Ventform is a moulded EPS panel developed specifically for venting harmful gases from beneath buildings. Available in two types and a choice of grades. Ventform is suitable for both ground-bearing applications and for use beneath suspended ground-floor slabs.
Versatile Ventform is available in different densities; and in round- or square-legged configurations for use below suspended ground floors and ground-bearing slabs.
High performance Ventform has excellent venting characteristics and is fully compatible with all commonly used perimeter venting systems.
Loadbearing Ventform is able to support loadsup to 50kN/m2.
Permanent Ventform provides an ideal surfaceon which to lay a gas-protection membrane, and is rot-proof and durable. It will withstand the conditions encountered below ground, and will not degrade in the presence of high levels of ground water or precipitation.
Easy to handle Ventform is manufactured from expanded polystyrene (EPS), and is lightweight and easy to handle.

Approvals Ventform has been assessed and approved by Wimlas Ltd to confirmits suitability for use as a ventilation void former for supporting cast in-situ concrete slabs in either suspended or ground-supported floor applications; Certificate of assessment number 031/96.
Type All Types are supplied as Euroclass E, flame-retardant additive material, as defined in BSEN 13163. Ventform 80 and 100 have high load-bearing capacities, and are intended for relatively low gas risk applications; Ventform 150 and 200 provide increased gas ventilation performance but have a lower loadbearing capacity.
Thermal Insulation Although not designed specifically for this purpose, the use of Ventform panels will typically provide an improvement in the Uvalue of a 50m2 ground floor from 0.8W/m2K to 0.35W/m2K. Further information is available from Cordek Ltd.
