Cavity wall insulation
Heat loss through your walls accounts for 35% of the total heat loss in a home. Cavity wall insulation is a cost effective method of reducing this heat loss.

Wall insulation
22mm holes (about the size of a €1 coin) are drilled in the external wall. Bead insulation is then pumped into the cavity. The bead is coated with an adhesive. This bonding agent allows the bead to flow freely until the cavity is completely filled. The adhesive then sets to prevent any sinking, settling or cracking.
We can fill walls where there is no insulation or where some insulation already exists. The holes are then repaired with coloured plaster, or paint if available.
Material used
We use Warmfill super silver bead insulation. Warmfills bead is certified at 0.031Wmk i.e 0.25 U-value in a 110mm cavity. This is the lowest certified U-value of any bead on the market. The unique draining qualities of warmfills super silver bonded bead allows the cavity to drain, breathe and remain dry.
