Yeah, 36 feet is about 12 yards.
I will go look for marine headliner at some of the upholstry shops, and insulation foam.
How luch did it cost by the way? (for the headliner and foam)
Check out these folks
for marine vinyl. They do boats and RV's as well as sell the insulation seperately. You can get the headliner material from them for substantially cheaper than the Trilliam folks and they seem like good people to deal with. I, on the other hand, will continue to buy from Joe because he's treated me well over the years and I prefer to buy local, even if it does cost me a bit extra.
I think Joe at Team Trillium
quoted me on the order of $5.00/foot for insulation and about $12.00 a foot for the headliner but that's from memory. He also gave me substantial tips and instruction on how exactly to apply the material and gave me some glue as well. I'm always happy to pay a little more for good advice. Having said that, the folks at Aqualine also gave good (but different) advice.
One common thread which is mirrored in various other forums, is that you can't go and use regular off the shelf contact adhesive. You have to go for the industrial stuff. ie: Even 3M's Spray 90 won't adhere well with material on the roof of your trailer with the sun beating down on the other side of it.
I don't want to do this job again so I'm going to follow the advice.
The folks at Aqualine Vinyl will tell you that and so will Joe. So whoever you buy from, make sure you also buy some glue.
