Economical, Easily Applied
A low-cost preformed mineral-fiber felt for thermal, fire protection, and sound control applications. Fine-fiber, semi- rigid composition makes Thermafiber Industrial Felt easy to handle. Foil, ASJ, or glass scrim facings are available. Fiber can be wrapped with Mylar or polybagging.

Fire-Rated Performance
Rated noncombustible, as defined by NFIPA Standard 220 when tested in accordance with ASTM E136. Melting point exceeds 2,000F., and the product withstands ASTM E119 temperature for over 5 hours when mechanically supported. Not for service operation at this temperature; refer to table for recommended maximum hot-surface temperature. Surface Burning Characteristics: flame spread 15; smoke developed 0, per ASTM E84.

Nonabsorbent, Corrosion-Resistant
Thermafiber Felt absorbs less than 1% moisture; will not corrode steel or aluminum as tested per HH-1-558B.

Wide Range or Applications
Because of a high melt point and 11 densities, Thermafiber Felt is adaptable for commercial and industrial applications in a broad scope of cold to hot or low to high temperatures.

Thermal applications--commercial and industrial ovens, package boilers, dryers, kilns, tanks.

Fire-protective applications--metal fire doors, light fixture protection, ship bulkheads.

Sound control applications--metal partitions, sound booths, acoustical decks, silencers.

Fabrication--7.0 HB cuts easily into a variety of shapes for pipes, elbows and other fittings.
