Extend insulation in thickness indicated to envelop entire area to be insulated. Cut and fit <br /> tightly around obstructions and fill voids with insulation. Remove projections that interfere <br /> with placement. <br /> D. Water-Piping Coordination: If water piping is located within insulated exterior walls, <br /> coordinate location of piping to ensure that it is placed on warm side of insulation and insulation <br /> encapsulates piping. <br /> E. For preformed insulating units, provide sizes to fit applications indicated and selected from <br /> manufacturer's standard thicknesses, widths, and lengths. Apply single layer of insulation units <br /> to produce thickness indicated unless multiple layers are otherwise shown or required to make <br /> up total thickness. <br /> 3.4 INSTALLATION OF CAVITY-WALL INSULATION <br /> A. On units of foam-plastic board insulation, install pads of adhesive spaced approximately 24 <br /> inches (610 mm) o.c. both ways on inside face, and as recommended by manufacturer. <br /> Adhesive must be compatible with the spray fluid air barrier applied to wall sheathing. ( Fit <br /> courses of insulation between wall ties and other obstructions, with edges butted tightly in both <br /> directions. Press units firmly against inside substrates indicated. <br /> 1. Supplement adhesive attachment of insulation by securing boards with two-piece wall ties <br /> designed for this purpose and specified in Division 04 Section"Unit Masonry." <br /> B. Install units of cellular-glass insulation with closely fitting joints using method indicated: <br /> 1. Gob Method: Apply 4 gobs of adhesive per unit and set units firmly against inside wythe <br /> of masonry or other construction as shown. Apply gobs at each corner; spread gobs to <br /> form pads 4 inches (101 mm)in diameter by 1/4 inch(6 mm)thick. <br /> 2. Serrated-Trowel Method: Apply adhesive to entire surface of each cellular-glass <br /> insulation unit with serrated trowel complying with insulation manufacturer's written <br /> instructions. <br /> 3. Coat edges of insulation units with full bed of adhesive to seal joints between insulation <br /> and between insulation and adjoining construction. <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. Install insulation in cavities formed by framing members according to the following <br /> requirements: <br /> THERMAL INSULATION 072100 - 6 <br />
