What is Room in Roof Insulation?
Room in roof insulation involves fitting insulation boards between the rafters and beneath the plasterboard on sloped ceilings, gable end walls, and flat sections of a converted loft room. This creates a continuous thermal envelope around the living space.
By trapping heat within the insulated area, it allows you to maintain a comfortable temperature without using as much energy - reducing both your heating bills and your carbon footprint.
Key Benefits of Room in Roof Insulation
Room in roof insulation turns cold, draughty loft rooms into warm, comfortable living spaces.
- Prevents heat from escaping, keeping your roof room warmer for longer.
- Eliminates cold spots and draughts, creating a consistently comfortable space.
- Reduces external noise through the roof structure for a quieter indoor environment.
- Protects against moisture build-up and reduces the risk of condensation and mould.
- Delivers a neat, plasterboard finish ready to decorate as you choose.
- Reduces energy consumption and your household carbon footprint.
