Timber windows – frequently asked questions

Timber windows are available in standard sizes but can also be made to measure in any size, shape or design. Wood is an excellent natural insulator, making our windows super energy-efficient when paired with our Low-E coated double or triple glazing. Timber windows offer a traditional charm and elegance that plastic windows can’t match. Homebuyers agree – replacing traditional windows with plastic ones can lower property value, whereas wooden windows can add significant ‘kerb appeal’ to your home. Read more about the benefits of timber windows.

uPVC windows are the most popular window replacements in the UK today because of their low cost and easy maintenance. However, they’re not well suited to period and traditional homes or listed properties and those in conservation areas. Plastic frames are far less sustainable than wooden windows and typically only last half as long before requiring replacement. While more expensive than plastic windows, wooden windows offer higher lifetime value thanks to their good looks and long lifespan. Read our article on timber vs uPVC windows to learn more.

With proper maintenance, wooden windows can last 60 years or more, compared to around 35 years for uPVC and aluminium. Timber windows also give you the option of repainting the frames a fresh colour in the future, which is usually not possible with other materials.

Our timber windows are available single glazed, double glazed and – for maximum security and insulation – triple glazed. The best glazing for your new windows will depend on how well insulated your walls, doors and roof are and whether your local planning authority has special requirements for your property. Read more about your window glazing options, including the different glass patterns we offer.

Sliding sash windows slide open vertically and are ideal for period and traditional properties. Many pane configurations and features are available to evoke the perfect period for your home. Casement windows swing open like a door and are customisable for modern properties or traditional settings. These popular window types can be fully personalised to match your desired colour, size, shape and glass type. Need help deciding which windows are best for you? Check out our complete guide to choosing windows.

According to research by the WWF, ‘all the evidence suggests that, if you want to make the minimum impact on the environment while improving the performance of your home, you should choose wood windows’.

It takes around eight times more energy to create a uPVC window than a timber window. In contrast, sustainably-sourced wooden windows are naturally renewable, biodegradable, and can actually have a negative GWP (global warming potential).

Our timber windows are the sustainable choice because we have a renewable timber sourcing policy. We’re also extremely proud to have received FSC® (Forest Stewardship Council®) and PEFC™ multi-site chain of custody certifications. Both of these schemes are dedicated to promoting responsible forest management.

When properly looked after, timber windows won’t require recoating for at least ten years and, with just a few touch-ups, will last a lifetime (and up to twice as long as uPVC windows).

We recommend the following to maintain and extend the life of your timber windows:

Wash down a minimum of twice a year with a mild solution of soapy water and rinse off with clean water to remove any surface debris. This should be increased to a minimum four times a year in marine and industrial environments.
Once cleaned, scrape, lightly sand and touch up any areas of wear and tear with a matching microporous paint or stain. Any bare wood should be primed first.
All mechanical items, e.g. hinges, should be oiled with grease or neutral oil.
Weather seals should be checked and cleaned.
Vents should be cleaned and any blockages removed.
Timber is a natural product and therefore performs differently through the year. Seasonal adjustment may be required to ensure ongoing performance.

The cost of new timber windows depends on the size and shape you choose (bespoke designs cost more). The type of glazing also makes a difference. In general, timber windows have a higher initial cost than aluminium and uPVC windows. However, they have a higher lifetime return on investment because they last up to twice as long.

Timber windows add warmth, character, security and desirability to any home, which in turn adds value in the mind of prospective buyers. In contrast, fitting unsympathetic plastic windows in a period property could negatively impact its selling potential.

Yes! In fact, in many conservation areas, uPVC windows are strictly forbidden because they cannot come close to the elegant appearance of original wooden windows. All JELD-WEN windows are designed to meet building regulations in conservation areas. For more guidance, read our article on how to choose windows in conservation areas .
