• Position the batt and staple through the back surface of the extended flange to the side of the joist.
• Swing the batt into the cavity, fold the opposite flange over the other side of the next joist, and staple the flange to it spacing staples approximately every 8" (200mm) with beginning and ending staples about 1" (25mm) from the end of the flange. This installation allows full thickness recovery of R-19 insulation in 2x4 construction.
• For R-30 insulation in 2x6 construction, the insulation is compressed to approximately 81/2" (216mm), which results in an installed R-Value of 28 (RSI, 4.93).
• In each case, the insulation should hang approximately 3" (75mm) below the bottoms of the joists.

CertainTeed insulation products improve building energy efficiency and reduce building energy consumption for the life of the structure. As a result, they help conserve nonrenewable energy sources, decrease dependence on foreign oil and lower greenhouse gas emissions. In addition, the recycled content of CertainTeed fiber glass insulation meets the EPA minimum Recovered Material Guideline for fiber glass products consisting of preconsumer and post-consumer glass cullet.

CertainTeed Sustainable Insulation is GREENGUARD® Children & Schools Certified. Most CertainTeed fiber glass insulation products have been certified by the GREENGUARD Environmental Institute ,and meets the GREENGUARD's rigorous standards for low Volatile Organic Compound (VOC) emissions, including formaldehyde.
