INDUSTRIAL NOISE CONTROL PRODUCTS
Quilted Blanket Absorber/Barrier Systems

The SMG line of barrier and quilted acoustical composites may be engineered to address a host of architectural and industrial noise problems. From addressing noise in manufacturing facilities to isolating mechanical noise in commercial or institutional buildings, these systems provide for the ultimate in noise reduction and isolation while resisting abuse and contamination.



FEATURES:
  • Superior Acoustical Performance
  • Abuse Resistance
  • Excellent Fire Hazard Rating (Class 1 per ASTM E-84)
  • Easily Maintained
  • Custom Fabricated to Meet Specific Site and Environmental Conditions

I-A Type I Nominal 2" fiberglass blanket quilted to a nominal 3/4" thickness. One side is faced with vinyl coated fiberglass cloth (VCFC), the other with a non-woven porous nylon scrim (NPS). Noise Reduction Coefficient (NRC)=.70

I-A Type II Two layers of nominal 2" fiberglass blanket quilted to nominal 1 1/2" thick. Both sides faced with VCFC integrally quilted to composite. NRC=.85

I-A Type III Same as Type II but with barrier septum, STC=26




OPTIONS:
Edge Trim: Edges bound with facing material
Grommets: Placed at edges for wall or ceiling mounting
Windows: Clear barrier vinyl windows stitched to barrier
Hook & Loop: To form tight vertical joints between blankets and/or provide access.
Colors: Gray, white, tan or black; decorative fabrics
Facings: Silicone treated facings for high temperature
applications (to +550(F)
Barriers: Optional 1/2 lb (STC=20) or 2 lb (STC=31) barrier septum
