there are only a couple manufacturers out there i know of - try running a search on saint-gobain glass. i'm using a good amount on a showroom space - your client better have deep pockets...

- from an earlier thread.

thanks guys...
garpike that was worth it just for the clapper joke.

suspended particle display or spd, it becomes opaque but does not block out the sun
and
fyi: when the electric current is passed the glass becomes clear and when the current is off the glass becomes opaque.

for sun blocking, there is a product out there by 3M but last i checked they were in the process of coming up with a new generation but that was about a year ago. they may have done it by now!

Many of us know how the liquid crystal works: when there is a current, or it is "on", the little crystal guys line up head to toe in a neat organization, therefore allowing the most light through. This gives the appearance that the glass is clear. When there is no current, or it is "off", the crystals beome disorganized. Light cannot easily pass through. The glass appears cloudy.

So there's a mini-debate a brewin': Can't we all say the glass is "on" when it is "off", or do we have to be technically correct? Being a nerd myself, I lean toward the technically-correct know-it-all version, but it may be easier to just accept that people will say the glass is "on" when it is cloudy. It may keep baby Jesus from crying.

Sorry. It's Friday night, and I am nerding-out in front of my computer... at work.

on the same subject (sort of), does anyone else think that the LA prada store is less than spectacular???

Specifically, what is rubbing you the wrong way? I like the store. But I didn't write home about it...
