A roof sandwich insulated coldroom panel is a type of construction panel that is designed to provide insulation for cold rooms or refrigerated spaces. It typically consists of two metal sheets with a layer of insulation material (such as polyurethane foam) sandwiched in between them.

The panel is designed to provide thermal insulation to prevent the transfer of heat between the inside and outside of the cold room. The insulation material helps to maintain the desired temperature inside the room and reduces the energy required to cool the space.

Roof sandwich insulated coldroom panels are commonly used in the construction of commercial cold rooms, refrigerated warehouses, and other temperature-controlled environments. They are available in various sizes and thicknesses, depending on the specific application and level of insulation required.
