Installing Cembrit fibre cement rainscreen panels as thin as 8mm using mechanical secret fixings just became quicker, easier and safer thanks to the innovative new range of TUF-S rivets by the world’s leading fastening systems manufacturer SFS.

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.

Cembrit copyThe 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 rivet’s design provides a wide range of installation benefits to save time and money, and deliver a safer, better quality overall result.

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. This provided Cembrit with total assurance according to Ged Ferris, Cembrit UK Marketing Manager:

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.”

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.

Andy Stolworthy, Director of Product & Market Development at SFS says: “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.”
