It's really efficient. 85 00:04:02,966 --> 00:04:04,100 Kevin: Nice. Richard: And even though 86 00:04:04,166 --> 00:04:05,833 we're making the building slightly bigger, 87 00:04:05,900 --> 00:04:07,500 we're insulating and putting windows in 88 00:04:07,566 --> 00:04:08,866 so we don't need a larger size unit. 89 00:04:08,933 --> 00:04:10,266 Kevin: Perfect. Richard: So it does mean 90 00:04:10,333 --> 00:04:11,600 that we have a chance, though, to fix a few 91 00:04:11,666 --> 00:04:14,333 of the minor ductwork issues that might exist. 92 00:04:14,400 --> 00:04:15,400 Kevin: Okay. Richard: Alright. 93 00:04:15,466 --> 00:04:16,800 One is right here in the primary. 94 00:04:16,866 --> 00:04:18,233 Kevin: Yeah.

It was a gravity system. 98 00:04:24,266 --> 00:04:27,066 It would have been coal fired. No fan, no electricity. 99 00:04:27,133 --> 00:04:29,166 So the ductwork run would have been as straight 100 00:04:29,233 --> 00:04:30,933 as it could from the basement. 101 00:04:31,000 --> 00:04:32,933 And then it came up, and it just filled this place. 102 00:04:33,000 --> 00:04:35,133 There was no air conditioning even dreamed of back then. 103 00:04:35,200 --> 00:04:38,566 But now as we're adding more load and we have a fan, 104 00:04:38,633 --> 00:04:42,166 now we have to think about when this thing comes on, 105 00:04:42,233 --> 00:04:44,700 now it could get actually pulled into the return 106 00:04:44,766 --> 00:04:47,466 and not go and fill this room. Kevin: So originally okay, 107 00:04:47,533 --> 00:04:49,000 but with a system under pressure, no good. 108 00:04:49,066 --> 00:04:50,366 Richard: That's right. 109 00:04:50,433 --> 00:04:52,233 So it invited us to think about relocating it. 110 00:04:52,300 --> 00:04:55,000 And we found some real estate on the lower floor 111 00:04:55,066 --> 00:04:58,066 so we could find a way to get a new supply right here... 112 00:04:58,133 --> 00:05:00,366 Kevin: Yeah? Richard: ...and then another one right here 113 00:05:00,433 --> 00:05:01,833 where we're going to come up here. 114 00:05:01,900 --> 00:05:04,300 So now you've got a much better air delivery system 115 00:05:04,366 --> 00:05:06,166 and abandon that one, okay? Kevin: Very nice. 116 00:05:06,233 --> 00:05:07,666 Richard: So too in the baby's room. 117 00:05:07,733 --> 00:05:09,700 We found a similar situation. 118 00:05:09,766 --> 00:05:11,333 You can see the original register right here 119 00:05:11,400 --> 00:05:12,800 where it really doesn't want to be, 120 00:05:12,866 --> 00:05:14,300 but perfect back in the old days. 121 00:05:14,366 --> 00:05:17,333 So we found a way to actually come up below us 122 00:05:17,400 --> 00:05:19,766 and in a joist bay right here, 123 00:05:19,833 --> 00:05:22,366 end up with a new supply register exactly 124 00:05:22,433 --> 00:05:24,133 where it wants to be -- against the outside wall 125 00:05:24,200 --> 00:05:25,633 where the heat loss is and near the window, 126 00:05:25,700 --> 00:05:27,200 just like in the primary. Kevin: Very nice. Okay. 127 00:05:27,266 --> 00:05:29,700 Richard: The HVAC subs are here, and they are underway. 128 00:05:32,366 --> 00:05:34,033 So here in the first floor, Kevin, you can look up 129 00:05:34,100 --> 00:05:35,766 and see where the duct used to run. 130 00:05:35,833 --> 00:05:37,166 And this thing came up here. 131 00:05:37,233 --> 00:05:38,400 It was covered in asbestos, 132 00:05:38,466 --> 00:05:40,166 so we knew we had to modify it anyways. 