Opinions regarding European hollow insulating clay bricks
I just stumbled upon a type of clay brick that is apparently gaining popularity in Europe but seems totally unknown here in the USA. Example: http://www.juwoporoton.com/products/
The bricks are hollow, full of tiny vertical cavities that trap air and, apparently in conjunction with the air-entrained brick itself, claim to render the masonry material capable of being an insulator. Some types of brick have mineral wool stuffed in the cavities. R-values appear to be roughly 1.7-2.2/inch. The exterior structural bricks are very thick; 12-18 inches. The whole-wall R-values aren't amazing, but top out at 40 for the really thick bricks. Whole-wall R-40 certainly isn't bad by any stretch of the imagination. And the large and interlocking characteristics of the bricks seem to lend themselves to rapid construction. They look to be fairly lightweight for their size, but have been tested to withstand small arms fire.
Does anybody stateside have any experience with these types of bricks? Any opinions? Any clue what they cost over in Europe? I haven't been able to find any pricing online.
