Description

Knauf Sonic XP™ Duct Liner with ECOSE^® Technology is a flexible, mat-faced insulation bonded with ECOSE Technology. It is faced with a tightly bonded mat to give the airstream a smooth, tough surface, resisting damage during installation and operation. The encapsulant edge coating eliminates airstream flaring.

ECOSE Technology

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 fiber glass insulation products. ECOSE Technology reduces binder embodied energy and does not contain phenol, formaldehyde,acrylics or artificial colors.

Application

Specifically designed as an interior insulation material for sheet metal ducts used in heating, ventilating and air conditioning. Provides an optimum combination of efficient sound absorption, low thermal conductivity and minimal airstream surface friction.

Features and Benefits

• Low thermal conductivity.
• Fire-resistant, non-corrosive, durable and resilient.
• Tough, tightly bonded mat facing.
• Excellent sound absorption.
• Energy conservation.
• Better temperature control.
• Lowers operating costs.
• Greatly reduces noise from fans and mechanical equipment as well as cross-talk and air movement.
• Withstands damage from normal handling and shop abuse.
• If necessary, can be cleaned in accordance with NAIMA’s “Cleaning Fibrous Glass Insulated Air Duct Systems Recommended Practices.”
• Certified for indoor air quality as a low emitting product by The GREENGUARD Environmental Institute to both the GREENGUARD Certification ProgramSM 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%

Application & Specification Guidelines

Storage

• Inside storage is recommended.

Fabrication and Application

• Fabricate in compliance with the latest edition of NAIMA’s Fibrous Glass Duct Liner Standard.
• Liner shall be folded and compressed in the corners of rectangular duct sections or shall be cut and fit to assure lapped, compressed joints. Longitudinal joints in duct liner should not occur except at the corner of ducts. Longitudinal joints in liner shall be coated with adhesive. All damaged areas of the air stream surface shall be repaired with an adhesive which conforms to ASTM C 916.
• Liner should be adhered to the duct with 90% minimum area coverage of an adhesive which conforms to ASTM C 916.
• Mechanical fasteners should not compress the insulation more than ⅛" (3 mm), and shall be installed perpendicular to the duct surface. All fasteners should comply with the guidelines of NAIMA’s Fibrous Glass Duct Liner Standard and the Mechanical Fastener’s Standard MF-1-1975.
• Metal nosings shall be securely installed over transversely oriented liner edges facing the airstream at fan discharge, at access doors and at any interval of lined duct preceded by unlined duct. In addition, where velocities exceed 4000 fpm (1219 mpm), metal nosing small be used on upstream edges of liner at every transverse joint.

Limitations

• Knauf Sonic XP Duct Liner with ECOSE Technology should not be used in systems operating at velocities exceeding 6000 fpm (1829 mpm) or at temperatures above 250°F (121°C).

Fiber Glass and Mold

Fiber glass insulation will not sustain mold growth. However, mold can grow on almost any material when it becomes wet and contaminated. Carefully inspect any insulation that has been exposed to water. If it shows any sign of mold, it must be discarded. If the material is wet but shows no evidence of mold, it should be dried rapidly and thoroughly. If it shows signs of facing degradation from wetting, it should be replaced. Air handling insulation used in the air stream must be discarded if exposed to water.
