Giant Eagle Market #6550 The Bridges, Carmel, Indiana Building Shell Bid & Permit DLA Project 2014040.00 August 12, 2014 THERMAL INSULATION 072100 - 3 PART 3 - EXECUTION 3.1 INSTALLATION, GENERAL A. Comply with insulation manufacturer's written instructions applicable to products and applications indicated. B. Install insulation that is undamaged, dry, and unsoiled and that has not been left exposed to ice, rain, or snow at any time. C. Extend insulation to envelop entire area to be insulated. Cut and fit tightly around obstructions and fill voids with insulation. Remove projections that interfere with placement. D. Provide sizes to fit applications indicated and selected from manufacturer's standard thicknesses, widths, and lengths. Apply single layer of insulation units to produce thickness indicated unless multiple layers are otherwise shown or required to make up total thickness. 3.2 INSTALLATION OF BELOW-GRADE INSULATION A. On vertical surfaces, set insulation units according to manufacturer's written instructions. B. If not otherwise indicated, extend insulation a minimum of 36 inches below exterior grade line. C. On horizontal surfaces, loosely lay insulation units according to manufacturer's written instructions. Stagger end joints and tightly abut insulation units. D. If not otherwise indicated, extend insulation a minimum of 36 inches in from exterior walls. 3.3 INSTALLATION OF INSULATION FOR MASONRY SUBSTRATES A. Install board insulation on masonry substrates by adhesively attached, spindle-type insulation anchors as follows: 1. Fasten insulation anchors to concrete substrates with insulation anchor adhesive according to anchor manufacturer's written instructions. Space anchors according to insulation manufacturer's written instructions for insulation type, thickness, and application indicated. 2. Apply insulation standoffs to each spindle to create cavity width indicated between concrete substrate and insulation. 3. After adhesive has dried, install board insulation by pressing insulation into position over spindles and securing it tightly in place with insulation-retaining washers, taking care not to compress insulation below indicated thickness. 4. Where insulation will not be covered by other building materials, apply capped washers to tips of spindles.

Foam-Plastic Board Insulation: Install pads of adhesive spaced approximately 24 inches o.c. both ways on inside face, and as recommended by manufacturer. Fit courses of insulation between wall ties and other obstructions, with edges butted tightly in both directions. Press units firmly against inside substrates. 1. Supplement adhesive attachment of insulation by securing boards with two-piece wall ties designed for this purpose and specified in Section 042000 "Unit Masonry." 3.5 INSTALLATION OF INSULATION FOR FRAMED CONSTRUCTION A. Apply insulation units to substrates by method indicated, complying with manufacturer's written instructions. If no specific method is indicated, bond units to substrate with adhesive or use mechanical anchorage to provide permanent placement and support of units. B. Foam-Plastic Board Insulation: Seal joints between units by applying adhesive, mastic, or sealant to edges of each unit to form a tight seal as units are shoved into place. Fill voids in completed installation with adhesive, mastic, or sealant as recommended by insulation manufacturer. C. Glass-Fiber or Mineral-Wool Blanket Insulation: Install in cavities formed by framing members according to the following requirements: 1. Use insulation widths and lengths that fill the cavities formed by framing members. If more than one length is required to fill the cavities, provide lengths that will produce a snug fit between ends. 2. Place insulation in cavities formed by framing members to produce a friction fit between edges of insulation and adjoining framing members. 3. Maintain 3-inch clearance of insulation around recessed lighting fixtures not rated for or protected from contact with insulation. 4. For metal-framed wall cavities where cavity heights exceed 96 inches, support unfaced blankets mechanically. 3.6 INSTALLATION OF VAPOR RETARDERS A. Place vapor retarders on side of construction indicated on Drawings. Extend vapor retarders to extremities of areas to protect from vapor transmission. Secure vapor retarders in place with adhesives or other anchorage system as indicated. Extend vapor retarders to cover miscellaneous voids in insulated substrates, including those filled with loose-fiber insulation. B. Seal vertical joints in vapor retarders over framing by lapping no fewer than two studs. 1. Fasten vapor retarders to wood framing at top, end, and bottom edges; at perimeter of wall openings; and at lap joints. Space fasteners 16 inches o.c.

Before installing vapor retarders, apply urethane sealant to flanges of metal framing including runner tracks, metal studs, and framing around door and window openings. Seal overlapping joints in vapor retarders with vapor-retarder tape according to vapor- retarder manufacturer's written instructions. Seal butt joints with vapor-retarder tape. Locate all joints over framing members or other solid substrates. 3. Firmly attach vapor retarders to metal framing and solid substrates with vapor-retarder fasteners as recommended by vapor-retarder manufacturer. C. Seal joints caused by pipes, conduits, electrical boxes, and similar items penetrating vapor retarders with vapor-retarder tape to create an airtight seal between penetrating objects and vapor retarders. D. Repair tears or punctures in vapor retarders immediately before concealment by other work. Cover with vapor-retarder tape or another layer of vapor retarders. END OF SECTION 072100
