Sliding Sash Windows Raynes Park, London

Sliding sash windows can maintain the traditional appearance of your London based home, without compromising on any of the modern benefits. Built to last, they effortlessly slide for a smooth and easy operation. Wimbledon’s uPVC sash windows are remarkably resistant to weather damage and warping.

Sliding sash windows feature near invisible joints in the frame, an elegant run through sash horn and a curvy ovolo frame shape. These are just a handful of the many innovative details that work together to create the most graceful and advanced sliding sash windows on the market.

Our uPVC sliding sash windows can replicate pre 1932 timber frames, giving a period look that is ideal for conservation or heritage areas. Sliding sash windows won’t stand out amongst traditional design features. Our sliding sash windows are one of the most popular uPVC windows across Wimbledon, South West London and Surrey. They are incredibly versatile and can be designed to suit any style of property from new projects to heritage homes. They can be tailored to suit precise sizes and in a variety of colour finishes to suit any home and the taste of any homeowner.

Our vertical sliding sash windows offer attractive designs that replicate the look of a classic sash window, with all the benefits of energy efficient double glazing. This elegant window is the perfect choice for homeowners looking to maintain the feel of the existing property or giving a traditional charm to a modern build.

Thermally Efficient

Unlike traditional wooden sliding sash windows, our profiles offer incredible thermal efficiency. Our sliding sash windows come with 24mm double glazed units as standard achieving an energy rating of ‘B’ as standard and a U value of 1.6W/m2K. With an argon gas filled unit the window can achieve an energy rating of ‘A’ and a U value as low as 1.4W/m2K.

Sliding sash windows come with ultra slim sightlines, meaning more glass and less frame. This will maximise the natural light, offering a bright and more comfortable space all year round.

With fuel prices constantly on the rise, we understand thermal performance is a priority to homeowners. The sliding sash window frames are built to last and to resist the ever changing conditions the London weather throws at them without losing their immaculate appearance. An innovative dedicated weather bar adds another level of defence against rainwater. This innovative feature is unique to this type of window.
