The Marshall Building, part of the renowned London School of Economics has been fitted with the Wraptite external air barrier system from the A. Proctor Group. Wraptite is the only self-adhering vapour permeable air barrier certified by the BBA and combines the critical properties of vapour permeability and airtightness in one self-adhering membrane. This approach 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 Approved Document B Building Regulations 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.
