Exceptional Performance

Our Casement windows excel in both appearance and performance, manufactured from the highest quality materials they provide exceptional acoustic and thermal performance.

With triple glazing, aluminium cladding and triple gasket configuration our windows are one of the few certified as truly passive house compliant by the German institute of passive technologies.

Quality Materials

As standard our casement windows are manufactured from sustainably sourced slow grown engineered Scandinavian spruce, an exceptional material recognised for both stability and longevity. Once processed our timber is treated with a water based anti-fungal preservative and base coat prior to being finished with a high quality microporous colour or stain of your choice, and all at no extra cost. Of course, should you prefer an alternative timber we offer a wide range, the choice is alway yours.

Opening Options

We offer side-hung, side projection, or top hung with optional reversible easy clean. All manufactured using the highest quality fittings and hardware from manufacturers such as ROTO, a company with many years experience and an enviable reputation for quality.


Secure by design, as standard our windows are fitted with high quality Espagnolette fasteners which provide multiple locking points around the frame. We also offer safety glass and key lock handles if you require PASS24 compliance for new build installations.
