Wraptite THE AIRTIGHT AND VAPOUR PERMEABLE MEMBRANE

The A. Proctor Group Ltd, a familyowned company in its fourth generation, has been providing solutions and products to the construction industry for over 50 years. In buildings, air leakage normally manifests itself as uncontrolled flow of air through gaps and cracks in the fabric. The result shows significant reduction in the thermal performance and efficiency of structures. The construction industry, driven by increasingly rigorous regulations and the overall energy-efficiency agenda, is putting the creation of airtight buildings at the top of the agenda, in refurb as well as new build....

Wraptite-SA combines important properties of vapour permeability and airtightness in one affordable selfadhering membrane. It fully bonds (needing no mechanical attachment) to virtually any substrate, with a key benefit being its ease of installation, negating requirement for sealants or tapes. WRAPTITE-SA OFFERS A COMPELLING COMBINATION Wraptite-SA airtight membrane makes a significant contribution to a building’s thermal performance by preventing lateral air movement, but it also contributes to a healthy living environment and a healthy building, thanks to its vapour permeability. With a...

Hydrophobic outer layer repels liquid water Airtight core stops movement of warm/cold air Vapour permeable structure releases moisture from building envelope Patented vapour permeable adhesive A practical test of the extent of air leakage through a buildings fabric is an important part of ensuring “as built” performance come as close as possible to the design performance targets. Such testing also allows contractors to identify air leakage paths within the building, allowing them to take appropriate remedial action if the design targets are not met. Wraptite-SA Detail The methods governing...

Wraptite System Introduction WRAPTITE SYSTEM The Wraptite system offers the ideal option for a vapour permeable air barrier. Designed to cost effectively replace traditional airtightness methods., Wraptite is a low-resistance vapour permeable air barrier wall underlay, which is durable, flexible and lightweight, allowing for easy installation. It offers temporary protection against wind-driven rain, snow and dust. The Wraptite system comprises Wraptite plus Wraptite Tape. Used together these components provide a simplified and robust method of achieving low air leakage rates, particularly...

Wraptite Tape Introduction WRAPTITE TAPE A useful way of stopping unnecessary air leakage around openings and overlaps is to use Wraptite tape, an airtight, tear resistant tape with high vapour permeability for internal and external applications. It fully bonds to all standard substrates, suppressing air leakage around joints, openings and penetrations. It is also suitable for permanent airtight sealing of membrane overlaps. Composition Wraptite Tape consists of a triple layer polypropylene micro-porous film laminate, with a proprietary acrylic moisture vapour permeable adhesive and...

APPLICATIONS Penetrations in sheet material such as pipes, ducts and electrical work need to be sealed to stop air leakage from the structure. Horizontal over sheathing Pipe seal Seal joins of rigid insulation with Wraptite tape / or use Wraptite-SA Vertical over sheathing Floor junction on installation Detailing with Wraptite tape is quick and easy, providing an excellent solution to what can be an expensive problem.

SUNSHINE MOSQUE, MELBOURNE Proctor Wraptite-SA airtight membrane was used as part of the refurbishment of the Sunshine Mosque’s dome in Melbourne, Australia. The Sunshine Mosque is an Ottoman/Turkish-style mosque in Sunshine, a suburb of Melbourne. This complex structure comprises of seventeen domes, a minaret, and a courtyard. The complex existing concrete domes were leaking and needed to be re-roofed in Zinc. As part of this refurbishment, a watertight underlay and separation layer was required to be placed underneath the VM Zinc Plus. Wraptite-SA was identified by our Australian...

AIR-TIGHT MEMBRANE USED ON LOG CABIN The A. Proctor Group Ltd recently supplied Wraptite-SA for a log cabin construction in Corgarff, Aberdeenshire. With Wraptite-SA being such a versatile product, previously dated construction techniques have became viable once again. A prime example of this is Sylvan Stuart’s innovative application of Wraptite-SA in log cabins. Doug Irvine from Sylvan Stuart Ltd explained “The job at Corgarff is built using our double-skin log construction. This has evolved since it was developed back in the eighties as the building regulations have demanded since then....
