@@dtemp132trying to rip out knob and tube wiring will probably be costly and cause a lot of damage in and plaster and lathe house. Nothing wrong with leaving it in place just disconnect and stop using.
We will be insulating our new home construction (ohio) in a couple months. I have gotten two quotes based on the insulators recommendations. One recommended .5” spray foam and then fiberglass. The other recommended .5” spray and then cellulose. I am confused why they would recommend this if moisture will build up because the 2” minimum isn’t being met…. What am I missing???
What about spray foam in existing houses? How to get it inside the walls with existing fiberglass insulation? How is it done. I've seen ads for USA insulation where they show the process. Thoughts on this kind of insulation improvement on a home?
Curious on a crawl space floor that is gravel. Will the spray foam adhere to it to point where if you had to crawl on it 3 or 4 times a year it would it stay together or would this not be a correct application for that scenario. At present 2 inch foam board that is breaking apart from the years of crawling on it it to do some plumbing and electrical work off and on thru the years
@@BZ1340 I would think, since it's a liquid being sprayed, it would bind to the individual gravel rocks, stabilizing them, and eliminating or reducing movement that would agitate tearing at the material...making sure there's enough thickness. Then, the only worry would be erosion under the surface. But compression of the foam might be a concern. I suspect it would wear like any plastic...developing hills and valleys over time.
Anyone with one eye and half a brain should easily see and understand the structural , thermal ,air and vapor resistance of properly applied closed cell spray foam (as you teach) to a building; Especially a wood structure. I am almost to a point of a major remodel on my current home and am seriously considering demo to bare studs and have my entire structure heavy spray foamed with closed cell in several lifts of application. I am a retired builder of thousands of structures, I absolutely see no issues with closed cell spray foam. Some may say the cost is prohibitive, I say to those folks to get your line of thinking straightened out and learn where the priorities are on building a structurally sound and insulated building . I promise you , any other form of insulation of wood structure is pissing your money away. Period. Keep on educating the TH-cam masses.

Umm…PVC windows, plumbing, wiring, stuffed animals, shoes, shower curtain,….ad nauseum. You can try, but fire takes it all. Makes horrible smoke and pollution. Have you even considered the cars in your garage? Acceptable risk, might be the term I’m thinking of.
Always enjoy your videos Mike! Quality stuff no matter what the topic, thank you!
Thank you. Wait until you see the next phase of our career with media.
@@SprayJones can't wait . I watch every video you post
Thank you!
Used foam in my house built in 86’, still good.
Great content always! Do you prefer BASF material ???
Yes - they have the programs and help we need.
Can you spray onto knob and tube wiring?
If knob and tube wiring still exists anywhere, it should be ripped out and replaced.
@dtemp132 only if you can afford 50k to do that, haha wild
No

You are talking about open cell half pound foam. That is what .5 means
@@SprayJones I was told a half inch closed sell foam.
@@Zaclauck That is completely wrong. The nails won't even be covered. Watch the 2 videos I have on flash and batt.

pull the drywall, Foam, then reinstall drywall/mud/tape/paint
Agreed.

Yes - go watch the "in contact with ground" video, second half we walk on the foam..
@@SprayJones Thanks… I think I saw that vid. I just wondered what kind of punishment the foam can take crawling all over it in a crawl space.

@@BZ1340 Pretty amazing as long as you aren't jumping on it.
People say a lot of things, many maybe most are wrong yet they persist even after being corrected.

Well said! Yes we plan to put the education and exposure of SPF into a whole new realm starting this year.
You will turn your building into chemical waste and it is not healthy to stay in it.
No thank you. I'll take mineral wool any day over any material that emits toxic fumes when on fire, which is basically everything else.

They keep pushing electric vehicles to . Why ?
Control. When the curfews come in.... and they would....you will be at their mercy.
