Knauf Faced Fiberglass Ecobatt R11 3.5"x23"x48"


EcoBatt batt insulation is a budget-friendly solution for enhancing thermal and acoustic performance in energy-efficient construction. These insulation products are versatile and suitable for use in both new and retrofit projects involving wood and metal frame applications in various settings, including residential, commercial, and manufactured housing structures.
For scenarios where top-notch thermal efficiency is crucial, you have the option of High-Density (HD) batts. These are particularly valuable when space is at a premium.
Our insulation product holds the GREENGUARD Gold Certification, ensuring it's formaldehyde-free and maintains high indoor air quality standards.
We take pride in our eco-friendly binder made from corn, sand, and recycled glass. It's naturally brown and doesn't contain added dyes.
Our insulation is designed to be soft to the touch, easy to cut, and less itchy, ensuring a comfortable installation process.
It is third-party certified to include a minimum of 50% post-consumer recycled content, making it an environmentally conscious choice.
Enjoy excellent sound control by using our insulation between floors and interior walls in spaces such as bathrooms, kitchens, laundry rooms, family rooms, bedrooms, and theater rooms, enhancing the acoustic environment in your home or building.
The StapleFree batt insulation variety consists of flangeless kraft-faced batts, which can be friction-fitted between 16" on center wood studs. This eliminates the need for stapling during installation, streamlining the process.
