THE SELF-ADHERING AIRTIGHT AND VAPOUR PERMEABLE MEMBRANE

The A. Proctor Group Ltd, a familyowned company in its fourth generation, has been providing technical solutions and specialist products to the construction industry for over 50 years. In the 21st century the increasing focus on emissions reduction and energy efficiency has led to the development of specialist construction membranes aimed at reducing energy use by limiting air leakage. A large proportion of UK CO2 emissions are associated with the built environment, of which surprisingly little comes from the design and construction phases. The majority is generated by the ongoing requirements...

Wraptite The self-adhered nature of Wraptite allows for a simple and fast installation process, minimising the use of additional sealants and tapes, and requiring no specialist contractors to achieve a robust result. This one-step solution provides both a damage resistant air barrier layer and effective secondary weather protection in one installation process, allowing a wind and watertight envelope to be achieve more quickly than using traditional methods. • Self adhered • Airtight yet vapour permeable • BBA Certified (Cert. No. 15/5274) • Tough 3-Layer Laminate resists punctures and tears •...

Wraptite Roofing WRAPTITE FOR ROOFING Where a full wall and roof airtight envelope is required Wraptite can be used in both applications. The self-adhered backing not only ensures an airtight seal but resistance at laps against water penetration, dust, air infiltration and wind resistance making it an excellent choice for this application. • Self adhered • Airtight yet vapour permeable • No ventilation required • Can be used in all wind zones • No maintenance required • Class B, s1 d0 in accordance with BS EN 13501-1:2007 • BBA Certified (Cert. No. 15/5274) • Tough 3-Layer Laminate resists punctures...

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. Wraptite Tape’s flexibility facilitates ease of application and detailing, while its resilient composition resists punctures and tears during construction. It can be left exposed for up to 120 days during construction and has a wide operating temperature range (-40°C to +100°C). Wraptite Tape is also available with a split release liner for ease of installation - see below. It fully bonds to...

Wraptite System Components WRAPTITE LIQUID FLASHING Wraptite Liquid Flashing is a high-quality, gunable, elastomeric, polyether, liquid applied flashing and detailing membrane. It bonds to most construction materials, such as aluminium, brick, concrete, wood, vinyl, and exterior sheathing boards. Wraptite Liquid Flashing is compatible with the entire line of A. Proctor Group’s vapour permeable products for joint detailing in exterior sheathing panels. Wraptite Liquid Flashing is for use with A. Proctor Group’s range of vapour permeable membranes. This liquid applied flashing membrane is ideal...

Wraptite-FZ linked to VCL with Reflectafoil Tape or Probond RG Tape Breather Membrane Wraptite-FZ is a vapour permeable air barrier membrane for use at floor junctions. It is durable, flexible and lightweight, and offers temporary protection against wind driven rain, snow and dust and is supplied in 750mm roll widths for easy site handling. Wraptite-FZ conforms to the Construction Products Directive and is manufactured under control of an ISO9001 quality management system. Test Method Roll size Mass per unit area Water vapour resistance Sd Water penetration Before ageing Class W1 After ageing...

System Components Wraptite Corner WRAPTITE CORNERS Wraptite Preformed Airtight Corners have been developed for the difficult areas around doors and windows where maintaining good air barrier continuity is difficult and time consuming. Wraptite corners’ simple design and installation process makes sealing openings against air leakage simple, just peel off the release liner, stick the corners in place, then install the Wraptite membrane as normal. This helps achieve the best possible results in the shortest possible time. Once installed, the corner sections provide the same vapour permeable air...

Wraptite Passivhaus is a low energy construction standard where the building requires very little energy for heating or cooling. To achieve this, the building must have excellent thermal performance with exceptional airtightness. The UKs first permanent Passivhaus show house, has been built by Potton using the Kingspan TEK® Building System. It joins four existing show homes at their Self Build Show Centre in St Neots and utilises Wraptite air barrier membrane, supplied by the A. Proctor Group. Case Study Potton Passivhaus Showhouse, St Neots Wraptite is both vapour permeable and airtight, combining...
