What is wall insulation?
Wall insulation is designed to minimise the transfer of heat through the walls of your home. It does this by being a poor heat conductor, slowing the thermal energy as it tries to escape.
The latest insulation materials are often rated by their “lambda value”, a measure of thermal conductivity where a lower number is better.
We stock all of the most effective modern options, including those made from fibreglass, foam, polystyrene, and rock and glass mineral wool. These materials all display the key qualities you need from high-quality wall insulation. They:
- Are light – meaning they don’t allow heat transfer by conduction.
- Trap air molecules – so heat can’t cross the wall by convection.
- Have some mass – to prevent heat spreading by the process of radiation.
Does insulating your home save you money?
Yes. Around 33% of the energy wasted heating our homes passes out through the walls. This makes wall insulation a vital part of ensuring you don’t need to replace all that heat lost to conduction, convection, and radiation.
Poorly insulated homes are less comfortable to live in too. They are colder in winter and hotter in summer, a growing problem when extreme weather conditions like heat waves are on the rise.
Insulating your home’s walls is a smart investment for the future. The wall insulation in our online store is designed by the leading manufacturers in the UK and globally, enabling you to start reducing bill payments and stay comfortable no matter what the outside weather is up to.
How to insulate walls
When you’re working out how to insulate walls, the type of wall you have is the most important thing to determine. If you live in the UK, your home will have one of two types of wall:
Cavity walls – most modern UK homes have cavity walls. These consist of a brick layer and a block layer with an air pocket in between. To insulate them, you drill a hole into the cavity and inject a foam.
Solid walls – UK homes built before the 1920s often have solid walls. Working out how to insulate walls without a cavity is a little different. It can be done internally or externally, with each having a variety of benefits.
Types of wall insulation
Explore our huge online store to discover reliable, proven options for any type of wall insulation you might need:
External Wall Insulation
External wall insulation is affixed to the exterior of your home. It can be covered by rendering, cladding, tiles, panels, or even brick-effect slips. You need to have access to the exterior walls of your home. But the rewards of energy bill reduction, no internal disruption, added acoustic insulation, and repaired brickwork damage – reducing draughts and damp – are well worth it.
Internal Wall Insulation
There are numerous options when it comes to how to insulate walls internally. Installing internal wall insulation most often involves constructing stud walls filled with glass or rock mineral wool fibre or affixing insulation boards directly to the walls themselves. The process can be a little disruptive, but there are huge upsides.
Cavity Wall insulation
Most people trying to work out how to insulate cavity walls are surprised at how simple the process is. Essentially, all you need to do is drill tiny holes in the exterior wall, inject the insulation, and then seal it. There are different cavity insulation materials available in our store to suit every individual need and budget.
How much is wall insulation?
Typically speaking, the larger your property, the greater the cost of insulating a wall. But also, the greater the savings to be made. Factors unique to your home and any other insulation you may already have in place will also play a role.
The average cost of insulating solid walls will typically start from several thousand pounds. However, this could save you hundreds or even as much as a thousand pounds on energy bills every year.
There are also numerous grants and schemes available – such as the LWH (London Warmer Homes) scheme – that can help you save money.
How much is cavity wall insulation?
Cavity wall insulation is much more affordable than solid wall insulation.
The most common rule of thumb is around £200 for each external wall of your property. This means that insulating a detached house might cost around £800, but a terraced house £400. Single-storey homes like bungalows can cost half as much, and taller homes more.
Again though, it’s important to stack how much cavity wall insulation costs against how much it saves. Insulation can reduce your annual heating bills by hundreds of pounds.

The most commonly asked questions about wall insulation
Is cavity wall insulation a good idea?
Properly installed cavity wall insulation will reduce your energy usage and carbon emissions and make your home more comfortable to live in. It is also very cost-effective. However, it is always important to make sure you are choosing the right material for your property and that you know how to install it correctly.
Does cavity wall insulation cause damp?
No. The only occasions when cavity wall insulation can cause damp is when it has been improperly installed or your property’s external masonry was already damaged. In these circumstances, it’s unlikely that any kind of insulation would continue to protect you.
Is wall insulation on its own enough?
No, but it is a very good place to start. If you really want to minimise your energy bills, it is worth looking into how to insulate your floor, roof, and loft space too.
