Technical brilliance meets authentic design

Like so many of our customers, we cannot help but admire the simple elegance and classic detailing of traditional sash windows. Evocative and nostalgic, sash windows are the perfect way to let in the fresh air whilst perching on the sill, watching the world go by. 

As beautiful as they are, however, traditional timber sash windows can require a lot of maintenance and may not keep your home quite as snug as you’d like.

Rehau Heritage vertical sliding sash windows are, quite simply, the perfect replacement. Successfully approved and installed in conservation areas across the UK, the Rehau Heritage system incorporates the traditional features of timber sash windows, with the benefits and conveniences of uPVC.

Whether you are looking to add a touch of period style to your property, or you wish to faithfully replicate your existing sash windows, the Rehau Heritage window system is unmatched in authenticity, functionality, finish and style.

There are lots of details to consider when replacing your windows, whatever the age and heritage of your home. We’ll help you every step of the way, ensuring your new windows are faithful and complementary to the architectural style of your home.

Authentic, to the last detail

There’s more to traditional sash windows than the way they open and close. That’s why the Rehau Heritage system observes every last traditional detail, for true authenticity.

Additional features include a deep bottom rail, Georgian bars, run-through sash horns and foil laminate options, which replicate the look of painted wood.

There are, in fact, more than 20 laminate options, allowing you to create that beautiful woodgrain effect, whilst benefiting from the superior performance and security of uPVC.

Bedroom Windows

Convenience and safety

The Rehau Heritage system has been purpose-designed to accommodate any and all hardware requirements. It is even possible to clean the outside of the window from the inside, simply by tilting the window inwards via steel-reinforced sliding latches.

The latches are not only concealed for safety and aesthetic reasons, but are fully lockable to ensure the sash can’t be tilted by anyone but yourself.
