Keep homes warmer and reduce heat loss with our range of Loft & Roof Insulation, ideal for improving energy efficiency in both new builds and renovation projects. Insulating lofts and roof spaces is one of the most effective ways to improve comfort and lower heating costs, helping maintain a more consistent indoor temperature throughout the year. Whether you’re topping up existing insulation or insulating a new roof build-up, the right products help deliver long-lasting performance.
Loft and roof insulation is commonly used in loft spaces, pitched roofs, attic conversions and roof voids, helping prevent heat escaping through the top of the property. It can also support sound reduction and improve overall building performance when installed correctly. Choosing insulation suitable for your roof type and ensuring full coverage without gaps helps maximise results and reduce cold spots or drafts.
For best results, fit insulation to the correct depth, maintain ventilation where required, and avoid compressing materials which can reduce performance. Using compatible membranes and sealing products can also help improve efficiency by reducing air leakage and moisture risk.
