Spray foam quote...wow!

[78C-10]

Hello everyone, I got my first quote today for 2" closed cell foam for my 30x40x10, northern Illinois. All four walls and gables, no ceiling, $3200! Does this sound about right? Seems high to me, I am going to make a few more calls but thought I'd share my first quote.

 

[theoldwizard1]

Just the four walls is 1,400 sq ft.

That is $2.29 per sq. ft.

 

[mopar65]

not really that high.my shop is 48x72x12 fully sprayed 2" $13,000 but it is unbelievable how easy it is to heat.

Am I doing this wrong?
30+30+40+40=140 and
140*10=1400
How did you come up with 12000?

 

[cyamaha2007]

36x56x14h was 4300 for 2in closed cell foam

 

[Jbullfrog]

Mine was a $1.25/in / square foot, 2 years ago.

 

[jake00]

Just the four walls is 12,000 sq ft.

That is $0.27 per sq. ft.

I'm figuring the walls are 300+300+400+400 =1400

 

[Bib Overalls]

$2 a sq ft for 2" but they actually gave me about 3+". Very pleased.

 

[stonewellmark]

R-30 fiberglass runs from $1.50 to $2 sqft. if that helps, and you get to install it.

 

[slice]

the pay off will happen for yrs to Come

 

[46Nash]

Thats better than my $7800 blown cellulose quote!

 

[zeebad1]

Mine was $1.65/sq. ft, for 2" on the sidewalls, and 3" on the roof.

Seemed like a lot at the time, but probably the best $14,000.00 I have spent on the building.

Best "bang for the buck," as far as insulation goes.


Please give Slagel Insulation a call. They're in central IL., but come up north regularly.

r-30 on the walls? and what's the r rating of 2" foam?

 

[78C-10]

The R rating of 2" of foam is about R14. I'm also looking at the air and hopefully somewhat water tightness of the building. We had a lot of wind and rain here yestersday and since this building is relatively new this was the first time I saw all of the leaks in the building. I guess I could spend the time to seal the leaks myself and continue with FG batts. I was curious what a spray foam job would cost, may still go that route, just need to save my nickles and dimes.

 

[awdblazer]

wow i got quoted 4 dollars a square foot for r20 spray in

DO IT!
FG pretty much *****, any air movement at all in the wall cavity or "stud bay" rapidly diminishes the rated "R" value of FG. It is nearly inpossible to eliminate all of this "air movement" even with "house wrap" and caulking.
Energy costs will NEVER be cheaper than it is today, think about it.

 

[jeepman1]

i checked recently and my guy said 3.75 a square ft for closed cell. open was 2.75. he did say that he would fill a 2x6 stud space.

you might also check into utility rebates for insulation. in my area i would get a max of 1500 dollars back. plus the endless savings each month!

Stopping the air infiltration makes more difference than the variation in R-value rating.

Don't kid yourself. You'll never get all of the cracks & crevises plugged.
It's like the old adage...."spend a dollar to save a dime!"

If you want to see a 3 year old example of spray foam, shoot me a message.
I'm 100 mi. west of Chicago, and am so glad I went with the spray foam.We had the wind & rain yesterday, and I was in the shop all day.
No drafts whatsoever.

Bad math on my part !

 

[theoldwizard1]

36x56x14h was 4300 for 2in closed cell foam

$1.67/ sq ft

 

[wedge40]

I believe they usually price per square foot per inch of thickness.
To op. That seems like a pretty good price. I'll post back. I'm waiting on a second quote to make my descision to have it done this spring.

$3200 sounds like a good price. Spray foam is the best but expensive. My addition was so large I couldn't afford foam. I did regular FG ins.

 

[Pcoghlan]

Just throwing this in as I got a quote for sprayed in foam and nearly had a heart attack. I guess i just didn't think about what it would cost.

Anyway, I am blowing in Atticat (http://insulation.owenscorning.com/...atticat-expanding-blown-in-insulation-system/) which you can get from Home Depot complete with free machine to blow it in. Total cost for 28*36 with 14' 6" walls is $1,000 to R-25 protection.

I am sure there are better solutions but this will work for me.

People need to remember, everyone has different budgets and needs. I don't see the massive difference between this and something that is 5-7 times the cost. Is the more expensive option better, absolutely, do I need it, no.

R-25 insulation works for me.

 

[BrianC636]

I did 4" on the walls and 6" on the roof deck on my 40 x 64 x 12. While it was open cell, it cost me around 5500.

I did it at the same time as the house so I worked a better deal. Call several places and don't hide that you are shopping them. They will move on pricing.

I am REALLY pleased with how mine turned out and how simple it is to heat.

You have any photos of that open cell?

[OldNeons]

the problem is with blown in or fiberglass batts- you NEVER realize the rated R value. Sealing up the building airtight with a thin layer of foam and then using blow in or batts is probably the most cost effective option overall if you look at true achieved insulation values and long term costs. That's the route I'll be going in my new building (if I don't go all ICF). Good luck, stay warm!

Thanks, apparently I did see that, as I commented on the foam. Just didn't realize it was open cell.

also check with your local utility for any kind of rebates ,I had blown cellulose put in last summer and half was paid by my local utility Co.

 

[Kevin54]

Doesn't sound too bad to me. I had a quote of $800 for 576 sq. ft. in doing the floor of our family room in our crawlspace. That comes out to $1.39/sq.ft.

 

[green.bubbly]

50 cents per square foot. I had found some R30 being discontinued at HD for 30 cents a few months ago.

I recently had a decision to make on what insulation to use on a basement area which I was finishing out with 2x4 walls. After calling a couple of other contractors (electrical, plumbing) I knew and trusted to get their recommendations for an insulation contractor (I asked them who they would use if they were building), I narrowed it down to two. One really didn't want to do this size job unless they were also going to do the rest of the work (rough in, sheet rock, etc.), so it was an easy decision to use the other gentleman, who was very good to work with.

Here is what I learned from the process. The insulation contractor I used explained that R values alone could be misleading. His example was this in the form of a question-what is the R value of an ice cube? I replied zero, and he then asked me how it is that an igloo can keep you warm? His point was that air infiltration was also critical, and that a lower R value with a good air infiltration barrier will stay warmer than a higher R value with less of an air infiltration barrier.

Given this, it made it pretty easy to choose a skim coat of close cell insulation even thought it was more expensive than open cell, and then fill the wall cavity with blown in out to the studs. The total surface area was about 1200 square feet, and I'm estimating that they did at least 1 1/2"s of foam. By far this is the most comfortable room in our home.

I looked at the cost ($1900) as an investment, and I only wish my entire house was built this way. If I every build anything in the future, this is the only way I would do it, unless something better comes along.
