Even at high temperatures, these tubes remain flexible to stretch over components without tearing. They restrict absorption of water, air, and gas and are typically used on hot and cold water lines and electrical components.

Less flexible than rubber foam, this insulation restricts absorption of water, air, and gas. It is typically used in plumbing applications

The perforated vinyl facing allows moisture to evaporate and resists cracking and fading. These flexible sheets are good for insulating large enclosures.
