Timber window frames have enjoyed a long and enduring history in the UK. They enhance homes of varying styles the length and breadth of the country and have done so for centuries.

Thanks to its prolific use in construction, timber has for many years, been the default choice for door and window frames. It is still a popular option for traditional-style properties.

What types of wood are used

When choosing a timber bifold door, you’ll need to decide between softwood or hardwood, solid wood or engineered wood.

An engineered hardwood such as oak or meranti is more dimensionally stable than solid wood and less susceptible to environmental factors. However engineered softwoods such as spruce and pine are also suitable options and widely used in mainland Europe.

The Solarlux Woodline timber bifold door, for example, is available in meranti, spruce and pine as standard. It’s also available in other woods according to your choice.

Look for layers

Solid timber tends to move and flex over time, leading to warping, twisting or swelling. This may ultimately cause difficulty in opening and closing your folding door. To check whether a door is made from engineered or solid wood, look at its edge.

Engineered wood is made from three, sometimes four, layers of wood glued together under high pressure. These layers will be visible on the door edge. If there are no layers visible, it’s solid timber.

Sustainably sourced

Folding doors made from certified woods from sustainable forests are available from ODC, offering peace of mind for our customers as a result. All components are tested to be environmentally friendly and are mechanically connected which means they can be separated easily for recycling (when the time comes).

Thermal efficiency

Timber is a good insulator, preventing the transfer of cold temperatures from the outside. The thicker the frame, the higher the thermal value the finished door will offer.

Paints and varnishes

Your timber doors can be stained or painted according to your preference and all are supplied factory-finished. Our extensive range of lacquer stains is all ecologically-friendly and water-based. This popular option creates a warm and natural look, ideal for blending with wood floors, skirting and doors inside the home. Our most requested shade is a lovely, classic golden oak.

For painted folding doors, any RAL colour is possible to complement or contrast with brickwork, stone or render – we’ve even been asked to supply windows in bright green.

Aspect and maintenance

There’s no getting away from it, timber does require regular maintenance. However, it’s a factor that buyers are happy to accept to achieve the right look for their home. The level of maintenance will depend on the direction the folding door faces. Generally speaking, a south-facing stained door will have the highest maintenance needs, however, other environmental factors also come into play and we are happy to offer advice on your options.

We also offer many sliding and folding doors made from aluminium or a composite of timber and aluminium.
