Division 7 Ebook Page 120 EnergyComplete’ System: 2009 IECC Requirements for Air Sealing

What does the code say? How does it impact me? The 2009 IECC has several key sections addressing performance for air sealing of the building envelope: 402.4 Air Leakage ( Mandatory ) 402.4.1 Building Thermal Envelope 402.4.2 Air Sealing and Insulation 402.4.2.1 Testing Option 402.4.2.2 Visual Inspection Option TABLE 402.4.2 Air Barrier & Insulation Inspection Component Criteria Options for Verifying Air Sealing Performance The 2009 IECC offers a choice of two methods for verifying air sealing. Testing option. Building envelope tightness and insulation installation shall be considered acceptable when tested air leakage is less than 7 ACH when tested with a blower door at a pressure of 50 Pascals. Testing shall occur after rough in and after installation of penetrations of the building envelope, including penetrations for utilities, plumbing, electrical, ventilation, and combustion appliances. Visual inspection option. Building envelope tightness and insulation installation shall be considered acceptable when the items listed in Table 402.4.2, applicable to the method of construction, are field verified. Where required by the code official, an approved party independent from the installer of the insulation, shall inspect the air barrier and insulation. The EnergyComplete System from Owens Corning helps you meet stringent air sealing and insulation code requirements.
