Week 8: Openings eLearnings • Doors and Windows • Door Types • Glass Doors • Weather Stripping • Window Elements • Window Types • Glazing Systems • Skylights • Sunspaces


ENVS 10003 CONSTRUCTION LOG BOOK eLearnings Doors and Windows Overview Provides access form the outside to the interior swell as passage between interior spaces -located appropriate to the usage patterns and activities of the inhabitants -exterior doors should be weather tight and maintain approximate thermal insulation values as the surrounding walls -doors should be bespoke to • deserted degree of visual and acoustic privacy • ease of operation • durability under the anticipated frequency of operation • security provisions • ventilation • view • emergency and safety requirements _2009_002.26122305.JPG



Door Type Operation Swinging -Turns on hinges about the door jamb -most effective for thermal and acoustic -can be fire and explosive resistant


ENVS 10003 CONSTRUCTION LOG BOOK Bypass Sliding -slide on overhead track and runners or separate side beneath -no operating space but difficult to weatherproof -ineffective use of space-access only through 50% of the doorway Surface Sliding -provides access to the full width of the doorway -surface hung sand difficult to fully insulate


ENVS 10003 CONSTRUCTION LOG BOOK Pocket Sliding -slides on an overhead track in and out of access way on the internal wall -often used where folding door would interfere with use of space

Folding Doors -Hinged panel that fold flat against each other when opened -Bi-folding doors divide into two parts, require little operating space and are used primarily as visual screen to enclose closet and store spaces


ENVS 10003 CONSTRUCTION LOG BOOK Wooden Doors Hollow Core Doors -Frame work of stiles and framework encasing an expended honeycomb core of corrugated fiber board of a grid of interlocking horizontal and vertical wood strips -Light weight but have little inherently thermal or acoustic value -Primarily interior but can be sued on the exterior is coasted with water proof adhesive Solid Core Doors -Core of bonded lumber blocks -Use primarily as exterior doors, but may also be sued where increase fire resistance, sound insulation or dimensional stability is required 94

ENVS 10003 CONSTRUCTION LOG BOOK Batten Doors -Vertical board sheathing nailed at right angles to cross strips or ledgers -Diagonal bracing is nailed between or notched into the ledgers -Used as exterior doors for right environments e.g. farms -Tongue and groove timers are recommend for weight efficiency Grades and Finished -Stain -Paint -Timber veneer/high pressure plastic laminates


ENVS 10003 CONSTRUCTION LOG BOOK Glass Doors -Constructed from high strength or tempered glass -may be offset in frame to swing in one direction or be center hung for double acting operation -may be set on a pivot-opposed to hung or hinges Revolving Doors -Consist of various leaves (dependent on the size of the door) that rotate about a central, vertical pivot within a cylindrically shaped vestibule -provide a continuous weather seal, eliminate drafts and hold heating and cooling losses -regulate the pressure differential between the interior and exterior of the structure-provides a continuous passage way between interior and exterior whilst not exposing one to the other-preventing pressure differential transfer 96

ENVS 10003 CONSTRUCTION LOG BOOK Weather Stripping -consists of metal, felt, vinyl, or foam runner strips placed between the door or window sash and its frame -act as a seal between internal and external environments -material should be durable, non-corrosive and replaceable Thresholds -Cover the joist between two flooring materials at door ways and serve as a weather barrier at external sills -Recessed underneath for a clean fit to maximize insulation properties 97

ENVS 10003 CONSTRUCTION LOG BOOK Windows Window Elements Rough opening -Opening in the superstructure for the window to sit -Space is required at the top, sides and bottom for leveling and shimming of the window unit

Window Frame -Frame in whack the sash and window glazing sits -Sash is fixed to the frame and the frame fixed to the rough opening -Can be variety of material but most commonly aluminum or timber -Head is the uppermost member of the window frame -Jamb is wither of the two side members -Sill is the horizontal member beneath the window or doorusually sloped to shed rainwater -Sub sill is fitted for drip protection -Section between window frame and the rough opening should be sealed for thermal insulation and weather tightness

Sash and Glazing -Sash: fixed, movable frame work of a window in which the panes of glass of material sit -Glazing: panes or sheets of material in the sashes of the window-single glazing, double glazing or triple glazing -Operating sash should be weather stripped against windblown rain and air filtration

Casing Trim -Finished trim work around the window opening -Usually internal-used little externally -Provided a physical barrier and cover over the gap between the rough opening, window frame and window sill



ENVS 10003 CONSTRUCTION LOG BOOK Types of Windows Metal Windows -May be fabricated form aluminum, steel or bronze-or a composite alloy Considerations: • details of frame and sash profiles • weight and thickness • thermal performance sod deserted assembly • resistance to corrosion and surrounding environment • glazing methods and options • finished Aluminum Windows -Relatively low in cost, lightweight, resistant to corrosion as they are such efficient conductor of heat, thermal breaks and synthetic insulators are required to interrupt the flow of heat -Have baked enamel or fluoropolymer resin finishes


ENVS 10003 CONSTRUCTION LOG BOOK Steel Windows -Manufactured from hot rolled or cold rolled steel -More rigid and thinner in profile then aluminum -Larger panes to be installed due to their strength -Lower conductivity or heat-minimise thermal breaks

Timber Windows -Thicker, more effective as thermal insulators -Treated in a water repellant preservative -May be primed, stained or painted -Bonded with acrylic painted to minimise maintenance 101

ENVS 10003 CONSTRUCTION LOG BOOK Glazing Systems Face Glazing -Small glass frames may be set in a rabbet frame, held in place with glaziers points, and sealed with a beveled bed of putty or glazing compound /s1600/WP_20130811_17_44_42_Pro.jpg

Wet Glazing -Setting of glass in a window frame with glazing tape or liquid sealant


ENVS 10003 CONSTRUCTION LOG BOOK Dry Glazing -Getting of glass in a window frame with a compression gasket instead of glazing tape or liquid sealant Insulating Glass -Consists of two or more sheets of glass separated by a hermetically sealed air space -This provided increased thermal insulation and restricts condensation -For improved thermal efficiency, tinted, reflective or low emissivity (low-e) glass may be used


ENVS 10003 CONSTRUCTION LOG BOOK Glazed Curtain Walls -Exterior, non-load bearing walls consisting of vision glass or opaque spandrel panels supported by metal framing -Types: Stick Systems -Tubular metal mullions and rails assembled piece by piece on site to frame vision glass and spandrel units -Versatile and site adjustable

Unit Systems -Consist of reassembled, framed wall units which may be pre glazed or glazed after installation -Larger, heavier and less effected construction system compared to stick system

Unit and Mullion System -One or more two story high mullions are installed before preassembled wall units are lowered into place behind the mullions

Column-Cover-and-Spandrel System -Consist of vision glass assemblies and spandrel units supported by spandrel beams between exterior columns clad with cover sections


ENVS 10003 CONSTRUCTION LOG BOOK Skylights -Allow daylight to enter through roofs structure -Carful consideration should be paid to the control of brightness and glare -South facing skylights also increase solar heat gain during the winter months -Requires a frame roof opening-both the support roof structure and the skylight units must been engineered to carry the anticipated roof loads Types


ENVS 10003 CONSTRUCTION LOG BOOK Sunspaces -Glass enclosed porch or room adjoining another living space oriented to admit large amounts of sunlight -Often used in conduction with solid thermal mass to increases net heat gain -Due to the probability of overheating, precautions towards shade, ventilation and operable windows should be considered
