Fasatan® and Fasatyl®

EPDM foils for sealing structures and the building base

Product Group

EPDM foils from the BOSIG Fasatan / Fasatyl® product series are used for sealing buildings and the base of buildings, such as curtain walls, rear-ventilated façade or as additional sealing under the window sill, in timber construction and for threshold sealing.

Particularly in the area of threshold waterproofing, our Fasatan® is the only* EPDM waterproofing membrane that exceeds the requirements of DIN 18533 with a thickness of just 0.8 mm.

*as of 02/2020

For optimum and safe processing on site, we supply foils with one or more tailor-made adhesive strips. BOSIG offers a time-saving weatherstrip solution for common façade systems.
