Description
Made-to-Measure Twin-Vent Central Core Rosewood uPVC Casement Windows
Achieve maximum structural ventilation flexibility, clean symmetry, and advanced energy efficiency with our custom-manufactured rosewood uPVC window. Built to your precise millimeter requirements, this distinctive 3-light frame format is ideal for master bedrooms, large kitchens, and central living areas where high-capacity, multi-level airflow options are required without sacrificing wide-angle viewing areas.
This versatile configuration stands out within our uPVC casement windows collection. By equipping the central column with two independent active openers, you gain complete seasonal control over your home’s climate. Open the upper top-hung awning sash for micro-ventilation during light rainfall, or throw open the large side-hung lower sash to rapidly flush hot air and increase circulation. The flanking full-height fixed lights maintain ultra-slim sightlines, bathing your property in unobstructed natural light.
Advanced Multi-Chamber Insulation & Structural Property Defense
Constructed using a high-spec 70mm fully sculptured multi-chambered profile system, this wide window variant handles broad openings 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.
