials attribute is retained with LEED v4.

In general, BSD places the sustainable design requirements in each applicable specification section, rather than gathered together in a single section, so the issues can be addressed independently of which rating system is being used on a particular project.

BSD SpecLink-E is built on a relational database, rather than word processing files, so BSD has built into the database more than 170,000 “intelligent links” that help to edit project specifications based on decisions made by the user. This linking feature is especially helpful when a design professional wishes to pursue certification under a particular green rating system.

By activating Section 01 3329 – Sustainable Design Reporting, a user can select the desired rating system, and make further choices from the w w w.masonr ydesignmaga zine.com

options presented. The built-in links will automatically activate related provisions in other spec sections. When all necessary specification sections have been fully edited, the system can print a submittals report that lists all sections in the project requiring submittal of sustainable design documentation.

Subscribers to BSD SpecLink-E can automatically download and install the hundreds of paragraphs involved in this sustainability update through a new software feature. Instead of quarterly updates that replace the entire master database, BSD’s system lets users choose to have updates downloaded as frequently as daily, but not less often than quarterly.

Or, the user can download and apply all available updates to the master database within a few minutes.

GREEN BUILDING Sourcing of Raw Materials The idea here is to reward stakeholders for using products verified to have been sourced responsibly.

Option 1. Raw Material Source and Extraction Reporting

• Manufacturers use raw materials suppliers who source materials responsibly and have clear, ecologically responsible land use practices, as well as a commitment to reduce environmental damage that could result from material extraction.

And/or Option 2. Leadership Extraction Practices

• The user specifies a certain amount of products that meet requirements for “extended producer responsibility” or “leadership extraction” criteria. Functionally, all wood specified is FSC-certified.

The recycled materials and materials reuse attributes in previous versions of LEED are embedded in this credit. Extra credit is also given for products sourced within 100 miles of the project site.

Material ingredients The idea behind this credit is to ensure that manufacturers reduce use and generation of harmful ingredients.

Option 1. Report all ingredients that make up at least 0.1% of product. Manufacturers can keep intellectual property or proprietary chemicals secret as long as they disclose what the chemicals do and if they are harmful.

And/or Option 2. Use no harmful substances. Substances of concern are listed in a comprehensive database (or on multiple lists). Any ingredients used in quantities greater than 100 ppm are considered.

And/or Option 3. Use products from manufacturers whose supply chain has already been third-party verified to manage health, safety and environmental characteristics of chemical ingredients. Alternatively, source products from manufacturers with robust safety, health, hazard and risk programs that document at least 99 percent by weight of all ingredients that go into the product.

Overall, stakeholders are strongly encouraged (via the opportunity for credits) to seek out and use products whose environmental impacts and supply chain have been externally verified according to industry-approved standards. At this early stage, having the documentation itself is arguably more important than what it says. Several of the credits can be earned regardless of the results.

For example, two products with externally verified EPDs contribute to the several of the same points, even if one has a significantly higher carbon footprint. (The product with the lower carbon footprint might also be able to contribute to other points.) At present, the goal is to promote transparency. Once this has become standard practice, it is conceivable credits will start to emphasize environmentally preferable products. In the meantime, the information is available Materials • Technolog y • Trends

for consideration, enabling specifiers to choose environmentally preferable products, even if the reduced environmental impact is not required to earn certain MR credits.

Catalyst for change The overarching result of LEED v4’s shift in focus is the specification of more transparent products – those that take the holistic approach of life cycle assessment and look beyond single attributes. This allows users to understand where environmental tradeoffs might exist so the best decisions can be made for each specific project.

Eventually, the building industry might follow the path of the food industry: The FDA developed a standard nutrition label for foods so consumers can make informed comparisons. Product users would like to see building products more comparable, so it is easier to understand the impact of products. Where food labels contain fat content and calorie count, product labels might spell out fossil fuel consumption and recycled content. Just as some consumers might watch sodium or sugar intake depending on personal needs, some specifiers might be more concerned with carbon footprint or water resources, depending on project needs.

The new system also allows innovative products with reduced energy use, carbon footprint, and other environmental impacts to contribute to a variety of credits. In previous versions of LEED, there were no formal credit opportunities for these types of products, other than Innovation in Design credits.

Challenges remain As with any major change, there are drawbacks. Possibly the biggest concern is the relative dearth of products with LCAs and published EPDs or HPDs. Further, finding them isn’t as straightforward as it could be. There’s no master list to discover EPDs across the industry. (Each EPD program operator has a list, but there are numerous EPD program operators.) The onus is on specifiers to perform the extra research in pursuit of increased sustainability.

