Optimum Wall System

The OPTIMA system of fibre glass blow-in insulation is a thermal and acoustical insulation for sidewalls, cathedral ceilings, and other closed-cavity applications. The insulation is an unbonded, white, loose-fill virgin fibre glass designed for pneumatic installation behind non-woven OPTIMA fabric (or equivalent). This product can be used in the Blow-In-Blanket® System (BIBS®).

  • Blown in dry—immediately ready for drywall
  • Thermally efficient—fills voids for higher R-Values per inch
  • Excellent sound control
  • Little dust—quick clean-up
  • Uniform application
  • Won’t settle
  • GREENGUARD® Children & Schools Certified
  • Formaldehyde-Free
