External Wall Insulation FAQ's
External wall insulation is a type of insulation that is installed on the outside of a building. It involves fixing insulation boards to the external walls of a building, followed by a render or cladding system to protect the insulation and provide a finished look.
External wall insulation can help to reduce heat loss from a building, resulting in lower energy bills and improved energy efficiency. It can also help to improve the appearance of a building, reduce condensation and damp, and improve sound insulation.
External wall insulation is suitable for most types of buildings, including houses, flats, and commercial properties. It is particularly useful for buildings that are difficult to insulate internally, such as those with solid walls or where space is limited.
External wall insulation is typically installed in several stages. First, any existing render or cladding is removed, and the walls are cleaned and prepared. Insulation boards are then fixed to the walls, followed by a basecoat and a topcoat of render or a cladding system.
The cost of external wall insulation depends on a range of factors, including the size of the building, the type of insulation used, and the complexity of the installation. However, it is typically more expensive than internal wall insulation.
It is possible to install external wall insulation yourself, but it is a complex and specialist job that requires experience and expertise. It is recommended that you hire a professional installer to ensure that the insulation is installed correctly and safely.
The lifespan of external wall insulation depends on a range of factors, including the quality of the installation and the materials used. However, external wall insulation can last for up to 25 years or more with proper maintenance.
Yes, there are a range of grants and funding options available for external wall insulation, particularly for those on low incomes or living in certain areas. It is worth checking with your local council or energy supplier to see if you are eligible for any funding.
