Good point, although you probably know the actual physics while I simply think that sounds about right...

Lol, clever!

I know that this is a topic. I have had several people inquire about this recently, so I took a Fundamental of Bugs, Mold, and Rot seminar. Living in Maryland, our houses are in the mid-range in terms of being susceptible to termite problems. In my opinion, when using two-part spray foam, leaving an area uninsulated is a waste of resources. There are other methods to seal the rim joist, such as one-part spray foam and then covering it with batts. I plan to continue learning about this concern and discuss potential problems with my customers.

Hi there! I wish I could envision your scenario. Feel free to send me an email to [email protected] with any photos you can share and perhaps your address if it is visible from Google Earth and I can take a look to see if I can give you some advice.

Yes. A small inconvenience for a lifetime of benefits.

You're welcome. Replace them if you want to for operability, beauty, maybe even to block heat from the sun (although blinds can do that), but if you want to improve your comfort - you gotta take a trip to your attic.

Absolutely, it’s a major source of leakage.

Hi. If your current fan is properly ducted to the outside you won't need to go into the attic. You can carefully disconnect the duct and reconnect to the new fan. In my opinion, I would take out the old fan and get a completely new fan. Just use the existing wiring. Whichever fan you choose, watch a video on that specific model. If you use the one in this video, be prepared to bend the duct connection to make it into an oval shape which is not a big deal, but you do have to make sure the duct is clear of the damper, otherwise it will get stuck and the fan won't work. I believe the fan you have has a larger outlet (standard, and due to the higher profile) so you may want to find one that matches. Hope this helps.

Thanks. I plan on purchasing the same Panasonic, just a newer model that is available.

@homeairleakagetest thanks for this!

You’re welcome!

Hey, honestly I don't recall. But, here is how to check how much you need: Board Feet - for example if you buy a froth pak that yields 620 board feet that is equal to 620 12" x 12" x 1" 'thick areas. So you have to do some math. The R-value is around 6 per 1".

@ thank you!!

@ is that technically equivalent to 1sq ft right?

Thank you!

In that case you might have to go through the floor. I did that once and did a short video about it.

@@homeairleakagetest i’ll check out, thank you!

Hey, depends on how cold it gets around you. If you can store it indoors and then break it out at the last minute you will be fine. Do all of your prep work so that when you bring it out you are ready to spray.

You got this! We’re all rooting for you, enjoy the savings and the comfort, but maybe take a break every now and then. 😉

No. Floors don’t breathe. They need to be kept dry and clean.

It absolutely will. No doubt. All the best and thanks for sharing and watching!

You cannot see, open, use or show it off to friends, so yes, insulation is not as desirable. But, it is the most important home improvement project you can do (if you need it). Thanks for watching!

You're welcome and there are so many people out there that do not know this important information so it makes me so happy to know that you found it and it helped open your eyes to the right pathway to better comfort and efficiency. Thank you for watching!!

I don't know, but I love cats.

Feel free to suggest any ideas to improve the problem. Thanks for watching!

In this case, the inside was closed off by a drywall finish so it made more sense to seal and insulate from the outside. If the location of the overhang is adjacent to the unfinished part of the basement then you can absolutely seal and insulate from the inside.

@homeairleakagetest no mine is blocked by sheetrock too. Figured cutting sheetrock is still easier and quicker than what you've done in video. Guess not?

That is a really good point. For some it may be easier. I always think about the painting and trying to match everything. Doing demo on the outside is a lot more forgiving. If you are skilled in that arena, then doing it from the inside may be the better way to go.

@@homeairleakagetest no I'm not skilled. But I don't care about my basement since sheetrock is in unfinished part. I was just wondering if the problem can be resolved that way too

i figure most people want to get up there and get going as soon as possible...

@@homeairleakagetest was just up there myself and felt pretty confident thanks to you.

awesome! glad to hear!

welcome!

So glad that it helped! You're welcome.

Why not get to it right away?

9 out of 10 houses are under-insulated so it would not surprise me if yours falls into the majority! Thank you so much for watching and I am glad my videos are helping you!

You are not along my friend. That's the point of the video - EXACTLY!!

Hello. The roof adhesive? Any roofing cement should do the trick.

Watch a video that wastes your time, write a comment that wastes more time - definition of insanity.

@@homeairleakagetest insanity is to clickbait people and to show nothing.

I appreciate that Woody. So glad it helps! I didn’t know anything about this stuff and I wish I did. Would have saved so much!

You will be fine. Take your time. I do it every day and I am 230

@ thank you for your reply makes me feel better since I didn’t know how much weight a single joists can hold. Would you say is safe to put plywood and used the attic for storage ?

It is completely safe yes. Personally, I am not a big fan of storing things in the attic. I place a higher priority on sealing and maintaining the insulation's level all across the entire area. If you have to, limit the area you plan to use for storage or better yet, build up a platform so it is above the insulation line.

