What are the benefits of using rigid PIR insulation boards?

Rigid foam boards, such as PIR (Polyisocyanurate), offer exceptional thermal performance. Because of their highly efficient closed-cell structure, you get maximum heat retention from a very thin board. This makes them ideal for areas where space is at a premium and you want to avoid losing headroom or floor space, such as under floors, within cavity walls, and in pitched roofs.

What is mineral wool insulation made from?

Mineral wool (often referred to as glass wool or rock wool) is a highly flexible insulation material created by spinning molten glass or volcanic rock into fine fibres. It is a highly sustainable option, as glass mineral wool is typically manufactured using up to 80% recycled glass combined with natural sand.

Which type of insulation is best for soundproofing?

For acoustic insulation, mineral wool is the superior choice. Its porous, open-cell structure naturally traps air and effectively breaks down sound waves, greatly reducing noise transmission between rooms. In contrast, rigid foam boards are engineered primarily for thermal efficiency and do not absorb sound waves nearly as well.

What is a cavity closer and what does it do?

A cavity closer is a purpose-built, pre-formed insulation component that fits securely within the gap (or cavity) between the inner and outer layers of a brick or block wall. They are specifically installed around the edges (reveals) of window and door openings. Their main job is to seal these exposed gaps to prevent heat from escaping (cold bridging), whilst simultaneously acting as a damp-proof barrier to stop external moisture and drafts from penetrating the building.

Why is cavity wall insulation so important?

If you have an empty cavity wall, the warm air from your heating system easily escapes into the gap and out of the building. Cavity wall insulation acts like a thermal blanket, trapping the heat inside your home during the winter and keeping the property cooler during the summer. Energy consumption will generally be lower after installation.
