Oak Sash Company manufactures double-glazed timber windows and doors for homeowners and the trade.

We supply beautifully made, factory painted, bespoke products, which are energy efficient, secure, durable and elegant.

​

All our products are made from FSC-certified, engineered timber, which is treated against rot and fungi, and factory finished with micro-porous, water-based paint in any RAL colour. Window furniture is supplied by major UK manufacturers.

​

By choosing our products you can improve the energy ratings and security of your home.

Our sales team can advise on options including horns, flush vents, double-glazing formats, extended sills, glazing bar design, glass type and additional security.

​

All our products are delivered fully finished, glazed, painted and complete with factory fitted ironmongery and locks. This means there are no extra costs, such as painting and carpentry associated with the on-site joinery model, which can often add 30-40% to the initial expense.
