The overall energy savings by installing spray foam insulation completely depends upon the type of property you own. Homeowners can save around £380 on their energy bills for a detached house by insulating their house with spray foam, approximately £165 for a detached house, £150 for a mid-detached house and around £235 for a detached bungalow.
According to some research, spray foam insulation can reduce your energy costs by as much as 50% when compared to conventional house insulation products.
