Premier Timber

Windows & Doors

Westbury Windows & Joinery are a specialist timber window and door manufacturer based in Essex supplying across the UK. All our products are made-to-order from timber sash windows, timber casements and timber doors for both new build and refurbishment projects.

Because of Westbury’s passion and enthusiasm for the aesthetics and performance of our glazed garden rooms, we were continually asked to offer a range of timber windows and timber doors. What makes Westbury’s joinery special is we do not opt-out of the detail for ease and speed of manufacture, as do many of UK manufactures. With our modern machinery we create flush joints, sharp edges and traditional mouldings that we have seen being washed away by many of our contemporaries. Here, these are considered to be essential elements of our British architectural heritage not to be forgotten.

Each item whether a timber sash window, a casement window or a french door is manufactured with the same care, detail, timber, paints and ironmongery as with our garden rooms. This is what makes our product so good and so unique!

Our window materials are specially selected to ensure both durability and stability; guaranteed not to rot, expand or shrink. Ensuring longevity and delivering a product that is more environmentally-sound is our aim.

Roof lanterns

Westbury Roof Lanterns are structural masterpieces. Clean lines and symmetry create incredible architectural impact when viewed from inside and out. Our Lanterns are designed with correct proportion with consideration being given to depth of shelf, beam dimension and hip shape. The result is an impressive, balanced design.

We support architects and contractors with a full in-house design service which includes detailed working drawings and 1:20 kerb detail drawings for site.

Seeking Sustainability with Accoya

We love building garden rooms because we love nature. We love the sense of wellbeing that inviting the great outdoors into your home can bring. So we’d be hypocrites if we didn’t consider the effect that the timber product manufacturing industry can have on the natural environment, and make responsible decisions with that in mind.
