Inner-Safe™ Non-Combustible Concealed Space Batt Insulation
Calculate the total number of packages of Inner-Safe needed by determining the area of the interstitial space (in square feet), by multiplying its length by its width. The number of square feet of Inner-Safe is marked on its packaging. Divide the total area of the interstitial space by the square footage in one package to determine the total number of packages required. Round up to the nearest whole package.
NFPA 13 Standard, Section 184.108.40.206.7.1 permits a maximum air gap of TWO INCHES at the top of the interstitial space.
