Dry Ice Blasting Spray Foam Removal in Cornwall

Kernow Insulation – Safe, Precise and Effective Solutions

Many properties across Cornwall were fitted with spray foam insulation over the past decade, but growing awareness of its risks has led to increasing demand for safe, professional removal. Closed-cell spray foam, in particular, can trap moisture, mask roof defects, and cause problems with mortgage lenders and insurance providers.

Kernow Insulation offers a specialist dry ice blasting service for spray foam removal throughout Cornwall, providing an effective, non-damaging method to clean roof timbers and restore the structure for inspection or reinstatement.

Why Choose Dry Ice Blasting?

Dry ice blasting is a modern cleaning technology that uses solid carbon dioxide pellets accelerated under pressure. When the pellets strike the surface, they instantly convert to gas, lifting away foam, adhesive and contaminants without leaving behind any secondary waste or residue.

This process is ideal for delicate building materials and heritage structures, offering several key benefits:

• No water or chemical use – dry and residue-free.

• No secondary waste – the ice evaporates instantly.

• Gentle on roof timbers and fixings – non-abrasive and non-flammable.

• Highly efficient – reaches awkward or confined roof areas.

• Environmentally responsible – uses recycled CO₂ pellets.

Perfect for Roof Spray Foam Removal

Dry ice blasting is highly effective for removing both open-cell and closed-cell spray foams from:

• Roof timbers and rafters

• Pitched and flat roofs

• Boarding and sheathing

• Lofts and attic spaces

The method provides a clean, dry surface ready for structural inspection, timber treatment, or re-insulation using breathable, mortgage-compliant materials.
