Selection of rollet profile nominal size
Resistance to wind pressure
Selection of rollet profile nominal size made on basis of aperture size and wind district in which project is placed.
In different regions force of wind differs — from light wind to powerful hurricane. Broken tree branches or other items picked up with strong wind can easily break glass in windows or doors.
Rollet systems — reliable modern security measeure against nature and bad weather.
It is very important to choose correct rollet profile. Rollet should not only protect windows but also resist in front of nature.
All rollets of Stekloplast tested on resistance to wind pressure in accordance to construction norms and regulations 2.01.07 and EN13659.
Rollets may be installed on apertures with width up to 5,5 m and area up to 14 sq.m. (depending on profile nominal size and wind district).Define your wind district
