Whats the going Rate to have Spray Foam Insulation Applied???

[Highway Yacht]

Trying to get all my ducks in a row and figure out my budget for the conversion. Thinking I am leaning towards the Spray Foam Insulation over Foam Board at the moment. Was just wondering what kind of dollar figure most of you guys spent to have this done. Especially the ones that had it done in my part of the Country (North Carolina) as I know pricing varies according to regions. Did you contact a company that does home insulation to do it, or did you have a company do it that specializes in refridgerated trailers? Any info would be helpful. Thanks Jimmy

I asked a home insulation company about the cost for their spray foam.  $1 per inch of thickness per square foot.  They typically don't fill the cavity completely to avoid removing the excess, but they are used to dealing with 3 1/2" thick cavities.

This is in Minneapolis, Minnesota.  They said would probably give a discount for bringing the bus to them.

I have had a lot of coaches foamed at my shop. The price to do 3 inches is 2K Fred

I wonder what would happen if a person had a bus ready to be foamed and drove it over to where the crew was foaming a house and just brought up the subject over a beer at the end of the day lol.

I have no idea if the price I was quoted is any good or not.  I never checked around as I wasn't ready to actually buy.

I only asked these guys because they insulated my house.  I only had a small area of the house spray foamed and they charged me the $400 minimum.  If I had been on the ball I probably could have had some spray foam put in the bus with the rest of my $400.

You can purchase foam kits that you spray yourself, somewhere around $2.00 per board foot, generally the largest you can get is 550-600 bf and will cost $750-1300...depending.

I did the do it your self kit. I think it was the 550-600 bf. I would have to say I was pretty happy with it. I got about a 1/3 of the bus done. Price was in the $600.00 range.

How are they defining a board foot?  1" thick for a square foot just like lumber?

Cody ya need to bring up the subject during lunch, and that there will be COLD BEER at the end of the day. That way they can hop on it before cleaning up the equipment!

(then you get to spend the rest of the afternoon icing down the beer and final prep work before they start spraying! )

This is sort of on topic...

My new to me Prevost (I still need to compose a post about the new bus) has spray foam on the inside AND on the outside.  The entire undercarriage is spray foamed.  The foam underneath is not bad as you cannot see it without crawling under the bus, but inside the wheel wells the foam is peeling/chipping/degrading and looks bad.  In addition, the previous owner had a flat on the driver's tag and did some damage to that area - the slinging tread knocked off a large portion of the foam.  I picked at some of the foam in that area and found it was pretty easy to remove. My question is, what is the downside to removing all of the foam from the wheel wells?  If I remove it, should I replace it with paint, undercoating, Rhino Liner, or something else?  By the way, the PO said the flat did all of this damage, but if you look down the side of the bus you can see where he (or someone else) scraped up against something.



In addition to the fender flare, he ripped the grill off of the vent hole for the generator radiator.



Here is one more to hold everyone until I compose my "I just bought another bus" post.

Brian I wouldn't remove the foam.   My Prevost has the same sprayed foam.  I have touched up the missing "rock and debris hits" foam with the touch up expandable foam (spray can) that  you get at HD or Lowes.

It really does protect the interior of the wheel well, and insulates the inside of the bus from road noise.

Best prices are at trailer dealers like Great Dane,Fruehaul,Wabash,Strick along with other refer trailer dealers and a plus is they know what they are doing 


good luck

Spraying foam is one of those jobs I'll leave to the professionals.  I had 2.25" sprayed into my bus and it's the best thing I had done.  One it really smells (if it is the industrial grade stuff).  And it sticks to just about anything, so forget reusing your clothes again.  Then grinding it down to the surface again-lots of mess also. 
When mine was done, the crew of two got to my bus at 8pm and worked all night since it was cooler.  Were done at 6am with the bus cleaned up.  Was one of the best $1650.00 I spent, and will have my truck done that way again.  Good Luck, TomC

I chose a different method

I used Rmax ->> http://www.rmaxinc.com/wall-r-matte-plus3.asp ".......R-Matte Plus-3 is a rigid foam plastic thermal insulation board composed of environmentally sound, closed cell, polyisocyanurate foam bonded to a durable white-matte (non-glare) aluminum facer and a reflective reinforced aluminum facer. This product is suitable for use in wall sheathing applications in new residential, commercial and agricultural buildings and for thermal retrofit construction to existing buildings. R-Matte Plus-3 is ideal for use in both frame and masonry construction. R-Matte Plus-3 is available in ½", 5/8" and ¾" thicknesses, as well as, several different lengths....."  Reflective foil one one side - non-glare alum on the other side

I just keep ALL THE DOOR AND WINDOWS OPEN - and used SOLVENT based contact cement - with a roller I just applied cement to the roof and to aluminum surface of the foam - I used muliple smaller pieces to make it easier - wait 60 second - then just TOUCHED to two glued surfaces together - tap them with a mallet and a small 2 x 4 - You would need a stick of dynamite to get them down

I framed my ceiling with 2 x 3 and left chanels for my "H" pattern "DUCTED A/C VENTS"  - have pictures if you need to see what I did  - I used multiple layers of foam to a total of 2.5" in most areas - I used the silver A/C duct tape on the seams (just to be sure ??)

The results were absolutely amazing - My RTS with it's huge windows (they are tinted) will HOLD TEMP a long long time - It's like driving in a thermos bottle

JUST MY WAY -
