Aluplast uPVC casement windows achieve u-values as low as 1.2W/m²K and carry a WER A+ rating. That means lower energy bills for your customers, easier compliance with building regulations and a product that sells itself on performance.
With a five-chamber 70mm profile and compatibility with triple glazed units, these windows deliver thermal efficiency that is hard to match at this price point.
With two core casement systems — the fully sculptured Ideal 70 and the contemporary Ideal 4000 SquareLine — plus a flush sash option compatible with both, the Aluplast casement range gives you the flexibility to specify the right window for any project.
