How Thick Can Spray Foam Insulation Be?

Perfect explanation of the differences, thanks

That Huntsman HFO looks so beautiful. I'm about a set into mine so far and absolutely love it so far.

The knowledge is great

Thank you for your awesome instructional videos!!

Thank you, sir! This is the information you recommended for me to a tee.

I live at 8000 feet in Wyoming. We have temperatures in the winter from typically 28° down to 30 below for a few weeks every winter. What would you recommend for a thickness on walls and ceilings for a metal build with concrete slab in floor heating. Close sell, Insulation.

Do you guys do any work in Montana?

Awesome helpful video: few questions for homes in US Tx, with Closed Cell application in attics do you need to remove the baffles or do these typically stay in place after the foam install? Also with regards to getting a conditioned attic space with installing closed spray foam, what is best method to dealing with HVAC air and gas furnaces setup in attics in the south climate zone 3? Since these gas furnaces are installed in attics and will need air intake! Any way to get around this issue before installing closed cell foam! Also is there any major differences between brands/companies manufacturers for closed cell foam of best to worst rankings? Thank you

I am looking to have my attic insulated. It is in Southwest Florida on the coast and it is a fairly shallow attic space, approximately 4’ high at the ridge. The house was built in 1964 and is a block house with a truss roof. What do you recommend for insulating that space? Also, I am having every window and door replaced with hurricane impact windows and doors in the next three months. I was told a sealed and spray foam insulation on the underside of the roof deck is the best option.

Do you recommend open or closed cell for application on the ceiling of a vented attic? Attic needs to remain vented because I have natural gas lines in the attic. The home is in Texas where we have serious summer heat. Thanks!

I have a house built in the mountains of NH in 1973. Paying circa 900-1200/month . Thinking about pulling down the vaulted ceiling drywall and spray the 2x6 rafters with closed cell foam. Curious if you feel that 5” of foam will be enough and what will be the cost impact of my heating?

When layering closed-cell foam, how is the bonding between layers? If pulled apart, would it break at the layer junction?

I live in a 100 year old cold house and having a problem with smart mice. Could a hot spice be add to the foam to repel the mice. The basement is a stone foundation and 1st and 2nd are lath and plaster. I live in the Toronto Ontario area.

Unrelated question. I'm planning to use some freezeless hose bibs on a pole barn and use closed cell for the insulation. Will I be able to unthread the hose bib for future service or I need to cut out the drywall and cut the foam out in order to replace it if needed?

Im in Texas, trying to figure out if its possible to spray foam an attic on a 17 year old finished home. We bought the house 8 months ago and then i got into some building science and want to spray foam the under side of the roof deck so my attic is in the conditioned space.

Is there any difference between the closed cell foam you spray and the closed cell foam they sellon like Amazon other than experience im disabled live in uninsulated 5th wheel in Texas and heat is killing me and my wife would love to have a professional come in but with my income that not going to happen if we want to eat and do you recommend a brand if any for a retired excavator operator thanks in advance

What are your thoughts on 3" installs? Should I require my installer to do 2 and 1 or just be ok with 3" at one pass?

I’ve seen foam products whose listing / labeling restricts foam thickness to 2”. I’ve also seen foam panels manufactured as thick as 6”. I say: follow the instructions! Foam generally requires moisture for the chemical reaction, and foams vary as to the “strength” of their bubbles. Spraying too thick will result in bad results: soggy, uncured cores, reduced bubble size (poor insulating), or distortion of building components.

I get that all the time in Texas. “Fold over some baffles” “Jamb a Batt in there”. How bout you build me a proper 5 sided assembly to spray to!

Cardboard Blocking? Builders, jeezzzz!
