What Is Cavity Wall Insulation?

This is a type of insulation that will go in this space between walls. Blown into the wall cavity, it quickly fills the space creating a barrier designed to prevent heat transfe. Wall Insulation can reduce heating costs and helps to stabalise the overall temperature of your home, making it comfortable to live in all year round.

Frequently Asked Questions

What is blown insulation?
A blown-in system is a process to install insulation. It’s extremely quick and pumps the insulation into spaces to ensure that they’re well filled at the right density to work at the optimum performance.
Why is wall insulation important?
External walls account for up to 35% of heat less from the average house. With an uninsulated cavity, heat can easily escape meaning it requires more energy to maintain a comfortable temperature. A wall cavity filled with insulation can help reduces this heat loss, making the house warmer and reduce or in some cases remove the need to use heaters and fireplaces to heat your premises.
How can you insulate existing walls?
Cavity wall insulation (cwi) is installed by professionals usually from the outside by drilling small holes in the wall and injecting loose insulating particles which settle to fill the cavity in your wall. Once complete, the drilled holes are filled again with minimal change to the aesthetics of the wall. A three-bedroom, semi detached home can be insulated in less than three hours by a trained installer.
