Why should you Insulate your Cavity Wall?

If your home experiences cold winters, high energy bills and is subject to loud noises, then you could be looking at a simple and easy fix, cavity wall insulation. Insulating cavity walls is one of the most effective ways to curb excessive noise and provide that much needed warmth throughout the winter months. External walls of a home experience one of the highest (if not the highest) percentage of heat loss, averaging up to 35% of heat loss. Therefore, by installing a sufficient insulant to reduce this percentage, your home will be better off for it. Whether you live in London, Manchester or anywhere else across England, you should make sure you prepare for those harsh winter months with a sustainable and effective home insulation solution.

What is a Cavity Wall?

You may not have come across this term before, you think of a home and just know it has walls, interior and exterior. However, most homes post-1920 have been fitted with a different type of external wall, a cavity wall. A cavity wall is simply a wall in your property that has a gap in between another wall. If your external walls are separated by spacing in between and another wall, then you have got yourself a cavity wall. Traditional singular external walls have become outdated and inefficient due to their inability to sufficiently insulate.
