Selection of insulation materials must adjust measures to local conditions, should not only have good heat insulation performance, and economic and practical.
Insulation several types, one is processed into fixed shape and specifications of the plate, a fixed length, width and thickness, can choose according to the needs of library body installation of corresponding specification plate, high and medium temperature cold storage generally selected 10 centimeters thick plate, low temperature library and freeze library generally selected 12 cm or 15 cm thick plate;
Another can use spray polyurethane foam, the material directly spray to have been built of brick or concrete warehouse, after setting is moisture-proof and insulation.
Polyurethane and polystyrene insulation plate fat, etc. Better insulating polyurethane not bibulous, stays, but higher costs; Poor insulating polyphenyl ester water imbibition is strong, stays, but lower cost.
Made including the development of modern cold storage structure was fabricated, moistureproof layer and insulating layer of library components, field assembly, its advantage is construction convenient, fast, and mobile, but the cost is higher.
