Quiet comfort, naturally refined

EcoBatt’s soft neutral tone melts into the architecture while elevating acoustics and comfort. I love its unfaced, friction-fit design—it slips neatly into 2x4 cavities and springs to full loft for a tailored finish behind the walls. Pair it with crisp gypsum board and slim reveal trims to craft serene, gallery-caliber rooms. This is the invisible luxury that makes spaces feel exquisitely calm and composed.

Saved my skin during an eczema flare up
This saved my skin! I had an eczema flare on my face, and my usual products weren’t working. A friend recommended the Avene brand and within 3 days of using this rescue barrier serum, my flare was almost completely gone! This saved my face!

PLEASE REVIEW — FORMULA CHANGED!!!
I wish I would’ve posted a review PRIOR to the formula changing but just know that I LOVED this serum. I’ve struggled with hormonal acne (PCOS) and eczema for as long as I can remember. Finally, last summer my dermatologist put me on (3) different RX including Spironolactone and Accutane. I was so tired so I stopped everything except for CeraVe cleanser, retinol (Tretinoin) and CeraVe healing ointment. My made up skin routine was working until I used too much Tretinoin and burned my face. I had read great reviews about this product so I thought, I might as well try it — and IT WORKED! I’ve been using this product for almost a year and I loved it. However, 3 weeks ago when I ordered it, I noticed the bottle had a green tint. I could tell after one use that the feel of the serum was different, more watery, not as thick as it used to be. The smell was also different. Still, I kept using it for nearly 2 weeks and I experienced 2 breakouts! Sure enough, I stopped the product and within a few days, my skin was back to normal. I am very upset because as someone who has extremely sensitive skin, this worked but unfortunately, the new formula isn’t for me.

Now I am using prescribed cream my dermotologist prescibed to try to heal the pigment issues this product caused. this product is a thick oil, NOT SPF 45-- TRUST ME you do not want this!!! See pictures i'm attaching to this review.
