Watertight and low-maintenance threshold systems

Threshold systems from Holonite fit seamlessly with wood (Premax®), plastic (Kumax®) and aluminium frames and are supplied with sealing collars and mounting screws along with accompanying frame plugs. Holonite is committed to maintaining the highest level of quality among its threshold systems and is able to guarantee this through cooperation with partners which have expertise in making wood, plastic and aluminium frames wind-proof and watertight during renovation and construction projects.

As with all other Holonite products, the various thresholds systems meet the requirements set out in the Dutch Buildings Decree, the DUBO sustainable building regulations and the Building Materials Decree. All Holonite products are made from composite stone and inhibit the creation of thermal bridges.
