Closed Cell Cavity Wall Insulation

We are affordable green builders and stopped using open cell foam as cavity insulation the day we finished our very first home with the product.

Closed cell cavity wall insulation.

We use technitherm closed cell for cavity wall insulation which is the market leading certified spray foam insulation suitable for new and existing cavity walls of all types. The cavity wall insulation and stabilisation system is an injected polyurethane foam product. This is a very interesting analysis on the benefits of open cell foam v. Technitherm is a closed cell polyurethane cavity wall insulation foam which is injected into the cavity of the property.

Cavity wall insulation overview. We can install cavity wall insulation within half a day. The benefits of closed cell foam insulation. Closed cell foam is very versatile and can be used to insulate a number of different property types.

Once the cavity is full the drill holes filled matching the existing wall. Closed cell on a cost basis. Closed cell foam insulation can be used in both the roof and the cavity wall of a domestic property as well as being used in commercial and industrial buildings such as offices or warehouse. Technitherm closed cell full fill cavity wall insulation is a market leading certified foam insulation suitable for new and existing cavity walls of all types either fully clear cavities or partially filled cavities with board insulation.

Cavity wall insulation foam is a closed cell rigid polyurethane foam formulated for injection into cavity walls. The results that can be achieved will vary depending on the material used but calculations based on the use of walltite cv 100 rigid closed cell foam insulation injected into a 40mm cavity suggest that the u value of the refurbished wall should be in the region of 0 46w m2k to 0 56w m2k depending on the make up of the internal and external. Closed cell foam is the best choice for robust insulating where space is an issue as it can achieve 2x the r value of open cell inside a standard wall. Its closed cell properties mean that it is suitable for many different types of domestic and commercial properties including some previously thought to be unsuitable for cavity wall insulation.

Its rigid nature also adds to the structural integrity of the building and e84 fire rated versions are available. Isothane s foam cavity wall insulation technitherm has a proven track record of providing structural stabilisation and thermal insulation benefits to both domestic and commercial properties across the united kingdom for over 25 years. The trimmed out overspray filled an entire 10 yard dumpster. Because the foam is closed cell it means we can install it in any exposure zone even in areas at risk of flooding.

Our engineers drill 2cm holes in your outer wall then inject your wall with thermal bead cavity wall insulation.
