Alejandro. Thank you!, *exactly the answers i was looking for*, so I need roughly 40 Poly iso panals. R-tech is not Polyiso, hence the lower price tag, and also it's more likely to breakdown and it's not as weather resistant.
I am going to make a couple h12's and my h13, as well as as many little h5's as I can carry. and yeah I'm building everything in Tahoe, and driving to playa from there. I've been playing with adhesives and found the perfect roofing adhesive for the joint tape as well. all edges will be sealed pre-playa. -X PICS TO COME!
