Powerdeck B is a high performance rigid polyisocyanurate (PIR) foam board for use in warm flat roofs under under torch-on, bituminous waterproofing systems.
Powerdeck B is a closed cell, CFC and HCFC-free (zero ozone depletion), rigid polyisocyanurate foam core faced, with a mineral coated glass fleece on the reverse side and a bituminous glass fleece with a sacrificial polypropylene film on the top surface. It has an exceptionally low thermal conductivity of 0.026 W/mK.
Powerdeck B, is available in a wide range of thicknesses, and will assist in meeting the appropriate Building Regulation standard with any form of warm flat roof construction.
Outstanding product quality manufactured to ISO 9001 Quality Systems.
Zero ozone depletion potential.
Low thermal conductivity.
The declared thermal conductivity value of 0.026 W/mK is some 30% more efficient than most other insulation materials
It is possible to meet the Building Regulation requirement with only 130mm Powerdeck B.
Fully compatible with torch-on, bituminous waterproofing systems.
Warm roof construction.
No requirement for roof ventilation and inherently safe from harmful interstitial condensation.
Powerdeck B boards are available in a tapered format to assist roof drainage.
Reduced risk of condensation.
Condensation within the roof structure is avoided as it is maintained at the same temperature as the inside of the building.
Powerdeck B is lightweight yet tough and resilient. It is easily cut using a knife or fine-toothed saw.
Powerdeck B is rot-proof, durable and maintenance free.
