Knauf Eclipse^™ Air Duct Board with ECOSE^® Technology


Description

Knauf Eclipse Air Duct Board with ECOSE^® Technology is used to fabricate rectangular or Max¹⁰ air duct systems. It comes with two stiffness ratings, EI-475 and EI-800. Both types are available with butt edge or factory molded male-female shiplap edges. The airstream surface of Knauf Eclipse Air Duct Board is treated with an EPA registered, anti-microbial agent that prevents growth of mold, fungus or bacteria in accordance with ASTM C1071, G21 and G22.

ECOSE Technology is a revolutionary new binder chemistry that makes Knauf Insulation products even more sustainable than ever. It is based on rapidly renewable bio-based materials rather than non-renewable petroleum-based chemicals traditionally used in fiberglass insulation products. ECOSE Technology reduces binder embodied energy and does not contain phenol, formaldehyde, acrylics or artificial colors.

Knauf Eclipse Air Duct Board with ECOSE Technology is designed for commercial and residential air handling installations for cooling, heating or dual-temperature service where good temperature control and noise absorption are required.

• Low thermal conductivity of 0.23 at 75°F (24°C) mean temperature
• Low installed cost insulated duct system
• Excellent acoustical characteristics
• Non-woven all-glass mat facing on airstream surface
• Assured insulation thickness, shiplap joints and FSK vapor retarder
• If necessary, can be cleaned in accordance with NAIMA's "Cleaning Fibrous Glass Insulated Air Duct Systems Recommended Practices."
• Knauf Eclipse Air Duct Board systems meet the fire and smoke safety regulations of most federal, state and local building codes
• Fabrication in shop or on jobsite
• Dark black glass mat airstream surface
• Certified for indoor air quality as a low emitting product by The GREENGUARD Environmental Institute to both the GREENGUARD Certification Program^SM and the more stringent GREENGUARD Children and Schools^SM standard
• Sustainability
• Carbon negative: meaning Knauf insulation products used for thermal insulating purposes recover the energy that it took to make them in just hours or a few days, depending on the application. Once installed, the product continues to save energy and reduce carbon generation as long as it is in place
• Fiber glass insulation with ECOSE Technology contains three primary ingredients:
• Sand, one of the world's most abundant and renewable resources
• Post-consumer recycled bottle glass
• ECOSE Technology which reduces binder embodied energy by up to 70%

• Fabrication in shop environment lowers field installation time
• One craft required to fabricate and install system
• Minimum capital investment for fabrication equipment
• Portability allows for assembly or fabrication at job site
• Black mat facing ensures a smoother airstream surface for a cleaner cut and added durability
• Lower installation cost than with duct wrap and duct liner with sheet metal
• Finished internal duct appearance is black
• Quiet, efficient air delivery
• Reduces noise generated by air turbulence and mechanical equipment
• Eliminates "booming" and "cracking" sounds caused by sheet metal duct contraction and expansion
• Condensation control
• Strong thermal performance
• Code compliance
