Equipment Liner M

Equipment Liner M

Knauf Equipment Liner M with ECOSE® Technology is a natural brown flexible glass mineral wool blanket with a black mat facing adhered to the air stream side. The product provides thermal and acoustical insulation while providing a smooth, tough air stream surface which resists damage during installation and operation.

ECOSE® Technology

ECOSE technology is a revolutionary binder chemistry that enhances the sustainability of our products. The “binder” is the bond that holds our glass mineral wool product together and gives the product its shape and brown color. ECOSE technology is a plant-based, sustainable chemistry that replaces the phenol/formaldehyde (PF) binder traditionally used in glass mineral wool products. Products using ECOSE technology are formaldehydefree and have reduced global warming potential when compared to our products of the past.


It is used to provide noise reduction and thermal insulation for equipment air conditioning, heating) where air erosion resistance is required. The product is designed for systems operating at temperatures up to 250°F (121°C) and velocities up to 6000 fpm (1829 meters/min).

Features and Benefits

  • Low emitting for indoor air quality considerations


  • 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.
  • Glass mineral wool insulation with ECOSE® Technology contains three primary ingredients:
    • Sand, one of the world’s most abundant and renewable resources
    • A minimum 50% post-consumer recycled bottle glass
    • ECOSE® Technology which reduces binder embodied energy by up to 70%

Indoor Air Quality

  • UL Environemnt GREENGUARD Certified
  • UL Environment GREENGUARD GOLD Certified

Glass Mineral Wool and Mold

Glass mineral wool 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.
