How much insulation do I need in my walls? If you’re asking yourself this question, then chances are, you’re talking about your cavity walls.
Solid walls do not have a gap between two layers of brickwork, so there is no space for you to insert any material ‘in your walls’.
A cavity wall does contain this gap, which many people like to fill with some form of insulating material in order to boost the thermal qualities of their home.
This process is completed by drilling strategically-placed holes into your exterior walls. A series of hoses are then placed into the holes, and an insulating foam material is sprayed into the gap.
As you can’t see this process taking place behind the brickwork, it is very much a guessing game of how much is required, and if you’ve adequately covered your wall space.
The Best Time to Insulate
For this very reason, it is a lot more effective and a lot cheaper to have wall insulation installed at the very beginning of a building project.
Unsurprisingly, it is a great deal more complicated adding insulation material afterwards, once the building is fully erect.
However, we do realise that not everyone has this luxury, and you more than likely live in a house you didn’t build yourself.
So with this in mind, let’s move on to measurements, and why they matter….
