Aluminum bi-fold doors are fairly cost effective and they look beautiful when contrasted with natural wooden features like with different types of windows or even any furniture you have in the surrounding area like above.

'Choosing the right framing material can be difficult given there are now so many options. With timber, steel, aluminum and uPVC all available some homeowners can find it overwhelming. We always recommend going for metal framed doors as timber frames expand and contract which can cause problems, and also require frequent special maintenance. For uPVC they have a shorted lifespan and with exposure to sunlight can become discolored. So really the choice comes down to aluminium or steel. Steel is more expensive but has an extremely long lifespan and real steel framing has an aesthetic that is hard to mimic. Aluminum is more cost-effective and requires little to no maintenance thanks to its natural rust and corrosion-resistant properties. If you’re choosing between steel and aluminum there is no better choice, it comes down to personal preference, budget and requirements of the project, such as thermal performance.' Adds Normoyle.

18. Elevate an open-plan design

Are bi-fold doors worth the money?

Modern and versatile, bi-fold patio doors are comprised of a series of panels that open, concertina-style, and stack at a right angle to the wall. The doors can be completely pushed back to provide unrestricted access to the garden patio space, particularly when paired with a level threshold. They offer a large glazed surface area when external and the cost usually starts around $600 for installation. With prices starting at around $100 for internal bi-folds, the benefits of both styles does outweigh the cost in our eyes.
