uPVC Timber Alternative Windows

The organic appearance of timber windows, without the hefty price-tag.

Design without compromise

You’ll be glad to know that there are now worthy timber window alternatives available from Sheerwater Glass, manufactured from uPVC. Good quality, bespoke timber windows cost a lot more than people initially realise; sometimes costing triple the amount of our uPVC alternative.

Here at Sheerwater Glass, we strongly advise against installing low-cost timber as the potential for rot greatly increases, creating false economy.

We provide the highest quality uPVC Timber Alternative Windows without compromising on character, security or practicality.

  • Unique and intricate
  • Low maintenance with modern features
  • Impeccable quality

Discerning Property Owners

There are large quantities of uPVC windows on the market that claim to have the appearance of real wood. However, these false claims usually end up failing to satisfy the discerning customer in so many ways. If you are not constrained by planning restrictions and not forced into installing timber frames, we do have some excellent alternatives for you to consider from our Timber Alternative Range.

Most of our Timber Alternative Storm and Slimline Windows are purchased by property owners who desire real timber but have found the cost unpalatable and have concerns relating to maintenance. These customers have usually been recommended by a friend or architect to visit our well-stocked showroom for inspiration.
