ponents affect the overall efficiency of insulated glass, and its overall cost. These are:1. The Glass Used. Insulated panes may use coated or uncoated glass. Coated glass works better because a coating of thin metallic oxide is applied on it which decreases the amount of heat that passes through the panes. Coated glass is also called "Low e", meaning low emissivity. 2. The Gas Used between Panes. For the best efficiency possible, Argon and Krypton are the choice gases for insulated glass because they are the most effective in slowing down the movement of heat through the air space. These gases are also the most expensive. In the more affordable insulated glass windows, dehydrated air is used.3. The Type of Spacing Material. The spacing material used is also critical in producing efficient windows. Many companies use aluminum, which is actually a poor choice considering the heat-conducting properties of this material. Lately however, manufacturers have been trying out more suitable spacing materials such as stainless steel or a combination of composite metal and rubber.4. The Window Frame Material. Even if it has nothing to do with the glass at all, the material used for framing the window is also an important factor to consider. Solid metal frames, although commonly used, are not quite a good fit for this purpose as they draw the heat out of the house, canceling out some of the effect of the insulated windows. Better and newer framing materials are wood, vinyl-clad wood, or metal with insulators between the inside and outside components.Now let's go back to the original problem of foggy windows. Sad to say, fogged up or cloudy insulated windows cannot be repaired. As window seal failure and moisture entering the glass panes is an irreversible process, there are no window repair options and the only question for you is if you can just have the glass panel replaced or the whole window (hopefully not).The typical rule of thum up homes at today's bargain prices, which is also helping housing markets.I realize a few positive articles do not mean we are finally at the "bottom." No one can time the exact bottom -- never have, never will. However, I will say this:IF YOU HAVE BEEN THINKING ABOUT BUYING A HOME, THEN BUY A HOME NOW!!!Sorry for yelling, but it's time to get off the fence. If you have been wishy-washy about taking advantage of today's low prices, now is the time to stop being wishy-washy. If you want to buy before the rebound, you should do it now. Because the rebound is coming. We might not be at the bottom, but you can almost see it coming. There are three reasons to think a rebound is near:1. If the markets that first got hit with foreclosures are starting to rebound, you can bet the other markets will follow. It happened with the crash that way, and it will happen with the upturn. And some of the worst neighborhoods in America in terms of foreclosure are starting to show revitalization. From the USA Today article:"What I'm seeing is incredible. At ground zero in Florida, my business has tripled overnight," says Suzanne White, an agent at ZipRealty in Tampa. "There isn't grass overgrown and mosquitoes all around in these neighborhoods anymore. First-time home buyers are saying rates are so low they can pay less than rent. The bank-owned properties are getting multiple offers and selling higher than asking price."Which leads us to Reason No. 2...2. If there are multiple offers and bidding wars, you can bet that prices will start to rise. Bidding wars normally mean more buyers than sellers are out there -- which isn't the case yet -- but competition for the great deals on homes is going to start driving up prices. That, in turn, will bring out even more buyers. For some reason, home buyers buy when everyone else is buying. And when that happens, it will accelerate the price increases.Which is also why Reason No. 3 is so important...3. In this day and age, public sentiment and media hype drive markets. We saw it with the dot.com bubble. We saw it last summer with the ridiculous run-up in oil prices. We saw it with the massive sell-off of financial stocks and even with the huge bounce in the price of gold. With the Internet and 24-hour news channels hungry for se
