Sound performance isn't about silence — it's about what your walls choose to let through. TimberHP's wood fiber insulation is dense, fibrous, and naturally sound-absorbing, which means it does the heavy lifting on both airborne noise (voices, TVs, traffic) and impact noise (footfalls, door slams) without bolt-on acoustic products.
The reason comes down to mass and structure. TimberBatt® packs roughly twice the density of standard fiberglass into the cavity, and its irregular fiber matrix scatters sound waves instead of letting them pass straight through. Add TimberBoard™ continuous insulation on the exterior and you also dampen the flanking paths that travel through the framing the noise leaks most assemblies miss.
The real-world result: quieter bedrooms, calmer offices, multi-family walls that hit STC targets without resorting to specialty assemblies. A wall built for thermal performance ends up sounding better too. That's not a bonus, it's how wood fiber works.
