Different material options for French doors and windows.

The two most common materials are uPVC and timber for two different reasons. UPVC because it’s amongst and the cheapest material but still giving excellent results.

 Timber is a favourite for its visual effect. While not so cost-effective and more maintenance than uPVC, timber is often preferred indoors because of its visual finish effect, although it can be treated and used outside.

Other materials can include composite and aluminium. Composite is made from a mixture of timber, reinforced polymer glass and uPVC. It makes robust and long-lasting windows and doors.

Aluminium is another option and Windows & doors made from aluminium are long-lasting, strong and durable.
