Iconic PVCu Sliding Sash Windows

Sliding sash windows are amongst the most desirable window styles, not only due to their aesthetics, but also due to their historical association with style and wealth.
Our Iconic PVCu sliding sash windows are elegant, traditional and the perfect solution to preserve the heritage characteristics of your home. Choose one of our many convincing woodgrain finishes to mimic the look and feel of traditional timber windows.


PVCu allows us to fabricate an eminently durable and efficient sash window that looks nearly identical to the timber version. The PVCu profile we use is multichambered making it both strong and durable. With a sash window this close to the original and with virtually no maintenance required, there’s no reason not to choose PVCu for replacing your sash windows.


After performance, design is paramount. Our PVCu sash windows feature an easy clean slide and tilt facility. Besides that, we offer several features designed to replicate traditional timber sash windows, such as, bespoke shapes including gothic- and true arches, two types of sash horns, a stunning heritage hardware range, butt jointed deep bottom rail and seamless corner welds.

Glass Options

standard glass window

The standard glass unit used in our PVCu sliding sash window is 24mm in depth and is comprised of 4mm clear glass to the outside, a warm edge spacer bar and 4mm clear Low E glass on the inside. With this unit our sash windows achieve an energy rating of ‘B’.

The inclusion of argon gas in to the cavity of a double-glazed unit reduces the heat conductance between the panes. This happens because the gas is 6 times denser that air. With this glass unit, our sash windows achieve an energy rating of ‘A+’.

Pilkington Optiphon is an acoustic laminated glass that offers excellent noise reduction without compromising on light transmittance or impact performance. Two 3mm pieces of glass are put together with a noise reducing interlayer typically 0.8mm thick. This glass offers the dual benefit of noise reduction and security.

Warm edge spacer bars insulate the edges of a sealed glass unit and separate the panes of glass. Traditionally, spacer bars were made of aluminium, however the warm edge spacer bar used in our glass units is an extruded PVC material specifically designed to reduce transference of heat between the panes of glass keeping more heat inside the property. The spacer bar is available in 3 different colours; grey, black and white.
