Cavity Wall Insulation & Replacement

Flood waters can penetrate unprotected cavity walls and cause major damage to standard cavity wall insulation measures.

CavityWall1

Standard cavity wall insulation materials can absorb and retain flood water and lose their insulating properties or disintegrate over time and can be highly disruptive.
Wet or saturated standard cavity insulation can cause misery, upheaval, disturbance, and financial hardship associated with prolonged drying out and temporary family accommodation over many months if the saturated material within the cavities of walls is not promptly removed after the flood waters recede.

The Association of British Insurers (ABI), DEFRA, DCLG and the Environment Agency all advise that in flood risk areas cavity insulation should preferably incorporate rigid closed cell materials as these retain integrity and have low moisture take-up.

Many Local Authorities in flood risk areas are now replacing inappropriate standard cavity wall insulation within walls with closed cell polyurethane (PUR) insulation.

Replacing wet or saturated standard cavity wall insulation with BRE approved closed cell polyurethane flood resilient cavity wall insulation not only provides the best flood resilience performance but also the best thermal performance of all practical full cavity insulants, and the costs in connection with installation can be recovered through reduction in heat loss and savings on your energy bill.
