This also explains the great strength of Masonite Structural Insulation. This insulation is made entirely of fibres obtained by exploding fresh, clean wood chips and it contains no artificial binder of any charac ter. There is nothing in Masonite to break down or disintegrate-^--it is permanent. Masonite is used as sheathing on the outside-: pf- studs for both heat and sound insulation under wood siding, brick, stone or tile veneer and stucco. It is also used on the inside of studs as a plaster base-- and-it bonds with the plaster so effectively that an average pull of more than 1000 lb. is required to pull the plaster from one square foot of Masonite Insulating Lath.

As the flakes leave the gun they are coated with spray of atomized adhesive agent (water glass) and projected to the surface to be insulated. The coated fibrous flakes form a blanket of insulation covering all cracks and.crevices. It can be applied to practically any surface in any desired thickness. Development--Sprayo-Flake was conceived by a layman while observing the installation of insulating material in his own home under course of construction. Prompted by a desire to overcome the inefficiency and attendant difficulties in volved in installing prepared types of insulating materials, the spray gun method was evolved. Further development proved the soundness of this theory. SprayoFlake method in one operation does a most thorough job, it eliminates entirely the labor of cutting, fitting, and nailing. Further development of the original idea dates back to the year of 1924 when specially designed equipment was per fected to apply Sprayo-Flake. The next step was adoption of an adhesive agent, addition of fire resisting qualities, and vermin proofing which was perfected in laboratories and practical usage in the building field. Distribution and Service--To assure the highest return per dollar invested in insulation the Sprayo-Flake Co. has adopted a modern economically sound plan of merchandising and distribution. Sprayo-Flake is supplied direct from factory to job through licensed operators. These licensed operators located in princi ple building centers are insulation special ists, financially responsible, and work on an exclusive franchise basis. Each instal lation is made by expertly trained me chanics under exacting supervision. This advanced plan of distribution enables the architect, builder, or owner to know the exact cost of insulation. SprayoFlake is always quoted on the basis of unit price per square foot or lump sum bid installed, including labor and material. Physical Characteristics The fibrous cellular structure and method of application gives Sprayo-Flake the desired characteristics of the ideal insulation material: 1. LOW THERMAL CONDUCTIVITY. 0.25 B.t.u. per hour per square foot per 1 in. thickness per degree temperature differential. 2. PRACTICABILITY. Can be applied to practically any surface in any . desired thickness. Seals cracks and crevices, calks around window and door frames. 3. FIRE RESISTANT. Pre-chemically treated fibrous material plus the sodium silicate binder produces a highly effective fire resisting insulation. 4. VERMIN PROOF. Alkali silicate binder and alkaline sulphate impregnation render Sprayo-Flake insulation repellant to vermin. 5. LIGHT WEIGHT. Flakey fibrous air cell structure weighs only 4.6 lb. per cubic foot installed. 6. PERMANENCY. The fabricated blanket of Sprayo-Flake in sulation is held in place securely by employ ing a sodium silicate cohesive binder. This binder also preserves the fibrous flakes from deterioration. The cohesive properties of sodium silicate have been utilized in the paper making industry for many years. . 7. LOW COST. . Sprayo-Flake insulation is manufactured and applied mechanically in one operation eliminat ing costly labor involved in cutting and fitting prepared types of materials. 8. FLEXIBILITY. Sprayo-Flake is sufficiently flexible to allow for usual expansion and contraction of structural members to which it is applied without im pairing its efficiency. 9. SOUND ABSORBENT. The cellular structure and resiliency of SprayoFlake render it a highly sound absorbent material. Note.--Conductivity and Transmission tests by such authorities as Prof. J. C.
