HEINZMANN windows and doors are made of solid vinyl and are operated with a single handle. By turning the handle, you can operate the window in two separate modes: the turn mode (swing mode) for easy cleaning, and the tilt mode (inward mode) for ventilation. Steel reinforcement profiles ensure stable and reliable function. Multi-chambers, in both the frame and sash profile, can be clearly distinguished. Each of the chambers have their own micro climate, capable of insulating even big temperature differences between inside and out. HEINZMANN windows and doors exceed the highest industrial standards, making them ideal for residential and commercial buildings. • Custom Made Superior Design • High Performance Security & Safety • Maximum Energy Efficiency - Reduces Outside Noise Levels
