Acoustical Barrier & Thermal Insulators

We offer a variety of flame,smoke,and toxicity-rated silicone sponges and foams  that are used for sound deadening in high-temperature environments and are listed for volume resistivity per ASTM D257. We also offer a solid silicone rubber that is engineered specifically to block the transmission of sound and exhibits superior performance in low frequency noise reduction.

For ambient temperature conditions, we offer the lower cost Armaflex AP insulation and SC-41 neoprene, both closed-cell sponges. These low cost alternatives are not tested for their acoustical features like the silicones, but meet all FST requirements.

These are not extruded materials, but we can custom die cut or slit them into predetermined roll widths, and we  can also apply adhesive backing upon request.

AP Armaflex® A flexible elastomeric thermal insulation, black in color, with an expanded closed-cell structure for efficient insulation.

SC 41 Neoprene Closed Cell Sponge Soft density closed cell sponge supplied as precision die cut parts, slit goods, bulk materials with/without adhesives.

HT 800 A highly versatile, medium firmness silicone that offers the lightness of a foam with the enhanced sealing capabilities of a traditional sponge rubber.
