M-DUCT

Features and Benefits

Knauf Air Duct Board-M systems provide good thermal insulation, vapor retardation, noise absorption, low leakage, and resistance to fungi and bacteria.

Energy Conservation

• Low thermal conductivity of 0.23 at 75°F mean temperature.
• Superior temperature control.
• Minimum heat loss or heat gain.
• Lower operating costs than sheet metal duct systems.

Quiet, Efficient Air Delivery

• Excellent acoustical characteristics reduce noise generated by air turbulence and mechanical equipment.
• Eliminates "booming" and "cracking" sounds caused by sheet metal duct contraction and expansion.

Condensation Control

• Assured insulation thickness, shiplap joints and FSK vapor retarder generally prevent condensation formation on ducts operating in unconditioned areas.
• This helps prevent moisture-stained ceilings and increases thermal performance.

Airstream Surface Durability

• Significantly more resistant to abuse than coated duct board products, giving extra protection against fabrication, installation and duct cleaning abuse.
• Highly resistant to bio-deterioration.

Airstream Surface Porosity

• Has an airstream surface which is 20% less porous to air than coated duct board products.
