uPVC Casement Window C70
High-quality uPVC C70 casement windows offering excellent insulation, security, and a clean modern finish. Durable, low-maintenance, and energy efficient.
uPVC C70 casement windows are a versatile and reliable choice for both modern and traditional properties. Designed to open outward on side hinges, they provide excellent ventilation, clear sightlines, and a timeless appearance that suits a wide range of residential and commercial buildings.
Built using the C70 profile system, these windows deliver strong thermal performance and long-term durability. The multi-chambered uPVC frame combined with double-glazed units helps reduce heat loss, minimise draughts, and improve overall energy efficiency, contributing to lower heating costs throughout the year.
Security is a key feature of uPVC C70 casement windows, with reinforced frames, modern locking mechanisms, and high-performance glazing options available. Unlike timber alternatives, uPVC requires very little maintenance — it won’t rot, warp, or need repainting, making it a cost-effective and low-maintenance solution.
Available in a range of colours, finishes, and configurations, uPVC C70 casement windows can be tailored to suit any architectural style while delivering reliable performance, comfort, and peace of mind.
