You need a way to protect your loading docks from the winter blasts, and keep warm or cool air from escaping. Cisco has some solutions for you.
Dock seals create a tighter seal between the dock and the truck to keeps winds from blowing in, and prevent dust, insects, exhaust fumes from entering your building. The truck backs up, and the trailer presses tightly against the seal.
Dock shelters can seal off your warehouse and interior loading dock from outside elements, keeping heating and cooling air inside while allowing full access to truck door height and width. The truck backs in, and the shelter surrounds the trailer forming a seal inside.
Weather seals can close gaps around doors, and seal uneven surfaces between leveler and sectional door. A weather wall can surround a door. You can also add a seal to the edges of your dock leveler to block drafts coming up from underneath.
