Cold Deck Flat Roof Construction, Repair and Replacement
COLD DECK FLAT ROOF CONSTRUCTION
REPAIR AND REPLACEMENT WITH AN EPDM RUBBER ROOFING MEMBRANE
Less thermally efficient than a warm roof construction, cold roof construction remains the most common form of construction for existing flat roofs. A cold deck is constructed as follows:
The insulation material is placed immediately above the ceiling between the rafters.
The 18mm roof-grade deck is then fixed on top of the rafters, leaving suitable airflow between the insulation and the deck. The sheet is then installed using the water-based deck adhesive onto the deck.
This is known as a cold roof because the roof deck and roof space are close to the external air temperature. This means the void below the roof deck must be well-ventilated to avoid condensation.
Our membrane is the perfect material to finish off a cold deck design. It is highly resistant to punctures, tearing, and splits, doesn’t rot and will last for more than 50 years.
If you’re working on a cold deck design for your roof, make the sensible choice and choose a FlexiProof membrane as the final layer.
