Ultra Electronics, Greenford, London

Ultra Electronics was a total refurbishment of the existing asbestos and flat roofs, gutters and vertical cladding. The project was to make a very old tired looking building with many damp and water ingress issues watertight and more appealing to the eye.

The asbestos roof was oversheeted with a 0.7 gauge profiled plastisol coated metal roof sheet complete with AshGrid bar system, 200mm Rockwool insulation and new skylights.

The existing asphalt flat roofs were cleaned, primed with bitumen primer and covered with a vapour barrier felt, 4mm base layer torch on felt and a 4mm mineral tweed coloured torch on cap sheet complete with all welts, drips and closures. All gutters were lined with a Plygene gutter liner system complete with new outlets and weir chutes to the ends.

Vertical cladding was installed to the exterior of the building which was a mix of Kingspan composite Microrib cladding panels, metal single skin profiled plastisol coated cladding sheets complete with Rockwool insulation and various purpose made flashings and sill flashings to give a desired effect to the building.
