spray foam

[capt jack]

I'm in the process of converting an existing camper "carport" into a shop (my existing one is outgrown). Its 20'x36' 12 ft. tall. I've already poured the slab, I'll be walling it in soon. I thought I wanted to have the interior sprayed with the semi ridgid foam insulation (looks like the stuff that comes out of spray cans). The only guy I've talked to so far priced it at $1.50 Sq. ft. of wall/ceiling area. About $3000 , seems pretty high to me. What about it guys, anyone here had it done in the last few months that can tell me if thats a correct price? My neighbor has a shop twice as big as mine and said his was $2000 but that was 4 years ago. I do plan to get more bids, but not many choices around here.
Thanks! Jack

I have no idea about the cost, but what material will you be spraying it onto; i.e, wood or metal walls and ceiling? I've heard nothing but bad stories about using it on metal, but if it's wood, I think it might be good.

I looked into it last fall. I forget the prices but I do recall that it was the most expensive option for what I was doing.
There were even do it yourself kits on the net. That might give you an idea about the low end of the price scale.

A friend of mine is a contractor that manages lots of duplex builds and just finished a new house for himself.
One of the things he did was use that on his house. not sure of all the details, but he has no vents at all in the roof and the house gets complete cooling.

This will serve as an insulation barrier and will work well.. BUT is has to go against wood. I think Eddie Walker can add more info here...


Later,

Hi,

Yes, you can DIY with kits and more reasonable than having it done.

Couple of expamples here;

Renovation Nation on Discovery Channel just had a segment on Concrete Foam insulation. Non toxic, fireproof, mold & critter proof. The videos are at Airkrete or Renovation Nation : Planet Green

This might be a DIY job if you have the desire to become an installer.

paid $1.00 sq. ft. in 04.

$1.40 to $1.60 per foot in the Atlanta area.

I paid $2000 for my entire 1800sqft house back in 2001. That price included me shaving all the excess down to stud level instead of the installer. At that time, that was about 3x the price of doing my own fiberglass batt.

I will never use any other insulation again. the house is so tight now that the energy recovery unit (fresh air) runs more than the furnace in the dead of our Wisconsin winters. In the years since, my gas savings has more than made up for the extra cost of the insulation.

As for the metal buildings, I beleive there is a bonding product, similar to an undercoating, that they can apply first that bonds well to the foam.

Bird, could you give more details on this? I recently built a 40'Wx60'Dx18'H metal shop. The builder talked me into using the closed cell foam insulation as it was "only about 15% more money than the batt and provided much more strength".. Beings I live on the Tx coast the additional strength the close cell would provide seemed to be the right choice.
Well the first estimate was $12K. I looked into do-it-yourself kits but it would take so many kits I would spend close to same amount of money and me doing all the work. So right now the shop is not insulated seems at this point short of pulling the metal off the building the spray foam is my only option?

Thanks for any advice on this.

Chuck.
