Project name: Hattersley Health Centre
Client: NHS Property Services
Sub contractor: Sanderoof
Solution: BMI Icopal Classic Noxite cap sheet; BMI Profiles Vent XL Underlay; BMI Tapered Thermazone Insulation; BMI TorchSafe Striped VCL / Profiles Vapour Vent XL; SA Primer / Siplast Primer
Hattersley Health centre comprises of seven flat roofs where significant refurbishment was required. The roofing systems were replaced with a BMI Icopal Noxite Classic built up felt system, in which the Noxite capsheet reduces the effects of traffic pollution. All of the works took place whilst the centre remained open to the public so ensuring the building remained watertight throughout was paramount.
The seven roofs for this project were all at differing heights and all needed individually tapered insulation schemes to drain water to the perimeter as the client decided that it did not want to retain the internal drainage outlets. The BMI technical team conducted a laser level survey to determine the best way to achieve this. To accomplish the brief two cut-to-falls systems were in operation. The first to level out six of the seven roofs, while the second system drained to the perimeters.
NHS Property Services is committed to employing sustainable and environmental alternatives wherever practical. The replacement roof for this project is a BMI Icopal Noxite classic built up felt system, in which the Noxite capsheet reduces the effects of traffic pollution. The Noxite® torch-on roofing membrane turns the harmful nitrous oxides produced by traffic into benign nitrates, a depolluting effect that lasts as long as the waterproofing membrane.
To give a sense of the significance of the depollution potential of this eco-technology, a 1,000m² Noxite roof could purify as much NOx from the air as produced by an average car travelling 10,000 miles every year. That’s equivalent to travelling from London to Edinburgh and back 15 times.
