About Selecting Thermal Insulation

Fiberglass Pipe Insulation

This common insulation material is typically used on hot and cold water lines and in process piping.

Flexible Rubber Foam Pipe Insulation

Soft and easy to install, this insulation restricts absorption of water, air, and gas. It is often used on cold and hot water lines and refrigeration lines.

Economical Flexible Polyethylene Foam Pipe Insulation

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

Quick-Install Fiberglass Pipe Insulation

Hook-and-loop fasteners make it easy to install, remove, and reuse this flexible insulation. Use on steam, hot water, and process pipes and fittings.

Mineral Wool Pipe Insulation

Rigid and flame resistant, these insulation tubes are typically used in process piping and mechanical systems.

Chemical-Resistant Cellular Glass Pipe Insulation

Very rigid with a 0% water absorption rate, this insulation is unaffected by corrosive environments, organic solvents, and most acids. It is typically used in chemical-processing systems and underground lines.

ADA-Compliant Hot Water Pipe Covers

Reduce the risk of burns from accidental contact with hot pipes under your sink. These molded, flexible pipe covers are ADA compliant when properly installed.

ADA-Compliant Hot Water Pipe Cover Kits

These kits insulate one P-trap and two stop valves to reduce the risk of burns from accidental contact with hot pipes under your sink. The molded, flexible pipe covers are ADA compliant when properly installed.

Tear-Resistant Silicone Foam Pipe Insulation

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.

Clean Room Melamine Foam Pipe Insulation

These rigid, lightweight melamine foam tubes are wrapped in an ISO Class 5 and Fed. Spec. Class 100 clean room jacket that is suitable for sanitary and washdown applications. They’re typically used on cold and hot water piping and with refrigeration systems.

Lightweight Melamine Foam Pipe Insulation

Melamine has a lightweight construction that allows quick and easy installation. Use on cold and hot water piping and with refrigeration systems.

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.

Plastic Pipe Insulation Jacketing

Protect insulation from light impact and moisture with this durable PVC jacketing.

Metal Pipe Insulation Jacketing

Guard insulation from heavy impact and chemical exposure. This metal jacketing is corrosion resistant and often used outdoors.

Pipe Insulation Coatings

An alternative to jacketing, these coatings create a vapor barrier and protect from conditions outdoors. They are often used on irregularly shaped surfaces, such as fittings, flanges, and valves.
