Tha firaEafcog waa dona oa a Wondar Building for tha Qovarnaeat la tha Plttaburgh axW*^.t waa dona In July* 1958. Tha building la air- ooadltlonad aad haatad. Tha building haa baan inapaetad at wary frequent Intervals and aooording to Kal haa baan aatiraly aatlafaotory with a 1* thlckaasa appllad directly to tha natal. " Aa laarioaa Lagloa Building in tha Pittsburgh afaa end also a Wondar Building wAA appllad la tha viatartiaa aad tha firat half of tha Joba daflnitaly frosa ahortly after application. Tha balanoa of tha work vaa dona with aoaa heat available. Thera haa baea ao difficulty with adheaioa on theao Jobe. Thera haw* baan about 1$ Jobe dona la the Plttaburgh area to data. ill of tha Joba dona to far haw* baan dona by Warner Insulation Company, who war* originally applioatora for oaa of tha aabaatoa type notarial* They haw* applied owar 8,000 baga of notarial to data, ill of It haa baan appllad 1" thick la one applioatloa. They awaa haw* applied aoaa to owerhaad doora oa building* at tha airport at Plttaburgh. So far, tha Spra-Znaulatloa haa baan produoad aooording to tha formula given to ua for Mono-Kota. Zoaolit* has boon glwlng apaoial attention to nixing proeaduraa, aapaolally tha natter of fluffing aabaatoa, la order to obtain tha lightest possible notarial at the plant. They elala that 14 to 15 lbs. is about the bast density thay'w* had at Chicagoi California Zonollt* has report edly produce# aoaa notarial at iz lba. per ou.ft. Tha bast I factor they haw* obtained ao far la .63. Mel Is la hopaa that event ally they will gat material with a factor as low aa *50. Ha points out that their particular problem haa been the air structure in this mix, it is a little weak and the density la quite Increased as tha notarial la put through a pump. Ea la still working oa air entraining that will haw* batter strength. */ Z explained that natter of material sagging on atael beans after we bad appllad a quarter of an inch or so. Mel said that sons sagging has been experienced and thet tha beat way to prevent it la to work with a drier mix and have the aaterial thoroughly nixed. H* also pointed out the setting of the pin in tha noasl* la extremely important, that there should b* a definite spray rather than having the aaterial cone out in a stream.
