ATTIC

THERMAL ENCLOSURE  A. Batt insulation is pre-installed in all areas where required or in areas that will be inaccessible for blown-in applications, and it is installed snug with no gaps.  B. Before attic insulation is blown-in, check that depth gauge strips are installed at a spacing of one per 300 square feet and that they will be visible from the attic access.  C. Rigid ventilation baffles are in place where specifed to ensure ventilation per building code (cardboard or plastic baffles are acceptable and must be installed correctly).  D. After insulation is blown-in, check for an even fll to the appropriate depth.  E. An attic tag is displayed at the top of the attic access, or near electrical panel, indicating the R-value, insulation depth and the correct number of insulation bags was brought for installation according to the coverage chart.  F. Mechanical platforms are pre-insulated to a minimum of R-30 (or per code, whichever is higher) when the HVAC is located in

unconditioned space. Height of platform should be such to not allow for batt insulation to be compressed.  G. End dam material is sufficiently rigid to prevent sagging. Batt insulation may be used only in locations where trusses are perpendicular to the exterior wall.  H. Before drywall is placed, check that the attic access is framed with wood material to allow full-depth insulation in the region of the access.  I. The attic access closure (hatch cover) is insulated to no less than 60% of the attic required insulation value, and the insulation is permanently mounted to the hatch cover with a gasket installed at the attic hatch. Or Attic access tents are acceptable.  J. During rough-in electrical, check that only IC (In Contact) and airtight can lights are used in any insulated ceilings.
