Durette Felt is a Nomex batting that is used in duct lining, pipe lagging, and barrier lay-up applications. Durette is Nomex fiber that is stitched into a "blanket" type batting material. Durette can be conformed to fit in and around many desired applications.

Cohrlastic is a flexible silicone, closed cell, sponge that is designed and used for vibration isolation mounting.

WILLTEC is an open cell Melamine foam, distributed under the SONEX name, which is used for noise attenuation. WILLTEC can be easily shaped, formed, and installed around existing equipment to assist with noise attenuation. Melamine foam will particulate if rubbed. Recommended application is within an enclosed Nomex Pouch. Additionally, WILLTEC is Class 1 rated for fire spreading and smoke density.

SOLIMIDE foam is a lightweight, open-celled, insulation foam that is designed for thermal and acoustic insulation. Usually yellow in color and will easily particulate when brushed or manipulated.

Barium Impregnated Silicon Oxide (BISCO) HT-200 is a mass barrier that is used to block sound waves. BISCO HT-200 is provided in various densities and is generally used to target lower frequencies. BISCO HT-200 can be used in conjunction with foams to achieve optimal performance.

Strip-N-Stick is a silicon sponge tape that is used to provide gasketing and vibration isolation. Strip-N-Stick is available with adhesive backing.

Damping foil composite is designed to reduce resonance vibration in thin sheet metal. It is constructed from lightweight aluminum bonded to a viscoelastic and pressure sensitive backing.

Nomex is a fabric material used primarily to encase materials such as sound absorbing foams. There are several acceptable nomex fabrics that are acceptable. Some nomex fabric weaves are porous enough to allow for noise to penetrate into and be absorbed by the foam while encapsulating any particulates that may shed from the foam.

Coroplast is a corrugated plastic sheet that can be used as a lightweight, rigid structure or panel to help isolate noise sources, to attach barrier materials to, or be the structure used to make mufflers out of. It requires a cover layer like approved aluminum tape on exposed surfaces.

Foamcore: n/a

BNR barrier material is another barrier material used on the noise control containment designs for the Russian airlock pump. This material is stiffer than Bisco wrap and is not recommended where flexibility is a desireable property.
