Hi all,

Anyone got these in their house? We're struggling with a decent window-blind option in our kitchen - one ordinary window, and one square bay. I like the idea of remote-controlled frosting/dimming, and I've scouted a few websites. It looks like I can get them for around £1500 + fitting. Anyone got any experience with them, and any company recommendations?

Cheers.

You refer to Smart Glass. There are issues with this I believe as it works the opposite way to what you expect. You expect it to frost up when switched on but it's the other way around. I don't know much about it but came across some on a project where the owner was removing stuff that had failed.

The glass contains particles suspended in a liquid between two panes. It blocks the light when the panel is switched off. Most of the time you're going to want them to let light through which obviously means having it switched on. The issue I believe is like old cathode ray tube screens. If you remember back in the day when a pub might have had MTV running all the time, eventually the MTV logo in the corner would burn into the screen and become visible even when watching another channel - this burn over time from a fixed image being the reason screen savers were invented I believe. My understanding with this Smart Glass is that in the longer term, if you have it switched on more than off the you get a similar burn effect and eventually it will no longer work.

Here ends my limited knowledge on the subject. There are other types of smartglass available that I found on Wikipedia

great - thanks for that. So probably too early in its development to go with it now then.

I don't think it is too early to go for it.

Ferrari had something similar on the 575 Superamerica back in the later 90's / early 00's with its variably tinted roof. Saint-Gobain, who developed the glass in the Ferrari have had this commercially available for buildings for a number of years too.

I've seen it in hotels too, Aloft at Excel in London has it. Seems to work well and I don't think they'd risk it if there were concerns about it being fully developed or not.
