INSULATING LUMBER INSULATING LUMBER < WHAT IT IS ELOTEX is the board- form insulation that com- bines high insulating value with structural strength. It is pro- duced from cane fibre. It is a strong, rigid, waterproofed board, having greater strength than wood sheathing on the wall, and the insulating value of cork. There is a use for Celotex in every building—as general heat and cold insulation, as sheath- ing, plaster base, roof insulation, interior finish, exterior finish and sound deadener. Insulation against heat and cold is always obtained at the cost of one mate- rial. In resisting the passage of heat and cold, the 4%-inch thick- ness of Celotex is equivalent to 1%-inches of lumber, or a 12-inch wall of concrete. To build with Celotex means to effect an annual saving of from 25 to 35 per cent in fuel consump- tion; an interior cool in summer and warm in winter. To build without insulation means to futilely attempt to heat all out- doors in winter and live in a hot- house in sumnier. uolje[Nsuy Jjooy pue suryyesys JoJ pas~) x9}0[90 yazyYIIy ‘HOOD “M UeULION TIT ‘9399TUTIM “Y}WIg URIINf Jo sUapIsay Residence of S.

Nichols Company. 2116 Jackson Street, Dallas, Texas. Gentlemen: In the construction of an apartment building for General Felix H. Robertson, recently completed at Waco, Texas, about 50,000 feet of ‘‘Celotex’’ was used, After investigating this material, we changed our specifica- tions, which originally called for metal lath, for we desired to give *“Celotex’’ a thorough test as a plaster base. The owner, as well as our- selves, is entirely satisfied with the results obtained, and we are pleased to report our findings in connection with ““Celotex’’ as follows: First: As a plaster base, it proved highly satisfactory, giving greater strength than could have been obtained through the use of metal or wood lath. Second: As a sound dead- ener and an insulator it is all that you claim it to be. Third: Its use saved the owners approximately $1100.00 in the cost of the building. This was not anticipated. We would have been satis- fied with the use of the material at an even greater cost because of its qual- ities as a sound deadener and an in- sulator. We are now specifying “Celotex’? and it is our intention to continue to do so, for we believe that we are serving the best interests of our clients thereby. Very truly yours, FRY/L3B YOUNG and YOUNG.

Lindner, Centlemen: It gives us great pleasure to write an unsolicited letter of commenda- tion on some of the superior features of your product, Celotex, over the heretofore more generally used lath and plaster. Most important of all, to us, is its deadening or sound-proof qualities. As you know, the walls of our general office ere lined with the Celotex, and the manner in which the noises from our pressroom are kept out of the office, with only a swing- ing door between, is almost unbelievable. Our private office is also absolutely sound-proof and conversation carried on there cannot be heard in the general OoLrfice: Tt is also truly remarkable as a temperature leveler and retainer. Our of- fices remain ideally cool in the summer, and in the colder weather are readily heated in a few moments and great comfort maintained with a very small amount of heat. It is often noticeable that our of- fices are still warm when we come to work in the morning after having been without heat since five o’clock of the previous evening - a matter of some fourteen hours. It is putting it mildly to say that we are perfectly satisfied with the results obtained from the use of Celotex and we wish you great success in the mar- keting of so meritorious an article.

Gentlemen: You are correct in your information in re. my having used "Celotex Insulating Lumber" in the recon- struction of a suburban cottage. The facts are, lirs. Marfield, in the late summer, purchased a little place at Ponchatoula, Louisiana, on which was located a very roughly constructed cabin of threo rooms. After a visit to your plant, I was immediately impressed with the value.of your product, and felt it could be used to good advantage in lining the cottage we had on our hands. After a great deal of persuasion, Urs. Marfield consented, and the transformation of the rough cottage into @® cozy three room bungalow was so complete within three or four days tims, that she was more than delighted with the Result, It gives me a great deal of pleasure to say that I consider Celotex not a coming, but an established product. pa DTT LS pd a RAN te ht iN LA Yours fery truly, LANG & WITCHELL ARCHITECTS April 12th, 1923.

