How to Insulate Walls and Ceilings — by Home Repair Tutor

Okay, it s starting to get cold in Pittsburgh And today I m going to put off raking all these leaves because I m going to have my buddy Bill insulate his walls and his ceilings over his new addition at his home. So we re going to show you how to do that and save a ton of money by insulating your home, And we ve got some really great tips for you Plus an awesome surprise at the end. So let s get started. Okay, these are all the supplies. I need for installing insulation, respirator eyewear. You got a razor measuring tape, something to cut insulation with gloves, and then I just pack a chisel. So I can push the insulation into certain places that are hard to reach. Okay. Now it s time to go to Bill s. Okay, so we re over at Bill s house, We re going to be putting in an insulation, Why? Why are we putting in an insulation Because we need an addition on our house? Why do we need an addition on our house? We don t have enough bedrooms. We got one baby, two babies and a third baby, So we ran out of bedrooms in the house, So we had to build another bedroom. So we have our little helpers here, but Bill and I are going to be putting in an insulation. So we re going to show you how to do that. Right now Say bye, Bye For Bill s addition, we ve actually got 2 x 6 framing. We re using the R 21 Kraft Faced Batts because it fits perfectly into the 2 x 6 framing. This is actually 5 thick x, 15 wide x, 93 long Now the Kraft Faced which has paper on it like this is a vapor retarder. What this does is prevent mold and mildew from getting inside the stud bay. The reason why we re using an R 21 is when you re, building an addition on your house. R 21 is the minimum R value that you need for the current Energy Code standards. The nice thing about Johns Manville products is that they re formaldehyde free And, if you ve got kids or you want to actually keep yourself safe, formaldehyde free is the way to go. So why do you want to insulate your house? It s pretty much. A no brainer right, You got to keep it warm It s. What were you saying It? S got thermal and sound control, Which is great for when you have kids Yeah Right Or if you live in a busy area. Let s say you live in the city and you want to try to cut down on noise pollution. Adding insulation to the walls is perfect. For that. The other thing to keep in mind is this: you just put in a new HVAC system right so by putting an insulation, you cut down on the stress of constantly running your heating or cooling system, So it really helps out in that way too. So how do you pick out the insulation that you want? So in this case we have 2×6 s and they are 16 on center. So you want to pick out the insulation that fits into the stud bay Because they have different stud bay widths that you can work with Different house builders will build in different ways. Most houses are going to be 16 on center, so most of your stud cavity bays are going to be 14 wide. Now there are other framing methods where you can go up to 24 wide, In which case you would want something that s 22 wide batts. So for the ceiling we re actually using R 38 And Bill s. Ceilings here are what are these joist sizes? These are framed 24 on center, So we got a 22 wide batt for the ceilings. I m measuring the inside of my wall bay to determine the height for the insulation that we need to have here. One thing that we messed up is that I ordered insulation that s slightly too tall. All you need to do is just take a framing square. Such as this Press down real hard till you get a nice spot to cut with A standard utility knife is all you need to cut this And take a few passes at it. Just to make sure you get all the way through to the insulation. There s a couple of different tools that you can use to cut this A utility knife is probably one of the most common ways. This is an actual insulation knife designed for cutting insulation. It works very well for that. We have electrical wiring that s going through some of these stud bays And it s recommended that you fill every hole where you have penetrations, for where your wires is. We just got a little bit of caulking here And we re just going to fill each one of these holes before we get insulating. So what we want to do is get this right up to the top. You don t want to smash it in there. You just want it to fit very nicely. I m just going to tuck this in all the way down And if you notice there s an electrical line here, There are two different ways to handle electrical line. They say the preferred method is to split the batt down center. Take half of it, tuck it behind the wire. So you get a nice layer of insulation behind that wire, so you get nice pure insulation, all the way from floor to ceiling. Most importantly, you just want this to fit exactly right. You don t want to smash it down in You. Don t want it to be tucked And you don t want it to be stretched. You want it to go in as comfortable as it can. The outlet box, whenever we stuff the insulation here, you don t, want to just jam the insulation in around it because, like I said before, if the insulation is smashed, it s not going to work as good. You want this stuff to be puffy and fluffy. Just the way that it s designed to be installed At this point, this is where my insulation knife will come in handy. We re going to go right to the top edge of the box here and just cut the insulation in a square shape same size as the electrical box Remove this little square here I left a little bit here That should be enough to fit behind the box. I tuck this in behind the box And when we re done it should have a nice even fit around that box All right. So while Bill is finishing off the insulation, I wanted to tell you that Johns Manville just sponsored this video, and this is part of their Winter Warrior program, And we really want to encourage you to when you insulate your house. If you re using a Johns Manville insulation share that on social media and use winterwarrior That way, you can inspire other people to make their homes more comfortable this winter. You can also find the products that we re using in this video at Lowe s and Home Depot, And if you don t have one of those stores in your area, you can go to Johns Manville website and find a store locator in your area. Now that I got the insulation stuffed in the wall, I ran my hand along it Make sure it s nice and smooth in place. You ll notice that it has these little tabs on here. Now there s a couple of ways to install this insulation There s. What s called a friction fit insulation, which this is not that type of insulation. This one is meant to be stapled, So you could either surface staple to the face of the stud or you could staple to the inside of the stud. Now your drywallers will appreciate it if you staple to the inside of the stud, Because when you staple to the outside, if your staple doesn t sink all the way, it can cause a lump in the drywall, and you don t want that. So Johns Manville suggests for their product is that you staple every 6 to 8 along the inside of the stud. Now when you staple this, you ll be pushing the insulation back, but they will just puff back up and come back to the right dimension. All right! We have a little bit of a space here between this stud and that one, So we need to actually cut down some of the insulation for the space Bill. S doing the exact same thing, with these tiny little piece of insulation that is above the head or for the window, You got to cut them to size, make sure that they re tight and flush with all of the framing. Otherwise, your insulation is not going to do its job Where you have windows, you definitely want to use expanding foam around the window frame to cut down on any draft coming into the house. So for the ceiling we re going to be using the R 38 13 thick x, 24 wide x 48 long pieces. Well, I m about to install the Johns Manville ceiling insulation R 38. As he said it s 13 thick, And I was wondering How am I going to get a 13 thick 24 wide batt in the ceiling? Well, they make them in 48 sections to make it easier to install this in the ceiling. I was very glad to see that Okay, well, we got one bay of the ceiling filled in with all the insulation. Now I have all these seams here, where they re separated. This just needs to be taped together with a polytape or a tape that is designed for taping insulation. It s also to make sure that the vapor barrier is continuous throughout the entire ceiling plane Also done in the walls as well. The walls you really shouldn t have any seams that need tape. But if you have any tears or anything like that in you moisture resistant layer, then that s where you re going to want to install polytape just to seal all that up and make sure it s air tight, All right, so that s how you insulate your Walls and your ceilings, We hope that you like this video and got some great tips Now here s the surprise, We re going to be giving away a 100 gift certificate to one of our fans.
