Closed-Cell Spray Foam Removal Cornwall

Professional Dry Ice Blasting by Kernow Insulation

Closed-cell spray foam insulation has been widely promoted for lofts and roofs, but many Cornish homeowners are now discovering the problems it can cause. This dense material bonds tightly to rafters and roof coverings, trapping moisture, concealing defects, and often invalidating mortgage or insurance applications.

Kernow Insulation provides safe, professional closed-cell spray foam removal across Cornwall, using advanced dry ice blasting technology to clean roof timbers without damage.

Why Remove Closed-Cell Spray Foam?

While spray foam can improve insulation performance, closed-cell types are not breathable and can cause serious building issues over time. Common problems include:

• Moisture becoming trapped against rafters and sheathing boards

• Concealed timber decay or corrosion of fixings

• Roof coverings unable to “breathe” or dry out naturally

• Difficulties obtaining a mortgage, remortgage, or property insurance

Removing the foam allows a full roof inspection, restoration of ventilation, and reinstatement with breathable, mortgage-compliant insulation.

Dry Ice Blasting – The Modern, Non-Damaging Solution

Dry ice blasting is the most effective and least invasive method for removing spray foam insulation. The process uses frozen carbon dioxide pellets accelerated under pressure. When they strike the foam, the rapid temperature change fractures the bond, and the ice instantly turns to gas — leaving no secondary waste.

Key advantages include:

• No water, no chemicals, and no abrasive media

• Safe for timbers, fixings, and membranes

• Clean, dry surface ready for inspection

• Environmentally responsible and residue-free

• Suitable for confined or delicate areas
