Cavity Wall Insulation - Fibre and Bead

Aran is able to provide 2 types of Cavity Wall Insulation material, providing the best possible solution to your properties requirements. Our technical assessment will confirm which product is suitable for your home. All materials are eligible for ECO grant funding, and installation warranties.

Blown Mineral fibre

Mineral wool Insulation also known as White Wool or Glass Wool. It is a dry fill system which uses granulated fibre blown into the cavity wall. The material is blown into the cavity space through a series of holes drilled in a specific pattern.

The mineral fibre is treated with a water repellent during the manufacturing process, so will not transfer water across the cavity, when installed correctly and in the correct scenario. This system has been used widely and has a proven record of performance, it is the most cost effective insulation solution.

Expanded Polystyrene (EPS) beads

When installing EPS small polystyrene beads are blown into the cavity space and bonded using a binding agent or PVA adhesive to hold the beads in place. It can often be used in harder to treat properties when the cavity might not be suitable for standard mineral wool.

Beads can be used to insulate properties made where the cavity is narrower than normal than the 50mm minimum allowed for mineral wool amongst other scenarios. Bead is a very thermally efficient form of cavity wall insulation and is water repellent. The actual installation process requires fewer drill holes than the other 2 systems.

EPS Polystyrene bead systems provide an alternative to mineral fibre and an insulation solution for many other properties. EPS Polystyrene beads can be installed in properties where access maybe inhibited by garages, conservatoires or other obstacles.
