Open Cell Spray Foam Removal UK
Open cell spray foam is softer and easier to remove than closed cell. Lower density means faster extraction, less specialist equipment, and lower costs.
What is Open Cell Spray Foam Removal?
Open cell spray foam removal is the extraction of low-density, soft polyurethane foam insulation. Open cell foam is easier to remove than closed cell due to its spongy structure (0.5 lb/ft³ vs 2.0 lb/ft³ for closed cell). It typically costs £50-65 per m² compared to £65-80/m² for closed cell removal.
Open cell foam is softer and can be scraped away more easily, though it still requires professional handling to avoid health risks and ensure complete removal.
