Reasons why these three materials are best for cavity wall insulation

Most cavity walls can be filled with particular materials to provide insulation and retain heat in your building. Pretty much every home built after the 1930s will have cavity walls and unless your house has been built within the last 20 or so years, it is more than likely that your cavity walls are empty and could do with some wall insulation.

Cavity wall insulation is not a simple process, though it is simple when you choose a trusted insulation team to help you out, but choosing which material isn’t so simple. In this guide, we will explain three materials and why each of them is best for cavity wall insulation. And if you require this solution, just search ‘cavity wall insulation near me’ in your search engine for the best results.

Foam insulation

The best and most highly regarded thermal cavity wall insulation material is foam insulation, which is made primarily of polyurethane. That said, installing foam cavity wall insulation can be difficult, so you must have an insulation specialist come and carry out the entire insulation process for you.

Spray foam insulation is among the best methods of cavity wall insulation available today. The process consists of having small entrance holes drilled into the outside of your home, where spray foam is then sprayed as a liquid state into the voids between both walls. The liquid then expands to 100 times its original size, transforming into foam.

Mineral wools and fibres

Mineral wool is a material that is used quite often in cavity wall insulation. Mineral wool and fibres are made up of strands of fibreglass or wool that are compressed and forced into the cavity.

Mineral wool is great for cavity wall insulation since it can be filled and packed tightly and is really easy to be slid between joints. This is an effective material for cavity wall insulation because it is water-resistant and prevents rainwater and moisture from passing through the outer leaf of the wall and into the building’s interior.

Beads and granules

Beads, which are usually polystyrene, can either be applied separately or with a mild adhesive to keep them together intact. Because of their rough shape, granules will naturally stick together. Both beads and granules are blasted into the wall cavity using compressed air, similar to mineral wool.

Polystyrene is most commonly used as the material for beads and granules, making them an ideal cavity insulation choice for individuals who desire a cheaper and more cost-effective alternative. Since beads and granules are engineered to trap and retain heat efficiently, they’re a popular solution and a great material. Another reason why this material is great for cavity wall insulation is that it can be used to build a wall insulation style that has no gaps.

Cavity wall insulation for you

This type of insulation is far cheaper than external wall insulation. If you’re considering this insulation solution, it should be carried out by a professional insulation contractor who is qualified to do so.
