A specifier's guide to fasteners and fixings

摘要

Specifying fasteners and fixings correctly the first-time round is critical in ensuring the fastening system remains robust throughout the lifetime of the roofing system or building envelope. However, fasteners are often not specified until Stage 4 in the RIBA plan of work - when the fastening system has already been determined. It's often up to contractors to price the work, and they can end up cutting corners with the fasteners and fixings. By engaging higher up in the build process chain, the correct fasten- ers are matched to perform with the fastening system and the material it is securing, as well as the substrate that the fastener is securing down to -improving the total cost of ownership and efficiency of the system.
