SOLID WALL INSULATION
Click here if you are not sure what type of walls you have or if they are already insulated.
Solid Wall Insulation is typically installed in properties that do not have Cavity Walls and are therefore classed as hard-to treat. These include stone, concrete and pre-1924 brick-built homes.
If your property has Cavity Walls, the easiest and cheapest method of insulating them is to fill the cavity with an insulating material. Most properties built after 1982 had the cavity filled at the time of build. Prior to 1924, brick-built properties tended to be of solid construction.
The diagram below shows how to tell the difference between a brick-built Cavity Wall and a Solid Wall. Cavity walls do not have square brick ends showing and they are generally thicker than solid walls. A cavity wall will be at least 10 inches thick whereas solid walls are normally less than 10 inches thick. This can be measured around your window or door openings.
Up to 45% of the heat lost in your home can be prevented by installing Solid Wall Insulation. There are two main types of Solid Wall Insulation to consider: External Wall or Internal Wall.
External Wall Insulation
Applying insulation to the exterior wall surface is currently the most popular form of Solid Wall Insulation. An insulating material is fixed to the outside walls and either render or cladding (including brick or stone tiles) is applied to form a decorative finish.
As the exterior appearance of the property will be changed, it is essential to check with your local Council whether planning permission is required before going ahead with this type of Solid Wall Insulation. Our approved installers can help you with this.
A grant of up to 25% is available for External Wall Insulation and we can organise a free survey and quotation.
Please see our External Wall Insulation page, for more information
Internal Wall Insulation
Solid Wall Insulation can be applied to the internal surface of the walls using either stud walls or insulation boards. Stud walls tend to be stronger and can hold the weight of cupboards etc. but they are generally thicker than insulation boards. This type of insulation is less popular than External Wall because it is more disruptive and there are generally more fitting & fixtures to move.
We cannot help with grants to install this form of Solid Wall Insulation to the inside of your home but we may be able to assist at a later date.
Please see our Internal Wall Insulation page for more details.
Cavity Wall Insulation
Your home will not require Solid Wall Insulation if it has a Cavity or air gap between the two layers of brickwork. Properties built of brick between 1924 and 1982 were typically of Cavity Wall construction and this gap was not filled when the property was built.
Cavity Wall Insulation is the simplest and most effective way of insulating the walls of your home. 100% grants are currently available to all private households.
Please see our Cavity Wall Insulation page for more information.
100% grants are subject to a free, no-obligation survey. In most cases it is free but you may be
asked to pay a contribution, depending on the efficiency of the property and the amount of work required.
