TRADITIONAL BOX SASH WINDOWS
These are the most traditional box sash windows with a weights system. It is our primary and most recommended product for those who desire simple construction yet a great design.
Cords and weights are the traditional forms in which timber box sash windows operate. The mechanism works by counterbalancing the weight of the window with a lead (iron) bar attached to a chord that rolls over a pulley. This enables the sash window to slide up and down with relative ease. A significant advantage of these windows is that they provide efficient cooling of interiors during warm weather. Opening both the top and bottom of a sash window by equal amounts allows warm air at the top of the room to escape while letting in the cool air from outside into the room through the bottom opening.
Our box sash windows have been carefully designed to ensure that frames, meetings rails and glazing bars reproduce the traditional form as closely as possible. You can get the look of an authentic timber box sash with all the modern benefits. Our timber double-glazed sash windows are secure, rattle-free, and energy efficient.
We operate a nationwide service and will never turn down enquiries from the whole of the UK. But as our office is located in South East London, we attract enquiries from surrounding areas, where we not just supply but also install our traditional box sash windows (London, Kent, Sussex, Surrey, Essex etc.).

SASH LIFTS & PULLS
The finish of your timber box sash windows can harmonise with the design of the room. There are three coating options available – oil, paint, and clear- revealing the texture of the wood.
We use Teknos paints which are exceptionally durable – because they do not change colour under weather conditions. Our range of paint colours is based on the RAL palette and enables us to offer almost a limitless choice of finishes. Furthermore, we offer dual colour painting.

Ranebrook seem to have all of the answers – they are affordable, service is impeccable and the quality of their product is second to none. Dealing with Vytas was an absolute pleasure. He allowed me to bespoke my order and kept me well informed at every stage of the process. When the windows and doors arrived, the quality of the finish was extremely impressive.
We are delighted with them and the standard of work and finish. Our builder is rapturous about them and was very pleased they came completely finished and ready to install with no painting or glazing required. Once again thank you.
Ranebrook fitted two slide and tilt wooden sashes for us in very tricky locations, one on the fourth floor into a difficult panelled dormer, the other above a conservatory. They were organised, clean, courteous and tidy. The windows were of excellent quality. Vytas was a pleasure to deal with and I would not only use them again but would definitely recommend them to others. I can’t really fault their service, prices or quality. And I wouldn’t say that very often…..
I used Ranebrook on a prestigious project in Hampstead, central london for the supply of 2 sliding sash windows. Products were great, price was right, and delivered on time as promised. I will use them again that is for sure.
Great quality windows and service. It’s so much warmer and quieter with all this wind we’ve been having. Highly recommended!
Ranebrook have been excellent throughout the process of purchasing a new window. Great service and delivery , would definitely use this company again.
The wooden windows which were supplied were very good. They were fitted well and on time. The people were courteous and helpful. I would be happy to use them again and to recommend them.
We have used Ranebrook Windows product & services since 2008, years are the best proof of what you can achieve. I would highly recommend Ranebrook team, specially Vytas, for their professional approach, being always on-time with the best product! Best wishes, Hedi Group
