Wraptite - LSE, London

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.

Part of a winning design created by Grafton Architects, the impressive 10-storey building features pale stone cladding and is home to a series of educational facilities including lecture theatres, offices, classrooms, and a sports hall.

Specialist contractor, I & S Construction, Dartford consulted with the A. Proctor Group’s technical team and selected the Wraptite air barrier to be incorporated within the external wall cladding system.

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.

Glenn Giddens, Project Manager of I &S Construction, commented: The Wraptite self-adhesive membrane could be applied externally, quickly and efficiently providing a high quality installation and robust through wall cladding system, without the additional need for mechanical fixing required using a standard membrane.”

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.
