Product and Services

Years of our customers’ feedback and advances in technology have helped us develop our bespoke 50-Year casement window into one of the highest performing on the market. While we wanted to make our windows very thermally efficient, we also wanted to stay true to the heritage the casement window has. That’s why we designed our range paying the closest detail to retain the flush-line traditional appearance that helps add character to your property.

London Box Sash Windows provides a range of bespoke casement window options to suit your specific requirements. From traditional flush casement windows all the way through to bespoke modern designs.

Like all our premium specification products, the ‘50-Year Casement Window’ is made using the highest grade Accoya® wood on the market. Accoya® wood is the result of decades of research and development that has brought together a long-established, extensively proven wood modification technique and leading-edge patented technology – acetylation – to create a high performance wood, ideal for outdoor use and challenging applications.Accoya® has properties that match or exceed those of the best tropical hardwoods and treated woods, yet is manufactured using wood from sustainable sources.
