We all want to save money on our energy bills, and to make sure the money we spend on heating isn’t going to waste. Draught-proofing can have some impact, but it is too focused and cost benefits can be quite hard to realise. The bottom line is that prevention is better than cure!
What about loft insulation?
Many people think loft insulation is the best way to keep heat in the home. It’s certainly true that it can be a cost-effective way to insulate. However, what it fails to address is that most thermal energy is lost through the walls of a properly – roughly 35-40% in fact. With uninsulated walls, there is little slowing the movement of heat to outside.
How does external wall insulation work?
Both solid walls and cavity walls can be insulated externally. This involves installing an insulating material and rendering over the top. It’s not cheap, but it is an effective and long-lasting way to insulate your home. With external wall insulation installed, walls store warmth and slowly release it back into the home. 90mm of EPS attached to a traditional 9-inch solid brick, will reduce the U-value (which is a measure of how much energy is lost) from 2.2 down to just 0.3 per m2K, bringing it in line with a brand new wall built today.
Other benefits of external wall insulation
External wall insulation has other benefits. It will smarten up the outside of your home, and optional brick slips can recreate a traditional look. It will also help muffle noise entering the home and prevent penetrating damp. You won’t lose floor space and it can be done with minimal disturbance to the household.
So there you have it: reduce energy bills by up to 40% and benefit from a warmer, more comfortable living environment!
