Unrivalled versatility, exceptional performance

The beauty of casement windows is their versatility; they’re suitable for use in virtually any type of project. Constructed from either aluminium or PVCu, our casements can be hung from the top and side. They’re also suitable for open out, top swing reversible and parallel operations. Because they come with a 10-year, FENSA backed guarantee, they’re also guaranteed to last.

Manufactured by the expert West-End Windows team in our advanced facility, the levels of performance across our whole range are exceptional. Weatherproof and highly secure, our casement windows insulate properties extremely well, allowing for the creation of quiet, comfortable environments. They’re able to be double or triple glazed, depending on specific project requirements.

A profile suited to every project

We use the full Alitherm profile range from Smart Systems for our aluminium casement windows. They utilise polyamide thermal breaks, ensuring for an advanced thermal performance. Easily achieving PAS24:2012, they meet all required standards for security too. Plus, each system meets the strict requirements of Document L 2010, as well as BS6375, ensuring for a highly-durable, fully weathertight system.

Our PVCu casements are manufactured from a variety of profiles. Each of these profiles are multi-chambered, meaning they trap significantly more heat inside properties. A range of chamfered or sculptured profiles are available, to suit the unique requirements of different projects. Regardless, a visually appealing window is assured. They come with a full range of customisable hardware, including Astragal and Georgian bars, mock horns, fire escape stays, integral blinds, monkey tail handles and slot vents.
