What is cavity wall insulation?

Cavity wall insulation is used to store heat within a home and bounce it back into rooms, allowing the heat to be retained for longer. This means you have to spend less money on heating bills and you can improve your energy efficiency. It also allows for a more consistent temperature in a house and can give you savings of up to £275.

The majority of cavity wall insulation should last at least 25 years, but alterations to the outer walls of a house may cause it to break down and degrade earlier than that, which can increase cold air, damp issues and heat loss in a home as well as possible health problems.

Through the government’s Energy Company Obligation (ECO) scheme, it is possible to have the entire removal and installation of cavity walls insulation funded without cost to you.

How does cavity wall insulation work?

Cavity insulation in walls works through taking the heat that is in a house and bouncing it back into the room, therefore allowing the house to stay warm for longer without raising energy bills for the people living there.

Modern insulation is typically mostly water resistant and made of either mineral foam, blown bead, or mineral wool. When installed correctly, there is less of an increased risk and there should be outstanding durability. The special material in insulation acts as a barrier between the outer cavity wall and the internal wall, meaning there should be more heat being kept inside and less of a chance of damp problems.

Cavity wall insulation removal FAQ

How is it installed?

It is done by injecting special insulation material (this used to be urea formaldehyde) through specific holes in the outer wall to reach the cavity wall beneath. This means hoses can be inserted which are filled with the material and allows them to be spread with even distribution throughout the cavity wall, removing any holes. The walls are then sealed with UPVC glue.

However, certain homes are not suitable for cavity wall insulation; those that are suitable are:

  • The external walls are unfilled cavity walls
  • It was built between 1920 to 2005
  • There’s small risk of your home flooding
  • Your walls are not under constant exposure to wind driven rain
  • The bricks and masonry are in good condition according to building regulations
  • You are on a qualifying benefit
  • Frequent driving rain and other weather conditions don’t hugely affect your property

How is cavity wall insulation removed?

To remove cavity wall insulation, it is necessary to contact a company registered to do it. This is because incorrectly installed insulation may be dangerous to remove if not handled correctly.

It is removed through blowing compressed air into a hole in the outer leaf wall as an industrial vacuum is used to collect the remaining old insulation and makes sure that there isn’t any remaining insulation material that may rot and cause damp spots. To remove cavity wall insulation, the process is typically done from the bottom up of a house, to ensure that there is nothing left behind in the upper parts. All of the debris is then packaged and removed from the property, to be disposed of safely by our services. Typically photographic evidence of roughly a square metre is taken to study whether or not the cavity has been fully emptied between the two walls to prevent future damp on your property.

Once everything has been removed, it is possible to refill the cavity wall with brand new and effective insulation material to ensure that there is no cold air or damp coming into your home and that the heat remains inside for as long as possible. One of the most effective ways to prevent water from travelling through the internal walls is with polyurethane foam. To install cavity wall insulation back into the house, workers need to be sure that the outside walls are capable of withstanding the building work.

Why do I need cavity wall insulation removed?

If you have old cavity wall insulation, and it is showing signs of damage, there is a good chance it needs to be removed and replaced.

This is typically because of the UK climate; as we experience a lot of rain, cold, high winds and ice in the UK, our homes often take damage to the bricks and on occasion, the cavity walls themselves. Over time, EON, Scottish Power or British Gas cavity wall insulation (or eny other energy provider as a matter of fact) may begin to break down due to our wet climate, which can be dangerous for human health as well as creating cold spots in your home’s heating.

Cavity wall extraction allows your property to remain safe from damp and other problems.

What are the health risks behind old wall insulation?

Increased damp issues and moisture build-up can lead to serious illness and health risk. Penetrating damp is a particular risk in the UK due to our higher moisture content from rain. Defective insulation material that is wet can cause respiratory illnesses, allergic reactions and other lung based conditions, such as asthma.

It is important to ensure that your poor cavity wall insulation isn’t damaged because it can release toxic fumes into the air of your home if it is old or installed incorrectly. Cavity wall insulation removal may seem like an extreme measure but it is necessary in most cases to protect your health and home from the risks of damaged insulation.

It’s best to get a professional in to check that the quality is still maintained before cavity wall insulation removal on your property.
