The aïr 800 bifolding door offers several features that make it different from the other bifolding door brands on the market. In Part 1 of our 2 of our review we explained the importance of the supply chain and the warranty. Now, we take a look at the installation options and explain why they may matter to a homeowner.
aïr doors are slimmer than many other brands.

Air folding doors provide specifications other leading brands do not such as thin lines, improved engineering and weather performance.
When compared to the most popular brands of bifolding doors, aïr 800 bifolding doors offer narrow sight lines in critical areas of the doors. In fact, aïr doors are slimmer at the meeting stiles than all of the popular brands of bifolding doors including Smarts Visofold, AluK BSF70, SAPA Bifolding Doors, Origin and others.
How thin a bifolding door is may not be relevant to every customer, but for those desiring a slimline bifolding door, aïr doors are one to consider.
aīr bifolding doors are severe weather rated.
All quality bifolding door brands have been tested to meet the latest standards for air, wind and water penetration. The tests are measured in pascals, with most systems comfortably meeting 600 or 1200 pascals.
The aïr 800 bifolding door meets wind loads of up to 1800 pascals, that the manufacturer says equate to winds of more than 120mph.
aïr doors can be made taller than many other brands.
Most bifolding door systems are designed for maximum heights of 2500mm up to 2700mm. The achievable height of a bifolding door is also relevant to the width of the door as well.
Air doors are amongst only a handful of bifolding door brands designed to create doors of up to 3 metres in height. For the majority of home extensions and renovation projects, this height may not be significant. However, for those homeowners looking to create large glazed areas and tall folding doors, without the use of a glazed window above aïr doors can be considered alongside Schuco and others.
aïr doors have lower thresholds than many other bifolding doors.
When comparing the aïr folding door threshold to other systems, the standard, low and level threshold heights are lower than other bifolding door brands. The standard threshold offers a height of 40mm, the rebated threshold only 30mm and the low threshold just 19mm.
Furthermore, the low threshold option provides a light weather rating where other systems offer none.
air doors do not need a floating mullion.
For homeowners requiring a two or four panel bifolding door all sliding in one direction, aïr doors are possible without the requirement for a floating mullion. The floating mullion is commonly used to provide a locking point on an even number of doors but on the one side, creates a thicker and uneven sight line.
On some systems needing a floating mullion, the locking system frequently comprises a shoot bolt locking rather than a full multi-point lock.
Other considerations with bifolding door specifications.
Customer requirements around bifolding doors vary around aesthetics, performance, budget and hardware choices. Other clients drill down into specific elements of their bifolding door helping them make a decision on the most appropriate product for their home.
The aïr 800 bifolding door provides a higher specification product than other brands and finer details in its design. For example, the gaskets provided with aïr doors feature double interlocks as well as being Teflon coated. Door gaskets may not often be a key consideration, (outside of the anti-finger trap facility that this and other doors provide), however on an air door they’re designed to be more dirt resistant and provide enhanced weathering and protection.
The engineering behind the product also creates hidden benefits that the homeowner may not necessarily require, but are built into the product nonetheless. Aïr door leaves can accommodate greater glass weight at up to 120kg per leaf. Most other systems sit at the 80kg to 100kg weight limit.
Other enhancements built into the design include a marine grade paint finish, improved adjustment for the installer, a choice of luxury anti-bacterial handles and a stronger thermal break.
For the homeowner looking for a quality bifolding door with improved design and specifications, the aïr bifolding door can be considered alongside other top bifolding door names.
