The primary difference between Rmax and Thermax is that Rmax is not as strong as Thermax. I built a window box solar air heater last December. The plans called for Thermax. In discussions at a solar heater group at Yahoogroups, the general consensus was that Rmax was OK as a substitute, except that it wasn't quite as strong as the thermax.

I was told by the sales rep that Thermax is being phased out completely...the plant that produced it for the south was shutdown, leaving the northeast the only current place of manufacture. It wasn't what I wanted to hear. But he said the Rmax was a suitable replacement, having the same fire safety and similar R-value. I'll see if more info is available. Hoping to document the entire building process, possibly incorporating it into a project for our local homeschool school on alternative building materials, and also keep a journal of the living experience, as time permits. We'll see how all that goes : ) On Saturday, January 12, 2013 1:52:39 PM UTC-5, Vinay Gupta wrote: This sounds pretty sane.
