Benefits
Windows and doors in the BRONZE range ensure efficiency due to their structural profile, featuring a construction depth of 74 mm and 5/6-chamber insulation. Structural rigidity is guaranteed by reinforcements with a thickness of 1.5–2 mm.

Innovations
Through UTEC GlassFix, the glass becomes an active structural element, bonded to the sash with an insulating double-sided adhesive tape that enhances stability and reduces energy loss. The elimination of frame tension and the reduction of vibrations lead to superior thermal and acoustic insulation, because true innovation strengthens performance from within, providing safer and more efficient windows.
The hardware is the set of metallic mechanisms installed within the PVC joinery (windows and doors), which allows for opening, closing, and secure locking. Although often invisible, the hardware is the key component regarding:
- The correct and secure operation of the joinery
- Residential anti-theft protection
- Long-term wear resistance
Discover all the ways you can customize your window openings. From fixed windows to the possibility of having micro-ventilation and tilt positions.
An insulating glass unit (IGU) is an assembly made of two or three glass panes separated by a gas-filled space, measured in millimeters, and held apart by a warm-edge spacer bar provided with sealants.
Colours
Windows integrate perfectly into your home’s design thanks to a wide range of colors. They add an extra touch of personality due to the dual-color configuration (exterior/interior) included as standard. This solution allows for a color mix that fits both the minimalist exterior style and your desired interior design.
