uPVC Flush Sash Windows – the authentic alternative to timber

Allowing tradesmen to offer clients traditional timber visuals infused with the performance levels modern users expect, flush sash windows from the Timeless collection tout a uniquely ‘handcrafted’ feel, boasting a much more natural appearance thanks to all transoms and mullions coming butt jointed to echo traditional timber construction methods. Each window can be best summed up by the expression ‘History without the hassle’, incorporating A rated glass as standard within a style that’s undeniably classical.

As their name suggests, the design makes use of a sash that sits perfectly flush within the frame. Such a small feature goes a long way to cement the classic aesthetic being evoked, resulting in uPVC frames that look near identical to timber only with enhanced thermal and security features.

Each Timeless Flush Sash window is handcrafted by the Listers team in-house, using additional fixed sashes to produce clean sightlines. This means that Timeless windows are more aesthetically pleasing to the eye and have a more balanced look, effortlessly riding the line between classic design and modern performance/function.
