Designed specifically to be used on cold storage loading docks in conjunction with vertical dock levelers, the VC Series VertiCool insulated door utilizes 48” high and 4” thick closed-cell XEPS foam panels, an advanced dual-compression seal system, and heavy-duty polymer tracks to provide exceptional thermal protection at the loading dock. VertiCool doors also provide a far superior lifetime cost of ownership compared to conventional insulated sectional doors or vertical rise freezer doors. .
