Wraptite® Protection Chosen For Isle Of Man Seafront Property The Wraptite external air barrier system from A. Proctor Group, selected as part of the façade upgrade to a sea-facing property in Douglas, Isle of Man, will ensure energy efficiency and protection from the elements. The Peveril Buildings is situated in the centre of the Isle of Man’s Business District, opposite Douglas Sea Terminal. Based in Ballasalla on the island, Excel Construction Group was appointed to upgrade the facade and improve the building’s structure, aesthetics, and energy efficiency. Andrew Burley, Quantity Surveyor at the Excel Group, explains why Wraptite, the only self-adhering vapour permeable air barrier certified by the BBA, was selected. “We chose Wraptite for the breather membrane because of its effectiveness as a vapour barrier and durability. In addition, the nature of Wraptite, being a self-adhesive fix rather than the traditional use of staples and mechanical fixing, assisted with the durability in the high wind conditions prevalent on the seafront location.” Wraptite combines the critical properties of vapour permeability and airtightness in one self-adhering membrane. Incorporating Wraptite saves on both the labour and material costs associated with achieving the energy efficiency demands in buildings. Wraptite is Class B1-s1,d0, compliant with Part B regulation changes for use in the external wall systems of buildings over 18m in height, both as a continuous layer on sheathing board behind fire classified insulation, and for use to tape joints in insulation behind rainscreen. www.proctorgroup.com
Marmox Thermoblocks Specified On Wigan Passivhaus Development The final phase of a PassivHaus development is just getting under way in Wigan with high performance Thermoblocks from the range of Marmox being used to counter cold bridging beneath a highly insulated timber frame construction. The St. Mary’s project is being under taken for Wigan Metropolitan Borough Council by principal contractor, Tyson Construction with Pozzoni Architecture being the lead architectural consultant and BTP Architects gilling the roll of specialist PassivHaus assessor. All of the Thermoblocks in 100mm and 140mm widths, along with boxes of the special Marmox 360 adhesive are being supplied by Travis Perkin’s Blackpool branch. The scheme to provide much needed affordable and easy to heat new homes has been part-funded by the Government’s Department for Levelling Up, Housing & Communities. The Site Manager for Tyson Construction, Matt Horrocks, commented: “For fitting the timber frame soleplates it is necessary to do a ‘setting out’ course across the block-and-beam, with the dense concrete block serving to contain the screed. The 140mm Thermoblocks are laid beneath all the external walls, followed by a 140 common brick course and then the standard blocks. This is repeated for the internal and party walls, but with a course of 100 mm Thermoblocks creating the fully insulated barrier.” When complete the development will provide eight one-bed apartments, nine two bed houses and ten three bed houses, plus a further four with four bedrooms. There will also be 16 one and two bedroom bungalows. www.marmox.co.uk
