What is it?

OptiPlan-FB is a fibreglass reinforced, fleece-backed synthetic waterproofing membrane, made from premium quality plasticised polyvinyl chloride (PVC-P). The upper layers offer exceptional resistance to weather and UV rays, whilst the membrane underside features a laminated geotextile fleece, providing both a separating layer and a surface for applying adhesive.

OptiPlan-FB is also available with a slip-resistant top surface and can be installed year-round due to having excellent flexibility in cold temperatures.
