Soundproofing A Room (It's Easier Than You Think)

hey guys Jeff welcome back to our basement Series today we are starting the process of soundproofing the theater room we've got to build some walls we've got to do some insulation we got to get our green board up but first gotta grab the putty pads that's right the first step in sound proofing is stopping air transfer and whenever you've got electrical you've got to seal those boxes up real tight so you either use plastic boxes and a little spray foam or you use putty pad around your metal boxes my electrician installed metal so padding it up we're going to show you how to apply these things so you can get an air seal around all of your boxes listen here's the system you peel off plastic from one side so that you can keep clean and wrap this bad boy up we're going to stretch it out as we go make sure you get all around the back of it there we go seal up your wire protrusions there we go try to keep it nice and tight to the box so you're not going to affect your drywall installation there we are okay yeah one pad per plug all right don't try to be cheap this doesn't stretch like putty it's a little more dense than that so you're only going to get one pad on each one of these electrical boxes and if you have a big double box you're going to need two pads for one of those as you can see this is our 20 fiberglass insulation it is the next gen fiberglass though okay so I recommend wearing some kind of a mask when you're working with it but the reality is you can see a couple fibers flying around for the most part this stuff is non-itch okay it is a lot nicer to work with than the old Generation stuff you're going to want to put an R20 or at least an R14 bat in the wall it's okay if it gets compressed we're looking for Mass not for thermal brake so if you put an R20 installation here and it compresses because R20 is for a 2x6 ball you put it under compression that's okay because you have the same mass in the wall we're going to just fill up all of our cavities and that's going to be step one so Step One is this in the wall and the ceiling though we're going to go double layer we want as much mass as possible when we're thinking about an acoustical environment and that's why we're going to go two layers in the ceiling one in the walls and then we're also going to be adding the sauna fan there's two other issues I would just point out real quick one is the insulation now I know that there's lots of people on the market and they will talk about using mineral wool for doing soundproofing and yes it works but I'm going to say that this is 95 as effective and half the price call me cheap but I'm going to be using this for the rest of my life right this is also next gen so it's easy to work with doesn't make your arms itchy or anything so it's pretty cool now you put in two layers okay you want to stagger your joints because soundproofing is all about managing the movement of air and if you can eliminate air movement and then you add Mass on top of that you get a really effective sound barrier so what we're going to do here is we're going to finish strapping the ceiling and then we're going to be installing our sauna pan green board and then the secret to success here because my client wants pot lights and when you're sound proofing this room you have to create a layer of sound proofing and then you have to build inside that so what we're going to do is after we get the green board up we're going to actually strap the seedling again with two by threes so create an inch and a half space so we can drill out the location for the pot lights and after the green board is up the electrician's going to come back and run the wire for the locations and then we'll come back in here we'll install the drywall drill the holes and all that wiring will be on this side of the soundproofing barrier and so our drywall is going to be fire rated and that will have lots of mass in it and that'll be part of the solution but the green board isn't going to have any holes or any air leaks and that is going to make the biggest difference in that transfer of noise from this room upstairs [Music] all right now the strapping is up quick tip when we put our board up we're going to want to know where the strapping is over here I didn't use a laser level to install this it's just to get the material up in the air so I'm going to make a mark with a marker middle of all these strappings it doesn't matter if you have plastic or paper faced insulation just Mark your wall even the top of your frame sometimes will work easily identify where you're going to start and then over here at the edge of the board you can tell right makes life simple we're going to use the drywall lift to throw this up in place traditionally when I'm working in these environments I don't trust the walls or Square I'm curious though because the nature of this panel I would love it if this was Square make my life so much easier right so we're going to give it a try but generally what I do is I'll measure Off the Wall 45 46 inches and then I'll install the second piece and then I'll measure back and then cut it and install the first piece usually the only way to get that angle perfect we'll see if we can get lucky now this is my sauna pan insulation panel currently being sold at Home Depot in Canada with very limited availability in the United States you want to get this product where you live you got to scream and yell a little bit and let them know that you're really interested in it I'm going to go this way keep these feet against the outside wall and there we go we'll just drive this over we'll check the framing well actually that's not bad there I might get lucky I'm going to back it up a little bit I got to get past my 2x4 on the wall and the screw all right wow I got lucky all right now remember the reason I went quick and simple and dirty here is because I'm going to add another layer of strapping underneath all this after the wiring is run and I'm going to go with a full sheet