General refrigerated or cold storage facilities are essential for the safe handling and storage of food products and other goods. Without a storage area that provides a consistent environment that can sustain its integrity, many products would not be readily available to consumers.
EPS insulation board is perfect for use in walls and roofing systems in the construction of cold storage space that stores temperature-sensitive commodities, such as food and flowers. Temperatures in these spaces must be able to range from normal room temperature 68°F to cryogenic temperatures of -148°F.
The performance properties of EPS, including constant thermal resistance, dimensional stability, chemical inertness and sustainability, make it well suited for use as cold-storage insulation. Additionally, its closed-cell structure provides minimal water absorption and low-vapor permeance; which is an important design consideration for damp environments.
Application of EPS
Cold storage insulation is normally applied in two layers with joints staggered between those layers and boards tightly butted. EPS boards, therefore, must be firmly and permanently bonded to the wall, ceiling, and roof using adhesives.
The first layer of floor insulation is bonded to sub-slab while the second layer is installed dry. Thicker coatings of heavy-bodied adhesives may be used to provide some straightening or bridging on an irregular wall surface. Adhesives are applied to provide 100 percent contact and to fill any voids. Spot or strip applications of adhesives are used only where a vapor or air barrier is installed.