133 00:05:40,233 --> 00:05:42,100 And we also had all this chimney mass and that got changed. 134 00:05:42,166 --> 00:05:43,466 Kevin: Although, back in the day, 135 00:05:43,533 --> 00:05:45,166 that's a pretty good place 136 00:05:45,233 --> 00:05:46,733 to run ductwork for a gravity system, right? 137 00:05:46,800 --> 00:05:48,200 I mean, right next to the chimney. 138 00:05:48,266 --> 00:05:49,933 Richard: Shortest distance between two points. 139 00:05:50,000 --> 00:05:52,266 Kevin: Okay. Richard: So with all this new massing here, 140 00:05:52,333 --> 00:05:54,966 though, we found a way that we could hide the ductwork. 141 00:05:55,033 --> 00:05:57,700 Mike's underway right here running that new supply 142 00:05:57,766 --> 00:06:00,566 here in that corner up to the one side 143 00:06:00,633 --> 00:06:02,400 of that primary bedroom right there. 144 00:06:02,466 --> 00:06:04,433 Kevin: So from the basement. 145 00:06:04,500 --> 00:06:06,033 Kind of ironic that he's putting it next to our gas fireplace. 146 00:06:06,100 --> 00:06:07,900 So similar idea to... 147 00:06:08,000 --> 00:06:09,600 Richard: And then James is working here in the corner. 148 00:06:09,666 --> 00:06:11,066 Hey, James. James: Hey, Richard. How are you? 149 00:06:11,133 --> 00:06:12,800 Richard: So you're hiding it in the corner? 150 00:06:12,866 --> 00:06:15,233 James: Yeah, so Charlie's guys cut us a chase up in the bookcase 151 00:06:15,300 --> 00:06:16,966 to get the duct up to the second floor for us. 152 00:06:17,033 --> 00:06:19,400 Kevin: Okay. James: So we have three options of ducts here. 153 00:06:19,466 --> 00:06:21,833 We can go round, oval, or rectangular. 154 00:06:21,900 --> 00:06:24,466 Kevin: Rectangle. Obviously. It's going to fit better. 155 00:06:24,533 --> 00:06:27,433 James: Most people would choose the oval or the rectangular 156 00:06:27,500 --> 00:06:29,133 to save on space, 157 00:06:29,200 --> 00:06:31,266 but the correct is actually the round. 158 00:06:31,333 --> 00:06:33,300 This is going to give us the best airflow 159 00:06:33,366 --> 00:06:36,033 for the performance upstairs, heating and cooling, everything. 160 00:06:36,100 --> 00:06:40,333 The oval is actually about a 20% to 25% airflow restriction 161 00:06:40,400 --> 00:06:42,466 compared to the round. Kevin: No, no, no, no, no. 162 00:06:42,533 --> 00:06:45,600 If I squeeze this and make it an oval, they're the same pipe. 163 00:06:45,666 --> 00:06:48,133 Richard: If I squeeze a hose, a garden hose, 164 00:06:48,200 --> 00:06:50,566 I'm not really changing the inside diameter, 165 00:06:50,633 --> 00:06:53,800 but I am providing some restriction and more friction. 166 00:06:53,866 --> 00:06:55,400 And that's exactly what happens here. 167 00:06:55,466 --> 00:06:57,266 Kevin: So shape matters? James: Exactly. Yep. 168 00:06:57,333 --> 00:06:59,566 Kevin: I would just figure it was like a volume thing. 169 00:06:59,633 --> 00:07:01,200 James: And then this rectangular wall stack, 170 00:07:01,266 --> 00:07:04,600 this is about a 40% less airflow. 171 00:07:04,666 --> 00:07:06,633 Richard: So there's a chance you might need two of these 172 00:07:06,700 --> 00:07:08,433 to get the equivalent of this. 173 00:07:08,500 --> 00:07:09,833 Kevin: When I look at those two next to each other, 174 00:07:09,900 --> 00:07:11,433 it's inconceivable to think 175 00:07:11,500 --> 00:07:13,100 that that delivers less air than this. 176 00:07:13,166 --> 00:07:14,200 Richard: That's right. Kevin: Oh, my gosh. 177 00:07:14,266 --> 00:07:15,566 Richard: It's about the friction. 178 00:07:15,633 --> 00:07:16,800 And they'll hide that.

