Existing timber suspended floor (cellars)

Description

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.

Certification

WALLTITE has undergone various performance tests.
Certificates are available on request.
