Cavity Wall Insulation

Not sure what type of wall insulation you need? Well, if your building was constructed post-1930s and the brickwork is presented on its long side, rather than an alternating long-short pattern, chances are it has cavity walls. Given all the boxes are ticked, cavity wall insulation is a great option for insulating your property. Here’s what you need to know before you buy:

Choosing the right insulation material

The best cavity wall insulation for you will depend on a few factors. This includes choosing the right material and form, which you’ll need to consider your climate conditions and therefore your thermal performance needs, as well as cavity wall insulation cost considerations. With lots of options, it’s best to chat to a specialist to find the best fit:

• Mineral wool fibre: Can be made from stone, slag, and molten glass. It’s cost-effective and easy to install.
• Sheep’s wool: An eco-friendly option with properties similar to mineral wool.
• Rigid insulation boards (PIR): Excellent for heat retention and moisture resistance.
  Polystyrene beads: Lightweight, durable, and budget-friendly.

Types of external cavity wall insulation

Cavity wall insulation slabs are ideal for flat surfaces requiring coverage, offering thermal and acoustic insulation, water repellency, and fire resistance.

Rolls are perfect for uneven surfaces or around obstacles like pipes, providing effective heat insulation and sound absorption. However, they can require additional fixtures like insulation supports to prevent movement, so make sure to keep that in mind.
