'
TEN/TEST is a manufactured lumber made from spruce fibres, solidly pressed under hydraulic pressure into a strong, homogeneous board.' The fibres are chemi cally treated and water-proofed during process of manufacture, until the insula tion is non-hygroscopic, free from capillary attraction and moisture-resisting in service commensurate with the maximum degree of insulation obtainable.
Official Tests
Conductivity. TEN/TEST has a con ductivity of 0.33 B.T:U. per hour per square foot per degree fahr. per 1 in. thick. Authority: Professor E. A. Allcut, M. Sc. M. I. Mech. E. Mem. A.S.M.E. Professor of Applied Mechanics, University of Toronto. Tests performed by Hot-Plate method. Mean temperature 47.8 deg.
Tensile Strength 228 lb. per sq. in. Tests made on Jfe *n- board cut to strips 1 in. wide and tested in a Riehle Tensile Testing Machine, the grips being 2 in. apart. 228 lb. is the mean average of seven series of tests.
Transverse Strength (equal deflec tion) is 28.4 lb! Test made on Ko in. board, 6 in. wide, 18 in. long, on 12 in. centers, and load being applied to breaking point.
Plaster Bonding Strength 2163 lb. per sq. ft. Brown and scratch plaster coats were applied to standard K6 in board, and the pull registered in an Oslen Testing Machine. Authority: Columbia University Testing Laboratories, New York.
Moisture Resisting. TEN/TEST, after complete immersion in water for 24 hours, registered 37.5% increase in weight.

InsoBoard and InsoLath, structural insulating board made of wheat straw fiber, for home, factory, hotel, apart ment, office buildings, farm build ings, refrigerators and refrigerator cars, cold storage plants, etc. Inso Lath is ideal for plaster base.
Made from the long, tough, sterilized fibers of wheat straw, interlaced into flaw less, sturdy panels of an inch thick, 48 in. wide and 6 to 12 ft. long, InsoBoard is
Board is used, not only in new construc tion, but for the remodeling of old homes, to prevent heat losses through the roof. Time and the elements have no effect on it, submersion tests having shown the tendency to warp and buckle to be negligible.
InsoLath is made of the same material as InsoBoard. It is free-expanding and non-warping and takes the place of ordi nary wood lath as a plaster, base. It is fabricated into convenient sizes, 18 in. by 48 in. In InsoLath can be found (1) shiplapped, beveled edges and ends, which provide permanent expansion space all the way around, and so arranged that this space cannot be filled with plaster and (2) nailing slots which permit free expansion of lath without binding and resultant bulges and warping. The usual insulation fea tures are present in InsoLath as in Inso Board. It has great strength, increased plaster bond and is a perfected manypurpose material which successfully com bines all the desirable features of a perfect insulating plaster base.
used as sheathing or wall board. It adds structural strength as well as insulation and does not increase building costs, be cause it replaces boxing, lath or other materials. The labor cost of installing InsoBoard is less because it is easier and more quickly applied than other materials.
Its chief use is for the reduction of fuel bills in winter and for the minimizing of summer heat in the home. Fuel costs are reduced with InsoBoard insulation. Inso Board also is effective as sound-proofing material and it retards fire as well.
It insures warm floors and keeps a house free from dampness and draughts. Inso
The " flat-plate" test was used in tests of InsoBoard by G. F. Gebhardt, Mechani cal Engineer of the Armour Institute of Technology at Chicago an internationally known and recognized authority on insula tion values. The flat plate conductivity of InsoBoard is 0.33 Btu per. hour per square foot per degree Fahrenheit per one inch thickness, based on a density of 17 lb per cubic foot and a mean temperature of 68 F.
The result of these tests by this disin terested authority proves that InsoBoard possesses a high degree of insulating efficiency and should be specified on jobs calling for maximum structural insulation.
