Technical Data

Technitherm® is a CFC and HCFC FREE dual component polyurethane foam which complies with the requirements of BS 7457:1994 for the stabilisation and thermal insulation of masonry cavity walls.

Technitherm® is used for the stabilisation of masonry cavity walls by strongly adhering the inner and outer leaves together and as such is a convenient and cost effective alternative to metal cavity wall tie replacement.

Its excellent thermal insulation properties means improved U-values are achieved. For a standard construction 65 mm cavity U-values of 0.33 Wm²K are achieved and in a 100mm standard construction cavity the U-value is 0.22 Wm²K.
