EcoBatt® Insulation

EcoBatt® Insulation

The brown color comes from ECOSE® Technology, a revolutionary, new sustainable binder born from five years of intensive research. Based on rapidly renewable bio-based materials rather than non-renewable petroleum-based chemicals commonly used in other insulation products, ECOSE Technology reduces binder embodied energy by up to 70%, and does not contain phenol, formaldehyde, acrylics or artificial colors used to make traditional fiberglass insulation.

EcoBatt Insulation combines sand, one of the world’s most abundant resources, post-consumer recycled bottle glass and ECOSE Technology to create the next generation of sustainable insulation…naturally from Knauf Insulation.


Knauf Insulation EcoBatt Insulation are thermal and acoustical products made from highly resilient, inorganic glass fibers bonded by a thermosetting resin. The products are available unfaced.


Knauf Insulation EcoBatt Insulation products are cost-effective thermal and acoustical barriers for energy-efficient construction. Their consistent quality, low dust, and clean-cutting resilient fibers make fabrication easy and installation fast. The products can be used in new and retrofit wood and metal frame applications in residential and commercial structures, as well as in manufactured housing applications. These applications include thermal and acoustical treatments to walls, ceilings, and floors.
In addition, High Density (HD) batts are available where optimal thermal performance is required and space for insulation is limited. High Density Cathedral Ceiling Batts, for example, deliver greater R-value in less space, so builders can increase R-values and still maintain adequate space for ventilation.


Knauf Insulation offers a full line of standard and high-density batts and blankets with a wide range of sizes and R-values. Available unfaced Knauf Insulation's residential insulation can be used for cavity walls, floors, ceilings, attics, basements, and crawl spaces. It is highly resilient, recovering quickly to full thickness. It also greatly reduces the transmission of noise in the house.

Light Commercial

This full line of standard and high-density batts and blankets for wood and metal frame construction is available unfaced. Knauf Insulation products can improve STC ratings in wood stud construction by 3 to 5 points and in metal stud construction by 8 to 10 points, depending on the complexity of the wall configuration and layers of insulation. Knauf Insulation's commercial building insulation can be used for exterior and partition walls, floors, crawl spaces, and a variety of ceiling applications.

Manufactured Housing

Knauf Insulation Manufactured Housing Insulation is a full line of batts and blankets with a wide range of R-values, lengths, and widths. It is designed to work efficiently with pre-manufactured structures of all widths. It can be used for cavity walls, floors, and ceiling applications.


Knauf Insulation's full line of retail batts and blankets comes in a wide range of sizes and R-values, and is available unfaced. This highly resilient insulation recovers quickly for a snug fit and assured thermal performance. Knauf Insulation's retail packaging has easy-to-identify R-value and application information to help your customers find the right product quickly.
