This flat window sill with a 110×20 upstand and a thickness of 6 cm is the ideal choice for finishing your facade with durable Belgian blue stone. The sill features a blue-sanded finish that not only gives it a timeless appearance, but also provides extra traction and an elegant, modern look.
Thanks to the integrated 0.6 × 0.6 cm drainage groove located 2 cm from the front edge, rainwater is efficiently drained away, keeping walls protected from dirt and moisture. The drainage groove ends neatly 2 cm from the finished edges, ensuring an aesthetic and functional finish. The raised edge at the back provides additional protection against water intrusion, helping your window frames and facade stay looking their best for longer.
With its sturdy 6-cm thickness, this window sill can withstand heavy use and extreme weather conditions. Its flat design ensures a seamless integration into both modern and classic facades.

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 window sills with a raised edge, 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.
