Fiberglas, Exterior Wall Thermal Insulation PART 3 - EXECUTION 3.1.1.1 EXAMINATION A. Examine the areas and conditions under which work of this section will be installed. Verify that adjacent materials are dry and ready to receive insulation. Verify mechanical and electrical services within walls have been tested and inspected. B. Provide written report listing conditions detrimental to performance of work in this section. Do not proceed with installation until unsatisfactory conditions have been corrected. 3.1.1.2 INSTALLATION, GENERAL A. Comply with manufacturer's installation instructions and ASTM C1320. Note to Specifier: Do not use unfaced insulation in exposed applications where there is potential for skin contact and irritation. Note to Specifier: Kraft and standard foil facings will burn and must not be left exposed. The facing must be installed in substantial contact with the unexposed surface of the ceiling, wall or floor finish. Protect facing from any open flame or heat source. B. Mechanical Fasteners: Curtainwall, 700 Series, Flame Spread 25 and Thermal Batts Insulation. Apply insulation directly to the interior surface of the exterior wall with appropriate spindle or prong type anchors. 1. Fasten anchors to wall by welding the pin to metal and then impale the insulation, or by using pre attached heads and welding them through the insulation. 2. Fasten anchors to wall with adhesive. Follow manufacturer's recommendations for surface preparation and adhesive pattern. 3. Impale insulation on anchor and secure with washer. Select pin lengths to ensure tight fit. Protect pin tips where subject to human contact. See manufacturer's diagram for impaling pin pattern. C. Adhesive Fastening: Curtainwall and 700 Series Insulation. Apply insulation with adhesives. Follow adhesive manufacturer's recommendations for surface preparation and adhesive pattern. D. Furring Strips: Thermal Batts, Flame Spread 25 and 700 Series Insulation 1. Install insulation between furring strips, hat channels, or Z shaped furring in areas where finish surface will be applied. 2. Contact the furring strip manufacturer for recommendations on the appropriate fastener system to use. E. Between Metal Studs: Thermal Batts and Flame Spread 25 Insulation. Friction fit insulation between studs after cover material has been installed on one side of the cavity. When unfaced insulation is used, and in applications without a cover material or where the stud depth is larger than the insulation thickness, use wire or metal straps to hold insulation in place. When faced insulation is used, the attachment flanges may be taped to the face of metal stud prior to applying the interior finish. 1. Provide supplementary support to hold the product in place until finish surface is applied when insulation is installed in heights over 8 feet. F. Between Wood Studs: Thermal Batts and Flame Spread 25 Insulation. Friction fit unfaced insulation between studs after cover material has been installed on one side of the cavity. When unfaced insulation is used, and in applications without a cover material, use wire or metal straps to hold insulation in place. When faced insulation is used staple attachment flanges to face or side of stud every 8 to 12 inches to prevent gaps along the edge of the vapor retarding facing.
