Hey Andy thanks for the comment and sounds like a great results for your hard work. I am also in the process of doing a insulation 2.0 on my 2000 built home and would love to hear any tips/tricks or suggestions you can offer from your experience. I do have interest in doing attic ceiling spray foam but I have a gas furnace in my attic in Texas so from the video it appears I cannot do the spray foam in the attic ceiling! I am not sure if there is a work around or hack that could help and still allow to use spray foam. I was also confused alot of people commented on several videos not to use spray foam and that it wad dangerous trading the moisture in the attic or causing the wood to rott causing mold! Any thoughts of that?

I’ve been watching videos like this for years and have a buddy who spray foamed his home and swears by it; any reason (other than $16k in additional cost) to NOT spray foam the attic space instead?

I did this in my house in Virginia before the builder put the insulation in. Since I was working in the summer, I would go by the house at around 9pm when the sun went down and worked till 11pm or midnight spraying the foam along the top plate and pipe/cable penetrations as well as electrical boxes in the ceiling. I also had a box fan (to cool me off when working in that still-hot attic) running off an inverter and a 12V battery I kept charged with solar panels since the electric company was taking their time getting the electricity connected. (This 12V battery also powered the backup sump pump to keep the basement dry, and continues to serve as a backup if the power goes out). I asked the builder about sealing the top plates but they said they don't do that. Fine, I'll do it myself. Results? My heatpump can maintain 68F in the house when it's 17F out, without using any aux heat. In fact I have the aux heat on a switch that I can turn on if I determine that the house is getting too cold. Never needed to turn it on yet.

I know your target audience is mostly home builders, but I'd love to see more on this line of what homeowners can do for an existing house - what we should look for, who we should be talking to, what products to ask about, etc. This video specifically would have been hugely valuable to me a couple years ago when I re-insulated. While I had gained enough knowledge form your channel and did ask them to "air seal", it was not done anything remotely like what you shown here. Probably because I used a typical insulation company. Even with with new R49 (code was R39) and radiant barrier install, the house is still very poor performance thermally. When it gets hot here (San Francisco Bay Area), my AC can run for 10 hours straight and the house will still get WARMER during peak heat.

One thing that helped my (110 year old) Pennsylvania house this summer was putting radiant barrier up in the roof stringers, done "the Texas way" (as in this video), but with two layers of barrier. This was good for a 15--20 degree F drop in attic temps on sunny days, and didn't take very long to put in. And it has really improved the cooling in my upper floors on sunny days. (Tip: get the airflow right: guide air into the barrier chambers in at/from the eaves; leave a decent gap at the ridge if you don't have a ridge vent.)

I have a 1960 house so at least half of the batts needed to be cut once to 3 times . Please use gloves long sleeves and eyewear. I rented a vacuum to remove old insulation for about 400 bucks and 2 days . The rockwool cost me about 3k for a 1400 square foot house and about 400 square feet for the garage . Not sure if I'll use rockwool r23 again or r30 batts for the second layer .the foam gun was about 50 bucks and you'll need at least 3 cans of foam for the same square footage . I won't see the full benefits till I finish this winter so next summer should be great for me .

No door to seal or insulate is brilliant.

I've now consumed I don't know how many hours of attic insulation thanks to Matt and other videos similar. I apologize ahead of time for the length of this comment but i'd love some advice from @Matt Risinger or someone else with knowledge in this space... House info: I live in GA, and my attic is almost identical to what they showed on this. HVAC (furnace) up in the attic with the same type of vent, blow in insulation, etc. My furnace is ~ 20 years old and will need to be replaced eventually. I got a quote from a well respected company in my area and they were pushing me really hard on another 80% efficient unit even though I asked for a more efficient so that I could essentially do what Matt showed in the Insulation 2.0 video where you bring the attic into the conditioned space. No matter how many different ways I asked, the answer was "you don't need anything more efficient than 80% in GA". More or less what that company was recommending was what was shown in this video - almost exactly. So my questions are here... Is it worth going the extra mile to make the attic space conditioned as opposed to what they did here and just sealed off the spaces coming down from the attic and reinsulating? And when I say "worth it" - is it worth the upgrade from an 80% efficient furnace to a 90%+ (most seem to be 96% once you go past 80), insulate the roof deck with something like rockwool that Matt shared in another insulation video, and seal off the air gaps on the attic floor? Or...would it make more sense to just do what they did here? I plan to be in my house for probably another 10 years, and I really like to be comfortable. I've done tons of reading on all this and watching videos like this to educate myself. I have ridge vents on the roof, so my understanding is I'd have to put in baffles that basically run from the soffits up to the ridge vents. I'd then want to put ~8" rockwool insulation underneath those baffles. I'd need to suck out the insulation in the attic and then seal all the leaks. I'd need to replace the furnace with a more efficient version that could be pvc vented. Thoughts? Ohh...and the reason I am considering rockwool over something like the open/closed cell foam is I've seen some videos where these things have gone horribly wrong - like making people sick, the home is unlivable, etc. And once you spray the foam...there's really no backing out afterwards.

