Attic insulation: everything you need to know

Since a quarter of our homes’ heat is lost through the roof, loft and attic insulation is a go-to solution for reducing the amount of heat escaping, which also lowers energy bills. In fact, loft insulation is one of the most common types of insulation on the market, and there are plenty of materials you can use to make an attic or loft insulation project a success.

If you plan on offering loft insulation installation services, here is what you need to know first.

Selecting the right insulation material

The choice of insulation material profoundly influences project success. Opting for premium insulation materials ensures extended lifespan and superior thermal efficiency. 

Insulation rolls crafted from mineral wool, endorsed by brands like Knauf Insulation and Rockwool, effectively enhance energy efficiency, cutting energy costs and carbon footprints. 

Roof insulation boards from reputable manufacturers like Unlin Insulation (formerly Xtratherm) provide versatility, while Ravago’s XPS is a purpose polystyrene for the thermal insulation and frost protection of inverted flat roofs, green and blue roofs. 

Multi-foil insulation, such as YBS Insulation’s solution, addresses damp-prone homes and offers vapour control, while accessories like breather membranes and vapour control layers can further enhance performance.

Factors influencing material selection

Several factors inform insulation material selection, including type of roof, weather climate, ease of loft access and specific client requirements. 

Acoustic properties may drive the choice, particularly for noisy environments, while fire safety concerns may lead to the preference for non-combustible materials with A1 classification.

Every property is unique with its own set of needs and requirements, so choosing the right insulation material isn’t always as clear-cut as it seems.