James: Thank you. 180 00:07:18,333 --> 00:07:19,766 Richard: And over here is where they'll lose the ductwork 181 00:07:19,833 --> 00:07:21,066 for the baby's room right here. 182 00:07:21,133 --> 00:07:22,966 Again in the corner of the bookcase, 183 00:07:23,033 --> 00:07:24,433 there's the vertical. 184 00:07:24,500 --> 00:07:26,066 If you look, here's those joist bays. 185 00:07:26,133 --> 00:07:27,500 They'll be able to run that horizontal 186 00:07:27,566 --> 00:07:28,633 all the way to that corner. 187 00:07:28,700 --> 00:07:30,000 Kevin: And then Charlie buttons it up, 188 00:07:30,066 --> 00:07:31,833 and you hardly know it's there, 189 00:07:31,900 --> 00:07:33,500 and it's a good compromise to get good airflow. 190 00:07:33,566 --> 00:07:34,733 Richard: That's right. 191 00:07:34,800 --> 00:07:35,800 And they'll be done with all this rough-in today. 192 00:07:35,866 --> 00:07:36,866 Kevin: Nice. 193 00:07:36,933 --> 00:07:45,633 ♪♪ 194 00:07:45,700 --> 00:07:54,466 ♪♪ 195 00:07:54,533 --> 00:08:03,233 ♪♪ 196 00:08:03,300 --> 00:08:04,800 Hey, Charlie. 197 00:08:04,866 --> 00:08:06,266 Charlie: Hey, Kevin. Kevin: So it's HVAC day. 198 00:08:06,333 --> 00:08:07,566 We're working with Richard and James. 199 00:08:07,633 --> 00:08:09,266 We're doing duct work downstairs. 200 00:08:09,333 --> 00:08:10,866 They've got an air handler in the basement, 201 00:08:10,933 --> 00:08:12,900 and I'm told another one is up here. Charlie: Actually, 202 00:08:12,966 --> 00:08:15,300 you walked right under the scuttle hole to get up there. 203 00:08:15,366 --> 00:08:19,200 Kevin: Oh, boy. I see an uninsulated roof. 204 00:08:19,266 --> 00:08:21,300 Charlie: HVAC system lives up there. 205 00:08:21,366 --> 00:08:24,200 2x6 rough framing, no insulation. 206 00:08:24,266 --> 00:08:27,400 Kevin: So that thing must be working like crazy. 207 00:08:27,466 --> 00:08:29,433 It gets so hot up there in an attic. 208 00:08:29,500 --> 00:08:31,233 Charlie: Richard went up there with a thermometer, 209 00:08:31,300 --> 00:08:33,033 and it was 120 degrees and climbing. 210 00:08:33,100 --> 00:08:34,733 Kevin: Insane. 211 00:08:34,800 --> 00:08:36,433 Charlie: But remember, wintertime, in the reverse. 212 00:08:36,500 --> 00:08:37,633 It's freezing up there. Kevin: Yeah. 213 00:08:37,700 --> 00:08:39,366 Charlie: So that's working overtime... 214 00:08:39,433 --> 00:08:41,366 Kevin: All year. Charlie: ...all year. 215 00:08:41,433 --> 00:08:44,400 Kevin: So at some point, they turned us into finished space. 216 00:08:44,466 --> 00:08:45,800 This is why we got all the walls up. 217 00:08:45,866 --> 00:08:48,700 But they also added HVAC... Charlie: That's right. 218 00:08:48,766 --> 00:08:49,766 Kevin: ...and didn't put insulation up there? 219 00:08:49,833 --> 00:08:51,500 Charlie: I know. It's crazy, right? 220 00:08:51,566 --> 00:08:53,800 But, I mean, they insulated above the ceiling... Kevin: Right. 221 00:08:53,866 --> 00:08:56,133 Charlie: ...and they continued it right down this roof line here. 222 00:08:56,200 --> 00:08:58,366 Kevin: Okay. So you're obviously going to fix that for us. 223 00:08:58,433 --> 00:08:59,866 Charlie: We are. Kevin: So what are you thinking? 