PART 3 - EXECUTION

3.1   GENERAL

      A. Insulation is not to be installed until the piping systems have been checked and found free of
         all leaks. Surfaces shall be clean and dry before attempting to apply insulation. A
         professional insulator with adequate experience and ability shall install insulation.

      B. Provide hanger or pipe support shields of 16 gage (minimum) galvanized steel over or
         embedded in the insulation. Shield shall extend halfway up the pipe insulation cover and at
         least 6" on each side of the hanger. Securely fasten shield with pipe straps at each end.
         Insulate pipe anchors adequately to prevent moisture condensation problems.

ELEMENTARY SCHOOL G                                                          SECTION 22 07 00-3
                                                             INSULATION FOR PLUMBING SYSTEMS

      C. Insulation installed in exposed locations such as water heater rooms, equipment rooms, air
         handling unit rooms, all exterior above grade areas, kitchens, laundries, power houses, utility
         buildings, energy building or similarly identified locations where the insulation would be
         subject to physical damage shall be covered with metal jacketing. Elbows may be covered
         with fire rated and ozone resistant (for exterior locations) PVC covers in lieu of metal jacket.

3.2   WARM OR HOT SURFACES

      A. Insulate interior warm or hot surfaces with an operating temperature of over 120 degrees F
         and less than 400 degrees.

      B. These surfaces include hot water storage heater.

      C. Insulate with 1-1/2" thick calcium silicate blocks, securely wired on and covered with poultry
         wire. Apply a finish coat of 1/2' insulating finish cement over the poultry wire. Trowel the
         exterior smooth.

      D. Insulate hot surfaces operating at over 100 degrees F temperature with 3/4" V-rib spacing
         lath and 1-1/2" molded 85% magnesia or calcium silicate blocks wired on over the spacing
         lath. Apply poultry wire over the magnesia blocks and give a 1/2" coat of insulating finish
         cement. Trowel the exterior smooth.

3.3   COLD SURFACES

      A. Cold surfaces with operating temperatures below 70 degrees F to be insulated with 1"
         thickness foamed plastic or extruded polyethylene insulation. Surfaces include, but not
         limited to, domestic water chiller, domestic chilled water air separator, domestic chilled water
         expansion tank, and refrigerant suction line intercooler. The foamed plastic sheets shall be
         applied over a heavy coating of Johns-Manville #57 adhesive. The insulation shall be
         finished with a heavy coat of white aero-tube finish.

3.4   CONDENSATE PIPING FROM ICE MACHINES

      A. Insulate condensate piping and waste lines from ice machines with foamed plastic insulation
         or extruded polyethylene, one-half inch thickness.

      B. Mitre cut insulation to fit the pipe fittings. Use approved cement to seal all joints, seams, and
         ends in the insulation.

3.5   STORM WATER PIPING

      A. Shall be insulated with 1" thickness fiberglass pipe insulation. Prior to installing with
         insulation the pressure release paper shall be removed from the jacket laps. Pipe insulation
         shall be secured in place by applying pressure to the pressure sensitive closure system.
         Elbows shall be insulated with fiberglass inserted into 25/50 rated PVC (Aluminum) fitting
         covers.

      B. Insulation shall begin at the base of roof drain body and continue until piping penetrates
         grade level. (Complete for sound attenuation).

3.6   HORIZONTAL WASTE PIPING RECEIVING AIR-CONDITIONING CONDENSATE

      A. Shall be insulated with 1" thickness AP-T fiberglass pipe insulation. Prior to installing with
         insulation, the pressure release paper shall be removed from the jacket laps. The insulation
         shall be secured in place by applying pressure to the pressure sensitive closure system. All
                                          605 8497 000

          fittings shall be insulated with pipe insulation segments and finished with Foster's 30-35 vapor
          barrier coating or equal, reinforced with white open weave glass fabric.

3.7   HANDICAP LAVATORY EXPOSED WATER AND WASTE PIPING

      A. Shall be factory PRE-MOLDED insulation kits with foamed plastic insulation or extruded
         polyethylene, one-half inch thickness.
