Description
Made-to-Measure 3-Light Multi-Opening Rosewood uPVC Casement Windows
Introduce architectural symmetry, expansive ventilation options, and elite thermal defense to your home with our bespoke rosewood uPVC window. Precision-manufactured to order, Style 31 offers a multi-functional triple-pane layout designed for wide window openings in main lounges, front elevations, and master bedrooms where balanced ventilation and panoramic views are vital.
As a highly versatile option within our high-performance uPVC casement windows catalog, this style features a mirrored opening layout. The left and right lights contain a top-hung transom vent over a side-hung opening casement for maximum airflow control. These flank a completely fixed central picture light that captures uninterrupted natural light, giving you a secure, weather-tight boundary.
Multi-Chamber Insulation & Advanced Property Defense
Manufactured using a high-density 70mm fully sculptured profile system, this wide-span window uses integrated internal air chambers to form a robust thermal break. This breaks down the movement of cold air from the outside, working alongside advanced double glazing to optimize indoor comfort.
-
Glazing Engineering: Equipped with 28mm soft-coat Low-E double glazed uPVC windows units, filled with insulating Argon gas and separated by a black warm-edge spacer bar to completely stop cold bridging.
-
Security Architecture: Fitted with secure internal glazing beads to eliminate external glass removal, combined with heavy-duty multi-point locking mechanisms that anchor all four operable sashes tightly into the frame.
-
Weatherproof Sealing: Patented double-action ‘bubble’ gaskets form a resilient, compression seal, ensuring the frame remains entirely immune to draughts, rot, or fading under extreme weather.
