What loft insulation is best?

The best insulation for your loft depends on the type of property you have and what you want to achieve. For instance, older homes with joist spaces may suit mineral wool, while modern loft conversions often use rigid PIR boards. For many UK houses, mineral wool rolls are the go-to choice. These are typically manufactured from glass wool or rock wool. They are affordable, easy to install, and offer excellent thermal and acoustic insulation. If you are short on space or want better thermal performance, go for PIR panels. PIR insulation boards offer high performance in thin layers.

What does loft insulation do?

Loft insulation traps heat inside in the winter and keeps hot air out in the summer. Experts say that up to a quarter of a home’s heat can escape through an uninsulated roof. Therefore, proper loft insulation can reduce heat loss by as much as 25%, helping lower energy bills. It will also help keep indoor temperatures comfortable all year round.

How does loft insulation work?

It slows the transfer of heat through the roof structure. Insulating products such as mineral wool contain millions of tiny air pockets that trap warm air. This means less heat escapes in cold weather and less heat penetrates the house in warmer weather.

Can loft insulation be used in walls?

Yes, loft insulation materials such as glass and rock mineral wool can be used in walls, provided the product is rated for wall applications. It provides comparable thermal performance and can offer good sound insulation, depending on density. Standard loft rolls are used in some wall applications, but cavity walls typically require purpose-made cavity insulation. Just check the label to make sure it’s certified for walls (fire safety and moisture regulations).

Will loft insulation stop condensation?

Loft insulation can reduce condensation, but on its own, it might not eliminate it altogether. This happens because insulation reduces the possibility of moisture forming on cold surfaces. But you still need proper ventilation to let moist air escape. When you insulate and ventilate the loft properly, it will keep condensation under control.
