On vertical surfaces, set insulation units in adhesive applied according to manufacturer's written <br />instructions. Use adhesive recommended by insulation manufacturer. <br />If not otherwise indicated, extend insulation a minimum of 24 inches (610 mm) below <br />exterior grade line. <br />B. On horizontal surfaces, loosely lay insulation units according to manufacturer's written <br />instructions. Stagger end joints and tightly abut insulation units. <br />3.5 INSTALLATION OF GENERAL BUILDING INSULATION <br />A. Apply insulation units to substrates by method indicated, complying with manufacturer's written <br />instructions. If no specific method is indicated, bond units to substrate with adhesive or use <br />mechanical anchorage to provide permanent placement and support of units. <br />B. Seal joints between foam - plastic insulation units by applying adhesive, mastic, or sealant to <br />edges of each unit to form a tight seal as units are shoved into place. Fill voids in completed <br />installation with adhesive, mastic, or sealant as recommended by insulation manufacturer. <br />C. Set vapor- retarder -faced units with vapor retarder to warm side of construction, unless <br />otherwise indicated. <br />Tape joints and ruptures in vapor retarder, and seal each continuous area of insulation to <br />surrounding construction to ensure airtight installation. <br />D. Install mineral -fiber insulation in cavities formed by framing members according to the <br />following requirements: <br />1. Use insulation widths and lengths that fill the cavities formed by framing members. If <br />more than one length is required to fill cavity, provide lengths that will produce a snug fit <br />between ends. <br />2. Place insulation in cavities formed by framing members to produce a friction fit between <br />edges of insulation and adjoining framing members. <br />3. Maintain 3 -inch (76 -mm) clearance of insulation around recessed lighting fixtures. <br />4. For metal -framed wall cavities where cavity heights exceed 96 inches (2438 mm), <br />support unfaced blankets mechanically and support faced blankets by taping stapling <br />flanges to flanges of metal studs. <br />E. Install board insulation in curtain -wall construction where indicated on Drawings according to <br />curtain -wall manufacturer's written instructions. <br />1. Retain insulation in place by metal clips and straps or integral pockets within window <br />frames, spaced at intervals recommended in writing by insulation manufacturer to hold <br />insulation securely in place without touching spandrel glass. Maintain cavity width of <br />dimension indicated between insulation and glass. <br />2. Install insulation where it contacts perimeter fire- containment system to prevent <br />insulation from bowing under pressure from perimeter fire- containment system. <br />BUILDING INSULATION 07210-8 <br />
