36 reactions · 11 comments | You should always be thinking “how can I reduce the sound coming from upstairs in my basement?” There are a number of different ways to go about this including: decoupling the ceiling with resilient channel or sound isolation clips, adding multiple layers of drywall with damping compound, or building double stud assemblies or floating ceilings. All of those work. But they’re also expensive and overkill for what most homeowners want which is to reduce the sound of footsteps, voices, or dropped toys upstairs. That is where this solution shines. By filling the joist cavities with mineral wool (such as this @rockwoolna AFB product), you’re doing the most important thing: killing the echo chamber. An empty joist chamber is basically a little sound amplifier. Sound goes in, bounces around, and comes right back out into your basement. The insulation served to absorb that sound where wood and concrete would otherwise block it. It turns that hollow cavity into a dead, quiet space. Does it kill 100% of all noise? No…the other solutions would assist with that. But for the cost, ease of install, and the net benefit, it is one of the best bang for your buck upgrades you can make before drywall goes up. We make this standard on every single one of our basement finishes because it dramatically improves how the spaces feels without blowing up the budget. This is the difference between how a space that looks finished vs one that feels finished. If you are planning a basement remodel, this is the kind of detail that is affordable to do early and frustrating (or impossible) to fix later. #basementremodel #basementfinishing | Platte + Pine Construction and Remodel | Facebook
