Features & Benefits
- Ready-to-Use Product Features
- Features & Benefits
- Our composite foam is fiber-free, so you’ll have no handling issues.
- They are also easy to cut to any size and install. For further ease of installation, we offer a peel and stick (PSA) option. Just make the necessary field cuts, peel off the backing and stick the sheets to the substrate.
- Composite foam is the perfect choice for lining noisy enclosures.
- To create an effective sound barrier, all surfaces of the enclosure, partition or wall should be covered seamlessly.
- Reduces echo and reverberation.
- Blocks sound transmission.
- Reduce sound and noise from machinery.
- Excellent choice for creating soundproof enclosures and partitions.
- Improves overall acoustic quality, reduces stress and improves productivity.
- Reduces the transmission of radiated noise through the walls of duct work or piping.
Applications & Uses

- Product End Uses
- Process
The thicker, one inch foam should face towards the source of the noise to absorb sound within the space. Then the barrier layer provides a sound blocking layer to lower sound transmission through the panel. Then, the thinner melamine foam layer provides an airspace between decouple the panel from surface to which it is mounted.
- Installation Method
- These panels can easily mount to any wall or ceiling surface with water-based construction adhesive.
- Carefully make any cuts with a long blade utility knife or some type of reciprocating saw.
- Installation is best done at the end of the construction project.
- Use clean gloves to prevent soiling material.
- Melamine foam is fragile and should be handled with care.
- Maintain uniform temperature of minimum 60°F and maximum humidity of 40% prior to, during and after installation.
- Do not install material of unacceptable quality.
- Backing - Optional peel and stick.
