Duct Board



Part No. T0475

Duct Board is a rigid, resin bonded fibrous glass board with a tough, damage-resistant, flame retardant, reinforced aluminum foil (FRK) facing. When fabricated into duct systems, it combines excellent thermal and acoustical insulating properties with substantially airtight transmission of air.


  • Virtually eliminates air leakage thus saving heating and cooling costs
  • Assured thermal R-value performance
  • Absorbs noise and reduces popping noises caused by expansion, contraction and vibration
  • Thermal/acoustical insulation board plus jacket forms a single component duct system, thus reducing inspection time
  • Lightweight boards are easier to transport and handle than insulated sheet metal ducts
  • Bacterial and fungal growth resistant with an EPA registered biocide that protects the air stream surface from microbial growth Standards, Code
  • Meets NFPA 90A/90B
  • Meets ICC International Mechanical Code, Corps of Engineers Guide
  • Spec., NYC MEA #186-69
  • Supported by NAIMA and SMACNA industry standards
  • Meets requirements of ASTM C1338, ASTM G21 (fungi test) and ASTM G22 (bacteria test)