of drywall from end to end so I'm not concerned about situations like this I'm not going to take the time to put more strapping up here I'm going to screw at that location right and the board will be held in place and then we'll install the next piece and so on and so on we'll stagger our joints won't be a problem at all we're using a 1 and 5 8 drywall screw to go through the one inch board and a three-quarter strap if I install the screw head flush I guarantee I can't puncture any other wiring or Plumbing or anything else that's in the ceiling that's being hidden by the insulation and that is plenty of grab [Music] just want to get it up there snug as a bug in a rug I'm just going to throw about 12 screws for each panel the less Fasteners the better at this stage because every Fastener is made of metal and will transmit sound so less is more I'm going to stick about 12 and I'm going to throw up a few more panels and show you how to stagger these joints we'll just jump into a time lapse real quick [Music] I'm going to save you all the Gory details of watch me install every single piece but I'll show you this just make sure you measure off where your heat ducts are okay and then you can draw with a circle with the marker working with this stuff markers your best friend you can draw a circle where your heat run is grab a handsaw this is a drywall saw okay and it is gonna run you slower than drywall don't be frustrated okay it is a very densely packed fiber but it will get the job done or you can use a cutout tool again this kind of dust is brutal you probably want to have a mask on again that's not the tool that's the density of the material you'll get it done there we go now once I get all the seedling in we'll just come back into camera we'll talk about getting the walls installed and how we're going to seal the gaps between panels because you'll notice right over here there's a 1 8 inch Gap I didn't get the panel perfectly squared off but I'll show you the secret for closing up those gaps the materials you want to use and all the rest of the board we want to finish the ceiling and then get the walls on all right so that we're creating an overlap other than that it's pretty straightforward my job today is to get the rest of the screen board on so that the electrician can come and do his job later all right so next day we had the electrician come in and he ran the loops for our lights but I just wanted to walk through the assembly here just to make sure that we're all clear we'll start up here in between the joist cavity two layers of our 20 fiberglass pink next-gen insulation and then we use a 1 by 3 strapping nailed to the joists and then the green board is screwed to the strapping and slightly I'm talking six State screws per sheet four by eight and then we strapped over top of the strapping with a three inch construction screw through a two by three then we ran the wiring this wiring is actually stapled to the side so it's up to code this will get tucked in like this when we put the drywall on and then when it's time we'll install drywall to this and then we can drill out the hole connect the wire to the Box tuck it up the hole into this little cavity space here that gives us the green board 100 continuity on the ceiling it'll also give us the ability to bring the sound board right up to the side and encapsulate the room all the walls the ceiling is going to be green board to green board and then we can use an acoustic sealant or a spray foam for any small gaps or cracks to get rid of any air leaked possibilities and this is how you get pot lights in the ceiling and keep the sound down if we put drywall right directly over top of the green board I'd have to drill that out too for every potlite and those six holes would eliminate all of the work that we put into this room I know it sounds like a lot of work a lot of material but you're either going to get it right or you're not you want a really quiet soundproof room you got to go with that kind of Integrity okay I know in school they don't do any favors they tell you 50 to pass 80 makes you a genius but in a construction situation like this you have to be somewhere between 99 and 100 of what you do it's all about doing it right it's Integrity there's no such thing as well I did sound proof 85 no that'll be noisy as hell no we got a couple of other issues here I wanted to show them the electrician brand wire and then he closed up again that was nice looks like a crime scene I want to bring your attention up here and I'm going to open up this cavity here a little bit but I'm going to cut on the stud so I can tape it up really easily afterwards all right look at this Gap the insulation fell when you're working if you see something like that stop what you're doing because that's the outside that's going to be cold air in the winter time and that's going to have condensation that's going to make the insulation wet which is going to destroy the R value year after year after year it gets worse worse worse then the studs start to rot then the mold starts to show up this is what we're dealing with in construction we can't have that that's my exterior well now you'll see that around here they've got this purple foam when they built this house before they did the installation and the rim joists they did a thin layer of spray foam around the entire room joist just to create that perfect air seal on that part of the house but this should be lifted back up into position because I know it fits I just know that whatever happened it's slumped and just because I'm going to make sure I can't afford to have an issue here double check Yep this one's slumped too there we go now we got good contact you've got 11 electrician because they do a great job of meeting an electrical code but when they're fussing around with your Vapor Barrier and your insulation make sure you follow up that everything is still closed up properly that one little dark space behind the plastic is going to end up destroying all the work in this room [Music] for the record when you're opening up a wall if you cut in the middle of the joist you have something behind it to put pressure on to get a good seal and if you cut straight you can repair something rather simple without having to use a whole roll of tape now when it comes to doing Lighting in a theater room you've really got two options you're going to see real common in a lot of theaters they're going to have like wall lights like sconce because you can have a box you can putty pad it and it generally it's a pretty decent way to seal it up in a ceiling however if you want pot lights there's two ways to do it you can create a box that your pot light can be cut into out of the green board really five-sided box or you can install all your green board nice and tight and then you can run another layer of strapping that's a two by three because what this does is it gives you something you can staple you can Staple in the side run your wiring and then what you've got is a place where your wiring can go while you're drywalling and then you can drill your hole and then you can wire your device box you can put it up through the hole slide it to the side and then install your pot light and you're not breaking through your sound barrier having a continuous barrier of sauna pan is the secret to success here okay so remember if air moves sound Travels by sealing all of this up really good and then dropping the ceiling another inch and a half I know everybody's like oh but the space nonsense if you're gonna go for soundproofing the most important thing is the sound everything else gets sacrifice in every decision you make so complete layer of sound and pan and then we're going to seal it all up so what I'm gonna do I'm going to throw a couple panels on the wall I'm going to show you how to seal it up properly that way you're ready to roll thing about this stuff is it is super lightweight kinda it weighs about the same amount as a sheet of drywall we're going to install this with one and five eighths drywall screws that is going to give us all of the support we need we don't want to use too many screws okay we're literally just talking about the perimeter something to keep it in place when the drywall gets installed we're going to use a two and a half inch drywall screw and that'll finish connecting everything the less pieces of metal you have in the wall the better off you are we just want to have enough to hold this in place and to hold the board in place so that I can rotor zip out the window that's right you can use a drywall cutout tool on sauna pan to cut everything out of the way these fibers are pretty hard on the mouth wear a mask when you cut it and this is where we're going to run into problems right because whenever you build a fluid it's never as tight a seal as you'd like it to be now there are two ways to seal up gaps and air movement one of them is just this the black goop this is called the acousta seal and you will know this if you're in the business it's a product we use with a vapor barrier it's how we seal the plastic to wood or plastic to metal framing even and it works like a charm in this scenario as well so you want to treat this like a cocking you want to all of your joints it's that simple that gets rid of any of the air that passes between the boards now this stuff doesn't dry so you put a nice thick bead here okay and you don't wipe it in you don't worry about it you don't tool it you don't finger it okay let's get it in get it on and get it done all right and this is a little bit messy when that's fine we're not going to get our knickers in a knot over that okay bam okay that's way number one second option is if you have holes you can use expansion foam now don't expect everybody to have a fancy gun so I'm not going to show you that but I've got a gap right here and this board is because of the roof and compression I'm not a big fan so what I am going to do instead of using caulking in the middle of the room and having a black goo everywhere I'm just going to use the foam it's under compression and it's slow I mean it's the more pressure you use on the tip the more foam comes out right so you should be able to keep this inverted oh brand new cans sensitive here we go nice gentle bead the trick with this is having the can as upright as possible so that you're not just pushing all the gas out of the can here we go the combination of these two products will work to seal up every one of your gaps I know it's a labor of love right but when it comes right down to it when you're soundproofing you can do 95 soundproofing and it's no different than 50 okay so if you're gonna do it at all use every ounce of Integrity that you got in your body and seal every Gap and crack all right once you've got all that done you're ready to hang drywall all right so before I tackle the heat I just wanted to do with this mess yep that's not useful at all I'm all for having a little extra wire it's nice if you're wiring to be able to work down here instead of over your heart because that makes life a lot easier having them the same length is going to help with that I don't have 10 pounds of wire hanging down out of that ceiling I can manage installing drywall in that scenario there we go okay now moving on here's my duck this hole is cut pretty much exactly to what I need but that's not really what I want to go for I want to have a bigger hole so I can actually get a drill in there and add a screw later and I've got to get my tools in here to crimp this so I'm going to cut the hole much bigger than I need and then we will kind of come back with spray foam to finish that off there we go okay I'm on wood here yes I am God bless it all right here we go okay now this duct it's just not moving anywhere oh here we go we can go to here good then I can screw it and then stick it back up here's a 30 tool everybody should own this is crimpers it's uh three blades on Two And basically what we do here I'll start on this side as you take a six inch pipe and you make it just a