Rigid PIR insulation for warm flat roofs under torch-on waterproofing systems.
For use in warm flat roofs under bituminous torch-on waterproofing systems.
Powerdeck® U is a high performance rigid polyisocyanurate (PIR) foam board for use in warm flat roofs under bituminous torch-on waterproofing systems. It is faced with a bitumen glass fleece on both sides.
Roof drainage
To ensure adequate drainage the roof should have a minimum finished fall of 1:80. This may mean designing for twice the minimum finished fall to account for building inaccuracies, roof deflection and building settlement. Powerdeck® U boards are also available for tapered insulation schemes.
Thermal bridging
With increasing levels of insulation it is important to ensure the continuity of insulation at the junction of elements.
Wind uplift
The wind uplift force exerted on the roof will vary according to geographical location, site location and building height. Reference should be made to BS 6229 for adequate bonding of the vapour control layer to the deck. Calculations relating to the bonding of the insulation and any supplementary fixings should be made with reference to BS 6399.
