Description
It provides a passive gas venting medium. When used in combination with perimeter vents and a suitable gas membrane system, it will provide an effective method of protecting structures against the ingress of harmful ground gases.
Features and benefits:
- Highly effective venting medium suitable for ground gas affected sites as part of a gas protection system.
- Provides a high degree of insulation and is manufactured from expanded polystyrene which achieves a BREEAM rating of A+.
- Range of thicknesses and grades to suit most project requirements.
- Light, robust and easy to install panels.
- Ventform panels are resistant to UV light, water and are flame retardant. They contain no CFCs or HCFCs.
