The warm deck roof design is the modern method for flat roof construction and is preferred wherever this option is possible.
So called because the insulating layer is located above the roof rafters and between the structural supports, a warm deck roof results in a temperature for the roof and loft area that is consistent with the rest of the property.
Previously, the cold deck method of flat roof construction was favoured. However, with changes in how people live and how properties are utilised, this has now changed.
To construct a mechanically fixed warm deck using EPDM, you will require: - Roof deck - minimum 18mm ply or OSB3 (Oriented Strand Board) deck - New vapour barrier (or leave the existing felt membrane in-situ if this has not suffered water damage) - Kingspan TR26 foil backed insulation, or similar - 9mm / 11mm ply or OSB3 board To do this, you will need to: - Overboard the insulation with a 9mm / 11mm ply or OSB3 board - Screw the 9mm board and insulation down into the existing roof joists - Install EPDM rubber roof as per installation instructions
