Open-Cell Spray Foam Mortgage Issues Updated for January 2026 # Open-Cell Spray Foam Mortgage Issues Open-cell foam is sometimes accepted by UK lenders — here's how to maximise your chances, and when removal is still the safer route. ## Why open-cell is treated more leniently Open-cell foam is softer, more breathable and far easier to remove than closed-cell. Some lenders accept it with full documentation, particularly when applied between rafters with appropriate ventilation maintained. ## When open-cell still fails - No installer documentation. - Foam applied directly to membrane with no ventilation gap. - Visible signs of moisture or condensation. - Aged installations with no recent inspection. ## Improving your position Get an independent inspection that confirms foam type, breathable application and timber condition. Combined with installer paperwork, this satisfies a meaningful minority of UK lenders. ## Frequently asked questions How do I know if it's open or closed cell?＋ Open-cell is soft and spongy when pressed; closed-cell is rigid. An independent surveyor can confirm with certainty. Is open-cell easier to remove?＋ Yes — typically 30–40% cheaper than closed-cell removal. Does the EPC reflect the foam type?＋ Not reliably — EPCs note insulation but rarely the foam classification.
