Today's homeowners want more than a room with a view. Some want a view from every room. It might not be practical in each case, but bringing the outdoors inside with a beautiful glass wall is becoming a very popular home-updating choice. For modern and traditional homes, technology is making large windows more practical. Nearly all windows installed in new homes have invisible coatings that block heat and keep ultraviolet rays from fading furniture. Many new windows have triple panes filled with argon or krypton gas sandwiched in them for insulation. A titanium dioxide coating sold by Anderson Windows sheds dirt and virtually eliminates water spots. Some windows can tint and untint with the push of a button. If you want window shades, companies such as Lutron Electronics sell shades that can be controlled with an iPhone app. There are a few downsides. First, no window will be as energy efficient as a wall packed with insulation. Then there is the bird problem. Anywhere from 100 million to 1 billion birds are killed in window collisions every year, according to the U.S. Fish and Wildlife service.
