Cavity Wall Insulating & Stabilisation Foam is a cavity stabilisation / insulation foam system.

Cavity Wall Insulating & Stabilisation Foam is a  CFC-free, rigid polyurethane foam system, injected into cavity walls to structurally stabilise and insulate. The system and MPI as installer are BBA approved (Certificate No: 97/3426).

When injected, the foam is a fluid, but it quickly expands and hardens to completely fill the cavity, bonding to the wall surfaces inside the cavity. The adhesive bond strength to masonry is in excess of 60KN/m2.

The system is closed-cell and waterproof, and with a K-factor of 0.024W/m can achieve U-values of 0.26W/m2/°C in a 65mm cavity. Full-scale tests have been carried out to BS4370 parts 1-4: 1988 by appropriate bodies; copies are available on request.

The method

  • Existing tie bars are located using a metal detector, inspected using a boroscope and isolated / removed as required.
  • 12mm holes are drilled in a staggered pattern in the mortar joints, the cavities inspected and cleared as required.
  • The foam is sequentially injected until the wall is filled.
  • Injection holes are made good with matching mortar.
  • Air bricks, vents and flues are checked to ensure no blockages have occurred.

The average installation time per house is only one day.

'Hard to Treat Homes'

Cavity Wall Insulating & Stabilisation Foam is an ideal solution for installation into a number of properties that would be classed as 'Hard to Treat Homes' such as houses built in the early 1900s with either a sub 50mm cavity or cavities of variable width, properties with no damp course or failing wall ties due to water penetration, and also houses or buildings unsuitable for traditional cavity wall insulation because of exposure to wind driven rain condions.

All installations are covered by a 25-year insurance backed warranty.
