105 UPVC/Vinyl Grill Design Fixed Windows

Introduction：

The 105 Series uPVC Fixed Windows are designed to maximize natural light while delivering excellent thermal performance for energy-conscious buildings. The non-operable design minimizes air leakage and supports superior insulation efficiency.

Constructed with a reinforced multi-chamber uPVC profile, the window achieves a U-value below 1.2, meeting the demands of colder and mixed climate zones in the North American market. The integrated flanged design simplifies installation and enhances long-term air and water tightness, allowing seamless integration with operable window systems.
