A retrofit often provides an opportunity to add insulation between the old roof and the new metal panels or to use insulated metal panels for the retrofit. Concrete flat roof insulation prevention of condensation. This is then covered with a further weatherproofing layer.

Either solution can have significant energy benefits. Types of flat roof. Our insulation for existing flat roofs is ideal for extensions dormer roofs and includes a layer of either 25 50 75 or 100mm insulation board. Remove the existing roofing membrane and inspect the roof for any deficiencies.

The waterproof covering is above the insulation and the vapour control layer is placed below the. I m wondering if there are any effective solutions that don t rely on closed cell foam.

A proper understanding of the link between thermal performance air leakage and condensation. It needs to be furred out with something so the trim details will later match. I d like to add insulation to this truss space.
