Air sealing is such a benefit. People need to understand the convectional sealing superiority of closed cell foam. Well done Mike!

I really wish you and @buildshow (Matt), and that "crew" would sit down and have a frank discussion about all of this. I also think that many people would like to do this, but it still remains very expensive.

@@SprayJones I get it, but but I know there are some people in that camp that run into the same things you do debating if it's truly an air barrier, etc. We hear the same things you do and having someone like Matt and the Build Show crew, which have more reach (Subscribers) could go a long way in the mythbusting of these concerns and quelling some of the naysayers. thanks

Thanks for the rich content you provide Mike. I'm a true believer. This helps me further the conversation in my neck of the woods.

Great comment on outside airsealing...you need both. Even Risinger noted being disappointed in air infiltration if only relying on spray foam....the same as being disappointed if only relying on exterior systems. Need comprehensive and supportive actions. Great video!

Until all the gaps are sealed the building is not sealed. It takes multiple products to do that; this is self evident.

That happens. Good thing unlike wives & sweethearts looks don't matter as much.

Great information backed up by studies. However I think your point stated that proper thoughtful and complete installation of all the components of the system is of the utmost importance. No one product can do it all in a wood structure IMHO. On a side note/question? Do you have an opinion on properly installed radiant barrier? Permiable vs non permiable ? Taped n sealed w the required 25mm air spaced? Exterior or interior and or both? Blessings Sir and happy holidays Crawford out 🙏 🔥⚒️🧙🏼‍♂️

Thanks for watching and commenting how you do. I am not so familiar with the product you mention so I will have to learn more before commenting.

Yes you are Absolutely Right!!! Ever since the Price of Foam Insulation has dramatically increased, it Seems like Notable Online Contractors have Retaliated and Started to Proclaim Fibrous Insulation as As Good or Better than Foam Insulation. Obviously the Closed Foam is better for the 1st Line of Defense against Air Infiltration on the Interior. But contractors are upset that foam insulation is so expensive... In my humble opinion.

Every building material has gone up. We are included in all that. 10 years ago SPF was a lot cheaper than it is now and people still said then that SPF is too expensive. It is a head game not as much as a pocket book game.

QUESTION: If I choose to use Zip R-3 sheathing on exterior will 3 inches of spray foam have any problems with adhesion?

Awesome content! Subscribed. I'm putting spray foam in my house and contractor is half way done but recently his machine has been having problems so he is fix8ng it. While waiting for him to fix it, does this time break to fixing the machine impacts the quality of work? I'm doing a 2 inch SF. Thanks in advance

Not of the foam.

AeroBarrier will spray some stuff in the air and then press that stuff into all the cracks. No need for caulking at the seams then as I see it. For more, see _Matt Risinger: The one product I'd recommend for EVERY House!_

I have an AeroBarrier division at my company. It's great to tighten up the interior envelope when using fiberglass as a primary insulation type (🤮), but it has limitations. To get super tight seals, a lot of the work has to be done during construction. However, when we use it as an exterior envelope seal AFTER a full spray foam job (floor, walls, unvented roof), it works AMAZING. It is much less time consuming than caulking and it's a far better product than caulk for long term. It guarantees that nothing is missed and give a final ACH print out when it's done.

Another great video. My sprayfoam installer has installed open cell spray foam in my garage ceiling. Above are bedrooms. Is a vapor barrier required to cover the open cell spray foam on the ceiling of the garage by code?

@SprayJones

7 ай бұрын

How would I know since I have no clue where you are and what code is for your area? On a general physical note spraying to 3/4" OSB or plywood, the wood has enough vapor perm rating to be a vapor barrier. So the open cell would be fine in that situation.

What was the blue sealant shown on the video for sealing the stud to stud gaps? We've used acoustic sealant but it's a tube or sleeve and trowel. Haven't seen the spray seal around here. Would it be a perfect situation to have a double stud wall and be able to spray the exterior layer of that wall entirely right down onto the floor (With Acoustic under/above the plates)? We're doing a rough design right now and considering the double stud walls, (2x6 exterior and 2x4 interior) and it feels like the best practice would be to air seal the whole interior side of the exterior wall, right over the studs and floor plates. Interior wall would be responsible for hanging drywall and running electrical/plumbing etc so no loss on the exterior wall and no need for access later.

What do you say to people that are concerned with the condensation that accrues on the enteral windows? Worried (long term) that it will ruin the window seals?

@SprayJones

No. Get triple-pane windows.

the problem is how expensive it is... i just got spray foam done, 4" closed cell... was more expensive than ALL of the lumber for the entire building. and i did double stud with 2x6, a full load floor for the attic too. didnt skimp on the wood... the spray foam took basically ONE guy 3 days... took me all summer to frame it. and these guys quoted HALF of what every other sprayer was quoting. hopefully, worth the investment... i could build a whole extra house with batts for the price of it... excluding bureaucracy on the up side, they sprayed more like 5" and someplaces 6" thick.

One way to save is to do flash and batt, or 2" closed cell and the rest open cell.

@SprayJones

7 ай бұрын

The spray foam is the building. There is no comparison of a batt to SPF in how they work and what the end result will be 5-8 years from now. The "pains" you are expressing are only because your mindset is catching up to what you have bought. I live on a hill and the wind blows 3/4 of the time, batting is never an option SPF is the only way to do it, so one has to suck it up and do it.

Mike, Ive been watching many of your vids. After searching your vids, can't find my answer to my problem. New build residential and I have 12' covered porches. My tier two and tier three contractors tell me to build a 4 mil false wall vertically up from the ICF. I don't think I like the idea, I think its better to spray the upside of the porch coverings with open cell? Please give me your opinion. V/R.........Darin.

We do not spray into areas that do not need the SPF. Usually we separate off the house from outer areas... I am not sure this is what you are asking or not.

Will closed cell spray foam bond properly with plywood that’s been sealed with C2 brand “Guard” waterproofing product (which claims to change the nano structure of the wood)?

A contractor is finishing my all metal barndominium. He tells me that closed cell foam is the way to go, which seems to be true based on what i see here. Is any special prep required to get proper adhesion to the metal? Hes taliking about putting in seven inches to envelop the the purlins that support the roof sheeting so we do tget condensation. Does that make sense? Any issues with application while its cold outside (20 degrees F)?

Make a rediculously tight structure and then install a HRV which consumes purchased energy. Yup, that makes sense. If you don't have a forced air heating system, you then must install a complete duct system to distribute the conditioned air.
