Application

For flat roofs under built-up felt, mastic asphalt and single-ply membrane waterproofing systems. 

Description

Powerdeck® F is a high performance rigid polyisocyanurate (PIR) foam board for use in warm flat roofs under built-up felt, mastic asphalt and approved single ply membrane waterproofing systems. It is faced both sides with a mineral coated glass tissue.


Mastic asphalt waterproofing

An isolating layer of Type 4A sheathing felt must always be used in mastic asphalt waterproofing systems. This isolates the asphalt from movement in the substrate, allows the lateral movement of moisture vapour and warm air during installation of the asphalt and acts as a vapour pressure release in service.


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® F 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 to help resist wind uplift. Calculations relating to the bonding and any supplementary fixings should be made with reference to BS 6399.


Features and benefits:

  • Manufactured to ISO 9001 Quality and ISO 14001 Environmental Management Systems.
  • Manufactured using a blowing agent with zero ozone depletion potential (ODP) and low global warming potential (GWP).
  • Thermal conductivity as low as 0.024 W/m·K (depending on thickness).
  • Available in tapered format to assist roof drainage.
  • No requirement for roof ventilation and condensation within the roof is avoided as the structure is maintained at the internal temperature.
  • CE marked in accordance with harmonized European standard EN 13165.

Fire performance

When tested to BS 476-3:2004, the product achieves an FAA rating when waterproofed with a 3-layer built-up felt covered with 10mm chippings. For other specifications it is advised to contact the manufacturer of the cap sheet for fire classification details. For single ply membranes, the rating achieved will vary depending on the single ply membrane used.
