Achieving a u value of 0 20w m meaning your roof will be better insulated than your walls will need 120mm thickness of rigid foam or 200mm of mineral wool or natural insulation. Tlx silver is a vapour barrier and this structure gives no risk of surface or interstitial condensation. This is called a warm roof as the majority of the insulation is above the timbers of the roof so the roofing timbers are insulated and therefore warm.

The traditional cold deck flat roof system is to install the insulation between and under the joists with ventilation below the timber deck.

The photos suggest 25mm of mineral fibre on the underside of the roof. They lose loads of heat and are prone to leaking causing the materials to deteriorate. In this video i look at how this has happened and the way to resolve t.
