A roof light is exposed to wind and snow loads, which fully depend on the design of the actual project as well as its location. In coastal areas and on flat, open land, you often see significant wind loads. In Norway, Sweden and Finland or in mountainous areas you often find significant snow loads compared with other parts of Europe. For each individual project Vitral’s project managers make static calculations to ensure a sufficiently strong and water tight solution under all weather conditions. The calculation is also made for optimization of panel sizes and choice of glass specifications in order that the final solution becomes as cost effective as possible.
