This Flat door threshold with an upstand measuring 110×20 With a thickness of 6 cm, it combines sturdiness with a refined finish. Crafted from Belgian blue stone sourced from our own Belgian quarry and featuring a blue-honed top layer, this is a durable and stylish choice for both renovation and new construction.
The threshold is equipped with a discreet drainage groove measuring 0.6 × 0.6 cm, located 2 cm from the front edge. This groove ends neatly 2 cm from the machined ends, ensuring optimal water drainage and protecting the doorway from moisture and dirt. Thanks to the upstand, the threshold also gains an additional barrier against water seepage, which helps extend the service life of both the threshold and the surrounding structure.
With its sturdy 6 cm thickness, this threshold is ideal for high-traffic hallways, doors, and sliding windows. Its flat design and smooth-sanded finish give the threshold a modern look that complements any architectural style, from classic to contemporary.

This stock version measures 110 × 20 cm. The specified total height is 6 cm (5 cm stone + 1 cm upstand); for a threshold with an upstand, the back side is therefore higher than the actual walking surface or top surface.
The upstand forms a raised edge at the rear that helps ensure a proper seal against the window or door frame and the waterproofing barrier. Proper detailing always depends on the wall construction and the window or door profile.
Yes. It is Belgian blue stone, a natural stone in which natural fossils, veins, and slight variations in color are common.
Yes. Renier also offers custom-made door thresholds with an upstand, so that the length, width, height, and finish can be tailored to the project.
Ensure that the subfloor is stable and fully load-bearing, and that it connects properly to the waterproofing and trim. If in doubt, it’s best to have the contractor or architect review the details.
