Pipe Insulation: Thickness & Material

Bare hot pipes and vessels bleed heat continuously, usually in plant rooms where nobody sees the cost, and pipe insulation (lagging) is one of the cheapest, fastest-payback measures in any facility. The heat is being lost every hour the system runs, the fix is well-understood, and the payback is often under a year. This lesson covers the scale of the loss, how thickness is chosen from standards, which material suits which service, and why cold pipes need a completely different approach.
