Cavity Wall Insulation

Cavity wall insulation is done by either building an insulation board into the cavity during construction or by pumping an insulation and adhesive bead into the cavity after construction is finished.

No disruption to residents

B. Donaghey & Sons Ltd use cavity wall insulation installers to fill any void in cavity walls they encounter prior to fitting their external wall insulation.

This filling of any cavities stops "air looping" in the cavity and ensures the maximum effect is achieved from the external wall insulation.

With all the work taking place outside, residents can continue with their daily routines inside without disruption.
