Dunster House roof insulation is made by bonding together an MFP board and 50mm polyurethane insulation. The MFP board acts as a top layer, between the insulation and the chosen roofing material.
Looking at the image you can see how the roof of one of our log cabins is made up. First the 19mm Tongue and Groove roof boards, then the polyurethane /MFP goes on top. The MFP board is then covered by the roofing material, in this case shingles, giving your log cabin a roof thickness of approximately 80mm.
As our roof boards are 19mm thick, you can screw through the insulation sheet where ever you please, without having to locate a purlin. From inside the log cabin you will see attractive Tongue & Groove roof boards, the roof insulation fits on top of the roof boards and is not visible, therefore not spoiling the overall appearance of your cabin.
This quick and convenient method allows for speedy installation.
