Was on a construction site looking for information on the best glues to use to attach polyiso to polyiso and to attach polyiso to wooden studs and furring strips. And came across information that explained to me why I had encountered so many problems in the past trying to glue Mylar surfaces.
The explanation is simple: Mylar is impermeable and so nearly all glues that we generally think of trying dry far too slowly on it. I didn't find a specific glue recommendation for gluing Mylar to Mylar or Mylar to any other surface other than that the glue needs to be extremely fast drying and is unlikely to be something we will find in a tube or cartridge. Maybe that will help someone in their quest. I am attempting this summer and fall to create a permanently installed, livable tiny-home modified hexayurt from 4"-thick polyiso. And so, rather than tape or velcro the beveled edges, am looking for an extremely strong permanent adhesive. Still researching what might be best. A test I did in 2011 of asphalt emulsion (spreadable roofing tar-like compound) has held through heat and cold on both polyiso and xps. But it's not a pretty looking solution. Polyiso supposedly is compatible with most construction adhesives. Not to take this thread too far afield, but am facing a lot of other little challenges when trying to create a "permanent" hexayurt of polyiso. Issues like moisture barriers in and out, moisture venting, window flashing, solid door framing, etc. (My salvage-yard polyiso is not foil-faced, but rather, paper faced and so provides no moisture barrier either inside or outside.)
