  • Contractors – Consult Cottonwood Manufacturing for information on how to estimate the reduction in bags for framing and other factors in attics. Attic framing can vary from job to job so it is important to factor that in to each estimate for bags required. Charts shown do not have the framing factor reductions included. In general, framing will reduce the amount of bags required to be installed.
