Anybody have any experience with durability of Elgin-Butler glazed bricks in
severe weather areas (I'm thinking Chicago, Michigan, NY, etc)?  They have
submitted excellent test results (including 650 freeze-thaw cycles without
failure, and very good IRA and COS numbers) for one of their glazed brick,
but would REALLY like to hear from (or of) somebody who's got this brick
installed in the weather.  We understand (from the brick salesman) it's used
in Chicagoland subway stations, but whether this is indoors or out is
unclear.

Thanks.

Ralph
