For the ones that used spray foam, what brand and how much did you use?

You can use the self spray system. But to do it right you should spray enough that you have to grind it down flat. It is one of the few jobs I contracted out. It is a nasty, messy job left best to the professionals-and I'm really glad I did. Good Luck, TomC

I used a spray foam kit and did it myself. It is a very messy job and I agree with Tom, hire it out.  Don

Name??? -

Do you have a repair facility nearby that works on 18-wheeler trailers, especially reefers?  If so, go by and talk to the service manager and find out who does the spray foam for them.  Then set up an appointment to be there with the prepped coach the same day he's going to be doing trailers.  The pro will have all the necessary tools to do it right the first time, including smoothing it out for you.

This is one part of the conversion project that is well worth contracting out.  Best bang for the buck in the long run.

FWIW & HTH. . .




PS:  Please take a few minutes to update your profile with a signature line that includes at least your first name, home base city/state, make/model of coach and it's powertrain.  That way we can better help you by referring you to relatively local vendors, and you might just find out there are fellow busnuts in your area, too!  Welcome aboard!

Any refrigeration trailer out fit like Great Dane will hot foam it, and hot foam if you are going to use foam is by far the best but if anyone in your family that is chemical sensitive stay away from foam it will cause problems to those people.

You need to seal around the up rights and roof brows if the spray gets behind those it will wave the siding and roof BTDT

good luck

It's definitely a do-it-yourself job and very easy to trim.  No joke; just watch the six youtube videos I posted in Reply # 36 in my "Introducting the Silverliner" bus project thread to see what's involved.  I'd link to it, but I don't know how.

I used two-part foam from Mcmaster-carr http://www.mcmaster.com/#spray-foam-insulation/=krn3n6 the $831 ones, took two to do the whole bus (walls and roof)

For trimming I made this really safe tool (haha) Cheesy that I used with my big Milwaukee angle grinder
It works REALLY well to do the trimming but I have to say at 10,000 RPM it's pretty  ****ing scary....

The latest recommendations I've seen for spray insulation for houses is to use a cold applied spray foam instead of hot applied.  The hot applied foam can shrink as it cools and cures leaving gaps.  The rim joists in my house were spray foamed in 2001 during construction.  Cracks developed in the foam all over.  I had the insulation company come back, but all they did was fill the cracks with a can of spray foam.

The whole reason for using spray foam is that it sticks to the walls making everything tighter and I can tell you it does not squeak. Now use foam blocks cut to size-I can see those squeaking. Good Luck, TomC
