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. It may not be possible to do it for free under ECO4, however once completed the grant can cover the full cost of cavity wall insullation istallation.

Cavity extraction is typically done 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.
