Ventform Plus provides an excellent passive gas venting medium under suitably reinforced concrete ground floor slabs with the additional benefit of incorporating below-slab insulation. When used in combination with perimeter vents and a suitable gas membrane it creates a highly effective method of protecting structures against the ingress of harmful ground gases.
Features
- Highly effective venting medium suitable for ground gas affected sites as part of a gas protection system
- Integrated Filcor insulation to suit U-value requirements.
- Range of thicknesses and grades to suit most project requirements
- Light, robust and easy to install 2400mm x 1200mm panels
- Ventform panels are resistant to UV light, water and are flame retardant. They contain no CFC’s or HCFC’s
Applications
Ventform panels are designed for use under suitably reinforced concrete slabs to form an insulated, passive gas venting layer.
Suitability
Please note to establish the complete product specification, the Ventform Plus panel type must be established, based upon the required ventilation clear void and maximum loading conditions. The panel thickness also needs to be calculated based on the U-value requirement to complete the specification.
