What is a Sash Window?
Sash windows are common features of Georgian and Victorian buildings. Georgian sash windows are traditionally composed of two panels one of which would slide upwards via a weighted pulley mechanism to create an opening in one half of the window. Traditionally each panel was composed of six panes of glass.
Box sash windows are the same but the pulley mechanism is housed in a box to the side of the window rather than in the window frame itself.
Sash windows are very traditional and stylish and highly sought after. However, they can develop issues when the frames distort over time. Accoya is the perfect material for these beautiful windows as it will not shrink or swell keeping the window airtight and the mechanism smoothly functioning for decades.
case study
New double glazed timber sash windows
This property in Wiltshire was upgraded with new double glazed Accoya sashes installed into the existing window frames.
The homeowner wanted to upgrade their windows, which were cold and draughty. Accoya was chosen due to it being long lasting, with an anti-rot guarantee and requiring low maintenance. The new windows were manufactured and installed by approved manufacturers The Sash Window Workshop. Before installation, the windows were also factory coated using PPG coating in white to match the existing frames.
In total, 16 windows had new sashes installed into existing window frames with antique brass ironmongery.

Case Study
New wooden sash windows to improve family home
When Joe and Helen purchased their first family home in Southwest London they were sure of one thing, the whole property needed to undergo a major upgrade. Whilst they had big plans to extend the 3-story home and completely refurbish the property before they moved in, they also knew this was the only opportunity to replace the original rotting sash windows too.
After a huge amount of research online and visiting local joinery showrooms they opted for Accoya. It was recommended to them by friends and also the London joinery company they picked – London Box Sash. It was the most high-performance timber for the window frames and was sustainable too. The couple had faith in London Box Sash as they had been using Accoya for over 10 years and were well trained and knowledgeable about Accoya. The icing on the cake was that the Accoya window frames came with a 50-year warranty – not offered on any other wood. This gave confidence to the couple who decided Accoya windows were going to tick all the boxes.
“We couldn’t be more delighted with our new windows – they look fantastic! And most of all, there are no drafts to contend with anymore. Thank you to the team at London Box Sash for the great service you provided and of course for our Accoya windows!”