little bit smaller by crimping it so it's the same amount of material but it's zigzagging back and forth it's like driving through the country on a highway versus a road that goes around the river or a lake right it takes forever zigzagging around this shortens the distance of the diameter of this pipe so that I can slide an existing pipe over top I could have crimped the metal that I'm going to use as my extension and suck it in but then I'd be causing resistance right at the last point and we don't want that so by crimping the pipe in the ceiling I'm not interrupting with the airflow or the efficiency of the system boom nice now I got a little six inch extension because what I'm doing is I'm calculating my extension from the green plus my framing plus 5 8 drywall plus the fact that this will squeeze up okay bam there we go now that is a nice piece of ductwork and because I'm hanging nice and low here I'm going to get either one of the right screws or change my bit I've got two of the boogers here all right that's right there there we go one on the other side here good now see how much height we get there we go so now when I go and install my drywall it'll be sitting on the duct okay and it'll have resistance which is perfect so that when I come back with my RotoZip tool I just go ahead and find the edge skip it and zip it that's problem solved there we also have a problem in the corner dealing with the plumbing so let's go tackle that Miss now you'll notice that the way they got this hooked up here they're not using a frost free line so they're using a quarter turn shut off valve and then a bleeder valve now when you turn the water off and you open this up it lets whatever water is in that line drain back into the room which could be a little messy so have yourself a pail but it's one way to guarantee that there's no water in your hose bib the other way is you turn it off go outside get a vacuum and like literally vacuum the line right out okay now what we're going to do is I'm going to put a first piece of green board here 26 and three quarters is my measurement I've already checked the entire bulkhead is all perfectly straight so we're just going to cut a few of those but for now 26 and three quarters okay let me show you how to cut sonopan green board with your olfa knife you want to go to the second line on your blade that's the perfect depth lock it in use your drywall Square get a score all right move that out of the way watch the magic happen now you start the top buried right in there use a little bit of force done that's about as pretty as it cuts okay don't get worked up over the details if you want it prettier on the back side you got to cut it a little bit more and then you're gonna end up scoring the Sheep behind you we only got a bit of a scratch the secret here is we're going to put this up and I want to have a hole in this board right where I want to be reaching up so let's go 11 inches in the middle 13. yeah it's right in the middle 11 inches this way that's my middle okay now to make this effective we have to remember the end from the beginning we're going to be putting our drywall over top of this I can put a nine inch door on it which is an eight by eight hole so there's four there's eight there's four there's a so there's my hole that's for the drywall now if I make an eight inch hole here then I just need to get myself like a 12 inch piece of green board that I can rest on top after I install this part of the soffit that makes any sense if not just keep watching we'll show you what we do here we go same thing foreign make a trap door done all right in case you're wondering a 26 inch span is perfectly acceptable when you're working with 5 8 rival the reinforcing of that drive of that fiber makes this really doable all right and this is why God invented showers all right and make sure we're flush here okay okay now I got my trapdoor and my sauna pan I'm going to use a two and a half inch screw right here in the middle and so when you reach up acts as a little little little door handle so as long as that screws in the middle you know you're going to have a good good seal okay there we go so now we've got our green board in place we've got an ability to access that we know when we put our drywall over we're just going to cut an 8x8 hole here that's problem solved we've got the ductwork solved we got that solved I think now it's time to throw up our first sheet of drywall but first before the drywall I've got to put a couple more pieces of the green board on the soffit one step at a time Jeff don't get ahead of yourself we want to have a nice tight seal here so we'll get another piece underneath a couple pieces on the side and we'll jump into some drywall you'll be able to see the whole assembly come together really well then now for everybody who has an issue with a window like this this is actually it looks like is it one and a quarter inch yeah one and a quarter inch Framing and then my board comes right to here okay I'll give you an idea what's going on we can see our concrete foundation one of the best things you can do is take your green board right up against that that way you actually have a thermal Bridge here as well up against your concrete so you don't have your drywall in contact with your masonry if I just go back here with drywall or all wood I don't have a thermal brake anymore because wood is a lousy insulator when it's that thin so I'm going to use the green board and then I'm going to go 5 8 over top it's going to come about the same thickness and then I'm just going to add this one little piece of trim that caps that joint of the drywall in the wood together and paint it all in it's going to be absolutely seamless wow thank God I got somebody on the inside helping me out Matt just reminded me that I didn't spray foam this Gap yet and that's really key right no air leaks in the ceiling all right [Applause] uh -huh working with these cans upside down you sure lose a lot of the air but okay mission accomplished thank you
