How to tell if you could get cavity wall insulation installed in your home

Cavity wall insulation is one of the most in demand home improvement measures on the market. Not only does it keep your home warmer, it also reduces your energy bills by keeping the heat in the house and makes your home more energy efficient. If you don’t know whether or not your home has insulation installed, follow this handy guide to work out how you can check.

What are Cavity Walls?

Cavity walls are constructed with two walls that make up a single wall that have a hollow space between them. The two walls are called the leaves of the cavity, with the internal wall being the internal leaf and the external wall being the external leaf.

Is my wall a cavity wall?

Any home built after 1920 was more than likely built with cavity walls. You can tell whether or not a wall is a cavity wall by looking at the brick work on the exterior leaf. A cavity wall usually has a regular brick pattern. If your wall has been covered by render, you can also tell by measuring the width of the wall. Use a door or a window to measure the distance between the outside wall and the inside wall. If this is more than 260mm thick, it’s probably a cavity wall. Anything thinner than that is likely a solid wall.

Can I get cavity wall insulation?

Most homes that have cavity walls are eligible for insulation. If your home was built within the last two decades, you probably had cavity wall insulation installed when the house was built. As long as the wall cavity is at least 50mm wide, you can have insulation installed in your home. Both of the leaves also need to be in good condition before an installation can take place.

How can I know if I have insulation already?

There are several really easy ways to determine whether or not you already have cavity wall insulation installed in your home. Firstly, your EPC rating will be high (between A and C) if you have insulation installed. If you have draughts in your house, it’s worth looking for the cause of them. If they come from the walls, it’s a sign that you don’t have cavity wall insulation fitted.

If you can get access to your loft, go up and check for insulation and measure how thick it is. If your loft has no insulation, it’s pretty safe to assume your cavity walls don’t. If it’s thin, the insulation in your walls is probably thin. Either way, it’s time to look for cavity wall insulation near me.

Installing cavity wall insulation is not a job you can DIY, no matter how skilled you are. If you need insulation installed in your home, be sure to call a professional to carry out the procedure. You will certainly reep the benefits of a warmer home and lower energy bills within weeks, and the initial cost of the installation will pay for itself in bills savings within two years.
