Homeowners in the UK express feelings of betrayal as they face difficulties selling properties with spray foam insulation installed under a government scheme. Major lenders are rejecting homes with this type of insulation, citing concerns over potential damage. Nearly 250,000 homes are estimated to be affected, prompting calls for urgent government action. Affected homeowners like Robbie Anderson and Philippa reveal the financial repercussions and request accountability from the government, who initiated the insulation program.
