Cavity Wall Insulation & Stabilisation

cavity-wall01For wall insulation injected polyurethane foam can be used in the cavity for a superior performing insulation which also helps to bond the inner and outer leaves providing strength to the building.

Benefits:

  • Superior insulant
  • Bonds the inner and outer walls together (where wall ties are failing)
  • PU foam is a satisfactory replacement for normal metal wall ties
  • Flood resistance, so may be the material of choice in areas prone to flooding (PU materials approved under BBA certification in all exposure zones)
  • Bring the walls up to current Building Regulations
  • The insulant acts as a barrier to heat loss, prevents draughts
  • Reduces airborne sound
  • Closed cell polyurethane foam provides an extra layer of resilience against the ingress of flood water through the cavity
