3 SEALED ATTICS HIGH PERFORMANCE CONDITIONED ATTIC SYSTEM 1 Air sealing 2 R-22 to R-49 netted & blown-in insulation (with or without a vapor retarder) 3

4 HIGH PERFORMANCE CONDITIONED ATTIC SYSTEM FEATURES & BENEFITS Attic is within the conditioned space No roof vents Air sealing is done at the roof deck All blown-in insulation Premium appearance Improved efficiency of HVAC system HVAC equipment is in a temperate space Opportunity for storage More available space for solar panels Better roof deck appearance No wind-driven rain or embers into attic Simplifies air sealing at the top of the house by eliminating challenging attic floor penetrations like can lights, sprinkler heads, and duct work Inspection-friendly: Blown-in system ensures successful QII rating Better performance: Without insulation voids and compression, there is no risk of thermal bridging, convective loops, or uninsulated areas Provides a bright, finished appearance to the attic space Conveys quality of construction to the home buyer, from the time of pre-drywall walkthrough to final occupancy 4
