Firestone Adds a Fourth to its Capital Quarter Success in Cardiff

A fourth building has been completed using Firestone Building Products’ RubberGard™ EPDM waterproofing system for flat roofs at the prestigious Capital Quarter development, in the heart of Cardiff’s Commercial Enterprise Zone. The RubberGard™ EPDM roofing system has become part of a proven formula for success for developer, JR Smart, with four office buildings designed by architects Morgan2Morgan, using the system as part of a warm roof build up. As with the previous three office buildings, the RubberGard™ EPDM roofing system has been installed by Firestone Licensed roofing contractor, Envirotek Specialist Products. A further two office buildings are planned for the scheme and these are also anticipated to follow the same, proven specification. A seven-storey Grade A office building, No.4 Capital Quarter adds to a prestigious array of new build commercial buildings in Cardiff and the specification of the building has been developed to ensure it maintains its high-end aesthetic and performance over time. Envirotek covered the roof with a vapour control layer before installing a tapered insulation as part of the warm roof build up, creating falls for drainage. The RubberGard™ EPDM membrane was then fully adhered to the insulation with Envirotek completing all of the detailing, including the lightwell, the lift tower over-run and the roof-top plant room. Firestone’s RubberGard™ EPDM roofing system was also used to waterproof the building’s communal terraces at level 6, and paving slabs were laid over the membrane to create a hardwearing anti-slip surface. Paving slabs have also been laid to create walkways on the trafficable areas of the roof to enable maintenance teams to access roof-top plant, with support pads beneath all paved areas to protect the RubberGard™ EPDM membrane from abrasion and aid drainage. Neil Jones from Envirotek comments: “RubberGard™ EPDM roofing system is the ideal system for a project like this as it offers a flexible approach to waterproofing the roof that is fast to install without any requirement for hot works and provides excellent, long-lasting protection from the inclement Cardiff weather.
