Technical guide on insulating chilled water piping with mineral‑fiber pipe insulation (33°F‑60°F).
This guide, published by the North American Insulation Manufacturers Association (NAIMA), explains how to insulate chilled‑water piping systems using mineral‑fiber pipe insulation and vapor‑retarder jacketing. It covers performance criteria, installation methods, standards, and recommended insulation thickness for commercial and institutional buildings.
The document includes sections on pipe‑insulation materials (fiberglass, mineral wool), vapor‑retarder jacket systems, thermal‑conductivity testing, and detailed installation tips for fittings, hangers, and multi‑layer vapor dams.

The guide is intended for chilled‑water piping systems operating from 33 °F to 60 °F (0.5 °C to 15.6 °C).
The NAIMA 3E Plus® insulation‑thickness software program is used to calculate the minimum thickness based on design temperature and humidity criteria.