224 00:08:59,933 --> 00:09:01,766 Charlie: So we have a few different samples right here. 225 00:09:01,833 --> 00:09:04,966 So this is a open-cell spray foam, right? 226 00:09:05,033 --> 00:09:06,833 Kevin: So you spray it in, it expands, 227 00:09:06,900 --> 00:09:08,600 and you get what from it? 228 00:09:08,666 --> 00:09:12,100 Charlie: So this is about 3, 3.5 per inch for an R-value, 229 00:09:12,166 --> 00:09:14,000 but vapor does travel through it. 230 00:09:14,066 --> 00:09:15,266 Kevin: Hence the name open-cell. 231 00:09:15,333 --> 00:09:16,500 Charlie: That's right. Kevin: Yeah. 232 00:09:16,566 --> 00:09:17,500 Charlie: So we have a closed-cell foam, 233 00:09:17,566 --> 00:09:18,666 about double the R-value, 234 00:09:18,733 --> 00:09:20,600 so it's at least a seven per inch... 235 00:09:20,666 --> 00:09:21,933 Kevin: Yeah. Charlie: ...and the vapor 236 00:09:22,000 --> 00:09:24,300 does not travel through it. Kevin: Okay. Yeah. 237 00:09:24,366 --> 00:09:26,433 Charlie: And there's a dense-pack cellulose here 238 00:09:26,500 --> 00:09:29,900 which is about three R-value per inch. 239 00:09:29,966 --> 00:09:31,733 Fiberglass is about the same, 240 00:09:31,800 --> 00:09:34,366 and that's what we have here above us in the ceiling. 241 00:09:34,433 --> 00:09:37,400 Kevin: Okay. So that's what we've got in the ceiling. 242 00:09:37,466 --> 00:09:39,433 Nothing on the underside of the roof. 243 00:09:39,500 --> 00:09:43,500 What do you want to do to get your R-value and insulate that? 244 00:09:43,566 --> 00:09:47,200 Charlie: Well, because we have the 5.5-inch old rafters... 245 00:09:47,266 --> 00:09:48,733 Kevin: Which isn't much. Charlie: ...which isn't much, 246 00:09:48,800 --> 00:09:52,366 and we have to contend with our energy code, our HERS rating, 247 00:09:52,433 --> 00:09:55,100 so we also have to meet that standard. 248 00:09:55,166 --> 00:09:57,666 So I want to use a closed-cell foam starting 249 00:09:57,733 --> 00:09:59,833 putting a continuous head of insulation 250 00:09:59,900 --> 00:10:02,566 right over the entire HVAC system. 251 00:10:02,633 --> 00:10:05,133 But I don't want to just spray down closed-cell foam 252 00:10:05,200 --> 00:10:07,533 to any fiberglass that was in this ceiling. 253 00:10:07,600 --> 00:10:10,033 Kevin: So this is what came out right here, 254 00:10:10,100 --> 00:10:12,866 which is actually pretty deep. 255 00:10:12,933 --> 00:10:14,933 So how's that -- Oh, yeah. Charlie: Yeah. 256 00:10:15,000 --> 00:10:17,500 So whenever they renovated and did work here, 257 00:10:17,566 --> 00:10:19,400 they put 2x10s, which was great, 258 00:10:19,466 --> 00:10:21,233 and they put the 10 inches of insulation in here. 259 00:10:21,300 --> 00:10:22,966 Kevin: Were you surprised to see that? 260 00:10:23,033 --> 00:10:24,933 Charlie: I was surprised because when I was up 261 00:10:25,000 --> 00:10:27,800 in the attic looking down, I couldn't see any sign of this. 262 00:10:27,866 --> 00:10:29,233 So, I mean, they did the right thing. 263 00:10:29,300 --> 00:10:30,933 They threw it down 2x10. 264 00:10:31,000 --> 00:10:33,500 They got extra insulation in here... Kevin: Yeah. 265 00:10:33,566 --> 00:10:35,866 Charlie: ...but once again, they failed up top right. Kevin: Right. 