Under trailer insulation spray

[Brian B-P]

I looked at large fifth-wheel travel trailers almost a decade ago that had this type of foam insulation; however, it is still not common here and probably very uncommon in less northern areas.

I doubt the foam on an Escape would weigh 200 pounds, as it would need to be a foot thick... but I don't know the actual weight.


Could a moderator or administrator move this topic to a more suitable location in the forum?

I think when it was first offered, Reace guesstimated the spray foam insulation added 70 pounds or so... That might have included the heat pads.

Reading all of these posts just gives us a better excuse to head to Chilliwack this fall. Then if we mess up the order, there is no one to blame but ourselves.

70 lbs is probably correct, I just can't remember everything I read….but I try!

camping, but it is also incredibly effective in Hot Weather. For me , both insulation packages are on my working build sheet for a 19ft Escape. Also the thermal window/tint helps. Remember, your home away from home will quiet also.

One of my main concerns on the Escape trailer was how well the under trailer foam insulation would hold up to road debris, gravel, etc. We were at ETI and Reace took me out back to show me a trailer that had this option. I was happy to see that the insulation was much harder than I had anticipated. I don't see this being a problem or concern anymore. Loren

Earlier in this thread someone else said 200 lbs.......

does anyone know an accurate number?

Would be nice to have.... but I am concerned about the weight....

We're Californians too and have camped down to 26 or so at night in our 19. Wasn't a problem and I'm passing on this on our 21. No plans to do any serious cold weather camping, that's a good time to stay home and go to the beach!

Yes, a value of 200 pounds was given, but then it was explained why this would not be likely:

... and then the number from Reace was provided:

Is that close enough?

It seems similar to that Great Stuff crack filler you can buy in a can at Lowe's or Home Depot.

It would surprise me if the whole amount on our 21 weighs more than 20 pounds.

The 2 part spray foam comes in various densities, but most of the ones that would be appropriate for the trailer would mostly like weight between 1.75 - 2.5# per cubic foot fully expanded. So if someone knows the approximate average thickness the approximate total weight could be calculated fairly easily calculated

(Makes my skin crawl remembering spraying this stuff over my head in my attic )

We do not have the foam insulation. As you indicated, it isn't very heavy. As hard working Municipal employees, my mechanic once emptied an entire can onto a piece of cardboard which he then carved into a turtle. It became the shop mascot and hung around the shop for years. Your tax dollar at work. It wasn't very heavy.

Checking under our 21', I estimate the coverage at 3 inches times 5 feet times 15 feet.

75 s.f. times .25 f thickness, gives about 19 cubic feet.

Using the number given of about 2# per cubic feet, the estimate becomes about 38 pounds.

I guess only the spraying contractor knows for sure.

You should be so lucky! Our hard working Municipal employees only lean on shovels. There ain't a creative gene among the lot of 'em.

Bill, nice job with the math! A long time ago I also heard the 200 lb figure stated, and that was by an employee. I asked Reace directly and was told that the foam insulation weighed about 40 lbs.

As I mentioned before, the 200 pounds is unreasonable. The 80-pound value seemed roughly reasonable to me, but I was guessing a little more length and much more thickness than Bill (and using the same method), so I'm not surprised that the final answer is 40 pounds.

Glad to know it is around 40 lbs.

Awesome.
