Love the look of big, open windows, but don’t love the lack of privacy? Aside from making your private business very public, leaving windows uncovered can absolutely kill your electric bill. That’s because big windows let in light—a lot of it. This can be awesome in the winter, allowing that warming sunlight to generate a little free heat. However, letting all of that sunshine in during those summer months will heat up those same rooms. And having multiple fans, central air and other energy leeches won’t save you from that type of blistering heat! Of course, you don’t have to opt for ugly, dust collecting curtains or even blinds. There are plenty of tinted and patterned glazing available. But why block a great view when you don’t have to? That’s why the Shield House Solutions Ltd. introduces the “Smart Glass” solution. You can not only block out the sun but also have some privacy when needed. This solution is a perfect addition to our burglarproof or bulletproof windows and security doors. Glass can actually be tinted at the touch of a button either be used with bulletproof glazing as “Bullet Active Smart Glass”– after first shot when the bullet hits the glass, the sensors immediately reacts and the clear glass turns into opaque, not leaving the chance for shooter to take next accurate shot.
