Insulation, Drywall, Bathroom Waterproofing - Real Rebuild Ep. 5
HTML-код
- Опубликовано: 8 дек 2023
- Matt walks through the entire insulation process and why he chose to use Rockwool insulation on his personal home as well as a retesting of his famous sound test but with drywall installed. Then he talks about getting ready to hang drywall by going over his blocking strategy in his kitchen, stairs and bathrooms. He then ends the episode by examining his strategy to prevent and control interior flooding should the worst happen.

Matt….i have a house with no insulation….my kids still don’t hear me when I call upstairs for dinner 😅😂
I've watched them all Matt, I really enjoyed watching you build a well thought through house...
Thanks for the walkthru of your house and the benefits of using Rockwool
Awesome video contents Matt! Loved all of it. Great building execution👌
Thank you for sharing, took a lot of notes
When I added rockwool to my 2nd story addition I built, it was so quiet that I had to have a fan going to keep me from going insane. That stuff absorbs all the sound.
At my box stores rock wool is more than double the price of other insulation. Where are people finding it “close” to the same price?
My builder quoted me the same (double the price of fiberglass) here in Dallas, TX
Lowes was the cheapest I found
@@jacobecorder in the upper Midwest Menards has a different brand of mineral wool that was a little closer to fiberglass prices but still higher
@@sheepdogonthehill yes. That stuff is stupid overpriced. I'm in Minnesota and I get mine from Lowe's. It's about 1$ per sqft for r15. And price is consistent to r30 so 2$ per sq ft for r30. I did 19.2 oc so I had lots of cutting. They don't make it for 19.2 spacing.
The name brand of Rockwool is like $85 for 12 batts. But the other brands of mineral wool are a little more reasonable, at $29 for 7 batts.
Just for the record there's no such thing as "totally soundproof". At least not on a home building budget.
Also the Rockwool contributes relatively little to the sound transmission loss of the walls and floors compared to the drywall. Since it's no longer exposed to the air it is no longer providing sound absorption. Its role now is to dampen resonances within the wall cavity.
Drywall, as you mentioned, is highly acoustically reflective.
I'd you want to deaden the acoustics you need to put up some absorptive panels. Rockwool Comfortboard 80 and 100 are excellent for acoustic panels.
Nice!
You have integrated decibel meter (going also below 40 dB) on that Apple Watch Ultra ;)
What are effective ways of air sealing existing electrical and low volt boxes, especially on exterior walls? These boxes seem to throw huge differences on thermal.
Its been a good journey
Great video Matt and information thank you one suggestion my wife and I are always yelling at our kids for dinner or for other things so we ended up buying Amazon Alexa and place them in all the bedrooms and now no more yelling she can announce dinner time or come downstairs or are you doing your homework? Anything pretty coolthanks again Matt
Matt don't you think a grab rail at the toilet would be better at a 45 degree angle for ergonomics? Love your videos
Matt, with a 30yr old house with blown in insulation, would it be more cost effective to remove and replace or, condition the attic space to reduce the temperature swings experienced seasonally?
If you're gonna go the conditioned route with spray foam the blown in must be removed. Especially if it's fiberglass. The atomized particles of the foam in the fiberglass will cause an odor. The blown in would also trap moisture now that the attic is part of the conditioned space. Do you have HVAC in the attic? If so, conditioned attic. If not vacuum out the old, air seal EVERYTHING then blow in R60 cellulose
Why not use foam?
Rockwool does have formaldehyde fyi
It’s minimal from the data sheet they provide…
We are hoping to start a new build in about a year and all I have to say is, Screw You! You are going to cost me so much more money. I mean, I had ideas about things I wanted. Now I’m not going to be sure where to draw the line. It will be our last house so blocking for grab bars is cheap and something I might have missed. The rock wool and Q/R is going to be one of many adds. I am loving having found your channel and my future builder is probably going to hate you as well.
Why cant we find Rockwool at the Big Box orange and blue stores anymore???? Rockwool ...... hello ? Any ideas lol
lowes carries it. battt sizes for 2x4 and 2x6 16" o/c wood framing is carried in store near me. rest available for order at lowes online. HD doesn't carry it
Call an insulation supplier if its a decent amount, plus you'll get a better deal.
September 2022 nowhere to be found NW Houston.
They are probably in the pockets of the pink panther so they sell his shit.
Purchase some Google Home minis for your kitchen and everyone of their spaces upstairs. Then you can broadcast suppers ready message from downstairs to all these little speakers.
What if you did no blocking and just guessed at the end? Asking for a friend.
Rockwool looks like a great product but disappointed that you don’t mention the formaldehyde issue, which can have big impact on indoor air quality. Of course you wouldn’t install something if you thought it would hurt oyur family so it may be a non issues but you don’t know until you know and that could be a costly choice, both in terms of health and remediation costs. Great show -I watch them all- but disappointed that you don’t go deeper on this important issues.
It’s minimal according to the datasheet they provide
Yes, I saw that. Of course they’re gonna downplay it. How much poison is acceptable in your air?
I don't understand why we're doing Matt's home build again. Did we not see all this already?
why don't we just build homes out of one thing?... concerete.....
CO2 emissions. Wood is also easier to work with.
@@phamlam3720
think thermal mass and the fact concrete accounts for like 9% of total gas exchange while depletion of our forests account for all the rest....
@@jonerlandson1956 You are going to spend a bit of money heating that thermal mass anywhere in climate zone 4 or greater.
Most lumber you see come from sustainable forest. They are cut down and regrown. We aren’t using old growth.
@@phamlam3720
i disagree... i think it ideal... thermos bottle construction... and absorbent refrigeration systems...
@@phamlam3720
concrete inside and out separated by mineral wool spirits...
