Has anyone specified or used this product before? I don't have any experience with it, so I couldn't answer her inquiry. Ron Geren, FCSI, AIA, CCS, CCCA, SCIP www.specsandcodes.com Jerome J.

I wonder if the concept is Similar to Privacy Glass? http://www.innovativeglasscorp.com/lc-privacy Ronald L.

However, it appears they incorporate the Suntuitive product in their "SolarSmart" product, so they do have a thermochromic product.

There common room in the southwest corner of the building with tall glass and the owner wanted to try it out. Frankly, nobody has paid much attention to it since it was installed, but having been in that room, it did help reduce the heat gain. Russ Hinkle Jerome J.

The coating darkens as it absorbs heat from the sun. It lightens as it cools. It isn't in the category of Privacy Glass. Even at its darkest state it will not provide full privacy.

We are now repeating these buildings at multiple sites and have asked for the cost breakout, just yesterday in fact. It lived up to my expectations and I don't believe the additional cost was unreasonable (we'll know shortly). Interestingly enough I don't believe it was factored into the energy modeling for LEED.

It is not going to be a LEED project. Of course in SFL there are approvals that must be obtained for use in a hurricane zone.

They likened it to eyeglasses that change tint when exposed to sunlight. Both heat and light affect the tint, so the tint is less in winter than summer.
