Glidevale has introduced a re-engineered version of its gas protection membrane, the Protect GDB10 Plus. Achieved by increasing the robustness of the material, the membrane’s puncture resistance has been boosted by more than 30%, ensuring less risk of tearing and ripping on site. Providing a continuous, impermeable protective barrier against ground gases including methane, radon, carbon dioxide and hydrocarbons, the membrane is suitable for Amber 1 and 2 applications as defined by NHBC. The product is compliant with BS 8485:2015 and has also been independently assessed and certified by BM TRADA.
As required by BS 8485, both the membrane and the joint integrity have been tested for methane resistance. Furthermore, Protect GDB10 Plus is one of the only products on the market that has been independently methane permeability tested to BS ISO 15105-1 for joints. This provides peace of mind to contractors and housebuilders that the product will create a fully sealed system.
Glidevale also supplies a range of purpose designed, pre-formed accessories to maintain protection at wall cavities, corners, and services to remove the need to form difficult shapes on site. A range of underfloor and cavity wall ventilation accessories removes gases and moisture vapour where required, enabling regulatory requirements for ventilation to be met. 150mm wide gas jointing tape is needed to seal the overlaps, providing a simpler fixing solution to save time on site.
