Timeless Heritage Flush Window Logo

The newly unveiled Heritage Flush Sash window is reminiscent of early 19th Century timber windows and is ideal for heritage homes, particularly in conservation areas where authentic looks are all-important

AUTHENTIC STYLE

Timeless is the most authentic, high-performing and stylish timber-alternative window and door range currently available in the UK.  Designed in Britain, with an understanding of the importance of the heritage requirements of traditional British homes, without compromising on modern security and thermal efficiency standards

As the name suggests, the Timeless Range will enhance any property, from the oldest character cottage to an architectural new build design.  Part of the appeal is the choice of styles, allowing you to select classic looks or contemporary styling to enhance the appearance of a country cottage, traditional townhouse, or provide an upmarket finish to a modern extension or new build property

ENERGY EFFICIENT

Innovative technology gives the Timeless Range the edge over most other uPVC windows.  The traditional flush sash styling, combined with an authentic timber effect finish and a stunning range of colours culminate in a range of windows fit to compliment any British home.  With thermal performance far exceeding that of timber windows, you will enjoy the look and feel of a classic traditional product whilst enjoying the benefits of modern insulating, structural, and security technology

PREMIUM FLUSH SASH TIMBER ALTERNATIVE

The Timeless Flush Sash system is crafted from modern, weatherproof PVC, which unlike traditional timber windows, will never need sanding or repainting and will never rot, split or swell. These low-maintenance windows will keep your home looking its best for years to come with no more work than an occasional wipe with a damp cloth

The Timeless Flush Sash is the latest innovation to come from one of the UK’s leading PVC systems suppliers.

Unlike chamfered and sculptured styles which are designed to add contour and detail to your windows, the Timeless Flush Sash sits flush within the frame and offers traditional, understated elegance.

Timeless Flush Sash can be specified in bespoke sizes to suit the windows of your home, whether it’s a tall townhouse or a quaint and cosy cottage.
