Polyfoam™ XPS – the extruded polystyrene insulation manufactured by Ravatherm UK – has received a British Board of Agrément (BBA) certificate for its inverted roof system and floor board insulation.
Ravatherm UK’s Polyfoam XPS floorboard and inverted roof solutions passed a series of comprehensive and independent assessments set by the BBA, including laboratory tests, on-site evaluations and quality management inspections. The BBA certification complies with Building Regulations and the National House Building Council (NHBC) Standards, and demonstrates exceptional design considerations as well as technical and installation guidance.
With its headquarters based in Hartlepool, Ravatherm UK’s Polyfoam XPS was assessed on the thermal performance, durability, condensation risk and resistance to foot traffic on its inverted roof system. The extruded polystyrene (XPS) board is used with a water-control membrane in inverted flat roofs, as well as pedestrian-trafficked balconies and terraces with either zero pitch roofs and slopes between 1:80 and 1:6.
The BBA certificate also covers Ravatherm UK’s Polyfoam XPS Floorboard Standard and Extra, which can be specified as thermal insulation on ground-bearing or suspended concrete floors in new and existing buildings. The Floorboard products can be specified for both domestic and non-domestic use and remain effective as an insulation for the life of the building.
Managing director of Ravatherm UK, Stuart Bell, comments: “The BBA certificate showcases our continuous commitment to providing fully tested and accredited solutions to the marketplace, and ensures Polyfoam XPS not only meets but exceeds our customers’ expectations.” The BBA certificate follows recently achieved International Organisation for Standardisation (ISO) certificates for Ravatherm UK.
Ravatherm UK, which sits within the Ravago Building & Construction Solutions (RBCS) division, is one of five XPS manufacturing plants across Europe. This historic cornerstone of the Ravago Group has grown from a local Belgian activity in the sixties to a pan-European division dedicated to developing and distributing specialised building and construction solutions across European, Turkish and CIS markets.
