Acoustical Insulation Blankets
Nonwoven acoustical insulation is ideal for high performance thermal and acoustical insulation applications. With minimal thickness and weight, these products provide very high acoustic absorption. They also have high internal integrity and are resistant to flammability.
Applications include: Vehicle trim acoustic treatments for door panels, HVAC sound absorption, instrument panel sound absorption
- Ultra-low moisture absorption <0.6%
- UL 94V-0 flame class rating
- Excellent dielectric strength shields against electrical surges
- Good chemical resistance
- Superior folding, bending, and scoring capabilities without cracking
