A lot of the industries that use curtain walls perform jobs that are either messy, loud, dangerous, or some combination of all three. Installing retractable curtain walls can add a level of safety that standard walls can’t offer. For example, the areas surrounding the curtain-enclosed can become contaminated with the materials used within—chemicals, oils, and other matter that may cause problems with not only cleanliness but also employees’ respiratory systems. Particles can get in the air and into people’s lungs, but even less serious complications with airborne particles, like contaminating other projects or getting equipment dirty, can be mitigated with retractable curtains. They also offer the potential for ventilation if necessary, since they can be immediately pulled back.
