Timber Windows Buying Guide

Choosing your windows

To help you identify the range of windows that will best complement and enhance your living space, we have pulled together a useful checklist, highlighting the main areas you need to consider.  

The right material

Timber windows are a great choice, no matter what type of property you own. Thanks to advances in modern preservative treatments, they are now renowned for being beautiful and long lasting.

From a classic townhouse, to a character cottage or contemporary new build, we offer a variety of materials to meet your requirements.

  • Softwood: This is the most common wood type used in joinery and is available across our entire range. We are so confident in the quality of our softwood windows that they come with a 40 year guarantee to rot and fungal attack.
  • Oak: These popular wooden windows are bang on trend and can be coordinated with other joinery products, such as doors and stairs.

A question of style

The type of window you choose will often depend on the style of home you are building or the fittings you are replacing on a refurbishment.

Traditional properties are generally complemented by windows with bar details such as our victorian or cottage bar styles. We offer various designs for our casement and sliding sash ranges, including horizontal bars, cottage, Regency, Victorian and all bar.

Properties in a conservation area will probably need replacement windows similar in design to those being removed, to meet council planning requirements and ensure the locality retains its attractive appearance.

Energy performance

We offer double and triple glazing across our window ranges to suit your thermal performance requirements.

Our energy rated windows can be supplied with different levels of insulation to meet the varying U Values demanded of new build projects and refurbishments. The lower the U Value, the less heat is being lost, as it demonstrates the air flow is being controlled and prevented from escaping the house.

High performance windows are available in casement or sliding sash styles and can be fitted with tinted glazing to trap solar energy inside the home, which is an excellent way to generate extra warmth in winter. However, this may produce a 'greenhouse effect' in the summer months. 

The U Value you need to achieve on your project will be determined by Part L of the Building Regulations, which relates to the conservation of fuel and power. For more information, see our Building Regulations page. 

Operational considerations

It is important to consider how your windows will be used, as opening mechanisms can differ significantly.

Our Sliding Sash styles can be tilted, making cleaning easier. 

Hardware

Our windows are supplied with a suite of standard hardware to match the style and colour finish you have chosen. However, you can upgrade your window furniture to meet specific performance or aesthetic requirements.

  • Hinges: These vary depending on the window. Some ranges give you a chance to change the standard butt hinge to a projecting hinge, which are great for cleaning in those hard to reach areas, such as above conservatory roofs.
  • Ventilators: Standard ventilators are built into all of our ranges, apart from the high performance DreamVu™ windows and the inward opening Tilt and Turns, although they can be fitted if required. You can also specify different colours and extra vents as necessary.
  • Locking: We offer espagnolette multi point locking on all our windows as standard. This two or three point shootbolt system (depending on window height) is fitted to the opening section and locks into keeps within the frame for extra security.  

Choose glazing carefully

Glazing is normally decided by the aesthetic and thermal performance you require, but there are other factors to take into account.

If you live in an industrial area or near an airport, acoustic glass can be fitted to minimised noise. For added privacy, you could choose an attractively patterned obscure glass. 

Extra security

Protect your home with our Secured by Design windows, which are available in most of our ranges.

The scheme is owned and licensed by the Association of Chief Police Officers and provides enhance security features, giving you peace of mind and greater reassurance that your windows can withstand the most determined burglar.

Almost all JELD-WEN windows are available with a Secured by Design specification, which includes enhanced locking systems and optional laminated glass. 

The finishing touches

Choosing the right finish will not only protect your windows from the elements, but also keep maintenance to a minimum.

Your JELD-WEN windows can be supplied in microporous Hi Build paint finishes in white and pastel colours that are guaranteed for up to ten years, so you don't need to do anything but keep them clean!

Unfinished windows must be primed before they are exposed to the weather and finished within three months. All basecoat stained joinery needs a further coat no longer than a month after installation.

Think carefully before opting to paint your windows in black or other dark colours, as the sun can shorten the life of these finishes. Danish oil should not be used on JELD-WEN products.
