Quiet Comfort, Tailored for 2x4 Walls

These R-13 EcoBatt batts wrap your home in a soft hush, refining comfort while maintaining a clean, modern build. I love the kraft facing—it streamlines installation and creates a crisp, tailored look behind the walls. Pair it with light wood studs and gypsum board for a serene, gallery-like envelope that keeps temperatures steady. It’s a discreet luxury—performance you feel every day, not something you see.


AI Review Summary:

Across retailer reviews, buyers consistently praise the batts for fitting 2x4 cavities well, expanding quickly, and producing less dust than expected. Many mention they cut cleanly and the kraft facing with printed measurements speeds stapling. Thermal performance is described as noticeable in previously drafty rooms, with moderate sound reduction. A few note compressed packaging requires a moment to fully loft and occasional batts arrive slightly undersized or with torn facing, though issues are uncommon. Representative quotes: “Easy to work with and install… would definitely recommend.” “Low itch and way less dust than others.” “One bundle had a couple batts a hair short, but still worked.”


Upgrade your 2x4 walls with EcoBatt R-13 and enjoy quieter, more efficient comfort—add to cart now.
