Gymnasiums large and small are very popular rooms for Screenflex Portable Partitions. Our clients like the non-scuffing hard rubber casters and they believe that since the gym has such a tall ceiling, that tall dividers are the best, the logic being that a tall divider will do more to absorb sound in such an environment. Does a portable wall which is taller than 6 feet tall absorb more sound than one which is 4 feet tall? Of course. However in a situation with a very tall ceiling such as a gymnasium with 20 ft. tall or higher ceilings, does cutting off a bit more of the gap between the top of the divider and the ceiling really help the sound situation that much? No. In the interest of making the best use of your dollars, if you have a room with a very tall ceiling where your new portable partitions will be used, we at Screenflex Portable Room Dividers recommend the portable walls of 6’0″ or 6’8″ height be used. True, taller dividers do give the feeling of being more in your own room. However, with very tall ceilings, we still recommend shorter dividers. This client uses 6’0″ tall dividers in their gym and it works great.
