Bonded Bead Cavity Wall Insulation provides a complete fill across the cavity to prevent water from passing to the inner wall. Its thermal properties meet the U-value requirements set out in building regulations and ensure your home stays warmer for longer. Ideal for both new builds and existing homes.
Bonded bead insulation works best for:
We drill small holes in the outer wall to access the cavity.
The bonded beads and adhesive are blown into the wall until the cavity is completely filled.
