London’s skyline might be dominated by glass skyscrapers, but its heart lies in period properties. And with period properties, comes beautiful architecture to preserve and protect. We’ve seen a surge in sales of timber flush sash windows in 2024, and orders into 2025, with feedback from customers and homeowners that the flush sash design of sustainable timber windows has a far broader appeal than perhaps even we predicted.
Timber flush sash windows are being requested for both new build and period properties, with sash windows-savvy London homeowners seeing them as the perfect blend of classic charm and modern performance. So, why are there so many more timber flush sash windows in London, and will we see the trend spread wider in 2025?
The timber flush sash window trend in London and beyond
Timber flush sash windows are a perfect match for London’s heritage properties, and at Nine Zero, we’ll ensure that historical beauty comes with the benefits of modern performance. With so many conservation areas and listed buildings in London, homeowners and developers often feel they are far more limited with materials and design than is the case. Sustainable timber windows tick all the right boxes for architects and specifiers, and the sleeker style of flush sash timber windows are emerging as the go-to for an increasing number of London homeowners. Our recent sales also tell us that trend is spreading.
Timber as a natural insulator
A key benefit timber casement windows have over uPVC or aluminium options is the fact they are natural insulators. When properly maintained, timber windows can provide excellent thermal insulation and help reduce heat transfer. This means it’s much easier to keep a property warm and energy efficient, driving down energy bills and reducing negative impact on the environment.
Flush sash timber windows: the sustainable choice
As the world shifts towards greener living, sustainable timber windows are becoming a top choice for eco-conscious homeowners. Timber sourced from responsibly managed forests has a much lower environmental impact than synthetic materials like uPVC. Unlike plastic, timber is both biodegradable and recyclable at the end of its lifecycle, helping to reduce waste. The manufacturing process for timber windows also typically leaves a smaller carbon footprint, making them an all-around smarter option for sustainability. By opting for timber flush sash windows, Londoners are combining timeless style with eco-friendly living – a combination that’s impossible to ignore.
