Is External Wall Insulation Worth It?
EWI Installer Providing All Aspects Of Exterior Insulation
We are often asked whether or not getting external wall insulation installed is worth it in terms of return on investment. We believe it is! As you can see from the house diagram up to 33% of heat is lost through the walls of our home. This causes a constant chill which leads people to switch the heating up full which costs a significant amount of money.
When you heat a cold room with freezing walls it forms condensation on the exterior wall. The same thing happens to your windows. The warm air hits the cold walls which creates moisture. As a consequence, due to the constant cooling and heating, moisture builds up producing mould and damp, which can lead to high potential repair costs.
External walls are cold because they are the only barrier between the room and outside and typically have no cavity. External wall insulation is easier to install compared to internal wall insulation because it involves the hassle of removing skirting boards, carpets/flooring, plastering boarding, painting and decorating, removing radiators, etc.
External Wall Insulation Prices
There are several factors that will determine your external wall insulation quote. For example, whether you have solid walls, the type of insulation components required, how much scaffolding is needed, what rendering finish you choose (silicone or monocouche), etc, etc.
Approximately you can expect a professional and fully trained EWI specialist to charge between £150 to £200 per m2 (including labour and materials). You DO NOT want to go cheap on exterior insulation because a poorly installed system will lead to you having to pay even more to fix it, ripping off the old and starting again, further down the line.
It is worth considering other potential costs including scaffolding and alterations to window sills, guttering and down pipes and verge trims to accommodate the additional 90-120mm for the render.
