What Is a timber casement window?
Casement windows are hinged timber windows that can open from the side or the top. Our designs include single, double and triple casement configurations, with optional fanlights and glazing bars.
Flush casement windows sit level with the frame for a traditional look, while stormproof casements have a slight overlap to improve weatherproofing. We’ll help you choose the right style for your home.
Timber choices & finishes for quality and longevity
Select from a wide range of sustainably sourced hardwoods and softwoods. Our team can provide samples to help you decide and advise on stains, paints or micro‑porous coatings that protect against moisture while letting the timber breathe. All timber is FSC® certified, ensuring your windows are beautiful, durable and environmentally responsible.
Quality timber windows are an investment, and while uPVC alternatives may seem cheaper, well‑maintained wooden windows can last from 20 – 40 years. Timber’s natural strength means your windows will remain stable, attractive and weatherproof for decades, saving you money over their lifetime.
Colours to match your personal style
We spray finish your casement windows using Teknos paint which can be colour matched to many popular paint brands. This creates the perfect finish to completment your home’s style and surroundings.
