Bifold Doors
Open Up Your Living Space

As a general guide: a 2-panel set suits openings from about 1.2 to 1.8 metres; 3 panels covers 1.8 to 2.7 metres; 4 panels suits 2.7 to 3.6 metres; 5 panels covers 3.6 to 4.5 metres; and 6 or 7 panels can span openings up to 6 metres or more. Individual panel widths typically range from 600mm to 1000mm. Our surveyor will measure your exact opening and recommend the optimal number of panels to give you the best balance of proportions and maximum opening width. All measurements are taken at your free home survey.

Aluminium bifold doors need very little maintenance. Wipe the frames down with a damp cloth and mild soapy water a couple of times a year. The bottom track should be kept clear of leaves and grit, which can affect the rollers - a brush or vacuum works well. The hinges and locking points benefit from a small amount of silicone spray lubricant once a year to keep everything operating smoothly. Avoid oil-based lubricants as these can attract dirt. The glass can be cleaned using any standard glass cleaner.

Yes. Bifold doors can be configured to fold inward or outward. Outward-opening is more common as it maximises the usable floor space inside the room, but inward-opening is the better choice where there is no room on the outside for panels to swing out (for example, where the patio is tight or level with the sill). Inward-opening also means you can open the doors when it is raining without the panels getting wet before you can stand back. Our surveyor will discuss the best opening direction for your specific space.

We offer several threshold options to suit different requirements. A standard rebated threshold provides excellent weather sealing and is suitable for most installations. A low-profile 15mm threshold creates a near-level transition between inside and out, meeting Part M accessibility requirements, and is very popular for rear extensions where you want a seamless indoor-outdoor flow. A fully flush threshold is also available for the most level possible transition, though this requires careful detailing to manage drainage. We will discuss the best option for your floor levels and drainage during the survey.
