Polinet Roof Windows, which can be easily integrated with all Polinet roof products and systems with mounting accessories, have sealing properties against heat, wind and water thanks to their specially designed heat-insulated profile and body structure consisting of Thermolux polycarbonate products. They meet with electric opener mechanisms that can be controlled for multi-use purposes. Electric opener mechanisms are 24 volt or 230 volt power source and are of two types as rod or chain. Chain opening mechanisms are mostly used in facade windows. Smoke, rain and wind sensors are optionally available in this system. Multifunctional control units can be easily integrated into the general fire alarm system.
