Rockwall is fire profe as well

[@lizzieb6311]

I’d go Rockwool all day long over spray foam. A lot of spray foam being installed incorrectly…in the wrong places…and will trap moisture if the entire building envelope is not considered.

[@byronmiller800]

My understanding from a applicator is the open cell is porris and will let moisture thru, closed cell is actually often used on basement walls outside because it is a waterproofer

[@PineyGroveHomestead]

Our shop is closed cell and water still finds a way through!

[@earlyriser8998]

We did closed cell on the roof as we have trusses and limited access and wanted the extra strength. Open cell on all the external walls. We used 2x6 framing but didn't fill those bays. We also sprayed the garage walls and ceiling and it has been surprisingly comfortable here in Houston. The plastic and card board at 8:03 was done on our house too where the porch meets the roof. If I had known I would have insisted in blocking that in with plywood as the porch insulation is just a layer of melamin with foam in the inside. And plastic between the garage and the house to separate those two spaces. In a blown in insulation on the ceiling they actually don't close that space in and it remains at outside temperature. I have to feel like that carboard and plastic is the weakest link in my '50 year' insulation job. We decked the attic entirely and added an attic lift to carry boxes up and down. We decked it as soon as I saw how big it was and before they had done much else. The crew loved having a deck for all the additional work in the attic. Attic great for storage as it is inside the spray foamed ceiling and a conditioned space.

[@PineyGroveHomestead]

It's interesting how the plastic and cardboard creates that barrier! Thanks for sharing!

[@georgewest2096]

Do you have roof vents? i learned a lot more from this show then learned from our insulation contractor. thanks for the information.

[@PineyGroveHomestead]

No, it's a non-vented attic that will have conditioned air that will leak up from the rooms below because there will be no insulation behind the ceiling sheet rock! Thanks for watching.

[@bassmaster95231]

We spray foamed our new build in SC. Interior humidity has been an issue. I would add a while home dehumidifier while everything is still easily accessible.

[@Robertb00]

Just had the current remodel spray foamed and attic encapsulated. Because I chose to move all hvac to the attic from crawl space. Also because of vaulted ceiling needing the most R value as possible. I did have one small area that delaminated from roof decking and cause some condensation.

[@bradfigiel2203]

I recall a this old house episode where the spray foam was leveled with a glowing red wire that the ran down the studs. Like a hot knife thru butter. I would like to try spray foam at a cabin I have to get all the gaps sealed. Would prolly have to go closed from what you are saying. I would do the indoor vapor barrier regardless and let the hvac handle the humidity.

[@PineyGroveHomestead]

Mason sprayed closed cell in our shop...the video is linked in the description. It's all fascinating to us!

[@charlietuna1971]

Looking good. Open cell is fine in our climate zone. That's what we plan to use in our unvented attic. Although probably not required, it might be a good idea to paint the attic foam with an intumescent fire-retardant coating as an added measure of safety. I think i would also have put up something like a ZIP wall between the garage and house attics versus the plastic wall. I'm not sure how that plastic will hold up over time and how good the foam to plastic adhesion will be.

[@PineyGroveHomestead]

The house and garage attic are separated by a sheer OSB wall! Thanks for watching.

#truth

[@Tandmwilke]

The England issue seems to be 100 year old homes that they just retro-sprayed with foam without ensuring house integrity and the house not being built with foam in mind. Our builder uses open AND closed cell foam and has been doing so for years. House is open cell and shop is closed.

[@PineyGroveHomestead]

Same as ours! Our shop closed cell: kzbin.info/www/bejne/h6e5noF9aM1lhKc

[@stuartkorte1642]

Open cell requires a vapor barrier. Close cell seals. Open cell has to be thicker to achieve same R value.

[@nikkiharrison7290]

I am insulating my van with foam and doing a foam build what kind should I use?

[@PineyGroveHomestead]

A van is kinda small, so I would go with Closed Cell since the cost won't be too much more.

[@Digidoc316]

If your insurance company finds out you've spray foamed your home, they may drop you or refuse to pay on any fires. Foam burns and produces toxic fumes. Rock wool will not burn, is less expensive compared to spray foam, and can be cleanly cut as opposed to fiberglass batts. My personal choice is rock wool with foam gaskets.

[@LorraineDennison1960]

I have never seen either type of foam insulation used in Australia. Is there some reason why?

[@PineyGroveHomestead]

That's a good question! It's very common in the US.

[@erwinaddison2030]

Holy mold! Better install a ERV and a dehumidifier.

[@charlietuna1971]

That would be dependent on their blower door test. I believe they used standard house wrap and open cell. I'll be surprised if they have a blower door score below 3 which would then require some type of ERV. This house will probably be leaky enough to not require an ERV. Dehumidifiers should probably be standard in most Florida homes especially in the winter months however short our winters are here.

