Wraptherm from A.Proctor Group has been awarded certification from both LABC and LABSS, confirming that the product meets building regulation approval in England, Wales and Scotland.
Improving airtightness levels, whilst at the same time addressing the need to reduce thermal bridging in refurbishment projects, the high-performance membrane composite is self-adhesive, and is specifically developed to be applied during the refurbishment of existing buildings where there is a requirement to enhance the thermal and airtightness performance of the building.
Wraptherm can also be used in newbuild construction where the reduction of thermal bridging and improving the airtightness is required, e.g. around steel lintels or around concrete columns.
It consists of a 10mm Spacetherm aerogel insulation blanket bonded to the face of Wraptite, the vapour permeable, self-adhesive airtight membrane.
When applied to the internal face of the existing façade, Wraptherm provides a vapour permeable yet airtight layer, that is fully self-adhered to the substrate beneath with the added benefit of a 10mm thick layer of high-performance Spacetherm insulation blanket.
Over this airtight/thermal composite framing can then be installed with the added benefit of a reduction in thermal bridging due to the Spacetherm layer. Where required, additional thermal insulation can be included within the frame to meet the specific U-value requirements of the project.
The offset nature of the Wraptite component allows for a completely robust sealing of all of the joints within the panel, thereby ensuring the continuity, integrity and robustness of the airtight layer.
