New Technology in Cavity Wall Construction!

  • SureCav is a moulded, recycled, polypropylene panel with spacer protrusions that forms the cavity and allows a stone, slate, brick and flint outer skin to be built without the need of an additional block leaf - this cavity protection system ensures clean and moisture free cavities.
  • Provides up to 5% extra floor area when using original external dimensions! 
  • Available in 25mm or 50mm wide panels for the perfectly protected clear cavity.

  • SureCav25 provides 25mm additional space in the cavity for insulation, enabling U-Values to be as low as 0.18 W/m2K in a 100mm cavity.
    BBA and LABC: All products approved.

    PREMIER GUARANTEE: All SureCav products accepted for structural warranty applications.
    NHBC: SureCav50 approved - awaiting approval for SureCav25 this April when test-build due.
