Quiet Confidence for Clean, Modern Walls

This unfaced batt slips into a room like a whisper, dialing down noise while preserving crisp architectural lines. I love the slender 3.5-inch profile that nests neatly within standard 2x4 framing for a seamless finish. Pair it with smooth drywall and a soft matte paint to let textures and tones take center stage. It’s a subtle luxury that elevates everyday living through comfort and calm.
