If you’re wondering whether your house has solid walls or not, there are a few ways to find out. One method is to measure the thickness of your walls. Here are a few steps to follow:
Take a tape measure near a window or door.
Measure the distance between the interior and exterior walls.
If the measurement is greater than 260mm, it’s likely that you have a cavity wall.
If the measurement is less than 260mm, it’s probable that you have solid walls.
It’s essential to know whether your walls are solid or cavity because insulation requirements differ between the two. Regardless of wall type, you can still make a few simple changes to keep your home warmer. For example, consider adding draft excluders to your doors and windows and insulating your attic and floors. These simple modifications can make a significant difference to your energy bills.
