Concrete window sill

Concrete window sills as a decorative element in modern living areas

Are you a private builder and currently creating a modern new home for yourself and your loved ones or would you like to adapt your outdated old flat to modern living requirements?

Then, of course, a chic interior window sill made of high-quality concrete is a must, because window sills are not just functional today, but also have a decorative effect that should not be underestimated in times of open window areas and large panoramic windows! Especially if concrete elements have already been used in the interior design, but this is not a requirement, as a concrete window sill is so straightforward and discreet that it fits in with any interior design style.

For a long time, window sills made of plastic, natural stone, wood or aluminium were modern. Now concrete is also playing an increasingly prominent role in interior design. There are many reasons for this, but the natural, harmonious and understated appearance of an interior window sill made of concrete should be emphasised. It is simply beautiful and pleases the heart and eye of the modern, discerning minimalist.

High-quality concrete interior window sill for large and small windows

The silky-soft, smooth concrete surface of your lovingly handcrafted favourite accessory is of a particularly high quality. Small pits or sometimes even shading give the concrete window sill that certain something...in a way a kind of artistic effect and make every window sill unique (sometimes more and sometimes less intense, but always very subtle and always beautiful. See for yourself and share our enthusiasm for modern window sills made of high-quality concrete. In our (admittedly very biased) eyes, there is no better window sill solution.

Customised production made in Germany

Another advantage of a window sill from CO33 is that it is customised in our factory in Rudolstadt. You can choose from 2 concrete colours (concrete grey or dark grey), but a subsequent colour of your choice is also possible with concrete window sills and makes them particularly resistant to soiling under heavy use. Our window sills are impregnated as standard.

For the dimensions, we provide several options for the window sill depth and material thickness and you only need to specify the desired length (maximum 2.0 m) and the required number of pieces. For window sills > 2.0 m, we recommend a central division.
(Example: window sill dimension: 3.0 m = 2 units of 1.50 m each).
Subsequent size adjustments to the window sills on site are no longer necessary. Simply insert the window sill and enjoy the view ;).

Easy to clean and hard-wearing

The easy maintenance of your concrete window sill is also an unbeatable argument. Simply wipe with a dry or damp cloth and make sure that no water collects under any existing pots, which is particularly the case with clay pots or if water is spilt when watering. In this case, simply use a saucer...perhaps one made of concrete ;)...

We would be delighted if you decide in favour of a CO33 window sill and will be happy to answer any further questions you may have, for example about outdoor use or production in special sizes.
