About Selecting Thermal Insulation

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

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.

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.

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.

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.

Pipe Condensation-Reducing Rubber Strips

Wrap pipes, tubing, and fittings to prevent condensation from forming. These strips are for use on copper, iron, and steel.

Spray Foam Insulation

Void-Filling Spray Foam Insulation

Cover large areas with this two-part expanding foam insulation.

Flame-Retardant Void-Filling Spray Foam Insulation

This two-part expanding foam insulation meets ASTM standards for flame and smoke and covers large areas.

Quick-Cure Spray Foam Insulation

Expanding quickly to fill large voids, this foam insulation begins to harden in 4 minutes and can be cut within 10 minutes.

Spray Foam Insulation

Fill cracks with this single-use can of expanding foam insulation. It hardens enough to be cut in one hour.

Insulation Sheets for Equipment, Ovens, and Furnaces

Polyurethane Foam Insulation
Sheets with Perforated Facing

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

Lightweight Melamine Insulation Sheets

The lowest-density insulation we offer, these sheets are made of lightweight melamine foam.

Crack-Resistant Rigid Polyimide Insulation Sheets

Even when subjected to heavy compression, these rigid polyimide sheets won't crack.

Abrasion-Resistant Silicone Foam Insulation Sheets

The fiberglass facing on these flexible silicone foam sheets protects against highly abrasive conditions and resists tearing.

Insulation for Freezers

Impact-Resistant Low-Temperature
Rigid PVC Foam Insulation Sheets

Made of rugged PVC foam, these rigid sheets absorb impact and restrict the absorption of water, air, and gas. Use in applications with operating temperatures below 32° F.

Moisture-Resistant Low-Temperature
Rigid Polystyrene Foam Insulation Sheets

These sheets resist the absorption of water, air, and gas and are widely used in cold-storage and packaging applications.

Sound-Absorbing Sheets

Use these sheets to quiet noisy areas and line machine enclosures. They’re made of humidity-resistant polyurethane foam and have a smooth, easy-to-clean facing.

Flame-Retardant Sound-Absorbing Sheets

This insulation meets ASTM E162 for flame retardance and ASTM E662 for smoke output. Use to quiet noisy areas and line machine enclosures. Sheets are made of polyimide foam.

Heat-Reflecting Sound-Absorbing Sheets

The foil facing reflects heat. Use these sheets to quiet noisy areas and line machine enclosures. They’re made of humidity-resistant polyurethane foam.

Oil-Resistant Sound-Absorbing Sheets

Either a urethane or polyester coating protects these humidity-resistant polyurethane foam sheets from oil exposure. Use them to quiet noisy areas and line machine enclosures.

Contoured Sound-Absorbing Sheets

Also known as egg crate, these sheets have peaks and valleys that absorb more sound at higher frequencies than flat-surface sheets. Use them to quiet noisy areas and line machine enclosures. Sheets are made of humidity-resistant polyurethane foam.

Easy-to-Hang Rigid Sound-Absorbing Sheets

Furnished with two hangers for easy mounting around your facility, these sheets quiet noisy areas. Made of melamine foam, they are peaked on both sides for good sound absorption in large open spaces.

Rigid Ultra-Sound-Absorbing Sheets

The best sound absorbers of all our rigid sheets, use to quiet noisy areas in your facility. They're peaked on one side for more sound-absorbing area than flat sheets. Made of melamine, they have an acrylic resin finish that resists dust and dirt and wipes clean.

Water-Resistant Rigid Sound-Absorbing Sheets

These polypropylene foam sheets will not degrade if exposed to moisture and occasional salt water spray. Use them to quiet noisy areas and line machine enclosures.

Flame-Retardant Rigid Sound-Absorbing Sheets

Made of melamine foam, these sheets meet UL 94 V-0 for flame retardance and ASTM E84 5/20 for flame and smoke. Use them to quiet noisy areas and line machine enclosures. Sheets are peaked on one side for more sound-absorbing area than flat-surface sheets.

Sound Barrier Sheets

Reflect sound and block noise from traveling to other parts of your facility.
