Verify that surfaces and conditions are suitable prior to commencing work of this Section. Do not proceed with installation until unsatisfactory conditions have been corrected.
B.	Review requirements for sequencing of installation of all wall assembly components as demonstrated in the mock-up wall assembly.
3.2	INSTALLATION - BELOW-GRADE, SLAB-ON-GRADE INSULATION
A.	Place a 6-mil polyethylene vapor retarder sheet over graded, smooth dry, well tamped fill. Lap sheet a minimum of 2 inches (51 mm) and extend vertically up the perimeter foundation wall a minimum of 2 inches (51 mm).
B.	Lay insulation boards over the vapor retarder sheet, cutting to size as necessary. Adjacent insulation boards shall be installed with joints staggered. Subsequent layers of insulation board shall be installed over the lower layer with board joints staggered.
C.	Use sealant to seal gaps between the insulation board and the perimeter foundation wall. Apply sealant as recommended by the sealant manufacturer. 
D.	Place concrete over the insulation board and allow to cure before applying loads.
3.3	INSTALLATION - BELOW-GRADE, PERIMETER FOUNDATION INSULATION
A.	Install insulation board to the exterior side of masonry walls after the waterproofing membrane has cured according to the manufacturer's installation instructions. If the surface of the cured waterproofing membrane is not sufficiently tacky to hold the insulation board in place until backfilling takes place, then an adhesive shall be used to secure the insulation board to the wall. Apply adhesive to the insulation board as recommended by the adhesive manufacturer using the amount and pattern required for the application. 
B.	Place backfill directly in contact with the insulation board. Remove all large rocks and other debris that may damage insulation board during backfilling.
C.	Do not leave insulation boards exposed above grade. If insulation board is exposed above the grade line, then it shall be covered with an exterior cladding material or foundation covering.
3.4	INSTALLATION - CAVITY WALL INSULATION
A.	Install insulation board against the masonry wall using an adhesive or by friction fitting boards between masonry wall ties. When an adhesive is used, apply the adhesive using the amount and pattern recommended by the adhesive manufacturer. 
B.	Adjacent insulation board seams shall be staggered and all board edges shall be firmly butted together.
C.	Install the exterior veneer in accordance with the manufacturer's installation instructions.
3.5	INSTALLATION - FRAMED WALLS - EXTERIOR INSULATING SHEATHING AND ALTERNATE WRB / AIR BARRIER
A.	Begin by aligning the first board at a corner of the structure making sure that the bottom of the board overlaps the sill plate. When installing the insulation board as a WRB or air barrier, apply a bead of sealant along the face of the sill plate and press the insulation board into the sealant bead to form a seal.
B.	Insulation boards shall be installed with the board length in the vertical direction on the wall. Vertical joints shall be located over framing members.
C.	Attach the insulation board using fasteners that are appropriate for the framing type. Refer to the Kingspan Insulation LLC Insulation Installation Guide for requirements of the applicable fastener type and spacing requirements.
D.	Seal all gaps, penetrations and repair damaged areas by using a silicone sealant complying with ASTM C 920, Type S, Grade NS, Class 25, or expanding spray foam complying with AAMA 812, or either Kingspan GreenGuard Seam Tape or Kingspan GreenGuard Butyl Flashing.
E.	If the insulation board is intended to be used as an alternate WRB or air barrier, then tape seams using Kingspan GreenGuard Seam Tape and use Kingspan GreenGuard Butyl Flashing to seal around doors, windows and other wall penetrations. Use of other seam tape and self-adhering flashings shall approved by Kingspan Insulation LLC prior to installation.
F.	Install the exterior siding or cladding in accordance with the manufacturer's installation instructions. Refer to Table R703.4 of the International Residential Code (IRC) for attachment requirements for siding materials.
