Walltite spray foam insulation from BASF Polyurethanes has been used to form an airtight thermal-efficient envelope at the BRE’s Victorian terrace retrofit demonstration project, in Watford

After the old plaster was hacked off the walls the system was applied directly onto the rough, bare brick substrate without the need for primer or levelling coat to a thickness of 100mm.

Walltite is a closed cell foam, the structure of which helps control the movement of vapour and moisture throughout the building thus reducing the risk of mould and condensation. At a thickness of 100mm it achieves a U-value of 0.24W/m2k.