I don’t know exactly technically. As far as smell, it seems to be different for everyone depending on sensitivity and weather.

You are in for a much warmer winter (assuming you live in a cold climate). Glad you watched!

I put a link in the description! AKA: FSK Tape.

@@homeairleakagetestlol awesome that was so fast i looked in description and i was like duh he has the link for it you should have looked better. Came to delete my comment, and saw you reply. Thanks i appreciate it. Good stuff. I been finish out attic and i used 4” polyiso i had to cut each 4’x8’ piece down to fit between each rafter, i have air gap from soffit to the new attic, there i created a air gap chute of bubble foil up to few inches below ridge vent. Air will flow all way up, the cathedral bays only 2x6, so air gap and 4 inch polyiso tight between rafter, another half inch foam on top fills each bay. I then used foam board adhesive to go along edge to seal any gaps, and then using seal tap on top of that. So far when temps outside dropped to 36 its been staying 60 with no hvac yet and i still have couple sections of ceiling left to put in batts. I got r38 some r49, faced and got those great deal 70 bucks normally 120 at big box, and then i got killer deal on r30 4’ x 25’ non faced insulation batt rolls for 40 bucks each! I just cut and putting that on top of the r38/r49 talk about insulated 🤪. Only thing i need to do is cut some gaps in the bubble foil at ridgecap at first i went all the way up, and found there needs to be gap so air in the new attic can escape out when it gets warm. Once i found that i did rest with a few inch gap at the top for that bubble foil.

Dude, you are a genius! Great job my friend!!!

@@homeairleakagetest thanks! Ive gotten great info off your channel, greatly appreciated.

I believe I did get it from the Depot. If you cannot find, buy 1" and add layers to get you where you need to be!

Amazing! I hope it helps him solve his issue. Thank you so much for sharing!

I agree if the fan is already properly vented through the roof, soffit or gable wall. Often times that is not the case so a trip to the attic is necessary. Yesterday, I was able to install one that had a properly terminated duct through the roof and I never needed to go to the attic, but I did anyways.

Thank you sir!

You got it! Great move!!

Thanks for your comment! All the best with your new endeavor!!

Thanks for sharing the details! Does your current fan duct straight through the roof, or does it vent horizontally to an exterior wall? Can you attach the duct to the flange before securing that part of the fan? That is how I like to overcome the small clearance. I also find that once I cut the hole for the Panasonic, it gives me more room to maneuver the duct and get things set up right. I speak from installing the fan in a first floor bathroom with no access from above. Only the preexisting duct to make a new connection.

@@homeairleakagetest The tube goes horizontal to the wall and a vent. But my issue is the flange on the output tube flange and the power box are very close to the flange that would go against the drywall. I am mouting like a retro so the sqaure body flange needs to be on the outside of the drywall and the drywall needs to side between that and thge output flange and power box bodies. I guess because the flange is tapered, I can cut some more drywall out so if is missing near the fan box body. The power box might have to be left off. The fan has a elliptical output adapter. I have bought the adapeter to reduce it to 3" which I assume is the tube size is. There is only enough height for a 3" tube in the cavity. At the wall, I believe the tube is disconencted from the outside vent so the vent will have to be removed to fish the tube back or replaced. It is ony about 3-4 feet to the wall.

I can send a sketch if there is some way to upload

I understand where you’re coming from and appreciate your perspective. Based on my experience with numerous homes, I’ve often observed this kind of discoloration where airflow paths consistently run through insulation, carrying dust and dirt over time. This house had an induced draft furnace with no signs of puffback or combustion residue during inspection. Air leakage tends to cause this pattern, especially in older homes with high infiltration rates. I’d be glad to discuss further if you’d like to explore the factors I typically assess in these situations, including a blower door test and feedback from the occupant of the home.

@homeairleakagetest that was an oil furnace. Technically the draft is induced but it's positive pressure. It's not the same as a gas furnace with an inducer. If you don't maintain the oil burner it will blow out soot and that's exactly what happened here.

Thanks for sharing your experience! Old single-pane aluminum windows definitely have their challenges-especially with the issues you described, like condensation and the chill from cold surfaces. Replacing them with new windows can make a big difference in comfort for sure, especially when it comes to that 'cold draft' effect from the glass and frames cooling the air around them. What’s interesting is that, while replacing windows can improve comfort, sealing up the attic, walls, and other areas where air leaks occur can often reduce drafts and improve overall warmth even more than windows alone. Combining air sealing with efficient windows is the ideal way to balance energy savings and comfort. Sounds like your new windows added a nice boost to both comfort and aesthetics!

lol😂

Ignorant. Duct tape doesn’t last vs UL 181/FSK tape or butyl/mastic tape. Add heat and/or moisture and it can fail in years not decades causing tons of wasted energy until the problem is found.

I was making joke about the duct tape on the ducts(which is what he was showing). Not for building plenums and trunk lines buddy😎😂
