When installing a large freezer warehouse, it is important to have an insulated floor to ensure thermal efficiency and to protect against cold loss. Insulated floors help keep temperatures balanced, while also acting as an energy saver. A common approach is to use an insulated foam panel system on top of a slab foundation. This should be topped with a protective surface as well as additional coverings like a diamond plate overlay to complete the insulated floor for your drive-in cooler or drive in freezer warehouse.
Large freezer warehouses often will have an insulated concrete foundation that is built for the environment as well as heating systems in place that will prevent issues such as doors freezing shut. By installing heat cables alongside door frames, it increases the surface temperature and prevents ice forming between the frame and the door.
Frost heaving is a phenomenon that occurs when freezing temperatures cause moisture in the soil to thaw and expand. When moisture is created, and water freezes underground the ice has more volume and that expansion puts pressure on the slab. This can cause the foundation of the freezer warehouse floor to rise, resulting in a bumpy and uneven surface.
The phenomenon is especially common in areas with large seasonal temperature fluctuations. To reduce the risk of frost heaving, the floor should be insulated and sealed, and the surrounding soil should be packed and stabilized. This can help minimize the movement of water and prevent the ground from heaving. If the concrete is not insulated eventually cracks in the slab will decrease the insulation and increase energy consumption and create an overall dangerous environment.
