          A.Verify that materials and accessories can be installed in accordance with Contract Documents and material manufacturers' recommendations.
 
          B.Verify, by inspecting product labeling, submittal data, and/or certifications which may accompany the shipments, that materials and accessories to be installed on the project comply with applicable specifications and standards and meet specified thermal and physical properties.
 
          C.Before starting work specified in this Section, carefully inspect the site and installed work of other trades and verify that such work is complete to the point where installation of materials and accessories specified in this Section can begin. If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.
          ** NOTE TO SPECIFIER ** Modify to suit Project scope and requirements.
 
          D.Items Not Insulated: Unless otherwise indicated, do not install insulation on the following:
          1.Drainage piping located in crawl spaces.
          2.Underground piping.
          3.Chrome-plated pipes and fittings unless there is a potential for personnel injury.
 
          3.2PREPARATION
 
          A.Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the Project conditions.
 
          B.Ensure that surfaces over which insulation is to be installed are clean and dry.
 
          C.Ensure that insulation is clean, dry, and in good mechanical condition with factory-applied vapor or weather barriers intact and undamaged. Wet, dirty, or damaged insulation shall not be acceptable for installation.
 
          D.Ensure that pressure testing of piping and fittings has been completed prior to installing insulation.
 
          3.3INSTALLATION
 
          A.Insulation contractor's employees shall be properly protected during installation of insulation. Protection shall include proper attire when handling and applying insulation materials, and shall include, but not be limited to, disposable dust respirators, gloves, hard hats, and eye protection.
 
          B.Install insulation materials and accessories in accordance with Contract Documents and manufacturer's published instructions to ensure that it will serve its intended purpose.
          1.Install insulation on piping subsequent to painting and acceptance tests.
          2.Install insulation materials with smooth and even surfaces. Insulate each continuous run of piping with full-length units of insulation, with single cut piece to complete run. Do not use cut pieces or scraps abutting each other. Butt insulation joints firmly to ensure complete, tight fit over piping surfaces.
          3.Maintain the integrity of factory-applied vapor retarder jacketing on pipe insulation, protecting it against puncture, tears or other damage. Seal circumferential joints with butt strips that are compatible with ASJ facing. Stapling is not required to complete the closure.
          4.On cold systems, seal penetrations of the ASJ and exposed ends of insulation with vapor barrier mastic. Coat staples used on cold pipe insulation with suitable sealant to maintain vapor barrier integrity. Mastic pipe section ends at every fourth pipe section joint and at each fitting to provide isolation of water incursion. If humidity in excess of 90% RH are expected, the ASJ shall be protected with either a mastic coating or a suitable vapor retarding outer jacket.
          5.When multiple layers are required, all inner layer(s) shall be No Wrap.
 
          C.Support piping so that the insulation is not compromised by the hanger or the effects of the hanger. Provide hanger spacing so that the circumferential joint may be made outside the hanger. Cover the evaporating holes with sealing tape for the length of the metal saddle.
          1.Piping systems 3 inches (76 mm) in diameter or less, insulated with fiberglass pipe insulation, may be supported by placing saddles of the proper length and spacing under the insulation.
          2.For hot or cold piping systems larger than 3 inches (76 mm) in diameter, operating at temperatures less than +200 degree F (93 degree C) and insulated with fiberglass, provide inserts such as foam or high-density fiberglass with sufficient compressive strength to support the weight of the piping system.
          3.At vertical runs, provide insulation support rings, as indicated on Drawings.
 
          D.Fittings:
          1.For systems operating below ambient temperature, wrap valves, fittings, and similar items in each piping system with wicking material to ensure a continuous path (100% coverage) for the removal of condensation, prior to installing insulation.
          2.Cover valves, fittings, and similar items in each piping system using one of the following methods:
          a.Mitered sections of insulation equivalent in thickness and composition to that installed on straight pipe runs.
          b.Insulation cement, equal in thickness to the adjoining insulation.
          c.PVC Fitting Covers insulated with material equal in thickness and composition to adjoining insulation.
          3.Seal fitting joints with vapor retarder sealing tapes or mastics.
          4.Use standard oversized practices for valves and flanges.
 
          E.Penetrations: Extend piping insulation without interruption through walls, floors and similar piping penetrations, except where otherwise indicated.
 
          F.Joints: Butt pipe insulation against hanger inserts. For hot pipes, stagger joints when operating temperature is over 400 degree F (204 degree C) double layer. Seal jacketing according to type being used. Seal self-sealing laps by firmly rubbing down surface of tape and flap.
          1.Taper and seal pipe insulation ends, regardless of service.
 
          G.Vertical Piping: Protect vertical piping to a height of 8 feet-0 inch (2.4 m) above the floor. Jacket insulated, exposed vertical piping within the building and insulated piping exposed to the outdoors with minimum 0.016 inch thick (0.4 mm) aluminum.
          ** NOTE TO SPECIFIER ** Delete if not required.
 
          H.Accessory Materials (Midwest): Install in conformance with the current edition of the Midwest Insulation Contractors Association (MICA) "Commercial & Industrial Insulation Standards."
 
          3.4FIELD QUALITY ASSURANCE
 
          A.Upon completion of insulation work, visually inspect the work and verify that it has been correctly installed. This may be done while work is in progress, to assure compliance with requirements herein to cover and protect insulation materials during installation.
 
          3.5PROTECTION
 
          A.Replace damaged insulation, which cannot be satisfactorily repaired, including insulation with vapor barrier damage and moisture-saturated insulation.
 
          B.The insulation installer shall advise the Contractor and the mechanical trades as to requirements for protection of the insulation work during the remainder of the construction period, to avoid damage and deterioration of the finished insulation work.
 
          C.Protect installed products until completion of project.
 
          D.Touch-up, repair or replace damaged products before Substantial Completion.
