TEROSON has been a specialist in sealing and adhesive solutions for façades and windows for over 30 years. With TEROSON FO X, Henkel presents an innovative window sealing tape specifically tailored to meet the unique requirements of timber and modular construction. Moisture protection and effective moisture management are the focus – to prevent damage such as rot and to ensure a residual moisture content of no more than 20%, in full compliance with DIN 4108-3. Thanks to its low weight, timber also enables vertical extensions in commercial and multi-storey construction where structural limitations must be considered. TEROSON FO X offers maximum safety and universal adhesion on a wide range of substrates, including timber, aluminium, PVC, and concrete – even under extreme climatic conditions.
The TEROSON FO X window sealing tape is a moisture-adaptive, multifunctional solution that automatically adjusts to changing climatic conditions. Thanks to its flexible membrane structure, the tape responds to temperature and humidity fluctuations by opening or closing its pores accordingly. This ensures a consistently optimal water vapor diffusion performance – precisely aligned with the requirements of DIN 4108-3 for timber construction. Whether for frame or structural connections, or in combination with moisture-variable surface sealing membranes (housewrapping), TEROSON FO X provides safety and maximum adaptability in all areas – even under extreme climatic conditions.
