FOAMULAR DURAPINK , Recover Roof Insulation QUALITY ASSURANCE A. Installer Qualifications: The installation work of this Section shall be performed by an experienced roofing contractor approved and certified by the roofing system manufacturer. B. Each insulation board must be labeled with manufacturer's name, product brand name, ASTM material specification reference, and identification of the third party inspection agency used for building code qualification. DELIVERY, STORAGE, AND HANDLING A. Deliver materials in manufacturer's original packaging. B. Store and protect products in accordance with manufacturer's instructions. Store in a dry area and protect from water, direct sunlight, flame, and ignition sources. Do not install insulation that has been damaged or wet . 1. In the event the board insulation becomes wet, wipe dry prior to installation. Note to Specifier: For proper fire protection of plastic foam in storage, consult the National Fire Protection Association (NFPA) standards or the authority having jurisdiction. PROJECT CONDITIONS A. Only single layer application permitted. All thicknesses of DURAPINK insulation are to be used in a single layer application only. DURAPINK insulation shall not be installed as a cover board over a layer, or layers, of FOAMULAR, THERMAPINK or other type of insulation being installed concurrently with the DURAPINK or left in place after tear off of an existing membrane. B. Limitations on recovered insulation: DURAPINK insulation, all thicknesses, shall not be installed over existing roofing systems that have more than 3" of insulation in place or a thermal resistance greater than R-17. C. Existing roof surface shall be free of ponded water, ice or snow. This precaution is to discourage potential future condensation on the underside of the retrofit membrane. D. Do not expose DURAPINK insulation to surfaces such as pipes, vent stacks or other rooftop appurtenances whose constant temperature is in excess of 165F. Exposure to the temperature under black single ply membranes is acceptable. Cyclical temperature at the insulation/membrane interface is anticipated to be approximately 195F under dark single ply membranes. DURAPINK insulation should not be exposed to 195F simultaneously on all surfaces. E. When insulation will be exposed to sunlight for prolonged periods due to job site delays, protect the insulation with a light colored opaque covering. Provisions should be made to prevent wind loss of insulation materials at the job site when partially open units of DURAPINK insulation are on hand. F. Roofs exposed to chemical discharge, or reflective vertical surfaces adjacent to the roof, require special consideration. Consult an Owens Corning representative for recommendations regarding system components. G. [Repair or replace deteriorated decking. Verify that existing roof drains are open and adequate to promote proper roof drainage.] ROOF BOARD INSULATION 07 22 16 - 2
