American Panel custom manufactures walk-in cold rooms that fulfill many bulk storage needs. Panels are manufactured in 4-in. thickness and comply with all nationally accepted building codes. Foamed-in-place insulation offers the highest insulating value, reducing operating costs. Fiberglass reinforced polymer, used in door and frame, does not transmit heat and will not rust, warp, twist or support bacteria. Units are assembled and tested in American Panel’s factory prior to shipment to ensure correct installation the first time.
