Home Improvement Tips

Anyway you hear a home remodeling idiom with the word smart in it, you know you’re about to learn the latest in new technology. They are in fact becoming increasingly popular, especially amongst commercial development, which means that soon they’ll be showing up in the private sector as well. When a product is smart it simply means it is planned with an auto-intelligence capable of operating a single task. And the same goes for smart glass: instead of relying on window treatments to block the light and control the sun’s solar penetration.

How does Work? 
Often referred to as switchable glass, these window panes dim and brighten at will. When you want sun to shine through your windows, simply flip a switch to turn off the tint. You want to open a room, another flip and the windows will blur, become opaque, or slowly darken. Though they all perform the same task there are several types of smart glass out on the market. One of the original forms is photo chromic technology which doesn’t require any manual operation. Similar to sunglasses, these panes immediately tint when the sun hits, which is efficient since they don’t call for any electricity or hands-on direction (there’s also thermo tropic panes which dim according to heat levels). However, if you want a little sun to brighten a space in the home, you’re out of luck. Plus, during winter, when you want some solar heat gain, these panes won’t help you out.

In the last few years there have been several improvements in switchable glass :

• Suspended Particle Devices: A conductive glaze covers the two panes while in between countless particles lay suspended in a liquid film. When denied electricity, these free floating elements block out the light, darken a room, and remain opaque until the switch flips. Then, when the circuit is complete, they quickly line up and allow light to pass.
• Liquid Crystals: The same stuff found in your digital clocks and DVD displays can also be put in windowpanes. Working similarly to SPD technology, these products are black and white: turn it on, they line up to permit light; turn it off, you’re in the dark again.
• Electrochromic Glass: These panes work in the opposite manner: when a current is supplied, they darken and when electricity is withheld they become clear. Another unique aspect of these particular products is that they aren’t so black and white. Instead they are able to create varying levels of light penetration, allowing you to have total management of the sun’s power. Sometimes it takes several minutes to change shades and typically electro chromic glass works from the outside to the center, but it also doesn’t require a constant stream of electricity: once the initial tint is achieved, no more power is needed.

If window treatments achieve pretty much the same thing, you may be wondering about the point of these inventions. Well, first off, they’re incredibly energy-efficient. Unlike traditional drapes, blinds, and curtains that contain slats and openings, smart glass won’t allow any heat gain at all. Plus, they don’t need cleaning and they won’t fade in the sun like cloth and plastic. Also, they only require a small amount of energy to sustain their use (powering several windows at once uses less electricity than a single light bulb) and electro chromic glass hardly needs any electricity at all. Plus, like any technology that may appear over-the-top at first, it’ll probably come to replace every previous invention (for instance, when was the last time you used your VCR or tape deck?).
