Jackson BBH Mr. R. C. Maloof BBP Mr. S. E. Martin FS Mr. D. R. Suva BM Last year Flintkote received U. L. annrnval nn.-Itc natmlr Raal. cV>-ingle at 140% saturation using a 48 pound felt. The substrate contains a minimum of15% mineral wool fiber. Finished square'weight is, I believe, 220 pounds. Obviously, Flintkote is not advertising all this. Mineral wood is manufactured in several locations throughout the country and can usually be purchased at a delivered cost of $.12 to $.15 per pound, making it four times more expensive than wood flour. The payoff is not only in the finished product, but in the Felt Mill where the more open sheet dries at normal speed with low pressure steam, only. A negative aspect is a high percentage of shot (25% - 35%) which costs the same as the good material and rp(]lrps a considerahIp capital investment to remove, if ynn +n Glass fibers will perform the same function as the wool fibers but, of course, its use is cost prohibitive. There is no current technology to de-fiberize junk and core waste glass mat from roofing plants and/or glass mat plants, except by use of ~a~blast turnace, (This would make an exciting research project.) At Shreveport, 5 days of 48 pound felt production at 15%, would require about 103 tons of fiber. Five days will produce enough felt to meet 1983 sales plan on organic shingles for about 4 weeks. Just as soon as we get squared away on "woodless" felt, I'd like to run a trial and seek U. L. approval. Joe, will you please run the numbers out on this under the following assumptions (all production on DSPM-1): WIND SEALS 55 LB. "WOODLESS" HEAVYWEIGHT FELT VS 48 LB. MINERAL WOOL FELT 1.
