How to Soundproof Ceilings Between Floors

hey in this video we're going to address soundproofing between floors uh on a previous video I talked about uh soundproofing an entire room and preventing noise from escaping like from a home theater you know making sure the rest of the house is nice and quiet while you're cranked up and having your fun now what if you want the reverse well what are some of the examples uh in my life I had once the people living above me their kitchen was directly above my bedroom and I couldn't carpet upstairs cuz it was already tiled now let's say you for example are finishing your basement and you want a nice office or a nice quiet reading room and upstairs there nice hardwood floors you don't want to carpet that either so what do you do you dress it from underneath now there are two types of noise pollution I like to call it a sound okay there is like uh Airborne noises which are obviously you know come through the air talking music what have you and there's also impact noise which is basically vibrations through this joist and the wood you know easiest example is someone's upstairs either walking or dancing nothing's going to prevent that unless you do these following steps first of of all the Airborne noise we're going to use Rock Soul safe and sound okay that is going to prevent any music any singing any screaming kids what have you secondly as I said the impact noise that is caused by physics shall we say people walking on the floor vibrates the floor vibrates the joist vibrates your drywall so to to lessen the vibration we're going to use this this is called a resilient channel all right as you can see it's going to be almost independ from the joist you're going to tack it into the joist itself this is going to float independently and then finally you got your drywall and what you're going to do is you're going to screw your drywall into your resilient channel which is attached to your joist so by following these steps and attacking noise pollution two ways you should have a much quieter and a much more pleasant reading room all right so let's start soundproofing now the first thing you want to do step one is you want to look for any holes that might be in the ceiling that where Plumbing or wires might go through such as this this one here all right but that's an easy simple fix all you do is you take an acoustic ceiling like this you fill in the hole like that and we're done once you filled all the holes you're ready to install your rockol safe and sound all right now that we have sealed up all the holes with the acoustic sealant it is now time to put up the rockol safe and sound bat now remember this is not thermal insulation this does what the name implies safe and sound it stops Airborne sound from passing but the bonus feature is that because this product is made out of rock and slag which is a recycled metal it will not burn and it will not smoke that's the added bonus easy to install you just insert it you can press it and release now when we finish doing all the joys then we'll put up the resilient channel and the drywall okay so remember uh we are combating two types of noises we're Airborne noise and impact noise now the roxil safe and sound should cover the Airborne noise because it's doing what it's supposed to do but again we talked about impact noises and what is that that's when people upstairs are walking and the vibrations come through all the joist now in order to combat that we put this up this is called a resilient channel I put the first one up and I've marked the second one where I'm going to want it at 16 to Center and so line it up there line it up there okay and we just put it up with drywall screws oh one all right now once the rests are all up at 60 in the center that gives us our basically our VI vibration barrier shall we say and then we're ready for the drywall now when putting up the drywall there's really no point in putting up again against the joist because that defeats the purpose of what we are trying to achieve what you want to do now is you want to put the drywall onto the resilient channels themselves such as this also because this is a metal product you want to use fine threaded drywall screws there you go well let's attach the back one as well so remember seal the holes with an acoustic sealant put in rockol safe and sound add the resilient channels and you're ready for drywall and you should have a nice quiet comfortable reading room
