Cavity Wall Insulation

Cavity Wall Insulation

Free cavity wall insulation grants cover the cost of making a property well-insulated. This grant funding is a part of the ECO (Energy Company Obligation) Scheme, intended to make homes energy efficient and is backed by the government in the UK. These grants aim to make the properties well-insulated that are built between 1924 and 1982 and have a cavity between two brick layers or between brick and block.

During CWI (cavity wall insulation), insulation is inserted in the cavity present between two layers of bricks. Different types of materials can be utilised to insulate the cavity wall based on the type of cavity, such as polystyrene beads or granules, polyurethane foam, glass fibre, and mineral wool. This insulation helps reduce heat loss from walls, enhances thermal efficiency, reduces heat transfer outside the wall, and decreases overall carbon emissions.

Green Home Grants UK is a registered company providing services to help clients get cavity wall insulation grants via its team of specialists. Our experienced professionals help them reduce their energy bills, eliminate the loss of 35% heat from the property, and save significant money. In this way, we also ensure compliance with Building Regulations that require installing insulation in the cavity walls of buildings built before 2005.

Frequently Asked Questions

How long does it take to insulate a cavity wall?

Usually, it takes almost 2 to 3 hours to insulate a cavity wall in an average-sized property.

How can I identify if insulation is already in my property's cavity wall?

You can identify if your property’s cavity wall is insulated by inspecting the drilled holes under the windows to see if they are filled with cement. You can inspect the drilled holes where the mortar forms a T joint.

How to avail the cavity wall insulation grant if one lives in a flat?

It is required to install insulation in the cavity starting from the ground floor to the roof. Therefore, you need to get the consent of your neighbours living above and below your property before you apply for this grant.

What to do if there is dampness in my property’s walls?

If you want to avail cavity wall insulation grant, inspect the walls to identify the cause of dampness and repair it before submitting your application.

In what cases does cavity wall insulation require removal?

Cavity wall insulation removal is required if the previous insulation is installed incorrectly, leading to moisture build-up. Therefore, new insulation will help eliminate the dampness and vermin infestation problems.

What is the difference between cavity and solid walls?

Generally, two bricks wide, a solid wall incorporates bricks that interlock to form a solid 9-inch wall. With no gaps between the bricks, the insulation shall be done either inside of the building or externally. From looking at the structure, you will see a solid wall alternating between header and stretcher bricks. On the other hand, the exposed brickwork of a cavity wall will show all the bricks with the same length. They are also much wider (typically 270mm) than solid brick walls.

Thus, in cavity walls, bricks are laid lengthways in an even staggered pattern. On the other hand, in solid walls, bricks are laid both lengthways and across the wall width.
