Why Do You Need To Get Rid Of Your Insulation Foam?

Over the last month, some homeowners, landlords and property managers may have received advice if not outright instruction to arrange for spray foam removal for their cavity loft insulation.


In April 2024, the UK Government and the Health and Safety Executive expanded their advice and concerns regarding spray foam insulation, with both the rigid closed-cell foam and softer open-cell foam being a cause for concern, especially when added to a home after its construction.


Not every spray foam insulation installation is necessarily bad or harmful, and it is vital you consult with an expert and have your insulation surveyed before getting it removed by a professional. When installed correctly, spray foam is an effective way of retaining heat.


The issue is that it can often be installed incorrectly or in an incorrect place, both of which can cause significant concerns regarding the building’s health.


In the case of closed-cell insulation, the problem is that if installed in an unsuitable loft cavity, such as one that may have an issue with humidity, it can create condensation by restricting the circulation of air which can cause the structurally vital roof timbers to rot.


Whilst open-cell is better, there is also a risk of timber rot if it happens to be installed in the rafters.


In both cases, it typically needs a professional to install and absolutely needs a professional to remove, and there are cases when you might have to do so.


The biggest issue is when selling a home or trying to release equity from it, as some mortgage lenders will either demand a professional survey of the insulation once they find out about the foam or they will outright refuse because of fears that the structure of the building has been compromised.


There are many alternative options for insulation, and whilst quick to install, spray foam tends to be an expensive option notwithstanding its removal costs.
