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.


Upgrade your walls with EcoBatt R-13 for quieter, more comfortable rooms—order your coverage today.

Nice shelves. Minor defect in one of mine.

Sturdy and easy to hang. Look nice. One of the set screw holes was off by 1-1/2” so I had to drill a new one, that wasn’t ideal.

Nice looking but bad quality and defects
Color: White, Number Of Shelves: 2, Size: 60 inches, Color: White, Number Of Shelves: 2, Size: 60 inches
Shelves look nice, but not great quality and one of my shelves came crooked (installed it perfectly level). Also has defects around the edges. Already installed so don’t want to rip off wall and return, but would like if they sent a couple new replacements at no charge. Keep you posted if that happens.

Sturdy, Stylish, and Easy to Install Floating Shelf
Color: White, Number Of Shelves: 1, Size: 35.4 inches, Color: White, Number Of Shelves: 1, Size: 35.4 inches
This floating shelf looks great and feels very sturdy once installed. It’s stable, fits securely on the wall, and holds plenty of items without issue. I measured beforehand, and it fits perfectly in the space I needed. The hardware was included, and assembly was quick and easy—I had it up in just a couple of minutes. The quality is excellent, and the clean design adds a nice touch to the room. Highly recommend!
