Closed Cell Spray Foam Removal UK
Closed cell spray foam is the hardest type to remove. Our specialists have the tools and expertise to safely extract dense closed cell foam without damaging your roof timbers.
What is Closed Cell Spray Foam Removal?
Closed cell spray foam removal is the extraction of high-density, rigid polyurethane foam insulation. Closed cell foam is significantly harder to remove than open cell due to its dense structure (typically 2 lb/ft³ vs 0.5 lb/ft³ for open cell). It typically costs £65-80 per m² compared to £50-65/m² for open cell removal.
Closed cell foam adheres more strongly to surfaces and requires specialized cutting tools, more labor time, and careful technique to avoid timber damage.
