About Selecting Thermal Insulation

Heat-Reflective Curtains

The aluminum on one side of these curtains reflects radiant heat.

Flame- and Heat-Resistant Curtains

These curtains are for intermittent contact with flames and hot surfaces.

Flame- and Heat-Resistant Blanket Rolls

Flame- and Heat-Resistant Blankets

Blankets are for intermittent contact with flames and hot surfaces.

Flame- and Heat-Resistant Panels

Equipment Markers

Mark equipment at risk of being hit by vehicles.

Sound Insulation

Easy-to-Hang Sound-Absorbing Sheets

Grommets along one side make it easy to install these sheets around your facility and quiet noisy areas. Made of vinyl-coated fiberglass, they resist abrasion, oil, dirt, moisture, and most solvents.

Sound-Absorbing Cylinders

Hang these nylon-covered fiberglass cylinders in areas with high ceilings to absorb sound from all directions. Each cylinder is equivalent to 10 to 15 sq. ft. of acoustical ceiling tiles.

Easy-to-Hang Sound Barrier Sheets

Suspend these thin sheets to reflect sound and block noise from traveling to other parts of your facility.

Sound Barrier Partitions

Set up these free-standing partitions to reflect sound and block noise from traveling to other parts of your facility. A vinyl barrier is sandwiched between two vinyl-coated fiberglass absorbers.

Sound Barrier Sheets

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

Thermal Insulation

Thermally Stable Composite Paper Insulation Sheets

Made of flexible composite paper, these sheets won't shrink or lose shape in the high temperatures of air furnaces and hot water tanks.

Fiberglass Insulation Sheets

These lightweight flexible fiberglass sheets are typically used to insulate equipment and appliances.

Flexible Fiberglass Duct Insulation Sheets

Wrap rectangular and round ductwork with this flexible insulation.

Fiberglass Pipe Insulation

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

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.

Rigid Fiberglass Duct Insulation Sheets

Insulate rectangular ductwork.

Fiberglass Building Insulation Sheets and Strips

Also known as batts, these fiberglass sheets and strips are used to insulate walls, ceilings, and floors.

Heat Barrier Sheets

Protect equipment and surfaces from radiant heat. These flexible sheets have an adhesive back for installation.

Fiberglass Weld-Backing Tape

Stick this flexible tape to the back of welding seams to contain spatter and prevent oxygen, water vapor, and other gases from weakening the weld.

Fiberglass Pipe Flanges for Corrosive Chemicals

Flanges have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. Use in metal surface treating applications, plating solution lines, and other chemical process applications. They are reinforced with fiberglass layers for better strength and durability than any of our other pipe flanges for chemicals. Bolt two same-size flanges together with a gasket to create an access point within a line.

Drain Vents

Mount to the outside of your enclosure to prevent moisture from being trapped inside.
