Step 1:
Air seal your walls & attics with EcoSeal Water-Based Elastomeric Sealant.


Step 2:
Properly insulate your attics with Jet Stream® Ultra Blowing Insulation.


Step 3:
Properly insulate your walls with Jet Stream Ultra or EcoBatt® Insulation.



Knauf Insulation EcoSeal®
Water-Based Elastomeric Sealant

EcoSeal dries to a flexible but tough film that forms an effective, continuous and affordable air barrier in the penetrations and joints of your building envelope, including exterior walls, attics and floors. EcoSeal is easy to use and cleans up with water, so all you have to do is spray and walk away.

Knauf EcoBatt® Insulation

Knauf EcoBatt Insulation installs quickly and easily while being less dusty and friendlier to the touch. It delivers greater sustainability and thermal performance that’s assured for life. Today, building green is even more of a priority, and Knauf EcoBatt Insulation delivers better overall performance than ever while at the same time being better for the planet.

Knauf Insulation Jet Stream® Ultra Blowing Insulation

Jet Stream Ultra is the ultimate blown insulation solution for thermal, acoustical and energy efficiency in your homes . Designed to work for both attic and wall applications, it fills even the smallest nooks and crannies.

When you seal your homes with the EcoSeal System, you get:

More than 40% post consumer recycled content. A typical home with the EcoSeal System will contain the equivalent of 2700 recycled bottles — saved from the landfill.

Acoustical Performance. STC (Sound Transmission Class) values that beat foam1.

Air leakage resistance. Exceeds EPA Energy Star requirements2.

Limited lifetime warranty. Gives your customers peace of mind.

ECOSE® Technology. A revolutionary new binder based on rapidly renewable bio-based materials instead of non-renewable chemicals like phenol, formaldehyde or acrylics.

Out of package assured R-Value. Not subject to variations in foaming conditions.

No degradation of thermal resistance over time. No settling and no off-gassing.

More for your money. The EcoSeal System can deliver a sealed and insulated 2 x 6 wall for less money than a 2 x 4 wall insulated with open cell foam3
