Insulation Insul-Wool Insulation Corp. General Offices, Wichita, Kansas Branches in Principal Cities Manufacturers and Distributors of Insul-Wool Insul-Wool is a fibre insulation of the "fill" type--made of wood pulp, a natural insulating material. By the exclusive " InsulWool" method the wood pulp is converted into a loose fluffy substance which, when installed in a building, forms a soft heat-resisting blanket having millions of tiny air cells cap able of resisting passage of either heat or cold. UNIFORMITY OF PRODUCT Only one grade of Insul-Wool is made and every "run" is tested at the factory to insure uniformity of product and unvarying high quality. It is free from grit, silicon particles, or "shot." FIRE PROOF AND VERMIN PROOF A special "Insul-Wool" method of chemical treatment makes Insul-Wool thoroughly ver min proof and fire proof. It has been approved by the National Board of Fire Underwriters. "INSUL-WOOL" SERVICE Insul-Wool is distributed and installed only by specially trained men--direct factory re presentatives or men in the organizations of the largest insulation material dealers through out the United States.

TEN/TEST is a manufactured lumber made from spruce fibres, solidly pressed under hydraulic pressure into a strong, homogeneous board. The fibres are chemically treated and water-proofed during process of manufacture, until the insulation is non-hygroscopic, free from capillary attraction and moisture-resisting in service commensurate with the maximum degree of insulation obtainable.