[@welewisiii]

closed cell only where it will touch cold or condensation i won’t use open cell anywhere in a build

[@richardbrookins5406]

In Bay County open cell must be covered for fire reasons as required by the building code.. Hazardous by-products of combustion are present whenever open cell is burned. Closed cell on the other hand will not burn. If you hold a torch to it, it will flame up some and then immediately go out when you remove the torch. That is why it is required in all open areas. I understand the cost issue but it is outweighed by the safety factor. Oh and never bet anything on Hiomeless Depot. The only thing you can count on them for is to screw it up.

[@PineyGroveHomestead]

I know many people in Bay County with spray foam this is just like ours in the attic.

@@PineyGroveHomestead Yep, for years they never enforced the rule. They started with me back in 2011 when I built my house.

While I'm not a fan of open cell...less insulation efficiency and no moisture barrier/sealing, but if it's the right thing for your area, that's fine.

[@PineyGroveHomestead]

It has higher R value than fiberglass batts. What are the moisture barrier/sealing issues? Fiberglass and blown in don't have those qualities??

[@jimbecker5675]

@@PineyGroveHomestead Open Cell provides no moisture/air barrier inherent just like fiberglass. It's porous by nature. If a true moisture barrier is required, it can be added just like with 'glass. But regional factors are always important so you should follow the advice of your local resources. Where I live, open cell is rare; closed cell is chosen for the sealing it provides as well as other factors. Please don't misunderstand...both are great products. I was just mentioning my preference. (I did spend a few years in the business a long time ago, but foam wasn't a thing then)

[@MongoMotors352]

I’ve read many bad things about open cell. In England, many home owners can’t get home insurance unless they remove it.

[@PineyGroveHomestead]

Do you know why?

[@MongoMotors352]

@ something to do with the Open cell allows, moisture to wick through and rot out the roof beams. Because you’re attic is completely closed and air-conditioned. This may not be a problem for you.

[@psychafunkapus]

@@PineyGroveHomestead In large part the roof wasn't sound and they got conned into foaming it without doing the necessary repairs first. Open cell does allow water absorption and it can hold water next to a roof leak and rot your wood. It can also mask the location of a leak as the water travels through the open cell matrix until it eventually gets something noticeably wet. There's a reason closed cell is 3x the cost.

[@PineyGroveHomestead]

​@@psychafunkapus Everything you said about open cell is true. Closed cell does the same thing but it's not quite as "spongy"

[@Utoobhero]

If they spray too little of the open cell, yes it allows moisture to collect around the wood, which does cause mold, but it looks like they wrapped the rafters pretty good.

[@philspd473]

For anybody concidering this please do yourself a huge favor and dont EVER spray foam directly to the underside of the roof like this.

[@PineyGroveHomestead]

Where else would you spray it?

[@philspd473]

@PineyGroveHomestead at least baffle the bays so your roof can breathe. All you did there was ensure your roof will overheat and fail prematurely...

[@PineyGroveHomestead]

@@philspd473 It's intentionally sealed so the attic gets conditioned air from HVAC.

[@philspd473]

@PineyGroveHomestead sorry to inform you but it will bite you in the tush down the line. You are doing a great job otherwise. I'm just saying you should have left airflow between the foam and plywood. Unfortunately it will cook your roof...

Thanks for the info

[@jeremyfogt6798]

Buy once cry once. I believe you will still need a vapor barrier.

[@PineyGroveHomestead]

Vapor barrier where?

[@charlietuna1971]

No interior vapor barriers in Florida's climate zones. We primarily cool down here so interior vapor is primarily removed by the air conditioner or dehumidifier. An interior barrier would make things worse here in Florida. Never make build decisions from watching a house build in another climate zone.

[@jeremyfogt6798]

@@PineyGroveHomestead Open cell foam wicks moisture so humid air from inside can move to sheathing so Plastic on the inside. This is one of the problems why insurance companies in England won't insure house with open cell foam but most of the problems they had there was due to poor install. Close cell foam is considered a moisture barrier. All that said if the drywallers do a good job and painted well it would be hard for moisture to get to the insulation, but it does happen. Probably not an issue since you are in Florida so moisture wouldn't migrate from inside to out. Just my thoughts, may be wrong.

[@jeremyfogt6798]

@@charlietuna1971 After remembering it is in FL I was thinking it vapor would never really migrate form in to out. Thanks for confirming.

[@mxb_se]

Yes, closed cell "helps" with racking strength, but no way should it be considered somehow structurally important in a hurricane zone. No way.

[@charlietuna1971]

Of course it can be considered as added strength. Most engineers just don't add it to the engineering calculations but they could if they wanted to. It's just added leg work on their part.
