Celluloseisolering anvendelsen stiger igen i USA. En del af grunden til denne vækst er at forskning foreslår at celluloseisolering måske yder en bygning bedre beskyttelse mod brandskade end glasuld, fordi cellulose er tættere end glasuld og derfor hæmmer ilttilførslen. ''National Research Council Canada'' forskning har støttet disse påstande.<ref>[http://nparc.cisti-icist.nrc-cnrc.gc.ca/npsi/ctrl?action=rtdoc&an=20331185 Fire Resistance Tests on Cellulose and Glass Fiber Insulated Wood Stud Shear Walls, Kodur, V.K.R.; Sultan, M.A.; Latour, J.C.; Leroux, P.; Monette, R.C., IRC-IR-806, ], [https://web.archive.org/web/20140216111534/http://nparc.cisti-icist.nrc-cnrc.gc.ca/npsi/ctrl?action=rtdoc&an=20331185 archive-backup] Citat: "...Results from fire tests F21, F21A, F22A and F32 can be used to indicate the effect of insulation types on the fire resistance of load-bearing wood stud shear walls (see Figure 16). The failure of the glass fibre insulated wall assembly (F21 and F21A) occurred at 42 and 43 minutes respectively, while the failure of the rock fibre and cellulose insulated wall assemblies occurred at 54 and 51 minutes respectively. As shown in Figure 18, these results suggest that the use of cellulose fibre insulation provides a higher fire resistance compared to glass fibre insulation, but a lower fire resistance compared to rock fibre insulation..."</ref>
