Open-cell spray foam insulation is a low-density, nonstructural insulation product. The tiny cells of the foam are not completely closed – they are broken. Air fills the open space inside the material, making the foam softer than closed-cell foam. It has many great performance features, including reduction of air infiltration, soundproofing, and durability. Open-cell spray foam insulation can also be applied in difficult-to-reach areas that other insulation cannot.


Knauf Insulation’s EcoBatt Insulation has ECOSE Technology, which holds the product together and gives its shape and color. It is plant-based and made with sustainable chemistry that replaces the traditional phenol/formaldehyde binder in glass mineral wool products. It is a cost-effective thermal and acoustical barrier, used in new and retrofit wood and metal frames, including walls, ceilings, and floors, plus anywhere where optimal thermal performance is required, and space is limited.



Knauf Insulation’s Jet Stream Ultra Blowing Wool Insulation is an unbonded, fibrous glass blowing insulation that provides optimal thermal properties and excellent coverage and blowing characteristics. It is used for open attics in new and existing structures, as well as in closed cavities with the BIBS system, where ventilation is not required.
