No. 10105 Residence Conversions October 7, 2011 58 Kensington, 57 Dryads Green, 72 Dryads Green Smith College, Northampton, MA THERMAL INSULATION Page 4 of 5 072100 PART 3 -EXECUTION 3.1 EXAMINATION A.Examine substrates and conditions, with Installer present, for compliance with requirements of Sections in which substrates and related work are specified and for other conditions affecting performance. 1.Proceed with installation only after unsatisfactory conditions have been corrected. 3.2 PREPARATION A.Clean substrates of substances harmful to insulation or vapor retarders, including removing projections capable of puncturing vapor retarders or of interfering with insulation attachment. 3.3 INSTALLATION, GENERAL A.Comply with insulation manufacturer's written instructions applicable to products and application indicated. B.Install insulation that is undamaged, dry, and unsoiled and that has not been left exposed at any time to ice, rain, and snow. C.Extend insulation in thickness indicated to envelop entire area to be insulated. Cut and fit tightly around obstructions and fill voids with insulation. Remove projections that interfere with placement. 3.4 INSTALLATION OF CLOSED CELL FOAM INSULATION (Basement Walls) A.Apply insulation in continuous thickness from base of foundation wall to underside of wood sub-floor. B.Mask around existing windows and keep insulation clear of sash and frame. C.Maintain clearances around vents and thru-wall penetrations for mechanical equipment as recommended by equipment manufacturer. Proj. No. 10105 Residence Conversions October 7, 2011 58 Kensington, 57 Dryads Green, 72 Dryads Green Smith College, Northampton, MA THERMAL INSULATION Page 5 of 5 072100 3.5 INSTALLATION OF GENERAL BUILDING INSULATION 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.Place loose-fill insulation into spaces indicated, by machine blowing, to comply with ASTM C 1015. Level horizontal applications to uniform thickness as indicated, lightly settle to uniform density, but do not compact excessively. 1.For cellulosic-fiber loose-fill insulation, comply with the Cellulose Insulation Manufacturers Association's Special Report #3, "Standard Practice for Installing Cellulose Insulation." C.Apply self-supported, spray-applied cellulosic insulation according to manufacturer's written instructions. Do not apply insulation until installation of pipes, ducts, conduits, wiring, and electrical outlets in walls is completed and windows, electrical boxes, and other items not indicated to receive insulation are masked. After insulation is applied, make it flush with face of studs by using method recommended by insulation manufacturer. 3.6 INSTALLATION OF INSULATION IN CEILINGS FOR SOUND ATTENUATION A.Install loose filled cellulosic insulation in floor cavities above existing ceilings.
