Installing External Wall Insulation

By

 

External wall insulation is essentially a layer of protection for your property, which has multiple benefits. Such as the property retains much more heat on the inside, therefore feeling a lot more comfortable. In addition, the heating system should work less hard, helping save money off heating bills.



External wall insulation (EWI) is the preferred choice to upgrade the thermal efficiency of properties with solid walls, made using a single layer of bricks. Most UK houses built before 1930 have solid walls and EWI is the ideal option if there are no restrictions on the property. Uninsulated walls allow around a third of the warmth in a house to get out. Making your central heating system work harder to maintain the desired temperature. External and cavity wall insulation will help to keep heating costs low because your boiler won’t work as hard wasting energy to keep the ideal environment.



Benefits

Installing EWI doesn’t interrupt the residents within the property you’re in the way that internal insulation would, so you can comfortably live in the house during the Installation period. It can also help to improve weatherproofing and sound resistance. Adding external wall insulation also can be used as a good opportunity to update the appearance of your home. You could make it look how it was previously or make some changes and improvements to increase your house’s kerb appeal, increasing its value.


How to Install EWL

  • Work out your wall type

While external wall insulation can be suitable for a range of properties, it’s most commonly applied to homes with solid brick walls. It can be tricky to tell the makeup of your home’s walls, but there are some clues to look for. Alternating brick patterns tend to be solid walls. The age of the property will also give indications. 

  • Find an installer

Make sure your installer has credentials and can show you examples of their previous work or ask around to find a trusted installer recommended by others.

  •  Have a survey

Your qualified installer will assess your walls to identify what insulation is best allowing you to calculate costs. 

  • Get your external wall insulation installed

As the insulation is being applied to the outside of your property, you won’t need to leave the property while work is being carried out. Scaffolding will be erected, and you can expect some noise while walls are being prepared and the insulation is fixed. But disruption should be minimal.

  • Render or cladding 

Your external wall insulation will be finished with either render or a cladding system. Installing EWI, including insulation and finish, typically takes around three to six weeks.



What maintenance is required for external wall insulation?

Good general property maintenance is important. Make sure that any issues you notice, such as cracks in the render, broken seals around windows are resolved swiftly. This will protect the insulation against water ingress and preserve its performance. EWI have a long lasting effect with little to no maintenance needed for at least a period of 40 years, but we still advise you to check once in a while.

  One of the more common complaints about houses with poor build quality is noise transfer, both from outside sources but in particular between the rooms in the house itself. Poor acoustics is something that could, and should, be considered at the design stage of a project. Sound transmission between homes, is a major problem in the UK which requires serious consideration from both architects and builders. Noise nuisance can be a serious cause of stress, and if not remedied it can affect our health and wellbeing as well as influencing everyday life.   What Does Soundproofing Do? To soundproof a home means to lower the intrusion of external noise, while also insulating it so noise cannot escape the space. In many cases acoustic insulation is used to prevent any noise from outside interfering with the residents within. This could be anything from voices, nearby building works or high lev...
