Fire-Safe Decking Option for Auckland International Airport

When designing the smoking area at the Auckland International Airport, Jasmax Architect, Michael Parkin prioritised materials that were easy to clean and maintain, provided a timber look finish, allowed easy access to all areas of the waterproof membrane below, and most importantly, were fire safe.

Being a public smoking area with heavy foot traffic, maintenance and durability were key factors in the decision-making process. A wood plastic material was already on the radar due to the low maintenance nature of the composition, so it came down to which offered the highest fire safety. It was decided that all composite decking products available in New Zealand would be fire tested which included setting each board alight. It was found that BiForm Solid Composite Decking burned the slowest of all options and was deemed the most suitable for the job.

Once BiForm was chosen, the last piece of the puzzle was to figure out how best to ensure that there would be easy access to the waterproof membrane below, all while working around a large seismic beam running through the middle of the area. BiForm’s design team designed a custom-made modular panel system that was developed with the specific purpose of being able to lift each individual panel, while also remaining easy to install and great to look at. BiForm was also used to form the large central seat element, complete with integrated stainless steel ashtrays and armrests.

The results speak for themselves. Through creative design and innovation, BiForm were able to supply and install a custom-made solution to a tricky situation. The Auckland International Airport now has a beautiful outdoor smokers’ deck that is custom built for purpose, low maintenance and fire safe. Michael Parkin has stated that BiForm met their expectations with a consistent and uniform look.
