Description
Made-to-Measure Asymmetric Transom Opening Rosewood uPVC Casement Windows
Implement tailored architectural styling, smart airflow control, and elite thermal management with our bespoke rosewood uPVC window. Custom-manufactured to your exact millimeter dimensions, this asymmetric dual-light configuration is engineered for secondary bedrooms, kitchens, and hallways where space requires a clever balance between unobstructed viewing glass and single-point weather-protected ventilation.
This functional layout offers a distinct variation within our uPVC casement windows portfolio. By dividing the opening mechanism horizontally on the left side only, you gain a lower top-hung awning vent that drives fresh air inward while remaining protected from light rainfall. The right side features a commanding, full-height fixed pane to maximize natural sunlight, providing a secure, energy-efficient boundary.
Multi-Chamber Insulation & Structural Property Defense
Manufactured from a high-spec 70mm fully sculptured profile system, this window handles seasonal temperature shifts effortlessly via integrated internal air chambers. These pockets break the transfer of cold air from the outside, cooperating with advanced double-glazing technology to optimize your home’s microclimate.
-
Glazing Efficiency: Engineered with 28mm soft-coat Low-E double glazed uPVC windows units, insulated with compressed Argon gas and isolated by a warm-edge spacer bar to maintain interior surface temperatures.
-
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.
