Our take on the SIOUX CHIEF 663-15812SS Foam Pipe Insulation

This is a 6 ft length of closed-cell polyethylene pipe insulation with a pressure-sensitive self-seal seam. It fits 1-5/8 in outside-diameter pipe (1-1/2 in CTS nominal) with a 1/2 in wall and an R-factor of 2.97. It is rated from -200 to 200 deg F and meets ASTM E84, so it suits both plumbing and HVAC lines. The peel-and-seal seam makes it faster to install than slip-on sleeves that need separate tape, and the closed-cell foam resists moisture uptake better than open-cell wraps.

Pros
  • Self-seal adhesive seam speeds installation
  • Closed-cell foam limits moisture absorption
  • Wide -200 to 200 deg F temperature range
  • R-factor 2.97 for a 1/2 in wall
  • Meets ASTM E84
Cons
  • Sold as a single 6 ft section, so long runs need several
  • Only fits 1-5/8 in OD pipe
  • Adhesive seam can lift if the pipe is dirty or wet
  • 1/2 in wall gives moderate R-value, not high-performance insulation

Questions and answers

What pipe size does it fit?
It has a 1-5/8 in inside diameter, sized for 1-1/2 in CTS pipe, which is about 1-5/8 in outside diameter. Measure your pipe's OD before buying.
How much R-value does it add?
R-factor 2.97 with the 1/2 in wall. That is typical for closed-cell polyethylene of this thickness and enough for condensation control and light heat-loss reduction.
Can it be used outdoors?
The closed-cell foam resists moisture, but the adhesive seam and foam are best protected from prolonged UV and weather. Wrap or jacket it for exposed outdoor runs.
What temperature range does it handle?
It is rated from -200 to 200 deg F, covering chilled water, domestic cold and hot water, and most HVAC lines within that range.
How long is each piece?
Each section is 6 ft long. Order enough sections to cover the full run plus a little overlap at joints.
