Spray foam insulation failing building regulations
Why it happens here
Much of the foam in Barking and Dagenham was installed before ventilation standards were properly enforced. It seals the roof space without leaving an air path, so it fails the ventilation requirements that Building Regulations Part L now expects. Surveyors pick this up quickly.
Our approach
We remove the foam, clear and reopen the ventilation path, and leave the loft ready for insulation that meets Part L. If you need documentation for a lender or buyer, we photograph each stage so you have a clear record of what was done.
