As a result of the significant changes introduced in the new British Standard, we have been working hard to develop products and services to help architects, housebuilders and contractors to meet the new more stringent requirements.
To address the new rules around clipping, we developed SoloFix. The affordable one piece clip and nail made from ZiAl saves up to 30% on clipping time and delivers a high strength, high performance solution, which can be used for all UK exposures.
We put SoloFix to the test on a roof, and found that contractors saved up to 30% on clipping time compared to a traditional two-piece clip. With a degree of clipping now required on most roofs laid in single lap tiles, using SoloFix with its impressive speed of installation will inevitably translate into significant labour savings, especially on larger schemes.
To comply with the mortar changes in BS 5534, almost all projects - excluding heritage sites - should use dry fix as the best alternative to mortar. However, for those roofers who still wish to mortar bed tiles and fittings, we have launched two new fixing kits for the ridge and hip providing a means of providing a compliant means of mechanically fixing through mortar. It’s worth remembering though that often, by the time a mechanical fix is added to mortar bedding, it would have likely been just as quick and cost effective to use a full dry fix system. Dry fix also gives the added benefits of ventilation, improved security and a reduction in ongoing maintenance costs.
Finally, we have also developed a guide to BS 5534 to further help architects, housebuilders and contractors, and also have a suite of technical support services available designed to assist the selection of the right type of fixings for a project. In particular, contractors and specifiers can get hold of a fixing guide based on the geographical location of individual roofing projects by using Marley Eternit’s new Tilefix tool.
BS 5534 will have an impact on roofing programmes, and as always, we’re here to help. If you have any questions or concerns about fixings or how BS 5534 will affect your project please contact us on 01283 722588 or ask us on Twitter @MarleyEternit.
