Asbestos Fibres, Inc., is a wholly owned subsidiary of Sprayed Insulation, Inc. which processes a proper type of fibre for Spraycraft. After years of development, Spraycraft is now ready for hard side wall application in any color. There is to be a national convention in Newark in the Fall, at which time an entire.new line of products all applied by the spraygun method will be introduced. Asbestos, June 1953, p. 26 Smith & Kanzler Corp., Linden, N.J. have added a "Spraybest" division for spray-gun applied asbestos fibre for fireproofing, insulation, condensation control and noise insulation. W.A. Burnham, associated with the development and improve ment of gun-applied fibers, has been appointed general manager. Asbestos, February 1954, p. 6 Keasbey & Mattison Co. -- History. In 1936, K & M introduced Sprayed "Limpet" Asbestos Acoustical material . . . The first asbestos acoustical product in this country. It differs widely from other noise killing materials in that it is sprayed from a gun like paint. Asbestos, December 1956, p. 18 A unique method of fireproofing structural steel members and steel floor units in building construction was recently tested and rated by the Underwriter's Laboratories, Inc. In addition to protection from fire, this method presents an entirely new concept for the protection of structural steel members against corrosion.

Pyrospray has excellent thermal insulating properties and high acoustical efficiency. Asbestos, November 1964, p. 4 Smith & Kanzler Co. announced the signing of a licensing agreement on "SprayCraft" asbestos mineral fibre with Nippon Asbestos. Nippon Asbestos will able to manufacture Spray Craft fireproofing and acoustical material as well as SprayCraft spraying machines for sale in Japan, Okinawa, Korea, Formosa, Hong Kong and the Philippines.

There are the building codes to be changed, the a r c hi tects to be shown, and the biuldeVs to be made ac-piainted with the advantages and limitations involved in installa tion. A_reccnt development along these lines is the appliea- tion of asbestos fibre by spr ay Oil to Cdrrugaled aslu-sios- cenient wall and roof "strTirl ni'cs.

This added to the. corrugated asbestos-cement board, weighing 4.2 pounds per square foot, makes a combined weight of 7.2 pounds per square foot. The K factor1, or conductivity of Fihresprav, being 0.31, and the 3.8" corru gated hoard 12.5, the combination was equivalent in insula tion value to a 13" masonry wall, complete with furring and plaster. In one building the Fibrespray insulation was painted, and in the other, it was left in its natural color. Being completely flexible in its application and treat ment. the thickness of Fibrespray can be custom tailored to the job to meet its particular need. Its monolithic construc tion allows no open joints for air circulation. Expansioi and contraction of the coated surface has no cracking, peel ing. or other destructive effect. . Fibrespray applied to ceilings or walls acts as a barrier i against flames in addition to possessing its insulation and I acoustical properties. This should prove to be a definite l safety measure and insurance economy. The application of Fibrespray is made^by men thoroly trained for this type of work, using machines developed for this particular purpose. Great care has been given to the selection of fibre grades and the binder which is incor porated at the factory. The processed fibre passes down the machine hopper thru a fan which " fluffs up" the fibre and sends it thru a hose. At the point of discharge i1 f is met by a liquid spray which combines with the openec I fibres in the air, so that they are datnpened just as the' I strike the surface to which they are applied. Thru a combination of spraying and tamping, the ma- 1 terial is built up in layers until the desired thickness has been reached when the surface is leveled and textured. The finished surface has a pleasing appearance which may be left in its natural light color, or painted if higher light re flection is desired. The added value of sound reduction by this treatment is attractive to those w ho realize that re- C o efficient ^pressed in B T l' p er hour p e r aqi ft. p e r d e g re e F. p e r 1" th ic k n e ss. ....

The acoustical value is natural- Vy lost where the material is covered up, but the harden JV-ff - .r.i .' ... in process of the fibre itself reduces but does not eliminate ^r''Ac'T.`A - | ;its acoustical value. This is accomplished by the addition of 1 special binder to improve body and surface strength.. ;. TY i 4' V'ftl: This method of insulation forms a felted blanket of A interlocking asbestos fibres which seals the entire surface teovered. If desired, structural members may be covered ' P^also. Particular attention must be given to method of ?J.. ,\ o, i sprayed insulation at the points of contact with structural and supporting members in order to secure maximum in- *sulating efficiency. ...4. -< At the present time conservative builders are-tiirning corrugatd asbestos-cement board only substitute, They feel that somehow its appearance is correct land that aS soon as other materials, at present in short; 'supply, become available, they will revert to these. It is en-; tirely likely, however, that these prejudices against a p -j^ pearanee will be strongly modified as time goes on. Actual / / 'experience with such construction, furnishing proof of it s ^ |durability and efficiency should sell builders on the id e a / ' of giving a combination of corrugated asbestos-cement and F Fibrespray insulation a lasting position in the field of per il manent buildings. ` i.\-' A Expense is a vital factor in all business construction,; ...y[ The building must not only do the job assigned to it; .it ' must earn money while doing so. A high, first cost is quite; handicap in the form of interest mil amortization charges. This is especially true if no more than fivedo tenj years of very profitable business are in sight.; Vote: " F ib r e s p ra y " a sb e s to s is m ade and I s k r u n u c a p f Acoustics, Inc.

Sprayed asbestos is well-suited for insulating all classes of industrial and domestic buildings. At the same time it solves the problem of increasing t her mal resistance of existing buildings, in addition, the treatment provides proof against vermin. By this method, which is called sprayed " L i m p e t ", specially treated asbestos fibres are projected simultan eously with a fine water spray from a multi-iet snrav gim Various grades of asbestos fibres are used m order to nu <t certain essential functions. The resul t ant mixture is pliable for two hours, dur ing which time the surface can I" flattened or shaped It becomes set in about eight hours. The advantages of spraxed asbestos are as follows 7 h ernial Lu^ii hit ion With a single shin roof, savings in fuel consumption of 50W ha\e been achicxed Buildings insulated in this way can be kept, it' required, at a l o v e r t e m p e ra t ur e a nd still provide the same degree of comfort. In summer, the t r e at m e n t will reduce the a m o u n t of solar heat coming through the roof and so makes inoie comfortable working conditions.
