DRYING KILN FOR LUMBER HAVING IMPROVED INSULATION

摘要

A kiln for the drying of lumber utilizing panels attached to the kiln structure. The attached panels form the interior surface and the exterior surface of the kiln. The panels have a cavity for the placement of insulating material. The insulating material is encapsulated in a liquid impervious container thus preventing condensates from infiltrating the insulating material. The isolation of the insulating material from the ambient moist air of the kiln maintains the insulating quality of the insulation normally lost due to exposure to moisture laden air and also aids in preventing the corrosive effect of moist insulation in contact with the metal surfaces.
