Zoneworks’ TZD flexible fabric wall systems reduce facility energy costs and enhance employee comfort at the loading dock without the need to build permanent walls, or rigid panelized systems. These systems act as barriers to separate the inside dock from the rest of the facility, eliminating the need to heat or cool the expansive space accessed by trucks. The walls stop the rapid influx of cold or hot air, as well as humidity, every time an exterior dock door is opened. The modular wall system can also be used to completely enclose an open-air dock for better overall environmental control and energy savings. These custom-designed systems provide temperature separation up to 40°F (22°C). The modular wall panels are constructed of fire-retardant vinyl surrounding multiple layers of recyclable, anti-microbial polyester batting, and are securely interconnected with Velcro.
