Cavity wall insulation involves the injection of a suitable insulant using a specified and approved system designed to ensure a complete fill of the cavity wall area.

Cavity wall insulation foam injection.

This process creates holes in your walls that need to be filled patched and painted. What is cavity wall insulation. 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. Very similar to expanding builders foam in nature this form of insulation is again pumped into a cavity via a pressurised pumping system but unlike the below method the holes required to pump into the cavity can be much smaller making it a much better solution for properties constructed from engineered bricks as.

Injected pu foam is a two component chemically modified polyurethane foam which achieves superior u value and air permeability results. Cavity fill is a medium density 2 0 lb ft injection foam insulation kit that cures to fairly rigid in about 1 hour. They are injection foam and spray foam and each has its specific applications. Technitherm is a closed cell polyurethane cavity wall insulation foam which is injected into the cavity of the property.

This foam material flows throughout the wall cavity compressing and engulfing the old material filling up your wall. A slower curing time allows the foam to flow into smaller crevices and reach into more places. 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. Expanding foam insulation has increased in popularity as the manufacturers have praised its uses and abilities and its applications have reached to include cavity walls.

Yes you can use expanding foam insulation in cavity walls. This insulation is able to do what no other product can.

Injection foam expands to work into difficult areas that blown in insulation may ignore. The injection foam can be used to re insulate older homes that contain little or no insulation even if the wall cavity is partially filled with old ineffective insulation.

Foam insulation is probably the best retrofit choice in terms of avoiding wall damage.
