Sills from BB fiberbeton can give the building’s facade a coherent architectural impression with the transition between window and facade. Our GRC sills are produced with many different cross-sections according to the project. Your choice of cross-section depends on the project, number of units, variants, and desired detailed.
Sills can help emphasise the craftmanship of the building’s facade and if you wish to highlight the windows this can be achieved by installing sills with decorative elements.
GRC sills are a technically and economically a good solution with a durability of more than 100 years and a resistance to all weather conditions. Furthermore, GRC does not rot, dent, nor burn and it requires no technical maintenance. We have no standard solutions for sills and all projects are solved individually.
