PART 3 - EXECUTION NOTE TO SPECIFIER: Delete installation of materials not required from the following paragraphs. Delete paragraphs on installation of vapor retarders and air barriers if not the work of this Section. 3.1 EXAMINATION A. Examine substrates, flashing conditions, penetrations, adjoining construction and the conditions under which work is to be installed. Verify that surfaces are dry and free of oil, grease, dust, rust, or other contaminant. B. Report unacceptable conditions in writing. Do not proceed with the Work until unsatisfactory conditions have been corrected and surfaces are acceptable. D. Verify that fire stopping is in place before beginning to apply the air infiltration barrier with flexible seal technology. E. Verify the following conditions have been sealed with the air infiltration barrier before installing insulation and before closing in framing cavities: 1. Gaps between window units and framing. 2. Gaps between door heads, jambs, and sills and wall framing. 3. Interface of foundation or slab and sill plate. 4. Interface of band joists or rim joists and plates and subfloor. 5. Duct shafts, utility penetrations, knee walls and flue shafts opening to exterior or unconditioned space. F. Verify the following work is complete before installing insulation and before closing in framing cavities: 1. Vapor retarder or air barrier is installed at fireplace walls. 2. Air sealing is provided between the garage and conditioned spaces. 3. Vapor retarder or air barrier is installed in common walls between dwelling units. 4. Recessed light fixtures are air tight, IC rated, and sealed to gypsum board. a. Exception: Light fixtures in locations with conditioned spaces on both sides do not need to be air tight and do not need to be sealed unless required by another Section in the Project Manual. 3.2. PREPARATION A. Before beginning work, protect windows, plumbing fixtures, finish materials, and finish surfaces within work area by covering them with a plastic film. Secure edges of film to assure air infiltration barrier with flexible seal technology does not get behind the film. B. Sweep area to receive air infiltration barrier application to remove dust and other contaminants that will interfere with providing a thorough seal. C. Fill medium-sized gaps (gaps between 3/8 inch and 3 inches) between surfaces to be sealed with fiberglass insulation. Cover gaps greater than 3 inches with rigid, nonporous material such as gypsum board, extruded polystyrene insulation, sheathing, OSB, particle board, agrifiber particle board, or plywood secured to framing and apply sealant at the perimeter. D. To protect and prevent materials from sticking to eyes and skin when applying foam sealant materials wear, goggles or a face shield, a long sleeved shirt, chemical gloves and, if the installation site is dusty, a dust mask. E. If using products other than EnergyComplete Air Infiltration Barrier with Flexible Seal Technology that may contain isocyanates, comply fully with OSHA regulations regarding protective clothing, breathing apparatus, ventilation, and restricting access to areas of application.
