The new range of TUF-S rivets from fastening systems manufacturer SFS makes installing Cembrit fibre cement rainscreen panels as thin as 8mm using mechanical secret fixings quicker, easier and safer.
Extensive testing by SFS demonstrated how TUF-S challenges the convention that installers need to use different fasteners for different panel materials and thicknesses. Until now, no other rivet of this kind has provided a reliable secret fix for panels manufactured in both HPL and fibre cement.
The TUF-S range is designed to eliminate the risk of overtightening which can ruin the aesthetics of a façade and result in very costly damage.
It consists of nine variants of A4 stainless steel fixings, with a carbon steel mandrel, that can be used to secure a range of panel thicknesses to the rainscreen support clips using the GESIPA Powerbird Pro tool.
The performance of TUF-S for 8mm Cembrit panels was proven by SFS through a series of load tests conducted in its laboratory in Switzerland. This allowed for a set of technical values to be calculated to enable façade engineers to easily determine the number of fasteners and clips required to accommodate different locations, wind loadings, etc.
Installation of TUF-S requires just a standard hole, with no need for complex undercutting – this provides the installer with the flexibility to drill new holes on site if required to accommodate unforeseen issues. The rivet also eliminates the risk of overtorquing, which can damage the rainscreen panels, and it has high pull-out values with no unwinding and uninstallation possible via a hex head.
Ged Ferris, Cembrit UK Marketing Manager: “We are pleased that SFS have developed an innovative mechanical secret fix system for use with the standard 8mm thick rainscreen cladding boards. Designed and tested by SFS for use with fibre cement cladding, the combination of SFS rear rivets and Cembrit boards creates an attractive façade, uninterrupted by visible fixings that will appeal to rainscreen cladding specifiers throughout the British Isles. SFS have proven the rivet’s effectiveness in the clearest terms through their extensive testing and this gives us complete confidence in recommending the fastener’s use in any Cembrit rainscreen applications in the UK.”
Andy Stolworthy, Director of Product & Market Development at SFS: “We’re delighted to have worked closely with Cembrit to provide them with a highly effective secret fix solution that will work across their different rainscreen panels. This development project is an excellent example of how SFS is able to create products with innovative unique features that provide OEMs with the assurances they need and address the most common issues faced by installers.”
