Thermal Upgrading Systems for Concrete Decks

Promat TL Board® Introduction Promat TL Board® is a calcium silicate board bonded to phenolic insulation and is designed to be fixed to the underside of floors (generally concrete) to achieve specific U-values required by the project design and Building Regulations. There is an increasing requirement for the thermal upgrading of semi-exposed concrete decks both in the conversion and refurbishment of existing buildings and in new build constructions. Promat TL Board® panels can be fitted direct to the underside of a floor or to a supporting framework where the surface is uneven or otherwise unsuitable...
