Ultra-Insulating Low-Temperature Polyisocyanurate Foam Pipe Insulation
This very rigid insulation offers the lowest heat-flow rate of our pipe insulation and restricts absorption of water, air, and gas. It is typically used in process piping and chiller plants and performs best in applications below 50° F. To use outdoors, add metal jacketing.
Tubes have a kraft paper all-service jacket (ASJ) that resists mold and mildew by allowing moisture to evaporate. They have an adhesive strip closure.
