It is efficient at all temperatures between 1260 F and -- U0F. Gimco Rock Wool-- Gimco Flexfelt-- Gimco Rock Wool, the basic material from which all Gimco Insulating products are made and from which they derive their ex cellent insulating characteristics, is blown from a fused natural Rock Wool stone taken from our own quarries. Tests made by the United States Bureau of Standards show that Rock Wool has a thermal conductivity of 0.27 Btu per hour, per square foot, per degree fahrenheit at a density of 12 lb. per cubic foot-and a mean temperature of 90 F. This extremelylow conductivity is due to the large volume Gimco Flexfelt is a flexible insulation made by fabricating selected.Gimco Rock Wool between galvanized nettings or cop per. bearing metal lath in different com binations to meet various conditions. It is highly efficient up to 1250 F and will not burn or deteriorate with age. Flexfelt is obtainable in standard sizes 2 ft. by 4 ft. and 2 ft. by 8 ft., or in special sizes to fit any curved or irregular surface, of any \lesirable thickness, for all hot surfaces such as boilers, ovens, furnaces, hot water tanks, etc., with or without a plaster base. of minute air spaces entrapped by the rock wool fibers. Note the difference in volume in the following picture which shows a 20- pound rock and 20 pounds of Gimco Rock Wool. '- ' Being made from a silicate rock, Gimco Rock Wool is chemically stable and free from rot or disintegrating chemical action. Gimco positively will not burn--in fact, Gimco Flexfelt 738 m Hfrpjpe Insulation-- M||fc[>ipe Insulation is made by fabriyjjf^selected Gimco Rock Wool to meet ^^temperature up to 1250 F, for inside, underground conditions. Gimco [pipe Covering has all the excellent insujg&gand lasting qualities of Gimco Rock together with the following highly important feature, that is: its ability to rfiug" -the pipe and butt together at the joints, thus effectively stopping the flow |fair from under the Covering. The resiliijajce of Gimco Rock Wool is such that ..when two pieces are butted together, the ^fibers intermingle in such a manner as to practically eliminate the joint. |,The illustration shows Gimco Savall No. 220 Pipe Covering which is designed for neat inside work. Its construction incorporatesGimco Rock Wootand a.tough out side casing with canvas. It is economical in price and applies rapidly. The same type can be obtained with different outside cas ings of various compositions to meet par ticular conditions. tion shows this material applied to a 24-in. diameter pipe before the joints were sealed. Large pipes, such as shown, can be insu lated and waterproofed with great rapidity, and at a low cost by this method. Gimco No. SOS Gimco Quick-Fastening Method Styles 200, 201 and 203 are quickly ap plied by Gimco patented fastening meth ods, as shown above. Gimco House Insulation The lowconductivity, fireproof and verminproof features of Gimco Rock Wool Prod ucts make them an ideal home insulator. Gimco No. 110 Commercial Rock Wool is applied between the studding of the walls or laid over the ceiling either by hand or with blowing equipment in new or old' homes. A house insulated thrpughout with a Gimco Rock Wool filling can be heated with less fuel and boiler capacity. For new or old buildings. Gimco No. SSO Style No. 200 has an outside surface of metal lath for a plaster, base on large diameter pipes. Style No. 201 has a galvanized outside wire mesh. It is recommended for large diameter pipes which require a sheet metal . finish covering. Style No. 203-C. A, C. is selected Gimco RockWool fabricated between straight wire and copper screen wire which is covered with a waterproof membrane. The illustra Gimco No. 130B is No. 110 Commercial granulated into small nodules so that theWool may be poured between walls or into close places. It can be spread out over an . attic very rapidly.
