Warm Roof Cold Roof Hybrid

Combining elements of both cold and warm flat roof design hybrid roofs appear to offer the best of both worlds when it comes to maximising thermal performance while limiting constructional depth.

Xtratherm manufactures an extensive range of high performance pir flat roof insulation boards that include tapered insulation providing comprehensive technically advanced solutions for all. If the basic warm roof construction is followed before extra insulation is installed problems can arise. The object being to design out the possibility of warm moisture laden air coming into contact with a cold surface and condensing. Flat roofing solutions the xtratherm range of high performance insulation boards provides the ideal technically advanced solution for flat roof projects.

Warm roof insulation ensures the entire roof structure is insulated meaning a warm deck roof is more energy efficient than a cold roof. This solid tiled and insulated roof is designed to keep you warm in winter and cool in summer for all year round comfort. There are three recognised designs of flat roof construction. In a warm roof construction the principal thermal insulation layer is located above the structural decking resulting in the structural deck and support structure being at a temperature close to that of the interior of the building.

The warmroof hybrid is our luxurious solid tiled conservatory roof built with slimline glass panels to let the light into your room. But as daniel bosworth design technical manager at sig design technology explains they should be approached with caution. A cold flat roof insulation requires more work taking off old boards and replacing them and the roof surface. Warm roof construction requires that the entire roof construction is encapsulated within the insulation envelope of the building to be kept warm.

Warm cold and inverted. Unfortunately you appear to be describing a hybrid roof which is a form of construction that increases the risk of condensation. When issues like those above occur it s not surprising that people look at the space between the joists and wonder if they can use it for more insulation. We would recommend either a fully warm roof with insulation on top of the roof deck or a cold roof with a minimum 50mm well ventilated cavity between the roof deck and the top of the insulation.
