Designed to limit heat loss on domestic hot-water lines and mitigate heat gain on cold systems, it helps protect lines from freezing.
Featuring an integrated, pressure-sensitive self-seal closure system, this dark grey polyolefin foam sleeve drastically minimizes installation labor time on the job site. Plumbing and HVAC specialists select this fiber-free, closed-cell insulation to protect lines against mold development and moisture absorption while actively dampening plumbing operational noises. Its low-VOC, formaldehyde-free chemical makeup ensures optimal indoor air quality standards are maintained within occupied structural spaces.
Before installing this 6-foot insulation section, cross-reference the 7/8-inch sizing to ensure it matches your 3/4-inch PEX, 7/8-inch copper tubing, or 1/2-inch iron pipe dimensions. The flexible, pre-scored design allows for clean manual cuts and straightforward routing around tight offsets or fittings. Choosing this reliable Armacell insulation guarantees a durable, fire-rated solution for maximizing residential energy savings and controlling condensation.
