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.

Features:

• 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 compliance.
• 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).
