Sound Insulation

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.

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.

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

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

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.

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.

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.

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.

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.

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.

Easy-to-Hang Sound Barrier Sheets

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

Vibration Damping Sheets

Install these adhesive-back sheets to reduce noise from vibrating surfaces, such as duct and equipment housings.

Vibration Damping Coatings

Apply these coatings to irregular shapes and large areas and reduce noise caused by vibration. Keep applying coats until desired noise reduction is achieved.

Sound Barrier Panels

Set on top of ceiling tiles to prevent sound penetration.

Tape

Noise-Damping Velvet Tape

Low-pile velvet cushions surfaces and absorbs sound. Use it between parts and in acoustic applications.

Noise-Damping Foam Tape for Floor Joists

Quiet squeaky floor joists and reduce vibration with this foam tape.

Noise-Damping Foil Tape

Control the unwanted noise that comes from vibrating panels and support structures. This aluminum foil tape reduces vibration by converting it into a small amount of heat.

Rattle-Reducing Flocking Tape

Reduce rattles and squeaks between parts with this abrasionresistant flocked tape. The acrylic adhesive sticks even on hard-to-bond plastics.

Ultra-Conformable Foam Mounting Tape

The most conformable foam tape we offer, use this tape for mounting, gasketing, and damping sound and vibration. It has adhesive on both sides.

Light Duty Foam Mounting Tape

Mount lightweight signs and trim with this economical tape.

High-Bond Low-Friction UHMW Tape

Add a slippery surface to difficult-to-bond surfaces, such as plastic, foam, and powder-coated metal.

Antistatic Low-Friction UHMW Tape

Dissipate static and create a slick surface.

Low-Friction UHMW Tape

Cover chutes, packaging lines, and slides with this tape for a slippery, nonstick surface that resists abrasion and impact.

Shock-Absorbing Low-Friction UHMW Tape

Reduce noise and vibration in chutes, bins, and similar delivery systems with this UHMW-faced foam tape.
