Spray Foam Insulation - Open or closed cell?

[gordonitis]

Perhaps one could open a window or door for fresh air.

@gordonitis You would have to leave it open for the house to be healthy to live in.

Builders= geniuses...definitely not scam artists. And they definitely don't think they know EVERYTHING. According to this guy, he's the only generalist in the world that knows more than the specialists. Good theory. Fail. Maybe I'll go to a general practicioner next time I have an eye problem.

@kurtbuc Generalist? The builders I know are geniouses, my dad was tested in the 60's at 146points, he has been building since the 70's. I helped for over a decade and got my HVAC license,and BPI license because I liked the energy side of homes. Scam artist builders don't make it too long, because they will use stuff like spray foam.

@kurtbuc You seem to know alot about home energy for an insulator, what is your license # so I can look it up? Oops...........keep fucking people bud, you and all the other spray foamers will only do yourselves in. Peaked at 3% of teh insulation market.....now its going downhill again! LOL LOL LOL.

How would that be deadly in an electric/heat pump house? Doesn't make sense. Do you think the house will run out of oxygen. That is funny if you think that.

@kurtbuc Homes need to breathe, not just for oxygen, but to remove all of the VOC and indoor air pollutants that can cause cancer among many other negative health effects. This is why ASHREA has for decades required .35 air changes/hour. Foamer Gomers keep going around regurgitating what their foam distributor taught them in a weekend class. When you build homes and you want to sleep at night, better not build them too tight, or rely on a fan motor to bring fresh air in, people can and will pay

btw a few years ago I went ahead and got a home performance license to rate our homes and save a bit more money. #CAN06347. I do all of our blower door testing/duct testing thermal imaging, energy useage recording. When you foam a home too tight, what do you do for fresh air? Hope the electricity doesnt EVER go out? Hope your fresh air system never fails? Homes that breathe on their own can't be beat for occupant safety, mechanical fresh air WILL fail, if the occupant doesnt' catch it, deadly

The person who wrote the comments below is very ignorant of insulation & the use & performance of spray foam. My company has insulated over 3,000 homes so I know what works in the real world. Spray foam is superior no doubt. I do every type of insulation there is & I would have no other type in my own house.

@kurtbuc That is close to being a 2nd generation home builder with thousands of home built. Except we measure energy useage after the homes are built. Foam performs the worst of all insulations. We insulate to R-60, we don't rely on a chinese motor to bring in fresh air, and we save homeowners not only money on energy using loose-fills(r-60, no retarded conditioning of attic space) which has been tested and proven, we save them mortgage interest on the lower cost insulation. Need the facts?

[HomeEnergyNow]

I have BUILT over 1000 homes.As you know, the insulator is one of the dumbest people to show up on our jobsite.You prove this. As a builder years ago I decided it would be wise to get an energy license #CAN06347. Manual J, BPI, HERS all show R-60 loosefill to be superior to ANY foam setup. Conditioning an attic is stupid, you can prove the stupidity with any three options above. I have built/tested, built/tested. Foam IS the worst choice of insulation. Sir, like most insulators you're an idiot.

[HomeEnergyNow]

The contractors at the home shows like that, are the ones that need the work the most! LOL Excuse me little idiot with the name badge, but air infiltration IS REQUIRED!!!!!!! Ever house REQUIRES all new air every three hours, and any home can be made that tight for a less than the price of that dweebs shirt. You can't even install EITHER FOAM to meet todays R-38 ceilings. R-value per inch doesn't matter, loose fills go to R-60.............THAT MATTERS!
