Types of Sound Absorbing Foams

Our other acoustic foams can be used for dock floatation and hull insulation, post insulation and corner padding, packaging padding and anti-static shipping, among other applications. Our current inventory of acoustic foams includes:

Buoyancy foams

Acoustic buoyancy foams are used in a range of marine and related applications where soundproofing and flotation are required in tandem. Install them below deck to keep a ship afloat while reducing noise, or on a floating dock. Our main products include Ultra Foam, a closed cell acoustic buoyancy foam that is lightweight and offers low moisture absorption and excellent thermal insulation. Also available are our rigid foam buoyancy billets, which are typically used for filling voids and improving flotation in docks, decks, boats, rafts and other vessels.

Expandable foams

Even with the best insulating materials, unwanted sound can creep in through door sills, A/C vents and small cracks in walls and ceilings. That’s where our expandable acoustic foams come in. Our products are specially formulated to quickly fill in unwanted gaps and spaces. Our main product is a two-part urethane foam that expands instantly and can be used with any polyester, epoxy, or vinyl ester resin.

Extruded safety foams

Extruded acoustic foams are an affordable way to close sound gaps, absorb unwanted vibrations and improve the overall integrity of a soundproof space. Use them on sharp edges, ceiling beams and other common structural features. Several shapes and sizes — including corner padding, edge padding, post foam and other configurations — are available.

Packaging and shipping foams

In addition to our acoustic foams, we also sell packaging and shipping materials that protect delicate items while in transit. Both regular and anti-static products are available — both of which are excellent choices for transporting delicate microphones and studio equipment, electronics and other sensitive items.
