Complete Compiled Specification.pdf - Peck Ormsby Construction

Adhesives, mastics, and coatings shall be applied at the manufacturer's recommended minimum coverage per
gallon.
Where insulation pipes pass thru sound or fire-rated walls, floors, or ceilings, the insulation sleeves shall be
sound or fire-rated to match rating of surface penetrated.
All insulation which runs outside of the building, or inside of the building in areas where the insulation will be
exposed to physical abuse, shall be jacketed with a minimum thickness of .016 inch aluminum. The insulation
and aluminum shall be secured in place by a continuous friction type joint to provide a positive weatherproof seal
along the entire length of the aluminum jacket. Then, an aluminum preformed strap containing a permanently
plastic weatherproof sealant shall be centered over each circumferential joint, and secured by tightening on a
clip, or by use of separate 1/2 inch wide stainless steel banding. All elbows, tube, turns, sweeps, and bends shall
be insulated with mitered sections of aluminum-jacketed insulation. Joints shall be sealed with a sealing
compound and preformed aluminum bands. Valves shall be covered by prefabricated sections of
aluminum-jacketed insulation according to manufacturer's recommendation.
Insulation of storage tanks, manholes, hand holes, and at flanged ends of heat exchangers shall be applied so
that these items can be removed without damaging the insulation.
INSULATION WORKMANSHIP:
All insulation shall be applied by specialists experienced in the field, and shall be neat in appearance. Neatness
in appearance shall be equated to proper insulation application procedures, and sloppy workmanship will not be
tolerated. Work which is deemed unacceptable shall be condemned, removed, and replaced at the contractor's
expense.
Protect floors, valve handle, accessories, etc., to keep paste off areas not being insulated.
Splitting of longitudinal sections on flexible foam pipe insulation will not be permitted.
Do not install insulation on pipes which require heat taping without coordinating with mechanical contractor.
CLEAN-UP:
The piping shall be cleaned and tested prior to installation of insulation.
Fittings shall be cleaned after insulation is installed.
