What is Cavity Wall Injection? – Wall Insulation

Cavity wall injection is one major form of insulation for cavity walls. It is a simple and effective method to provide insulating capabilities to your walls.

First and foremost, you need to make sure you are familiar with what a cavity wall is. There are a few signs you can look out for to check whether your property has cavity walls. For example, if your brickwork has an even pattern, if your walls are thicker than 260mm and generally speaking if your property was built post-1920. You can check out our complete guide to cavity wall insulation to find out more.

So, what actually is cavity wall injection and why is it superior to other forms of insulation for cavity walls?

 

Understanding Cavity Wall Injection

Cavity wall injection is the process of injecting insulation into your walls via strategically drilled holes in your exterior walls. This method allows for a fast and effective insulation method to get your property insulated.

Additionally, the holes are then filled in with cement after your cavity wall has been insulated, creating an effective solution with no exterior damage.

There are a variety of options of insulation material you can choose from that can be injected into your walls, all of which can affect the price and timeline of the job. When you hire an installer, you can discuss your options with them and find the best solution for your job.

At EcoSpray-Foam Systems, our members are on the board of the National Insulation Association, a member of the Cavity Insulation Guarantee Agency (CIGA) and of the British Board of Agreement (BBA). We have the accreditations, expertise and experience to help you with any insulation project you may have.

 

5 Benefits of Cavity Wall Injection

We recommend injecting your cavity walls with EPS beads which can create an effective insulation solution for your exterior wall. The benefits of EPS bead insulation are as follows.

 

1. Thermal Performance

Insulating your walls with EPS beads can improve the U-Value of a room by up to 70%, which is significantly higher than the standard insulation materials. The beads help to reduce the transfer of heat between materials and surfaces, creating a superior thermal performance for your property.

2. Money Saving

With your cavity walls insulated, you will notice that you can now rely less on heating or cooling your home because heat is better conserved inside during winter and your rooms are kept cooler during the summer months. Therefore, by relying less on energy-consuming devices such as heaters and radiators, you are effectively reducing your energy bills.

3. Low Build Cost

EPS bead cavity wall injection requires fewer materials and time to be installed correctly. Because it is so minimally invasive, the “build cost” of the project is also lower. Due to the reduction in materials needed for insulation, there are lower overheads when injecting EPS beads.

4. Minimally Invasive

All that is needed is some holes drilled in specific places across your exterior cavity wall, then, using specialist machinery to inject insulation (such as EPS beads) into the cavities of your walls and finish off by cementing the holes.

5. Moisture Resistant

Injecting your exterior walls with EPS beads can help with moisture control because the insulation material used does not contain absorption properties. What does this mean? EPS beads prevent mould growth and moisture, keeping your cavity walls clean and protected, unlike if you were to use more traditional injected forms of insulation such as blown-in fibreglass.