266 00:10:35,933 --> 00:10:38,433 Charlie: That system is run-- you know, really working overtime. 267 00:10:38,500 --> 00:10:40,933 I said, "We're gonna insulate that properly. 268 00:10:41,000 --> 00:10:42,200 Let's just put a slice through here. 269 00:10:42,266 --> 00:10:43,733 It's one big patch. 270 00:10:43,800 --> 00:10:45,333 We're gonna patch it in once we're done." 271 00:10:45,400 --> 00:10:48,833 But I pulled the fiberglass out. Now then they spray foam. 272 00:10:48,900 --> 00:10:51,000 They can reach up, spray right down through here, 273 00:10:51,066 --> 00:10:52,600 spray right down here. 274 00:10:52,666 --> 00:10:54,266 And then this is a knee wall that we have, 275 00:10:54,333 --> 00:10:55,766 but we have access on the other side. 276 00:10:55,833 --> 00:10:57,200 We'll get in behind there, 277 00:10:57,266 --> 00:10:59,066 pull any of the fiberglass out 278 00:10:59,133 --> 00:11:01,366 and we'll continue that closed-cell foam right down, 279 00:11:01,433 --> 00:11:03,400 giving us our insulated hat. 280 00:11:03,466 --> 00:11:06,166 Kevin: So you get a continuous vapor barrier. 281 00:11:06,233 --> 00:11:10,133 You get more R per inch. We like all of that. 282 00:11:10,200 --> 00:11:12,766 This is gonna help you meet your total score 283 00:11:12,833 --> 00:11:14,933 for that energy rating. Charlie: It's going to help us. 284 00:11:15,000 --> 00:11:17,100 I bet you it puts us over, which is great. 285 00:11:17,166 --> 00:11:19,066 Kevin: Love it. Let me just challenge you here. 286 00:11:19,133 --> 00:11:21,500 Some people, they just don't like foam. 287 00:11:21,566 --> 00:11:23,000 Charlie: Correct. Kevin: For whatever reason, 288 00:11:23,066 --> 00:11:25,566 they're just like, "I don't want foam in the house," which I get. 289 00:11:25,633 --> 00:11:28,633 Could you get this solved with the alternatives? 290 00:11:28,700 --> 00:11:31,266 Charlie: I could solve it with any of the insulations. 291 00:11:31,333 --> 00:11:33,366 It would definitely be more work to do. 292 00:11:33,433 --> 00:11:36,233 But remember, this is not a gut renovation or, of course, 293 00:11:36,300 --> 00:11:39,300 a new house where it makes it easier to insulate 294 00:11:39,366 --> 00:11:40,866 with other insulations. Kevin: Right. 295 00:11:40,933 --> 00:11:42,666 Charlie: In this case, I have to make sure 296 00:11:42,733 --> 00:11:46,233 I hit every nook and cranny with a vapor barrier protection, 297 00:11:46,300 --> 00:11:48,166 and I couldn't sit there and promise you that. 298 00:11:48,233 --> 00:11:50,400 Kevin: Right. And if we didn't use this 299 00:11:50,466 --> 00:11:52,066 with that really high R rating, 300 00:11:52,133 --> 00:11:54,566 you've got to hit that number for the energy code. 301 00:11:54,633 --> 00:11:56,600 Charlie: That's right. Kevin: If you don't hit it here, 302 00:11:56,666 --> 00:11:58,300 or I should say if you don't maximize your insulation here, 303 00:11:58,366 --> 00:12:00,633 what happens to that number? Charlie: Well, a lot of times, 304 00:12:00,700 --> 00:12:03,300 let's say I could only do half for whatever the reason is, 305 00:12:03,366 --> 00:12:05,300 I might have to overcompensate somewhere else. 306 00:12:05,366 --> 00:12:08,133 Might be they might say, "I want you to change your HVAC system. 