That's about correct ....

I'm doing a remodel currently -- have to overspray old foam w/ 1" + -- and fully foam an addition. I'm paying a bit more because of the prep.

People forget the cost of the prep and the basic cost of the truck. Bigger players have crew to prep and the spray guys ... spray. The cheapest is when you use them for full days ... that's why I did a flash and batt on a remodel years ago .... they could come in a get it done in one day .. the cost of the truck and team for the second partial day made the cost past what was reasonable at that time.

 

[Kaizen]

I’m always just shocked by the cost. If I was in my garage all the time it’s a good choice. What’s the average roi? Wonder how it compares to zip system and rock wool?
Saw a cool time saver prep thing on tv. They taped the edges of the studs with masking tape. So instead of having to scrape them they just pulled the tape.

Nice, I did this to my house and would not even think about doing anything else. While comparable peoples electric bills are in the 450 plus in the peak of summer, mine is hovering around 170 for a similar size house. It works great.

 

[NotOrganized]

Looks great! What are you planning to cover the walls with? I need to do the same soon.

 

[tricountytrail]

Plan is to not cover it with anything right now.

While i can't speak for other's costs, i agree on spray foaming homes. Mine is very reasonable to air condition for such a large house. We did flash and batt.

You may already be aware but the spray foam is not very resistant to flames. It will need to be covered as soon as possible.

I have been doing flash and batt in each room as we have been renovating over the years, its unbelievable how much of a different it makes.

 

[purediesel]

Did you have a company spray it? For the cost I can't justify the spray foam for my shop. My best quote came in at $7200 and my highest at $10,400. Shop is a 50'x80' with 16' ceilings, 3 man doors, 24'x14' and 16'x14' overhead garage doors. For around $6000 I can do the flash and batt with studding the walls out, electrical (not including getting service to the barn) 8' tall osb all around and end up with around an R33 wall.

Its not just the cost. You need to look at how you are heating it what insulation is in the man doors, garage doors, and windows, what temp and which area are you in. How are you doing ceiling? Add 3-4 k or more to line it metal.
Every shop is different.

Any hot work or welding I will place either osb or metal in that area.
There won't be any open flame source in building.

 

[NotOrganized]

Foam will yellow with the sun or reflected sun. Seems to degrade it over time. You might want to verify this with the foam provider.

There are foam types that do not need to be covered. I believe even some open.

I had a fire in 2012 -- the house had been foamed (closed) in the early 90's when renovated by the previous owner. The fire started outside and destroyed a two story wood clad addition .... cedar siding and roof. The main structure was stone.

Interestingly -- the fire was able to burn though the wood windows and part of the roof/wall at the juncture of the two. The fire worked it's way up the wall and when it hit the roof overhang was able to eat into that area.

Surprisingly -- the foam did not burn, It sort of melted in one area -- and got into the building. We could not tell if the fire melted though the foam or if there was a gap in the foam. It was a very small area -- not even big enough for my hand.

I took some of the foam and tried to light it with a propane torch -- no go.

There is a video out there where you see a whole building go up -- but, they light a fire inside a closed building with no windows .. at some point ..way above 1000 degrees .. it flashes over. Now, that may be a problem in a high rise ... but in a house?

Actually -- all agreed that the foam saved the structure (addition) ... had the foam not been there the air passages would have allowed the fire to undercut the roof deck and it would have all gone up -- taking the roof of the historic stone building.

It will yellow when exposed to uv it can be painted with a latex paint to keep it white I will worry about that later if it bothers me.

 

[walrus]

I'll bet that will be a comfortable place to work and quiet also. After having a fire in my shop that went out because of tightness and wall covering I'd get it covered but thats just me. Enjoy

That is going to be nice and cozy. Really like the sink too!

And the foam isn't just insulation and vapour barrier, it also adds a huge amount of stiffness to the building.

I’m not so sure foam is a good sound deadener, we sprayed our bathroom walls before drywalling the inside walls. Seemed to be zero benefit in cutting down noise. Now I am happy with the outside wall performance

 

[kj_mustang]

Closed cell foam deadens transmitted sounds of metal walls and roof considerably.

 

[Ak Jim]

People on the next road over from ours had a big metal building that was spray foamed. They were doing some fireworks out in the driveway. Not sure what exactly went wrong but one of the fireworks went into the open garage door. Notice I said they HAD a metal foam insulated shop.

 

[rburke65]

Well I would think that logic would dictate that, if you have the bucks, ya can’t beat spray foam. Sound deadener, stiffens structure, insulate, VB, seals gaps. Far superior.

 

[Steve in UT]

My Brother spray foamed his house and loves the insulation factor but hates the sound transfer characteristics. Says he can hear people whispering outside.

 

[coalminer16]

I have 3 inches on the 2x4 stud walls where I sleep. While putting 41 dump trucks of fill for the new shop while I was sleeping as I work night shift I slept fine. Mind you I have 3 sets of shades on the window and a white noise maker in the room but the trucks were 30 feet outside the room.

And the shop with a metal roof was deafening in rain - not anymore.

I also tried to light up a broken off chunk of foam and it doesn't do anything. Yes a hot ember from torching will melt through it. And within months I saw yellow fading on exposed foam. Had a odd cut osb board leaning on the wall and it left a white mark where it was covered. I found a deal on 1/2 inch fireblock osb board and painted with oil based white primer walls only. $7 a sheet of 4x8. Wasn't going to cover the walls either until I found the deal on the osb fireblock. Helps get closer to code for the romex wire in my area.

I can't say I've noticed that at all - even with open cell.

We just finished our first year in our new house, I spray foamed the walls and a 2" lid on top of the drywall ceiling in the attic and blown in cellulose on top of that. Our driveway was gravel, you could not hear anyone driving up the drive (even the dog, who doesn't miss anything) the house is pretty sound proof.
