What is Cavity Wall Insulation (or)?

Cavity wall insulation is a great way of increasing the thermal efficiency in homes with cavity walls. Let’s first understand what a cavity looks like.

Cavity walls are made up of two walls with a gap between them. Cavity walls can be found in any UK home built after 1920. It is possible that your home was not built within the last twenty years.

Let’s now get to the meat of the matter. Cavity wall insulation refers to the process of filling walls using mineral wool or polystyrene bead. This is done on the outside of the walls. This acts as an insulation barrier and prevents hot air from escaping. This will allow your home to remain warm for longer.

Un-insulated walls account for a third of heat loss from a house. Insulated cavity walls are a solution to this problem. Insulated cavity walls will help to keep heating costs low and the environment safe.

Cavity Wall Insulation Grants- Benefits

In case you’re wondering, here are some benefits to applying for cavity wall insulation grants.

Low initial costs

Even though the initial cost of installing cavity wall insulation was prohibitive, grants for home insulation are available to help reduce that cost or to get your home completely insulated for free if you’re low-income.

Reduction in energy bill

Home insulation grants are offered by the UK government to make insulation more affordable. This reduces heating costs as inefficient insulation results in 35% heat loss per house (on average).

Professional work

The greatest benefit of this grant for cavity wall insulation grants is that it is performed only by qualified professionals chosen by the government. This ensures that you will receive excellent work with few flaws.

  • * Steel- or timber-framed construction are not allowed in any area.

Types of Cavity Wall Insulation

These are the main uses and types of cavity wall insulation.

Polyurethane Foam (PUR).

PUR is a fluid-like substance which provides seamless insulation and thermal bridges. It expands when injected into a cavity. PUR insulation is the most economical, but it’s also the most costly.

Polystyrene beads/granules

The insulation material can be purchased loosely or with a light-colored sticky resin to hold the beads together. The cavity is blown using compressed air. Although polystyrene beads are more affordable than the other options, they’re not as efficient.

This insulation option is most eco-friendly. This insulation is made from fibreglass flakes and has a low environmental impact. You can blow the cavity with compressed air, using blasted mineral fibers such as polystyrene beads.

Cavity Wall Insulation Grants

Insulation can reduce your energy bills. But not everyone can afford to pay for the installation.

If you are, you’ll be happy to know that you can insulate your cavities walls with minimal expense. Yes, that’s right. Two grants have been provided by the government to homeowners in the UK for cavity wall insulation.
