Re: Possible alternative to Reflectix?
The attic radiant barrier foil is not much less expensive than Reflectix. And there are places on the boat that may not have the available room for the Volara - in these places Reflectix can be used by itself.
I have used Ethafoam which is closed cell and similar to Volara in price.
The air space is needed in conjunction with the foil barrier to create a radiant barrier.
From the attic foil link:
Then what good is reflectix, when people are putting it behind closed celled foam it is basically only a vapor barrier at that point? I agree for the places where spacing is hard, but for the most part, it seems like they were saying on frugal mariner that it was ok to have it touch the surfaces of reflectix(same as attic liner?)
