ECOSE® Technology gives the product its unique brown color.

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 formaldehyde-free and have reduced global warming potential when compared to our products of the past.


Knauf Insulation Acoustical Smooth Board with ECOSE® Technology is a versatile product for thermal and acoustical applications such as office partitions, ceiling panels, interior panels and sound baffles.

Features and Benefits

Density and Size Availability

  • Knauf Insulation Acoustical Smooth Board with ECOSE® Technology is available in the densities and sizes required by panel and ceiling manufacturers. Special items not shown on the price and data sheet can be made based on our process capability.

Surface Smoothness

  • One surface is smooth which allows for flatness and uniformity.

Precision Tolerances

  • Tolerances are +/- 1/16" (1.6 mm) for thickness     and +/- 1/8" (3.2 mm) for width and +/- 1/4" (6.4 mm) for length.


  • The board is suitable for machining.

Noise Reduction

  • Excellent sound absorption characteristics, an important benefit for today’s office and interiors.

Indoor Air Quality

  • Certified for indoor air quality as a low emitting product by UL Environment GREENGUARD and the more stringent GREENGUARD Gold standard; also verified to be formaldehyde-free.

    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.
