1. SCOPE

1.1 This standard prescribes the code of practice for the construction of cold storages with special reference to insulating and finishing the structures of permanent construction, such as brick, steel and concrete.

1.1.1 A variety of insulation materials are available. They may be classified as cellular plastics like polystyrene, polyurethane, polyisocyanurate foam, phenolic foam and fibrous materials, like bonded mineral wool, loose fill materials etc. The term insulation is, therefore, used in this standard to mean all these materials.

1.1.2 The requirements laid down in this code are based upon good engineering practice pertaining to adequacy and effective life of insulation including fire safety. Recommendations are further intended to provide reasonable safeguards against premature deterioration of the insulation and to ensure application practices consistent with safety.

1.1.3 The requirements specified in this code are intended to serve as minimum requirements, and are not to be construed as limiting good practice.

It must be stated that majority of users of cold storage use them to store vegetables, fruits, horticulture, dairy, poultry, marine or meat products which are sensitive to bacterial / fungal or other contaminants. In all such cases washable and hygienic envelopes are demanded. These types of cold storage constructions are briefly described in 1.1.4.

1.1.4 Cold storage insulation can also be performed by developments made in recent past using:

a) Pre-fabricated insulated panel fitted to outside of supporting structure. These panels may be of composite constructions providing weather barrier, exterior or interior or both sides facing and insulation all in one; and

b) Insulating panels consisting self-supporting structure to form the complete chambers by themselves; tongue and groove configuration of panels with additional camlock arrangement may be provided for jointing arrangement of one panel to the other panel; and panel joints should be completely sealed, for example, using silicone sealant by pressure gun.
