Vertical sliding secondary glazing has been specifically developed for traditional sash windows and period properties where maintaining the original appearance is essential. The vertically sliding panels mirror the operation of the original window, allowing smooth movement while significantly improving insulation, comfort and noise reduction.
Installed discreetly on the inside of your existing windows, vertical sliding secondary glazing creates an additional insulating barrier without affecting the external appearance of your property. This makes it one of the most popular solutions for listed buildings, conservation areas and heritage properties where replacement windows are often not permitted.
Our bespoke vertical sliding systems are manufactured to measure using slimline aluminium frames and high-performance glazing. Every installation is tailored to suit the exact dimensions of your existing windows, ensuring a precise fit and smooth operation.
One of the main advantages of vertical sliding secondary glazing is its ability to dramatically reduce external noise. Whether your property is located close to busy roads, railway lines or town centres, our systems help create a quieter, more peaceful indoor environment.
