FAQs

Can I use the same insulation in walls, floors, and roofs?

Not all insulation suits every part of a building. Loft insulation rolls are made for horizontal surfaces, while cavity wall or acoustic slabs are designed for vertical applications. We can help you match the right product.

What’s the difference between acoustic and thermal insulation?

Thermal insulation helps retain heat and reduce energy loss, while acoustic insulation reduces noise transmission between rooms or floors.

Do I need adhesive or fixings with my insulation?

Yes. Adhesives like Bond It Mega Stik are used to secure insulation boards, plasterboards, or floor panels — especially for vertical or overhead applications.
