Fiberglass Reinforced Foam Core Sandwich Panel for Use as Refrigerated Semi-Trailer Side Walls and Roofs 820991
The sandwich composite is a lightweight structural panel. The top and bottom skins are a one-piece continuous high-strength polyester fiberglass reinforced sheet. The core is a low density polyurethane foam formulated to achieve the physical and thermal properties required for insulated semi-trailer applications. The panels are unique in that when they are employed as insulated semi-trailer walls and roofs, they result in a lighter stronger and more thermally efficient vehicle.
