2.4 Accessories

1. Low expansion foam air sealant, caulking
2. Tape
3. Staples

Part 3 Execution

3.1 Examination

1. Coordination and meetings
2. Verify that site conditions are cleaned and that framing electrical and plumbing are completed and "signed Off" by appropriate code officials.

3.2 Wood Stud Installation

1. Studs installed to building code framing requirements (16" OC or 24" OC)
2. On Walls - Sheathing for exterior preferred as plywood or OSB
3. If FOAM: Require nailing to manufacturer's specifications
4. If FOAM (Poly-CSO) Require bracing to avoid racking
5. Siding should be attached only to studs
6. Install 3 PLY reinforced vapor/air barrier using "LIP STITCH" method per certified par/PAC™ applicator instructions

1. Install poly continuous with thermal insulation
2. Where wall poly meets ceiling poly, tape seam if required by local code.

3.4 Cellulose Fiber Installation

1. Install Cellulose to a minimum 3# PCF Non-Settling Density
2. Confirm density visually and physically by striking the wall with your hand to determine movement of blown-in cellulose insulation
3. Poly will be drum skin tight and pillowing from blower pneumatic pressure - will be minimized after air pressure is released
4. Insert hose into cavity and withdraw as density is achieved (min. 3lb. per cubic foot).

3.5 Sealing Penetration in Poly

1. Where required by code seal Poly to bottom plate and top plate with 3M tape.
2. Seal slits in poly used for access for blowing tube with 3M or Tyvek tape. Duct tape may be used if allowed by code.
3. Cut poly around electrical boxes and seal with approved tape.
4. Waste cellulose from clean up can be bagged and placed in the attic
