BATT INSULATION 23

Sound batts for vertical installation between studs shall be unfaced R-11 fiberglass batt insulation. At 6” stud 25 walls, use unfaced R-19 batts. Batt insulations thall be the manufacturer’s standard lengths and widths as 26 required to coordinate with spaces to be insulated and shall be one of the following types and manufactures (or 27 approved equal): 28 FS-25 Building Insulation Owens-Corning Fiberglass 29 FSK-25 Batt Insulation Manville Corporation 30 Batts shall be widths as required to tightly fit between studs, except that at all locations where gypsum drywall is 32 not shown on both sides of the partition, batts shall be supplied with foil on one face. 33 All batt insulation shall have maximum flame spread rating of 5 and smoke-developed rating of 15 per ASTM E 84. 35 Where batt insulation is included in rated wall, ceiling or floor construction, provide mineral wool batts which have 37 been tested and rated as required for the indicated assembly. 38

C. EXECUTION 40

PREPARATION 42

Clean substrate of substances harmful to insulations or vapor barriers, including removal of projections which 44 might puncture vapor barrier. 45

GENERAL 47

Comply with manufacturer’s written instructions for particular conditions of installation in each case. If printed 49 instructions are not available or do not apply to project conditions, consult manufacturer’s technical representative 50 for specific recommendations before proceeding with work. 51 Extend insulation full thickness as shown over entire area to be insulated. Cut and fit tightly around obstructions, 53 and fill and close voids with insulation. 54 Apply insulation units to substrate by method indicated, complying with manufacturer’s written recommendations. 56 If no specific method is indicated, bond units to substrate with adhesive or use mechanical anchorage to provide 57 permanent placement and support of units. 58

112-006 07200-2

Do not obstruct ventilation spaces except for firestopping. 1

INSTALLATION OF BATT INSULATION 3

Install batt insulation at the locations shown on the Drawings with vapor barriers on room side. Tightly fit into place 5 and push down in vertical spaces to assure avoidance of future settling. Securely staple in place as 6 recommended by the insulation manufacturer. Maintain all required minimum clearance between insulation and 7 fans, lights or other heat-producing equipment items. At locations where studs are less than full stud depth, strip 8 part of the insulation off of the non-vapor barrier side to reduce the total thickness to 1/2" greater than the available 9 space. 10

PROTECTION 12

Protect installed insulation and vapor barriers from possible physical abuses, where possible by non-delayed 14 installation of concealing work or, where that is not possible, by temporary covering or enclosure. Installer shall 15 advise Contractor of exposure hazards, including possible sources of deterioration and fire hazards. 16
