How is External Wall Insulation Installed?
External Wall Insulation, otherwise known as External Façade Improvement (EFI) is the process of insulating your home by installing a layer of wall insulation material which is fixed to the exterior wall which is designed to protect and insulate. This layer is then covered with reinforcement and a special type of render, then completed to a high standard with a finish of your choice.
Choosing your External Wall Insulation finish is important to make sure you get the perfect look for your home. To help you decide, Nesture has an external wall insulation tool, to show you what your home will look like once the project is complete. You can choose from a variety of finishes for an attractive finish including render, pebble dash, brick slip or brick effect render.
External Wall Insulation has several benefits; however, it can change the external appearance of your home. If you are unsure then it is best to check with your local planning authority whether you will need planning permission, our customer support team can also provide help and advice.
The most common restrictions for External Wall Insulation are on listed buildings or if your home is in an area of conservation. If you want to install External Wall Insulation to more than 25% of your walls, then you will need to make sure they are up to current standards. This will aid the installation process. You must also ensure that the thermal performance of the insulated wall has a U-value of no more than 0.30.
