Eliminating old and weathered ventilation which brings with it the potential condensation risk related to giant voids of cool air makes the warm roofing system is the optimum roof resolution.
In a heat pitched roof construction the thermal Insulation is placed within the rafter line. The position of the insulation is usually often a lot higher than the rafter; however in warm roofing systems it is positioned between the rafters or partly between and below the rafter.
If the insulation thickness partly fills the rafter depth the vapour open / porous underlay ought to be draped over the rafter. The underlay must not be allowed to touch the surface of the insulation and a transparent air pocket is created between the membrane and insulation.
It is then secured by counter battens to permit water to empty effectively across the membrane surface and from the roof. To ensure a full watertight and insulated warm roofing system, all joints, fixings, overlaps and penetrations must be sealed using tape.
Here at Advanced Windows in Burnley we have over 20 years of experience in fitting the most modern roofing systems. A lot has changed over the years but the warm roofing system is the most modern and heat effective solution that has every been.
