Sarah Hanlon, marketing manager at Marley Eternit, said: “Despite the availability of information on the internet, our study shows that the industry still values trade manuals, but worryingly, many are still using out-of- date product guides when sourcing and specifying.

Nails for Flat Roofs New from Ancon Building Products, the ‘Staifix Super-8’ is a headed helical nail for fixing flat, warm roofs. It is hammered through plywood/insulation composite panels and embeds into the timber joist below to provide a fast, secure fixing. The Super-8 is manufactured in three standard lengths (135, 165, 195mm) to suit panel depths from 70mm to 156mm, and is available in bags of 25 or boxes of 500. Unlike traditional nails, helical nails rotate as they are driven in, inducing a self-tapping action and consequently do not split timbers or compress the layer of insulation.

Energy-Saving Rooflights
When specifying a rooflight system, the Twinfix Multi-Link- Panel ticks all the boxes for sustainability. They consist of a powder coated aluminium frame glazed with virtually unbreakable multiwall polycarbonate, both of which can be recycled at the end of their life span. 25mm multiwall polycarbonate has a great light transmission and is opaque to infra red. This results in infra-red heat being retained inside a building, helping to cut down on energy usage/costs. Individual panels can span 4000mm at 1250mm centres, which means less glazing bars, more natural light ingress and reduced energy usage/costs.

Profile 6 to the rescue Hanson, recently specified Marley Eternit Profile 6 sheets for its new £49m ‘super’ brick factory in Measham, Leicestershire. Profile 6 was specified for the roof and cladding because it is a high strength fibre cement sheet that is unaffected by the humid and aggressive environments found in this type of plant. The sheets are able to withstand the 600 to 1000ºC temperatures of the kilns and acidic atmosphere created by sulphur released from the clay during the brick making process. Profile 6 sheets, although watertight, are vapour permeable, which significantly reduces the occurrence of this condensation.
Nu-lok’s roofing system selected for prestigious
racing stables in Cheshire Nu-lok’s unique roofing system has been installed at a new racing yard in Cheshire.
David Halford of KWA
Architects explained: “The design had natural slates to comply with planning requirements. On some buildings these were fixed over timber trusses and on others over Kingspan TS panels. We ensured Nu-lok was suitable for all these applications and roof forms before specifying their system. We were also considering traditional battens and slates for the stables’ roof, but opted for Nu-lok’s system due to the significant saving in the number of slates required.”
