Description
Made-to-Measure Central Transom Vent Rosewood uPVC Casement Windows
Introduce seamless architectural balance, targeted high-level ventilation, and premium energy efficiency to your property with our custom-built rosewood uPVC window. Tailored precisely to your specific structural dimensions, this symmetrical triple-light configuration is engineered for expansive living spaces, kitchens, and front facades where you want to preserve panoramic views on the sides while maintaining localized airflow in the center.
This practical configuration serves as an excellent addition to our uPVC casement windows range. By placing a top-hung awning sash exclusively in the upper middle segment, rising indoor heat is easily released while keeping rain out. The flanking full-height fixed picture lights flood the room with natural light from multiple angles, maintaining an airtight, ultra-secure perimeter.
Advanced Multi-Chamber Insulation & Structural Property Defense
Crafted from a high-density 70mm fully sculptured frame, this wide three-light window system features integrated internal air pockets that form an efficient thermal break. This stops cold bridging from transferring chilly drafts indoors, working alongside advanced double glazing to optimize your home’s microclimate.
-
Glazing Efficiency: Outfitted with 28mm soft-coat Low-E double glazed uPVC windows units, filled with insulating Argon gas and sealed with a black warm-edge spacer bar to eliminate thermal bridging.
-
Security Integration: Designed with structural internal glazing beads that block external pane extraction, paired with robust multi-point locking systems securing the active lower opening hardware.
-
Weatherproof Sealing: Patented double-action ‘bubble’ gaskets form an airtight compression seal, ensuring the frame remains entirely immune to draughts, moisture ingress, or sun-fading over its lifespan.
