Ventform

Ventform provides an excellent passive gas venting medium under suitably reinforced concrete ground floor slabs. 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
  • Provides a high degree of insulation and is manufactured from EPS which achieves a BREEAM rating of A+
  • Range of thicknesses and grades to suit most project requirements
  • Light, robust and easy to install 1200mm x 1200mm panels
  • Ventform panels are resistant to UV light, water and are flame retardant. They contain no CFC’s or HCFC’s

In addition to passive gas venting, Ventform panels also provide a high degree of insulation to the structure above. It is manufactured from expanded polystyrene (EPS) which achieves a BREEAM rating of A+.

Applications

Ventform panels are designed for use under suitably reinforced concrete slabs to form an insulated, passive gas venting layer.

Suitability

The appropriate grade of Ventform panel should be selected based upon the required equivalent void and maximum load capacity that it is required to support. This information is provided in the table below:
