The Best Cavity Wall Insulation

About Icynene

Cavity walls were standard in houses built between the 1920s and 1980s.  The motivation behind an additional wall was to prevent an ingress of water or drafts into the home.

On the contrary, what this design led to is more problems as it created a home for mould and condensation to form, which in turn impacted walls inside the home. In addition, drafts caused by air leaks are common. For homeowners who are now trying to rectify problems such as these, it can be costly as a result of the building work required to access the cavity space and fill the gap with cavity wall insulation.

Luckily for homeowners and cavity wall insulation installers, there are a few options available:

1. Spray foam insulation
2. Mineral wool
3. Beads and granules

Out of these, we recommend choosing spray foam for cavity wall insulation for 3 reasons:

• The dry wall doesn’t need to come down

As it can be blown into the wall from a hole, spray foam insulation is becoming an increasingly popular choice for both cavity wall insulation installers and homeowners. As the dry wall can stay in place for the work, this means that cavity wall insulation isn’t a messy, excessively time-consuming (cost-consuming for the customer) project.

• It fills every gap and air leak

When sprayed, Icynene spray foam is a liquid that quickly fills every gap. Upon contact with the air, spray foam starts to solidify and expand, providing a complete air barrier that has a high R-value. As no crevices are left clear, air leaks and eliminated, resulting in savings of up to 90% of energy bills.

• Spray foam cavity wall insulation has the best thermal properties

Regarding thermal properties, Icynene® spray foam insulation is the best cavity wall insulation. Due to the air barrier, homes retain heat during colder months and prevent heat from infiltrating the walls during hot summer months. A steady temperature is maintained for a comfortable living space.
