Pipe Insulation Thickness Tables

Thickness 0 2 in 5 mm 0 4 in 10 mm material form 1 500 ft rolls.

Pipe insulation thickness tables.

A low thermal conductivity allows specified thermal performance standards to be achieved with thinner insulation. Eca y50 enhanced table 2. The following tables compare the minimum insulation thickness required to maintain the outside surface temperature at or below 140ºf. To meet the energy code requirement a minimum pipe insulation thickness of 4 5 in.

For product availability please contact your local owens corning area sales manager. The thickness of pipe insulation for most common residential cold water pipes is 1 2 thick. These tables were generated using the naima 3e plus computer program which follows the heat transfer calculation methodology in astm c680. Insulation thickness table to control heat loss.

The minimum pipe insulation thicknesses are given in two tables 6 8 3a and 6 8 3b in the standard. Hot cold water freeze protection. Based on nes y50 enhanced and enhanced capital allowance thickness tables. The table below indicates recommended insulation thickness.

In the new standard these tables are also reproduced in metric units. Tables 6 8 2a and 6 8 2b see figure 3 can be used to determine the insulation thickness for both supply and return air ductwork. Very hot systems like hot water and steam systems should also be insulated to avoid potential personal injuries. Our fiberglas pipe insulation portfolio is available in thicknesses up to 5 with inside diameters of up to 36.

There is usually no additional benefit of adding more than 1 2 thick fiberglass or rubber pipe insulation to cold water piping. To avoid heat loss and reduced system efficiency pipe work in heating systems should always be insulated. Indicative thickness mm of insulation for non domestic hot water 60 c and low temperature heating service areas 75 c to control heat loss. Iron pipe double layer nesting chart iron pipe size iron pipe outside diameter insulation wall thickness 1 1 2 2 3 3 4 4 5 6 0 840.

Refer to fiberglas pipe insulation sizing manual for more information. With a 25 year aged thermal conductivity as low as 0 025 w m k at 10 c mean kooltherm pipe insulation is one of the most thermally efficient insulation material commonly used. Hot water 60 c low temperature.
