Semi-Refractory Felt

Product catalog summary

Product Overview: Thermafiber® K-FAC® SR is a semi-refractory felt used for high-temperature insulation, suitable for service temperatures up to 1,900°F (1,038°C). It is non-corrosive, contains no asbestos, and is easily fabricated and installed. The product is ideal for high heat ovens, furnaces, and precipitators.

Specifications: The material has a nominal density of 14 lb./cu. ft. and is available in thicknesses from 1" to 4", with widths of 6", 12", and 24", and lengths of 36" and 48". It complies with several ASTM standards, including C 612 Type V Grade B and C 356 for linear shrinkage.

Installation: K-FAC SR can be grooved, routed, slotted, or die-cut to the desired size and shape. It is typically attached by impaling on pins or studs. Mechanical support is required for temperatures above 450°F.

Performance: The product withstands temperatures up to 1,900°F in static conditions and 1,400°F in dynamic conditions. It has a flame spread and smoke developed rating of 0 per ASTM E 84. Thermal conductivity varies with temperature, starting at 0.37 Btu•in/hr•ft²•°F at 300°F and increasing to 0.85 at 900°F.

Recommendations: For applications above 1,400°F, use is limited to static conditions to prevent insulation degradation due to vibrations. Initial heat rise should not exceed 15°F per minute to allow uniform binder dissipation.

Limitations: Not suitable for load-bearing situations or direct flame impingement. Custom sizes are available upon request.
