There are several types of insulated materials that can be used to insulate cold systems. When combined with the appropriate vapor barriers, materials like fiberglass, mineral wool and cellular glass are rated for low temperatures. Because of their flexible and closed-cell nature, foam polyurethanes are also popular for insulating cold pipe systems. There are many types of flexible and rigid insulation techniques for cold pipe systems that involve a number of variations in materials used.
Ideal Cold Pipe Insulation Characteristics
1.Strong vapor barrier capability
2.Closed sell, non wicking components
3.Air tight application
Often, insulated materials that include all of these characteristics have one major drawback. Getting to the actual pipe surface for maintenance purposes often involves damaging or permanently removing the insulation that was applied. This can get rather expensive, especially if the area that needs to be reached is a valve that needs to be freely accessible. There are several removable insulation options for cold pipe systems that make reaching these areas easier and less costly.
