  • Size

This combination does not exist.

  • Strong lightweight rigid insulation made from thermoplastic foam, based on polystyrene.
  • Thermal conductivity: 0.046 W/m.K and Density: 200 kg/m3
  • Ideally suited for support for door thresholds and window installation, where it is important to minimise thermal bridging.
  • Wide range of applications where structural support and the possibility of obtaining secure fixings into the material are required.
  • Can be used as a replacement for timber battens in these applications, where thermal bridging is to be reduced.
  • High compressive strength with good screw pull-out resistance and easy to drill & saw
  • Available with Parabond 600, a fast curing, elastic white adhesive with high initial bonding strength suitable for securing Compacfoam to building materials and itself

    Using Compacfoam

    • The best way to cut Compacfoam is to use saw blades with large distances between the teeth or milling blades, to avoid the material ‘melting’. More information
    • You can use Compacfoam blocks in an external wall insulation system to provide firm fixing for drainpipes.
