EshaFlex 370 FireSafe

EshaFlex 370 FireSafe cap sheet is a fire protection top layer for EshaFlex exposed flat roofing systems, providing a zero spread-of-flame risk and eliminating the potential for fire penetration. EshaFlex 370 FireSafe will not readily support a flame and subsequently emits minimal smoke, thus reducing the risk of significant hazard to life in the event of a fire.

When fire comes into contact with the surface of the EshaFlex 370 FireSafe cap sheet the presence of volcanic rock in the membrane brings about an endothermic reaction. Heat is actually drawn from the flame to support a process of carbonisation in the cap sheet, so reducing the burn temperature. The resulting unbroken carbonised ‘shell’ then seals off combustible material beneath, denying the already-weakened flame further fuel and preventing any further combustion.

EshaFlex 370 FireSafe cap sheet is a torch-applied SBS modified bituminised polyester/fibreglass composite cap sheet with a black mineral finish suitable for all types of roof with a flat or sloped roof construction on new build or refurbishment. Overlaps must be torched.

For all applicable roofing systems contact Radmat Building Products and see BBA certificate No. 15/5282.

Torch applied to base sheet or suitable surface in accordance with the Radmat specification. Overlaps must be torched.

Great Eastern Quays

The former Pharmaceuticals warehouse and offices site around the historic Pump House building is being carefully re-developed in 3 phases to reflect the heritage of the docks at Royal Albert Wharf.

Galliford Try and RMA Architects were appointed by The Notting Hill Housing development on the construction of the site. On completion the project will provide 819 new homes (44% will be affordable housing), a restaurant bar, retail and business space.

Co-existing with the incumbent inhabitants and extending the active dockside, it seeks to create a vibrant commercial core, providing a sustainable development that can produce a sense of community.

Phase 1 was not without its difficulties, located 500 yards from London City Airport’s runway there were constraints and restrictions on height whilst building. Cranes could only be used to a certain height and floodlights could not be used in case they dazzled or confused pilots.

To combat the height restrictions contractors Sureweld developed a hoist system to pull the tons of waterproofing and brown and green roofing materials up on to the roof. Under pressure to meet a tight deadline this meant the roofing contractors could work quickly and efficiently.

Radmat’s PermaQuik PQ6100 Hot Melt Monolithic waterproofing system ensured the 9,500m2 roof was completely watertight, chosen for its durability and lifetime guarantee. ProTherm G XPS X 300 SL insulation was used to comply with the acoustic requirements on balconies and roofs and MedO living roofs system was used to complete the natural green/brown roof solution.

The result is a sustainable and attractive roofing solution and an aesthetically pleasing regeneration project.