However, demand for these tools is increasing. Last year, the concrete industry finalized Product Category Rules (PCRs) for concrete, which laid the groundwork for concrete manufacturers to conduct individual LCAs and publish EPDs. In addition, PCRs have recently been finalized for concrete masonry units. In late-2012, CalStar Products published the first EPD in the brick category, with the document providing third-party verification of environmental impacts. CalStar bricks also received a SMaRT sustainable product platinum rating, indicating significant reduction in environmental impact, as well as supply chain transparency and minimization of harmful chemicals. These documents together allow CalStar bricks to contribute to a variety of MR credits under LEED v4.

Similar advances are underway in other product categories, as well, particularly carpet, gypsum, and wood.

Like the recycled content credits that initially drove industry change, USGBC’s Buffaloe expects LEED v4 to do the same: “Transparency enables evaluation…which enables preferential selection…which leads to innovation.

And innovation leads back to reporting and transparency. It’s a cycle of its own resulting in market transformation.”

Perhaps, 14 years from now, we’ll view LCAs and EPDs as commonplace and straightforward as trying to use more recycled materials and sourcing locally. wMD

PROJECT SPOTLIGHT IT’S NOT EVERY DAY THAT ONE RECEIVES A CALL FROM A PRIEST REQUESTING ONE’S DESIGN SERVICES FOR A NEW CHURCH. But if that day comes, you’re certainly going to pick up the phone.

That’s exactly what Duncan G. Stroik, Architect, LLC., did in 2012.

According to the firm, the pastor of the Saint Paul the Apostle Catholic church in Spartanburg, S.C., was familiar with its award-winning work and wanted the firm to design a new place of worship for his growing congregation. Between June 2012 and December 2013, Duncan G. Stroik completed all of the design work and oversaw construction of the $8.2-million project. In the firm’s own words, this is how the new church came together.

The traditional style of the church extended beyond its aesthetic appearance and included the choice of building materials and construction method.

Saint Paul the Apostle Spartanburg, S.C., is a charming city of 37,000 residents and counts a large number of fine churches among its historic buildings. The downtown Catholic parish of Saint Paul the Apostle had by the mid-1990’s outgrown its small historic church built in 1883. For the past 20 years, the masses had been held in the school gymnasium. Thus, the pastor wanted a new church that would be large enough to accommodate his congregation – a facility designed to lift their hearts and minds to prayer.

To build the larger church, the parish decided to take advantage of its urban location on a prominent site on East Main Street. The traditional design of the

PROJECT SPOTLIGHT row of intricate brick arches, and a painted metal Celtic cross surmounting the pediment, complete the façade.

Materials A masonry structural system was selected for its durability, natural sustainability, and cost effectiveness.

Based on two cost estimates, it was less expensive to build with masonry than it would have been to use structural steel. The aesthetic of the red brick Romanesque façade with limestone accents also was very appealing to the client. The marble used in the interior was concentrated in the sanctuary, which is the most important part of a church during the liturgy. Therefore, a higher-quality material was appropriate for that location.

The structural system is made up of a brick cavity wall with CMU backup. Limestone detailing was used on the exterior of the church, as well as for the three carved statues of Paul, Peter, and Mary. Inside, marble was used for the main altar and baldacchino column pedestals, the altar for the tabernacle, two side altars, the sanctuary floor and steps, and the altar rail.

By the Numbers Project scope: 1 8,000 sq-ft, 850 seats

Construction cost: $8.2 million Design challenges Duncan G. Stroik designed the brick layout for the building down to the last brick. Further, the architect designed the building with a load-bearing masonry structural system. After an initial cost estimate, the estimator suggested it would be cheaper to use a structural steel system. The architect re-designed the building using structural steel, including a revised brick layout. After a second cost estimate, however, it was discovered that the new system was actually more expensive, so the team decided to go back to structural masonry.

During construction, it was difficult for the bricklayers to match the brick layout completed by the architect; the brick layout was more complex and precise than previous projects the contractor had completed. Several areas of installed brick had to be rebuilt during construction to match the architect’s details, such as the Flemish bond and the round window of the front façade. But in the end, it all came together beautifully. wMD

RESTORATION

STANDING THE TEST OF TIME Restored Astley Castle recipient of prestigious Riba Stirling Prize for Architecture

By Cory Sekine-Pettite Credit: All photos courtesy of The Landmark Trust.

CINTEC INTERNATIONAL, A LEADER IN THE FIELD OF STRUCTURAL MASONRY RETROFIT STRENGTHENING, REPAIR, AND PRESERVATION, reported recently that its patented anchors were used in the restoration of Astley Castle in Warwickshire, England. Following its renovations, Astley Castle was awarded the prestigious Riba Stirling Prize for Architecture.

