White PVC Energy-Efficient Window Frame 1400x900mm Low U-Value Design

Description

• Engineered with a low U-value frame design incorporating thermal break chambers and multi-seal technology to reduce heat loss through the window perimeter in both new construction and replacement applications.
• Six-chamber PVC profile with a 76mm frame depth provides extended thermal paths that slow heat conduction between interior and exterior surfaces of the frame.
• Warm-edge spacer channel integrated into the glazing rebate reduces condensation risk at the glass edge, maintaining clear sightlines and protecting surrounding finishes from moisture damage.
• Compatible with a range of double and triple-glazed units from 24mm to 40mm, offering flexibility to match the glazing specification to the project requirements.
• Smooth white exterior finish with integrated UV inhibitors maintains colour consistency and surface integrity under prolonged sun exposure without painting or refinishing.
