Knauf ECOBATT R-21HD b94ev

newmedia | Posted in Energy Efficiency and Durability on

Hello all, 

Is there anyone had experience with Knauf ECOBATT b94ev?
Does it smell? This is fiberglass batt. 

Thank you,

    Hi Jin.

    I don't have any experience working with this insulation, but I'm always interested in feedback on products, so I'm giving your post a bump. Hopefully someone who has worked with the Knauf Ecobatts chimes in.

    I've used it. I enjoy it.

    It doesn't smell.

    It's not quite fiberglass, it's made mostly from sand and recycled glass. Easy to put in and work with. The feeling is more dense than fiberglass but not as dense as rockwool.

    Hello Brian,

    I heard that this product smells a lot. If you read the homedepot reviews, one of the guys were saying he can smell "burnt baked brownies". Here is what he said.

    "I recently had Knauf insulation installed in my garage (2 walls adjacent to the house) and now 2 months later, I am still getting very strong smells coming into the house from the new insulation. The odor smells like burnt baked brownies and is very strong. I would highly encourage buyers to go with another brand/kind of insulation that does not give off any odor. I may need to gut my drywall again to remove this smell."

    I would like to know whether others had the same experience.

    Thank you,
