Cavity Wall Insulation - Fibre, Bead and Foam
Aran Services is able to provide 3 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 fillsystem 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 requiresfewer 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.
Polyurethane foam is a wall insulation suitable for 'random stone' walls and other non-standard cavities. It has excellent thermal benefits and its "closed cell" structure means it is totally water repellent and can be used in properties in exposed areas or that are prone to flooding.
The material is injected into the cavity and expands filling all gaps. This system can also assist the structure of walls as it binds to the inner and outer walls it can be used in walls where the wall ties have failed.
This system is the most expensive option but offers a solution to insulate cavity walls that we aren’t able to insulate with either mineral fibre or EPS.