The castle dates back to the 13th century, and was on the verge of collapse following a fire in 1978. In the 1990s, the property came to the attention of The Landmark Trust, which vowed to restore the neglected castle. Today, it is used as a rental property for tourists. The Trust says of the landmark: “Groundbreaking modern accommodation has been inserted within the ruined walls of this ancient moated site to combine the thrill of modern architecture with the atmosphere of an ancient place.”

RESTORATION According to the Trust, the site includes the moated castle, gateway and curtain walls, lake, a church, and the ghost of pleasure gardens in a picturesque landscape. In 2005, the Trust launched an open competition to find the best restoration plan that would create good, modern accommodation within the ancient ruins. The winning scheme, the Trust reports, by architects Mann Williams, maintains the sense of life and living within the castle, while making the most of the views – both into and out of the site.

As The Landmark Trust explains: “After careful recording, those parts of the building beyond pragmatic repair were taken down. The new-build introduced also consolidates and ties together what could be saved of the original fabric as

unobtrusively as possible, leaving the castle’s form in the landscape largely unchanged. There was further work on the wider setting, including repairs to the curtain walls and moat, and the 18th-century Gothic stable block. The historic parkland surrounding the moated site, much of which is a Scheduled Monument, has been opened up with public trails.

The restoration Cintec teamed up with architects and engineers from Bathbased Mann Williams and Newport-based waterproofing engineers Protectahome to restore the castle. Cintec assisted Protectahome with the first phase of the nearly $4-million restoration, which included structural repairs and stabilizing the remaining walls of the building prior to rebuilding. Cintec’s patented anchors were used to stitch together and strengthen the walls.

Protectahome was brought in to complete the initial stage of stabilizing the remaining walls of the listed building prior to restoration.

According to the firm, its technicians installed more than 160 consolidation and stitching Cintec anchors, including two, 12-meter anchors.

The process of restoring Astley Castle involved using a diamond drill to insert steel anchors into the building. Once in place, grout was pumped into a special sleeve surrounding the anchor, and air pumped out. Cores removed during this process were retained and reused where the anchors were installed, leaving an almost invisible repair. The work has ensured the survival of the original walls, allowing the award-winning holiday home to be built within the shell of the ancient castle.

The Riba Stirling Prize is the UK’s most prestigious architectural award. Judging is based upon original, imaginative, and well-executed designs that excellently meet the needs of their users and inspire those who use and visit them.

“The restoration work on Astley Castle was an impressive enterprise, as anyone who saw the castle prior to its transformation could have been forgiven for thinking it a hopeless ruin,” said Peter James, managing director of Cintec International said.

“To be awarded the Riba Stirling Prize demonstrates the true extent of its transformation. It has now been turned into a structurally stable building that will stand the test of time and can be enjoyed by many people in its reincarnation as a holiday home.”

Cintec anchors have been used to restore historically significant buildings across the globe, including Windsor Castle, the White House, and extensive work on Egypt’s pyramids.

“To be awarded the Riba Stirling Prize demonstrates the true extent of its transformation.” – Peter James

Astley Castle history The Landmark Trust provides an extensive history of the castle on its website. Here are a few excerpts: By the early 12th century, the castle was held by Philip de Estlega (Astley) from the Earl of Warwick. Philip’s grandson Thomas de Estleye was killed at the Battle of Evesham fighting with Simon de Montfort in 1265. The castle was crenellated [having open spaces at the top of a wall so that people can shoot guns and cannons outward] and moated in 1266, when it briefly changed hands before reverting to the Astleys. By 1420, the manor had passed through marriage to the Grey family and became entangled with the succession to the throne of England.

It was under the Greys in the late 15th century that the castle achieved its most mature form. However, after the death of Edward VI in July 1553, Henry Grey, Duke of Suffolk seized the initiative and placed his daughter, Lady Jane Grey, on the throne. Jane’s reign lasted just nine days, before Mary I’s superior claims prevailed. Both Jane and later her father were beheaded for treason – Lord Grey rebelled a second time in January 1554 and was captured in a hollow oak tree at Astley.

In 1600, the castle was bought by Sir Edward Chamberlain. The Chamberlains restored the church and improved the castle. During the Civil War in the 1640s, Astley became a garrison for Parliamentary soldiers. In 1674, it was bought by the Newdigate family, who owned the neighboring Arbury Estate, and the castle became a subsidiary dwelling. In the 1770s, a Sir John Astley leased the castle briefly and was responsible for the construction of the stables and coach house.

