External Window Sills

External window sills made of metal can complement all types of windows, regardless of the material they are made of. When deciding on such products, we will have to make a key decision: choose those made of steel or aluminum.

Aluminum window sills, due to their thickness, show greater stiffness and resistance to damage than steel window sills almost three times thinner. In addition, aluminum resists corrosion better than steel, although both materials resist moisture.

Our sales department will be happy to help you choose the right solution and tell you what will be the right choice for you when it comes to external window sills.


Steel external window sills are the most popular group of window sills, external metal window sills are perfect for changing weather conditions that occur in our climate. The highest quality of the steel with a thickness of 0.75 mm guarantees their durability and long-term use.

The steel window sills we offer are thoroughly protected against moisture and rust. Bearing in mind the aesthetic appearance of the windows, all external steel window sills are powder coated in several colors to choose from. Thanks to this simple procedure, the window sills blend in perfectly with the facades of utility buildings, apartment blocks or single-family houses.

Granite – since the dawn of history, this material has been used as building, decorative and sculptural stone.

Nowadays, we also use it as an external window sill, kitchen countertop, stair step, tombstone, bathroom countertop, etc. Granite belongs to the group of solid igneous rocks, thanks to which it is extremely resistant to all kinds of damage caused by abrasion and friction, therefore it is ideal for floors with high pedestrian traffic.

Neutral PH makes external granite window sills very popular in public facilities (hospitals, clinics, swimming pools) and the ease of keeping clean on large flat surfaces is a very desirable feature.

Window sills made of good granite are the perfect complement to the window joinery from the outside of the building. Affordable price, beautiful colors and a unique appearance will emphasize the uniqueness of the building.
