What is cavity wall insulation and why do you need it installed in your home?

Cavity wall insulation is a type of insulation that is installed in the walls of your home. It helps to keep your home warm in the winter and cool in the summer and can also help to reduce your energy bills.

There are a number of reasons why you may need cavity wall insulation installed in your home. For example, if you live in an old house with uninsulated cavity walls heat will be escaping through the walls causing you to have higher energy bills than necessary. Cavity wall insulation can help to prevent this from happening.

Additionally, cavity wall insulation can also help to improve the overall energy efficiency of your home, make it more comfortable to live in, and can even help to protect your home from damp.

If you have decided to proceed with cavity wall insulation it is important to choose the right installer for the job. You need an installer who is registered with one of the major insulation industry bodies such as Kiwa, CIGA or NIA. You’ll also want to check that they have sufficient experience installing cavity wall insulation.

Is cavity wall insulation the best option for your home?

Before you progress with cavity wall insulation it is important to assess whether it is the right option for your home. Cavity wall insulation is best suited to homes that have an uninsulated cavity between the walls. If your home has insulated cavity walls it is worth checking if there is an existing guarantee and that the existing insulation is sufficient. If there isn’t sufficient insulation you might want to consider cavity wall extraction and cavity wall refill.

If you are unsure if cavity wall insulation is the best option for your home, speak to a registered installer who will be able to advise you.

Frequently asked questions about cavity wall insulation

How can I tell if my home has cavity walls?

Cavity Walls are likely to be your wall type if your home was built after 1930. If your home has cavity walls the external wall will have two masonry (brick or block) walls, with a cavity (an empty space) of at least 40mm between each wall. You can tell if your home has cavity walls by its brick pattern called ‘stretcher bond’ where the bricks are evenly spaced (solid walls usually have an uneven pattern).
