Low Emissivity (LE)
For maximum energy efficiency
Alternative composite profiles
- The GUTMANN GWD 080 window system offers alternative composite profiles for frames, sashes and glazing bars with an optimized composite bar. LE films (low emissivity) in the area of the web flags ensure a significant reduction in heat radiation and therefore outstanding energy efficiency.
- Efficiency through innovation: The LE film minimizes energy loss and supports both thermal insulation in winter and protection against overheating in summer.
- Flexible profile design: The frame profiles can be designed with face widths from 26 to 52 mm and the sash profiles from 50 to 59 mm – ideal for a wide range of modern building projects.