It would be more helpful to show realistic conditions and how to deal with them than these ideal situations. In a 4/12 it isn't about what you use as much as it is in how to lay down correctly and how to reach the eaves for effective coverage. Not much value to showing an attic with eight foot peak and scads of room to move about in.

Howdy Matt, My name is Wayne Lanham. I love watching your videos! My wife Cindy and I live at Lake Brownwood. We have an amazing home built in the early 1980's by a banker from Lubbock. He was building a bit ahead of the current building trends. One thing he did not do well was the insulation of the home. We are all electric and our electric bill averages $750+ per month year-round. We need some help making the right decisions on how to proceed with fixing our home. We are both real estate agents with Lake Homes Realty and I'm also in the Scrap Metals business. We would love to hear from you and get some ideas. Wayne & Cindy

Would it have been an option to blow all that insulation to one side, seal the bare ceiling and then blow it back and do the other side?
@dalesaudio2 жыл бұрын
The recessed can light covers stick up so they don’t look like they have any R value at all. Wouldn’t it be better to remove the can light fixtures and replace them with the new flat LED style ‘can lights’? That way you could get an almost uniform R-49 across all of the ceiling. Also, any one you recommend for home performance work in Dallas? PS: Love the show!
@danielbuckner21672 жыл бұрын
Matt I wish you guys would have talked about some of the performance spray caulk used instead of canned foam it can be applied quicker and probably cheaper and doesnt need the insulation value of spray foam as the blown in goes right on over it. I know there is a big gap challenge that foam fixes but what about a combination of the two?

Spray foam the top of the exterior walls. The company I had come out did a great job with all the mechanical penetrations like light fixtures and vent fans. But they did not do the top of the exterior walls. So there is still an air path from the receptacles through the wall and through the gap between the drywall and top plate in the attic. So make sure to verify the top of the exterior walls.

Same attic with same leaks and a ridge vent with baffles and vented soffit. Was thinking of adding like 2 inches of foam without sealing ridge or soffits...leaving my Rockwool and white stuff on the ceiling. Good idea or recommend sealing up,pulling loose fill...then foaming? Livingston texas in the humid Houston market.

I suspect that many houses with rooms over garages have the floor truss area between the floor and ceiling completely open to the attic space in the front of the garage. It's made worse when they use open web trusses, now that air is leaking throughout the entire 1st/2nd floor space. My dad's house was built this way and it was very expensive to heat and cool. And it was built in 1987 when you'd think they know better, but this is Virginia.

non contractor question: Matt, could they have used before the insulation went in, that system that sprays some kind of plastic type stuff in the air to close out all the little leaks in the attic? I know they use it in new construction a lot & with the insulation gone, it was a lot like a new build. Thanks.

You have HVAC equipment in the attic that may need servicing. With R-49 insulation, the insulation will cover the bottom chord of the truss. What do you install to help a repair man safely reach the HVAC equipment and be able to work on it?

spray foaming the underside of roof sheathing is a big mistake because it can hide roof leaks. we bought a house in FL that had some past roof leaks and some of the sheathing was completely rotten and had to be cut out. the home inspection might have missed it if all that rotten plywood had been hidden by spray foam.

I have a problem with using blown cellulose fibers for insulation. Overtime, it attracts huge amount of dust and dirt particles which can be harmful to your lungs especially if a person has respiratory ailments like asthma. Anyone with an older "loosely" built home with blown insulation will attest just how dusty their home gets. We found out the hard way. My son has asthma. We bought a 70s ranch with blown insulation in the walls and attic space. But the HVAC was inadequate so I had a new system installed including new ductwork. Soon after, my sons asthma worsened to the point of having to be hospitalized. We changed the filters weekly to no avail. The dust was everywhere. It was a nightmare. My son had to stay with my parents until I could sell the house and buy another one.

Sorry i didnt read all the comments, i have a question: the radiation layer at the underside of the roof i thought you mentioned vapor barrier. if so, the roof sheathing is sandwiched between two layers of vapor barrier without air circulation. That would be a problem.....also the attic is constantly ventilated between soffit air intake where you added baffles and the ridge vent or high side vents; no vapor barrier on top of the attic floor insulation? . I want to improve the attic insulation in my single story florida home and mostly add a vapor barrier on top of the insulation. i have quite a few oversized cuts, J boxes etc that need to be sealed. souds like quite a project.....great video!
