not interested in Cuben but could easily get interested in a nylon and foam version. Nice thing is I don't have to worry about what happens in a 4 day rain. ;-)
Well, I think I have solved the question about IX composition. Following the greenhouses literature he are differents permeability of defferents materials to the FIR (Far InfraRed):
Film PE -> 80%
Film EVA 18% -> 38%
Film Polyester -> 27%
So, If the core of insultex is PE the polyester scrims can be what Reflect IR.... In fact there are some Polyester-poliamide geo-textil fabric used to cover the plants ground that, in fact, reflect the IR really well.
There are some frabrics being used in aircraft wings that is really lightweigth polyester but.... if you begin to add costs, Is cheaper to buy the Insultex directly. But... What about a (Evazote EV30 18% VA for example) EVA foam 0,5 mm With polyester scrims.... Can be interesting ....
Well, Only to make the point about this matter because finally I'll go with IX Easier - Cheaper.... Much better for me, at least.
Also...would using 1/8 inch work with 2 layers, or would it be better to use 3 layers due to have more air gaps for insulation? It just seems the 1/8 is easier to find, that is why I ask, I'm still looking for 1/32 though.