307 00:12:08,200 --> 00:12:09,966 That's not quite efficient enough for us, 308 00:12:10,033 --> 00:12:12,233 so we're going to force you to change that." 309 00:12:12,300 --> 00:12:15,100 Well, if I insulate, that's not going to work as hard. 310 00:12:15,166 --> 00:12:18,400 So dollar-wise, it's cheaper. Kevin: So that's the solution. 311 00:12:18,466 --> 00:12:19,866 Alright. Sounds good. 312 00:12:19,933 --> 00:12:21,666 And, hey, listen, don't sell yourself short. 313 00:12:21,733 --> 00:12:24,200 You've been overcompensating the entire time I've known you. 314 00:12:24,266 --> 00:12:25,333 Charlie: Alright. It's fair to say. 315 00:12:25,400 --> 00:12:26,333 Kevin: [ Chuckles ] 316 00:12:26,400 --> 00:12:34,100 ♪♪ 317 00:12:34,166 --> 00:12:41,866 ♪♪ 318 00:12:41,933 --> 00:12:49,633 ♪♪ 319 00:12:49,700 --> 00:12:57,400 ♪♪ 320 00:12:57,466 --> 00:13:00,833 Well, the rain has started, but that's not a problem, Tommy, 321 00:13:00,900 --> 00:13:03,400 because we're starting to install our new windows 322 00:13:03,466 --> 00:13:05,166 so we can get the house weather-tight. 323 00:13:05,233 --> 00:13:07,766 Tom: Right. Kevin: Uh, process? Product? 324 00:13:07,833 --> 00:13:09,366 What are we putting in? Tom: Well, we're installing 325 00:13:09,433 --> 00:13:11,566 this new energy-efficient window. 326 00:13:11,633 --> 00:13:14,333 Those are 15 lites over 1 lite, 327 00:13:14,400 --> 00:13:16,300 and it's simulated divided lite, 328 00:13:16,366 --> 00:13:19,166 which means the divider between each one of these muntins 329 00:13:19,233 --> 00:13:20,933 on the inside and outside. 330 00:13:21,033 --> 00:13:22,666 So when you look diagonally at the window, 331 00:13:22,733 --> 00:13:24,033 you can't see through the muntins. 332 00:13:24,100 --> 00:13:25,466 Kevin: Okay. 333 00:13:25,533 --> 00:13:26,900 Going into an existing opening 334 00:13:26,966 --> 00:13:28,700 where we took out the old windows. 335 00:13:28,766 --> 00:13:31,400 Tom: Right. Now, under the porch here, 336 00:13:31,466 --> 00:13:33,800 this doesn't really need to be flashed like 337 00:13:33,866 --> 00:13:35,466 we would do normally, 338 00:13:35,533 --> 00:13:37,200 but it's good practice to always do them right. 339 00:13:37,266 --> 00:13:40,133 Now, the siding on the porch is stained. 340 00:13:40,200 --> 00:13:42,633 The rest of the new house has got new siding, 341 00:13:42,700 --> 00:13:47,166 so now we have to think about how we flash the window casing 342 00:13:47,233 --> 00:13:49,033 when it meets the siding here. 343 00:13:49,100 --> 00:13:50,933 And this wasn't flashed at all. 344 00:13:51,000 --> 00:13:53,433 I can see that there's a house wrap in there. 345 00:13:53,500 --> 00:13:57,400 There's no way that you can stop water from wind-driven rain 346 00:13:57,466 --> 00:14:00,666 to get in there when this board expands and contracts this way. 347 00:14:00,733 --> 00:14:02,800 If this joint opens up just the hair 348 00:14:02,866 --> 00:14:04,733 or if the rain's really driving, 349 00:14:04,800 --> 00:14:06,433 the water will go in there, run down. 350 00:14:06,500 --> 00:14:08,466 It'll actually rot the wall right here. 351 00:14:08,533 --> 00:14:12,300 I've seen it many times. Rotting wall, rotting sill. 352 00:14:12,366 --> 00:14:13,900 They blame it on the window. 353 00:14:13,966 --> 00:14:15,766 It should be blamed on the flashing. 354 00:14:15,833 --> 00:14:18,800 Kevin: So we got to get a good backer behind casing 355 00:14:18,866 --> 00:14:20,600 and the siding right there?
