Traditional Mineral Insulation

It is a fact that traditional mineral fibre loft insulation laid at ceiling level, and at a depth of 270mm, the current UK government standard, offers a better standard of insulation than 100mm of spray foam installed between the rafters. This information is provided by the Royal Institute of Chartered Surveyors (RICS), in their spray foam update report published in March 2023.

It is a fact that traditional loft fibre insulation is considerably cheaper than the spray foam insulation many people have recently purchased for their loft space. The average cost of spray foam insulation is over £3,500 and as soon as you have spray foam insulation, you will not be able to sell your home to someone who needs a mortgage, you will not be able to get equity release, but with traditional loft insulation like mineral fibre or mineral wool you can still sell your house, you will be able to get equity release and it will keep the heat  in the living quarters of the property not the loft space.
