Insulation is used to retard heat gain and control condensation drip from cold-water plumbing, chilled-water, and refrigeration lines. It also efficiently reduces heat flow for hot-water plumbing, liquid-heating and dual-temperature piping.
The recommended temperature usage range for Pipe Insulation is -70�F to +220�F (-57�C to +105�C). For use on cold pipes, Pipe Insulation thicknesses have been calculated to control condensation on the insulation outer surface, as shown in the table of thickness recommendations.
The closed-cell structure of Insulation effectively retards the flow of moisture vapor, and is considered a low-transmittance vapor retarder. Insulation normally requires no supplemental vapor-retarder protection.
Additional vapor-retarder protection may be necessary for this insulation when installed on very-low-temperature piping or where exposed to continually high humidity conditions.
Please check your piping and insulation requirements on the chart of the air conditioners purchased. The I.D. dimensions should be identical to the suction line size. Insulation is required on any copper pipe that will be exposed after the expansion devices, therefore please measure the amount of exposed pipe and consider that every insulation piece has 6 feet in length.
