4. IIPI Insulation The Technician must make sure that the insulation is installed using the insulation manufacturer’s procedures and instructions. Applicable recommendations should be followed when provided by:

5. IIPI Insulation The Insulation Contractors of Association of America, Spray Polyurethane Foam Alliance, Blown-in-Blankets Contractors Association, and/or Structural Insulated Panel Association.

6. IIPI Insulation The following standard installation procedures need to be followed for the specific applications listed: ASTM C1029 - 10 Standard Specification for Spray-Applied Rigid Cellular Polyurethane Thermal Insulation. ASTM C1320-10 Standard Practice for Installation of Mineral Fiber Batt and Blanket Thermal Insulation for Light Frame Construction.

7. IIPI Insulation Other items the Technician must consider when installing or repairing insulation include: Any existing interior or exterior moisture issues must be remediated prior to insulating the building shell. Whenever an enclosed cavity insulation upgrade covering 15% or more of the total building shell area is part of the home improvement’s upgrade plan, the Technician must perform a pre-and post-installation envelope leakage testing.

8. IIPI Insulation Vented eave or soffit baffles must be mechanically fastened to block wind entry into insulation, or to prevent insulation from blowing back into the attic. Baffles need to be installed to maintain clearance between the roof deck and baffle according to manufacturer specifications. Installation of the baffles will allow for the highest possible R-value above the top plate of the exterior wall.

9. IIPI Insulation When cellulose is used as fill over pitched ceilings: o Only stabilized products are allowed to be used. o Loose fill fiberglass will only be used on a slope less than or equal to a 6:12 pitch, or the slope application approved by the manufacturer, whichever is less. o Roof cavities will be insulated with loose fill according to manufacturer specifications without gaps, voids, compressions, misalignments or wind intrusions. o Insulation will be installed to contractual R-value.

10. IIPI Insulation Using fill tube, for dense pack over pitched ceilings, requires that 100% of each cavity will be completely filled to a consistent density that meets the following requirements: o Cellulose material will be installed to a minimum density of 3.5 pounds per cubic foot. o Loose fiberglass material will be installed and will be specifically approved for airflow resistance to a minimum density of 2.2 pounds per cubic foot.

11. IIPI Insulation Note: The number of bags installed will be confirmed and will match the number required based on the insulation manufacturer’s coverage chart. Additionally, for this type of application, insulation will be verified to prevent visible air movement using chemical smoke at 50 Pa of pressure difference.

12. IIPI Insulation Unvented flat roof cavities with existing insulation may be repaired using blown-in, loose fill insulation to fill all gaps, voids, compressions, misalignments or wind intrusions. The blown-in insulation will be installed to the prescribed R- value for the entire roof cavity where the repairs are being made.

13. Insulation Documentation Documentation of type of insulating material and it’s R-value (see Appendix 2) will be provided to the homeowners in accordance with 16 CFR 460-17 (CFR). The CFR is a law that states the installer must give the customer a contract or receipt that states the following for each area insulated and for each different type of insulation:

14. Insulation Documentation o Coverage Area. o Thickness. o R-Value. o Date. o Installers Signature.

15. Insulation Documentation For Loose fill Insulation, the additional requirements that must be included are: Installed thickness. Minimum settled thickness. Number of bags used (copy of receipt when available). For aluminum foil the additional requirements that must be included are: Number and thicknesses of air spaces. The direction of the heat flow.

16. IIPI HVAC 6.5
