Sound Barrier Sheets

Stop noise from spreading to other parts of your facility—these sheets reflect sound back toward the source.

Plain-Back Melamine and Fiberglass—Have an additional layer to reduce noise within an area. They can be used to line machinery enclosures.

Melamine Foam—The highest temperature resistance of all the choices.

Fiberglass—Strong acoustic performance at a lower cost per square foot than other materials.

Polyurethane Foam—An economical option for general purpose noise control.

Clean Room Lightweight Melamine Foam Pipe Insulation

Limit contaminants in clean rooms and sanitary environments. The jacket on this insulation meets ISO Class 5 and Fed. Spec. Class 100 clean room standards, so it won’t shed particles. It’s also washable, making this insulation good for stainless steel process piping and clean steam distribution systems that undergo frequent cleaning. In addition, the lightweight melamine won’t overload supports on overhead piping and long runs.

Slit Tubes

Ready to fit over straight pipe sections. Just pull open the insulation, snap it around your pipe, and seal it closed with the adhesive strip.

Sealants—Close gaps, seams, joints, and punctures in your insulation.
