External Wall Insulation Grants: How To Qualify?

Did you know that 3 out of 5 UK homes have a low energy efficiency rating and that external wall insulation grants could help to address the balance? 

If your home was built before 1920 it is likely that your property has solid walls – either solid brick or solid stone. Most buildings built after 1920 are of cavity wall construction). If your house has solid walls then it may benefit from having external insulation installed, which can help to substantially reduce heat loss and also to help prevent dampness from penetrating through the walls.

In this article, we’ll explore everything you need to know about external wall insulation, or EWI for short, the difference it can make to your comfort and energy costs, and how to get this effective energy improvement for free. 

Why is External Wall Insulation Important For UK Homes? 

External Wall Insulation (EWI) is a highly effective solution for homeowners in the UK seeking to enhance the comfort, energy efficiency, and overall quality of their homes. 

From providing year-round comfort to contributing to cost savings and environmental sustainability, EWI is a wise investment that goes well beyond its initial installation.

External wall insulation grants are available throughout England, Scotland and Wales to help homeowners make their homes more efficient and bring down energy costs. 

If you receive benefits or your home has a low energy performance rating, you may automatically qualify for free improvements. 

How Does External Wall Insulation Work? 

External Wall Insulation (EWI) is a construction technique used to improve the thermal performance and energy efficiency of buildings while enhancing their appearance. 

Here’s how EWI works:

Preparation: The first step is to prepare the external walls of the building. This typically involves cleaning the walls and repairing any existing damage, such as cracks or gaps.

Insulation Layer: A layer of insulation material is then applied directly to the external walls. This insulation layer can vary in thickness depending on the desired level of thermal performance. Common insulation materials include expanded polystyrene (EPS) and mineral wool.

Mechanical Fixings: The insulation layer is securely attached to the walls using mechanical fixings, such as plastic dowels or adhesives. These fixings ensure that the insulation remains in place and does not detach from the walls.

Reinforcement: A layer of reinforcement mesh is applied over the insulation. This mesh provides additional strength and stability to the system.

Base Coat: A base coat of render, often made of cement or polymer-modified materials, is applied to the reinforcement mesh. This base coat serves as a protective layer and helps to create a smooth and even surface.

Top Coat: Finally, a top coat of render is applied over the base coat. This top coat can be customized in terms of colour and finish, allowing for a wide range of aesthetic options. It also provides weather resistance and durability.

The EWI system effectively wraps the building in a thermally insulating layer, preventing heat loss through the walls and reducing the need for heating or cooling. 

It also helps to protect the building from weather damage and can enhance its appearance. EWI is a proven method for increasing energy efficiency and thermal comfort in both residential and commercial buildings.

The Many Benefits of External Wall Insulation For UK Homeowners

External Wall Insulation (EWI) offers a range of benefits for UK homes. Here are some of the key advantages:
