Loft Insulation Thickness Regulations
A quarter of heat is lost through insulated roofs, so it’s worth reviewing loft insulation regulations and addressing your current loft insulation. Not only could you save money and retain warmth in your home for longer, but you’ll be adhering to the government’s energy saving initiatives. Icynene® offers up to 50% savings on energy costs, which is more than any other spray foam insulation on the UK market.
The recommended loft insulation thickness regulations have changed over the years, and a thicker layer of insulation is required.
How Much Loft Insulation Do You Need?
UK loft insulation building regulations state that a minimum depth of 270mm is required to ensure that it is properly insulated, and your home is protected. Loft insulation regulations request that the minimum is met to reduce heating usage and lower energy bills.
What Are The Roof Insulation Regulations?
The maximum U value required under roof insulation regulations, as stipulated by the building regulations that must be adhered to, is 0.20W/m². To achieve this, you will need a thickness of 120mm of rigid foam. We recommend Icynene® closed cell spray foam as it offers the highest level of air-tightness, preventing air-leakage, infiltration and heat loss. Alternatively, natural or mineral wood insulation can be used at a thickness of 200mm.
