Tightlapper® - One solution for the entire building envelope

Before this range, there were lots of solutions available to installers causing confusion and complexity to the market. The new Tightlapper® range simplifies and provides a more efficient range for installers.

SFS AV-Shaped® Washers - Providing a larger clamping range

The new AV-Shaped® sealing washer is extremely flexible and fully waterproof. Thanks to its geometry and high-quality Ultra Soft EPDM, it covers a huge application area.

On a façade, you will often find different fasteners installed right next to each other. The reason for this is that the clamping ranges are limited, so different fasteners have to be used. The new AV-Shaped® washer increases the clamping range of the fastener, meaning the same fastener can be used for different applications. This enables the design of your building envelope to be uniform and attractive.

The AV-Shaped® sealing washer also compensates for building tolerances whilst remaining 100% waterproof. In addition, the Spin-Free zone and Cut Off thread end, also means security against vibrations and thermal expansion.
