Designed to be installed on the inside of the window. The widths of the sills being offered are from 15 to 35 cm. The window sills have been extruded from the primary material like the profiles for the windows. Also, when combining the non-laminated sills with the white profiles, no practical difference is noticeable between the color nuances. We achieve equal vision of the sill and of the window, and we obtain completion and style for the entire interior.
