The North American Insulation Manufacturers Association (NAIMA) has issued a new publication, “Guide to Insulating Chilled Water Piping Systems With Mineral Fiber Pipe Insulation.”
Developed for professional insulation contractors, the 36-page guide recommends methods for insulating chilled water piping systems using a vapor-sealed mineral fiber pipe insulation.
"Insulation systems are critical to limiting heat losses and preventing condensation on pipe surfaces operating from 33 degrees F to 60 degrees F (0.5 degrees C to 15.6 degrees C) within conditioned spaces in commercial and institutional buildings," says Charles Cottrell, vice president technical services for NAIMA. "When poorly applied, however, an insulation system can compromise insulation effectiveness.”
“NAIMA developed this step-by-step guide for applying vapor-sealed mineral fiber pipe insulation, which when installed according to the guide's recommendations, can effectively control condensation, help extend the life of the insulation system, and save energy," Cottrell says.
The guide addresses the installation of standard ASJ jacketed pipe insulation and presents recommendations based on reliable engineering principles and research, as well as consultation with manufacturers, contractors, and industry experts.
It details insulation application on straight pipe; on pipe system fittings including flanges, couplings, elbows, tees, and valves; and on 45- and 90-degree elbows. Also included are details on vapor dams, pipe supports, and field-applied jackets.
Other sections include performance criteria, a guide specification, and installation checklist. Click here to download a free copy of the guide.

The perception that the U.S. has not been able to curb development in flood-prone areas is mostly inaccurate, according to new research from climate adaptation experts. A national survey of floodplain development between 2001 and 2019 found that fewer structures were built in floodplains than might be expected if cities were building at random.
