This project was a new development of six town houses on Church Road in Crystal Palace, London.
The six buildings off invert construction roof were weathered using Eternite fibre cement slates, fitted to pre insulated Kingspan panels. These panels were craned to roof level and mechanically fixed to perlins.
Once each slope was completed, the breather membrane, which had been pre-fitted to the panels, formed a water tight pitched roof. A timber framed, WPB ply box gutter, was then constructed between the sloping roofs. This in-turn was weathered using VET Evalon single ply membrane, fully bonded to gutter sole and lay boards. This process was fast tracked and each roof was watertight within two working days of the roof panels being fitted.
Zinc box gutters were fabricated on site and fitted to the end dwellings. All roofs were fitted with Velux roof lights and once the slating was completed, Photovoltaic (PV) electricity generating units were fitted to the pitched roof.
Once the external cladding to the building was completed, powder coated aluminium flashings were fitted to weather the apex and square section powder coated aluminium hopper heads and down pipes we’re fitted. Roofs to the front elevation bin stores were weathered in VET Evalon single ply membrane, with powder coated aluminium flashings fitted to the perimeter.
