In the UK, houses have been built with cavity walls since around 1920, the majority of which were built without cavity wall insulation materials. The cavity was originally designed to stop homes getting damp.

From 1920, most homes in the UK were built with cavity walls, or 2 exterior walls. This became the construction standard to prevent dampness and condensation from entering the home. However, you may be losing as much as 40% of your heat through your walls if they are not properly insulated.

If your home was built after 1989, it is very likely that the walls were insulated at the time of your home's construction. If your house predates this period and you have not had insulation installed, you will be spending thousands of pounds in unnecessary heating costs over the lifetime of your home.

As long as your home has a space of at least 50 mm between the two walls and the outdoor masonry is in good condition, cavity wall insulation can be installed. However, if there are any dampness or mould problems in your home, these will need to be corrected first before cavity wall insulation can be installed.

Installing Wall Cavity Insulation

Installing wall cavity insulation is not a job that can be accomplished by a do-it-yourself approach. Since it is specialized work, it requires the expertise and knowledge of a professional insulation installer and should be done by a contractor registered with the National Insulation Association, the Cavity Insulation Guarantee Agency or the British Board of Agreement.

To install cavity wall insulation, holes of about 22 mm in diameter are drilled into the exterior wall at about 1.5 meters apart in all directions. The insulation is then blown into these holes until the wall is filled. The main materials used are chopped glass or mineral fibre, white foam (urea formaldehyde foam) or bonded bead (white polystyrene beads). Afterwards the holes are filled with matching brickwork and mortar to conceal where the drilling took place. The entire job takes only about 3-4 hours from start to finish.

The drilling will cause some vibration inside the home so pictures or ornaments hanging on the walls will need to be taken down during the installation. Also some dust will be stirred up from the drilling so outdoor furniture or vehicles should be removed from the area. We are happy to offer a no-obligation free estimate and consultation to help you consider all of your needs and concerns in making your home energy efficient.

 Cavity Wall Insulation - FAQ

Cavity wall insulation - what's it all about?

The external walls of a house are actually made of two walls, an inner wall and an outer wall, with a gap of at least 50mm between them. The cavity was originally designed to stop homes getting damp and if your home was built from 1920 onwards, it's very likely that the external walls are made of two layers with a small gap or 'cavity' between them, hence the name Cavity Wall.

Insulating your cavity walls means filling that gap, there are very good reasons for this.

Why insulate your cavity walls?

The cost of cavity wall insulation can be subsidized by government grants and is an effective way to save energy and money at home by keeping insulation prices down. This process will keep your house warm and save you money also to heat your home more efficiently. Using less energy reduces carbon dioxide emissions (CO2): reducing your carbon footprint.

Cavity walls and insulation can also help to reduce condensation inside the house if it is a problem on external walls.

Find out how cavity wall insulation works

Cold air moves to replace hot air, due to its density, cold air will displace the warm air in your home if your walls and or loft are insulated.

Cavity wall insulation slows down the rate at which heat escapes, keeping as much of it as possible inside your home. Insulation makes it much more difficult for heat to pass through your walls by filling up the cavity with a suitable material. U value is the rate at which heat escapes from a building, which normal is around 1.5 to 0.5 W/m2K. The lower the U value, the slower heat is lost meaning a saving on energy, not requiring constant heating to keeping the home warm.

What could you save?

Cavity wall insulation is not only cost effective but does not require any maintenance and by insulating your cavity walls you could reduce your heating costs by up to 15%, and by saving energy, your household will produce less CO2, great way to help fight climate change. .

The installation cost is low because it is part funded by the major energy suppliers under Carbon Emissions Reduction Target (CERT); Cost for a typical house, 3 bedroom semi-detached house, without the funding would be around £500.

The government offers grants and other funding options for a full list of what you could be entitled to please email us at cavity wall insulation installers.

How do I check my walls need insulation?

In the last 10 years walls built in The UK have had their cavity filled to help with the insulation, it is more than likely if your house is less than 10 years old, the cavity has been filled. Not all walls that have insulation are suitable for it. In some cases where rainwater directly hits the walls of the house, make sure that you have the right type of insulation for your home. Please click here to see our highly recommended insulation fitters. If you are sure your home is not suitable for cavity wall insulation, why not think about solid wall insulation?

How do I identify whether I have cavity walls?

1. Does your home have cavity walls?
   

   If your house was built was built from 1920 onwards but not 10 years old you may have cavity in your walls that allows heat to escape.
   
   Solid walls have the bricks in an alternating pattern like this.
   
   If the brickwork has been covered, you can tell a cavity wall by measuring its width; go to a window or door on one of your external walls, and take a measurement there. If the wall is more than 260mm deep then it may have a cavity; a much narrower wall suggests that it's solid.

2. Are your cavity walls unfilled?
   
   

   If you think you have cavity walls and want to check whether they are already filled you can:

   • Ask a registered installer.
     
     They may have to drill a small hole in your external wall, which will show you if your walls are hollow or filled. This is called a boroscope inspection, and will sometimes be carried out when an installer comes to assess your homes suitability for cavity wall insulation.
     
     
   • Check with your local authority's building control department
     
     They might know if your cavity walls have been filled already.
     
     
3. Are your external walls easy to access?
   
   

   Cavity wall insulation is blown into the cavity from the outside of a house. Every part of the wall must be filled with insulation, so it's important that the installer can reach all your external walls.
   
   If your houses? external walls are joins to a house next door, the cavity will be separated at it's dividing line, this involves the installers inserting a cavity barrier to ensure the insulation is contained so that your neighbours aren't affected.

4. What if there is damp?
   
   

   You should speak to a builder who specialise's in damp prevention about this, as you cannot have insulation if your house has damp on its walls.
