Planning on doing some soundproofing? Think more insulation is all you need? Think again. There are four parts to better soundproofing, and adding insulation to absorb sound is just one. What are the other three? One is ?blocking? noise with a non-hardening caulk to close off airborne sound paths. Another is ?breaking? the sound path using resilient wood studs with metal clips. Last, but not least, is isolating and eliminating ?vibration? with special acoustical matting that isolates the wall structure from floor vibrations. You can get all four items needed, all together, in soundproofing kits for both interior and exterior residential walls. Besides blocking most noise transmission, one obvious benefit is better energy efficiency, with greater ?r? values. That helps both heating and cooling. If you're planning on doing some soundproofing, think insulation times four. Use them all and you'll keep noise outside and next door. And that's the On The House tip for today.
