THE KENT 07 21 00- THE KENT Issue Date 05.09.18 THERMAL INSULATION THE KENT 3.3 INSTALLATION OF SLAB INSULATION A. On vertical slab edge and foundation surfaces, set insulation units using manufacturer's recommended adhesive according to manufacturer's written instructions. 1. If not otherwise indicated, extend insulation a minimum of 24 inches below exterior grade line. B. On horizontal surfaces, loosely lay insulation units according to manufacturer's written instructions. Stagger end joints and tightly abut insulation units. 1. If not otherwise indicated, extend insulation a minimum of 24 inches in from exterior walls. 3.4 INSTALLATION OF FOUNDATION WALL INSULATION A. Butt panels together for tight fit. B.

Fasten insulation anchors to concrete substrates with insulation anchor adhesive according to anchor manufacturer's written instructions. Space anchors according to insulation manufacturer's written instructions for insulation type, thickness, and application. 2. Apply insulation standoffs to each spindle to create cavity width indicated on Drawings between concrete substrate and insulation. 3. After adhesive has dried, install board insulation by pressing insulation into position over spindles and securing it tightly in place with insulation-retaining washers, taking care not to compress insulation. 4. Where insulation will not be covered by other building materials, apply capped washers to tips of spindles. C.

Attics: Install eave ventilation troughs between roof framing members in insulated attic spaces at vented eaves. 5. For wood-framed construction, install blankets according to ASTM C 1320 and as follows: a.

Vapor-Retarder-Faced Blankets: Tape joints and ruptures in vapor-retarder facings and seal each continuous area of insulation to ensure airtight installation. a. Exterior Walls: Set units with facing placed toward exterior of construction. B. Miscellaneous Voids: Install insulation in miscellaneous voids and cavity spaces where required to prevent gaps in insulation using the following materials: 1. Glass-Fiber Insulation: Compact to approximately 40 percent of normal maximum volume equaling a density of approximately 2.5 lb/cu. ft. C. Loose-Fill Insulation: Apply according to ASTM C 1015 and manufacturer's written instructions. Level horizontal applications to uniform thickness as indicated, lightly settle to uniform density, but do not compact excessively. 3.7 PROTECTION A. Protect installed insulation from damage due to harmful weather exposures, physical abuse, and other causes. Provide temporary coverings or enclosures where insulation is subject to abuse and cannot be concealed and protected by permanent construction immediately after installation. END OF SECTION 07 21 00
