I havent heard back re pricing either, but i did get told something very interesting regarding this glass, and why the cost is huge.

It is used in some high rise office buildings, and tourist type high rises for its non glare properties etc.

Theres no use having the worlds best view if u cant see thru the glass without having to hold your hand up to your forehead to see thru the glare.

The cost for the very thick panels used in high rise buildings must be crazy $$.
