Profile 6 fibre cement sheeting
Profile 6 roofing and cladding from Marley Eternit was used in the creation of one of the largest custom build, affordable housing projects in the UK.
Backed by the Homes & Communities Agency, the housing project delivered around 150 new houses to one of Cornwall's most deprived areas. It is part of a wider Heartlands development to regenerate the Pool-Camborne-Redruth corrider, which had been largely untouched after the demise of the tin mining industry and closure of the mines in 1998.
Given the project's location within a World Heritage Site, the local planning authority had issued a very strict design and products brief. Materials and finishes were to resonate with the mining heritage as well as harmonise with the agricultural buildings on the surrounding landscape.
For the roofs and the vertical cladding on the houses, the architects required a product that would coordinate with the dark anthracite metal sheet cladding on the flat apartment buildings, as well as blend with the roofs of the recently renovated Mining Museum. The product also needed to meet the tight budget parameters of this affordable housing scheme.
The Profile 6 sheeting was specified with a black finish, which gives a very distinct look to the properties and ensured that the buildings subtly referenced the area's mining history.
For the builder, Marley Eternit’s Profile 6 sheeting ticked a number of key technical boxes. As a high-strength fibre cement sheet, reinforced with polypropylene strips at precisely engineered locations that run along the length of the sheet, it provided maximum impact strength and excellent durability. Designed for roofs of 5 degree pitch and above, Profile 6 was an ideal sheeting for the 45 degree pitched roofs of the properties. The same product could also be used for the vertical wall skins, thereby ensuring materials compatibility. It was also quick and easy to install, which was important for this “pre-fabricated” type of house.
A further advantage of the Profile 6 sheeting for both the architect and builder was that it provided excellent thermal insualtion whilst being minimally affected by the Cornish climate. Its lack of metallic content means there will be no rust, no rot and no corrosion, ensuring the homes will retain their unique appearance in years to come.
