Room-in-roof insulation
Insulate the ceilings and walls of rooms directly under the roof.
Room-in-roof insulation is suitable for homes where the loft has been converted into a living space, such as a bedroom. It insulates the ceilings and walls of rooms directly under the roof, helping reduce heat loss in winter and keep rooms cooler in summer. This can improve comfort year-round and lower energy bills.
Insulation boards are typically fitted between the rafters (roof beams), with plasterboard applied over the top.
Before installing the insulation, it is important that you first repair any existing defects e.g. damp, rot, or infestation. A survey of your home should be caried out by your TrustMark accredited installer before fitting any insulation measures.
Some installers may recommend spray foam insulation. However, this type of insulation is not suitable for all properties and should be carefully considered before installation. If incorrectly installed, spray foam can restrict ventilation around roof timbers, potentially leading to condensation, damp, or difficulties in identifying roof defects. It may also affect a property's house value. For more information, visit the Which? guide to spray foam insulation.
There are grants and projects ongoing across the county to help residents make significant energy-efficiency improvements to their properties. This includes grants to fully-fund such improvements for those in fuel poverty or on low income.
