It is an excellent non-conductor of heat, fight in weight and very slow burning. Cork as air insulating material in buildings is em-ployed in various forms:Granulated Cork This is made from cork cuttings and is used as afiller between double walls and studdings as well as be- 166 INSULATION tween floor and ceiling joists. It is considered as the bestfiller known for commercial uses because of its durabilityand small affinity for moisture. It is light in weight, will not pack or settle and ispractically odorless. Granulated cork is sold in a numberof grades of different degrees of fineness, and is commer-cially known as follows: unscreened cork, screened granu-lated cork and regranulated cork.

Screened Granulated Cork This is pure cork waste which is ground and screenedthrough various sized mesh screens. It is not as suitablefor use as a filler as the unscreened cork, on account of itseven size which allows of too many voids in the filling. Itwill weigh from six to twelve and one-half pounds percubic foot, according to its fineness. Regranulated Cork This is a by-product of the cork board factories and ismanufacture
