Does Acousta-Wal cause a maintenance problem?
This is one of the most commonly asked questions. Walls constructed with Acousta-Wal blocks actually require much less maintenance than walls faced with other acoustical materials. This is particularly true when Astra-Glaze-SW®+/Acousta-Wal glazed acoustical units are used. When dust or dirt settles in the slots, it can be removed easily with a vacuum cleaner. Neither the fibrous filler nor the individual fibers will be disturbed.
