The EJOT JBS-R and EcoTek tube-washer fixing combination, which is designed for rapid installation of flat roof systems with tapered insulation, has been instrumental in market-leading retirement property developer McCarthy & Stone meeting the strict completion deadline at one of its latest developments in Wiltshire.
The scheme at Wichelstowe in Swindon consists of two blocks which accommodate a range of one-and two-bedroom apartments designed to oĪer stylish independent living for the over-60s, with around 120 new properties in total.
The original proposal was for a tapered insulation system, incorporating a Bauder PVC membrane plus mineral wool insulation, to be bonded to the concrete deck. However, given the cold weather conditions at the time of the installation window, it was not possible to apply the adhesive and an alternative had to be found.
Nationwide roofing contractor Protec Roofing was tasked with finding a solution to ensure the proposed flat roof system could still be used. Its Managing Director, Ian Green, approached EJOT UK’s flat roofing specialist Kevin
Rackley for assistance and the JBS-R fastener and EcoTek tube-washer combination was subsequently approved for use by Bauder.
The combination brings together a high-performing, organically-coated concrete screw (JBS-R 7.5) with a high-quality telescopic tube-washer (EcoTek) to provide a fixing solution that is adjustable to fit the require depth of insulation. It is suitable for all types of commonly-used tapered insulation, principally mineral fibre, EPS, XPS and PIR
