IMPROVED GLASS-FIBER HEAT-INSULATING STRUCTURE

摘要

PURPOSE: To prevent lowering of a recovery rate at the time of opening a glass fiber heat insulating structure or at the time of removing compressive force by removing moisture from a glass fiber body by putting a drying agent in an outside plastic layer in the vicinity of the glass fiber body. CONSTITUTION: A plastic made outside layer 14 is a high density polyethylene layer and constitutes a moistureproofing part against a glass fiber body 12. A drying agent is put in the plastic made outside layer 14 in the vicinity of the glass fiber body 12. This drying agent consists of a plural number of small bags 18. The small bag 18 is made of moisture permeable paper, and a plural number of the drying agents are stored in it. Relative moisture of the glass fiber body 12 is lowered by putting a sufficient number of the drying agents small bags 18 in it. Consequently, recovered thickness of a heat insulated structure at the time of opening the compressed glass fiber heat insulated structure body is improved after storing it for a long period of time.