Requisitioned during World War II for convalescing service men, a dilapidated Astley Castle was restored by the Tunnicliffes in the 1950s as a hotel. The castle completed its slide from grace when it was gutted by a mysterious fire in 1978, just days after its lease had expired. Vandalism, unauthorized stripping out, and collapse made its plight still worse. For many years, no solution could be found to give it a future and Astley Castle became a ruin. By 2007, English Heritage had listed it as one of the 16 most endangered sites in Britain. wMD w w w.masonr ydesignmaga zine.com

Supplies | Air, Vapor, & Water Barriers As defined by the Air Barrier Association of America, air barrier systems are comprised of a number of materials which are assembled together to provide a complete barrier to air leakage through the building enclosure. This system essentially “wraps” the building shell and ensures that it protects the building from the effects of air leakage. Air leakage can have detrimental effects on how a building functions and reduces the life span of a building.

1 Enverge™ Air and Vapor Barrier http://firestonebpco.com

Firestone Building Products’ Enverge Air and Vapor Barrier is an asphalt-based, self-sealing wall barrier that provides energy savings and contributes to better air quality for building occupants. According to the manufacturer, this system offers the following advantages: • Reflective facer provides energy savings • Self-sealing barrier • Consistent membrane thickness • Minimizes drafts and reduces moisture to guard against mold • Meets or exceeds ASTM D5602, D1876, D903, E283, E96, and E330.

Installation considerations include: • Surface must be primed with an Enverge primer • Remove the release liner at a 45° angle in 3” increments to promote correct alignment and installation continuity • The membrane should be firmly rolled from the center to the outside for maximum adhesion • Seams should overlap a minimum of 2” for effective coverage • Self-seals around mechanical fasteners and minimizes air leakage around open gaps; foil flashing tape can also be used to seal penetrations.

2 Driwall™ Rainscreen

http://www.keenebuilding.com

Keene Building’s Driwall Rainscreen system is a drainage mat for exterior wall systems. The entangled net product eliminates incidental moisture problems in most exterior veneer applications, including stucco, manufactured stone, and plank siding. Driwall Rainscreen is produced from an extruded polymer matrix of tangled monofilaments. The three-dimensional mat is heat-laminated to a non-woven lightweight, breathable fabric to provide a separation from cementitious sidings. The monofilaments are heat-welded at the junctions to form a structure that spaces exterior veneer away from the inner sheathing.

http://thermafiber.com

Thermafiber RainBarrier products from Owens Corning are designed for exceptional performance in rain screen and cavity wall construction applications. New RainBarrier HD & RainBarrier 45 provide energy-saving continuous insulation (ci), fire protection, and acoustical control while efficiently draining water from a wall cavity system. RainBarrier products are non-combustible and compatible with common wall ties and air barrier systems.

According to the manufacturer, RainBarrier has several distinct advantages over other insulation products in these types of construction: 1. Non-combustible and fire resistant. RainBarrier can withstand temperatures over 2,000°F for over 5 hours. In the event of a fire, mineral wool will not burn or release toxic smoke and gasses.

2. Sustainability. Available with a minimum 70% recycle content. No CFC or HCFC blowing agents.

Energy saving R-value of 4.2 per inch of thickness.

3. Permeable. In a vapor permeable system, RainBarrier allows the building to breathe as it is designed without sacrificing R-value. In a nonpermeable system, RainBarrier allows the vapor barrier to perform without creating additional traps for moisture in the wall cavity.

4. UV resistant. RainBarrier is ideal for use in open joint systems where UV rays can degrade other insulations.

5. Easy to fabricate and install. Semi-rigid mineral wool can conform to jobsite irregularities much better than rigid insulations to ensure a continuous thermal barrier.

4 PROSOCO R-Guard Spray Wrap MVP

®

www.prosoco.com PROSOCO R-Guard® Spray Wrap MVP is a fluid-applied air and water-resistive barrier that stops air and water leakage in cavity wall, masonry veneer construction, as well as in stucco, EIFS and most other building wall assemblies. Once on the substrate, the easily applied liquid quickly dries into a rubberized, highly durable, water-resistant, vapor-permeable membrane.

Use Spray Wrap MVP as a high-performing, water-resistive barrier or as part of a continuous, building-wide air barrier system. The durable membrane conforms and adheres to common building surfaces and is compatible with most paints, sealants, and self-adhered waterproofing or air barrier components. It is appropriate for vertical, above-grade applications to exterior sheathing, CMU, cast concrete, and most other common building materials. wMD w w w.masonr ydesignmaga zine.com