Gentlemen: We have recently fitted up new ware rooms at No. 26 South Michigan Avenue, and have used in our Talking Machine demonstrating rooms, *““Celotex’”’ for partitions. It gives us pleasure to state that we have found this material to be highly satisfactory, not only in regard to its sound-proof qualities, put also from the standpoint of reson- ance. It has seemed to us and to our customers that the talking machines demonstrated in our rooms have an un- usually sonorous and resonant quality of tone; and we attribute this largely +o the fact that the walls of these rooms are lined with ‘‘Celotex’’. We are pleased to give this information to whosoever may wish to avail themselves of it, and to extend to anyone who may be interested in in- vestigating a cordial invitation to visit our ware rooms, and to see and hear for themselves how satisfactory this material has proved to be. Aside from the above the material itself is of a very pleasing texture; so much so that we decided to leave it in its natural state, rather than to stain or color it artificially.

These roofs are always practically flat and are ex- pected to retain heat in the tunnels as well as to exclude rain. We have experi- nented for a number of years and re-roofed our Dry House last year with a patented pnaterial guaranteed to retain heat and to be impervious to water. This roof was an obsolute failure within ninety days after its construction. Our last experiment consisted in treating our roof with a heavy coat of filler, then laying a covering of Celotex in hot asphalt, covering the Celotex with another coat of hot asphalt finished with three layer coat of asphalt paper. The results obtained have bcen somewhat star- tling as we have had to reduce our gas under dry house 60% to 70% allowing us to operate, since Celotex was applied, with 30% to 40% of our former gas consumption. We believe that we have solved the question of drier roof construction for brick plants--thanks to Celotex--and this is a question of grave importance to all prick manufacturers. I honestly believe that a roof, such as we have constructed, will pay for itself many times from saving in fuel alone and, at the same time, re- turn profits from the elimination of Dick spoiled on account of leaky roof. We are very glad to recommend Celotex as insulation for this class of construction.

Gentlemen: I have used Celotex for roof in- sulation under my roofing on many puildings in Chicago and its environs. - Celotex is the best roof insula- tion I have used for the following reasons: lst. It comes in sheets of large area and, therefore, can be handled by roofers according to their usual method. 2a. It is of more uniform thickness than any other roof insulation I have handled. ica It has a hard surface, so ; that the roofing pitch can pe applied to it and the roofing paper applied thereto without any unusual absorption of pitch, which is a great fault of other insulating materials. It has a high insulating value, because I have used it on some very par-— ticular jobs where the problem of ceiling condensation is very severe and it gave great satisfaction in these cases. Furthermore, it is a board of stiff texture, so after the roofing pitch and gravel are applied on the roof over the Celotex insulation a man can walk over the roof without danger of puncturing the paper, whereas if softer insulations are used this would occur. On the whole, I will say that Celotex is the most satisfactory roof in- sulation I have ever seen. Very respectfully yours, CHICAGO ROOFING & SUPPLY CO. RBM*JB Per (Weck? J I. O. O. F.

St. uouls, Mo. Gentlemen: - Replying to your letter of re- cent date requesting an expression from us as to the merits of Celotex for plaster and stucco base, we are pleased to say that it has given us very good results. We first tried it out ona bungalow for Mr. Ira Howe on Brownell Avenue, east of Collins Road, as a plaster base on outside walls. Not a single crack developed on either the brown or finish coats of plaster on these walls, whereas the interior walls which were regularly lathed had their usual quota of buckles and cracks. During the zero weather, the out- side walls of this house were just as warm as the interior. We also used it as a plaster base on a residence erected for Mr. J. P. Chambers on Highland Avenue, west of Collins Road. The results were the same. We have also used it as a stucco base at Nos. 600 and 602 Atlanta Avenue. Not a single crack has developed. MThe house at No. 600 has already received the dash coat but at No. 602 it can be seen to best advantage the good results obtained bating Portland cement stucco on a Celotex ase, As it is our policy to build quality into homes instead of ascertaining the cheapest method, we have not thus far compiled any figures showing comparative costs. We believe it to be an article of exceptional merit and intend to continue using it for this reason alone. Yours very truly, SUBURBAN CONSTRUCTION CO. 29 Homes on Wildwood Farms, Orion, Mich.
