FEATURES & BENEFITS

4

Attic is within the conditioned space

• Improved efficiency of HVAC system• HVAC equipment is in a temperate space• Opportunity for storage

No roof vents • More available space for solar panels• Better roof deck appearance• No wind-driven rain or embers into attic

Air sealing is done at the roof deck

• Simplifies air sealing at the top of the house by eliminating challenging attic floor penetrations like can lights, sprinkler heads, and duct work

All blown-in insulation • 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

Premium appearance • Provides a bright, finished appearance to the attic space • Conveys quality of construction to the home buyer, from the time of pre-drywall walk-

through to final occupancy
