WALLTITE®
Spray Foam Insulation

Existing timber suspended floor (cellars)

WALLTITE® floor insulation is advisable where underfloor heating is installed. The foam barrier separates heated and unheated rooms and in this way, reduces any loss of valuable heating energy into spaces where it is not needed. Rooms with just occasional use benefit from WALLTITE® insulation, as the floor heats up more rapidly.
