Proctor Group has, for 50 years, been serving the construction industry with an extensive portfolio of technically advanced thermal, acoustic and membrane products. Founded in the German city of Darmstadt in the 1990s, the Passivhaus Institute aims to develop and promote best practice ideas in low energy housing design. These ideas are codified into the...

Passive House Construction The Passive House concept is founded on five basic principles for good design: • • • • • Thermal Insulation Thermal Bridge Free Design Airtightness Ventilation and Heat Recovery Passive House Windows These five simple ideas, properly applied in a well constructed dwelling, facilitate a dramatic reduction in the energy required for space heating. This is achieved by maximising solar gains and harvesting waste heat, whilst minimising all mechanisms of heat loss from the envelope. These are by no means new ideas, but todays increasing focus on both housing quality...

FABRIC INSULATION THERMAL BRIDGING PRODUCT SOLUTION PROVIDERS

FABRIC INSULATION Thermal insulation is what limits the loss of heat from the building envelope, and is the cornerstone of the fabric first approach to building design. This approach seeks to maximise the performance of the basic components of the building, rather than relying on mechanical or electrical systems. Limiting the thermal transmittance, or U-value, through roofs, walls and floors, while minimising the loss of space and ensuring moisture flows are properly managed is the principle challenge of low energy housing design. THERMAL BRIDGE FREE DESIGN A thermal bridge occurs either...

External Airtight Membranes - an Introduction Why are airtight membranes needed? Air leakage through cracks, gaps, holes and improperly sealed elements such as doors and windows can cause a significant reduction in the performance of even thermally insulated building envelopes. Housebuilders have a key role to play in the installation of effective air barrier systems which have become essential in achieving the most effective means of controlling and reducing air leaks. As thermal insulation requirements have increased over the last few years, the proportion of energy lost through air...

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. Wraptite airtight membrane makes a significant contribution to a building’s thermal performance by preventing lateral air movement,...

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. It fully bonds to all...

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 our vapour permeable products for joint detailing in exterior sheathing panels. Wraptite Liquid Flashing is ideal for use in complex details. It can also be used to protect the leading edge of the Wraptite membrane or tape from water penetration if the edge...

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 barrier performance as the Wraptite membrane...

Procheck Adapt is a high performance variable-permeability vapour control layer for use in a variety of commercial and residential applications. It is designed to protect the building fabric from potential risks of condensation and it will also act as an airtight barrier. Its variable permeability adapts to changes in humidity levels becoming more resistant in Winter and more permeable in Summer. This means the building fabric is protected from damaging moisture levels during cold, wet months of the year and it will allow the fabric to dry out effectively in warmer, drier months. Procheck...
