Do folding doors save space and add to the aesthetics? To all homeowners thinking of renovating old houses or buying new ones, you might be mulling over which type of door to choose for the interiors. The folding door is one type with multiple advantages and benefits that you may consider, and it comes in different shapes and sizes.
A folding door comprises several panels the user can fold or unfold to open or close the door. The door is also dubbed ‘bi-fold door’ or ‘Concertina door’ in relevance to the musical instrument. However, naming it a Bi-fold door is inaccurate as it usually encompasses 2, 4, or more panels. The panels move along a track with the aid of rollers, and the user can pull them back to one side using a knob.
From room separators to kitchen entrances, bi-fold doors are undoubtedly handy. They are suitable for separating any two spaces and can extend considerably, thus gaining an advantage over traditional doors concerning accessibility and visibility. This article will help you know more about folding doors and see if they suit your place. Now, let’s get started with the materials, shall we?
There are three kinds of folding doors:
Many people opt for aluminum for its strength and durability; this is why it is ideal for external bifold doors. Moreover, the power of aluminum results in a frame: glass ratio greater than any other material, increasing visibility. The robust material tolerates the sun well and protects the door from bending.
In addition to coming in various colors, aluminum bi-fold doors live long and look good simultaneously. Their main disadvantage is that they are expensive, but considering all their advantages, it is an investment.
This is a much cheaper option than aluminum but quickly loses its good looks. In addition to longevity and bending problems, the door might gain a yellow discoloration over the years. As said before, aluminum bi-fold entries can be considered an investment since UPVC would probably cost you more for maintenance.
Great natural looks are, of course, the main advantage of wooden folding doors. Moreover, manufacturers sometimes use engineered wood, which results from binding layers of wood with an adhesive, for producing this kind of door. Although engineered wood lives longer than natural wood, its internal moisture will eventually lead to bending. Regarding maintenance, engineered wood stands between aluminum and UPVC on that scale, meaning it needs less care than UPVC but still more than aluminum.
