Expert Insulation Contractors in Manchester

Our spray foam insulation provides far less fire risk than the wooden elements in the roof. The system has been tested to British Standards and certified as a Class 1 fire rating, meaning that the foam is effective in resisting the spread of flame.

After the installation of spray foam your roof is bonded together into a continuous structure, this greatly reduces the chance of tiles breaking from impact damage etc. However, should a tile break for any reason it can be removed and replaced in the future, it just takes more effort than normal. We recommend cutting out the foam from the area of the tile and removing the tile from the outside, after replacement the tile can be sprayed back in place with foam.

Spray foam insulation can offer virtually any insulation value required, simply by altering the depth of the foam you can achieve as little or as much insulation as you require. As a rough guide, foam insulation offers around twice the insulation values of mineral wool, a roof without felt can be insulated to current Building Regulations for loft conversions with around 100mm of foam insulation on the roof alone.

Spray foam insulation is not used as an internal waterproofing product on domestic roofs. When working on domestic roofs, our installers will carry out all necessary roof repairs before installing foam insulation, this allows us to guarantee the roof for 25 years against water ingress. Foam insulation is used to bond the roof after we have carried out any necessary repairs, our installers will make your roof waterproof before the foam is applied. When used externally on industrial buildings or similar, foam insulation can be used to waterproof a roof. This is only when the foam is applied externally and covered in a suitable coating, this is not recommended for domestic roofs.
