Once upon a time, the great silver screen for windows was made of steel. It was a tough-and-rugged performer. Then in the 1940s, the new silver screen became aluminum. Lighter in weight and cheaper, it took over quickly. But both aluminum and steel soon gave way to a new kid on the block. In the '60s high-tech fiberglass debuted. Even lighter in weight and lower in cost, it was an almost invisible small black mesh screen that didn't dent, rust or tear. In no time at all, the great silver screen went dark. Today, border-to-border and coast-to-coast, fiberglass screening is easier than most. So if you're still getting bugged because of holes in your screens that you've put off replacing because they're aluminum or steel, it's time to change to fiberglass. And that's the On The House tip for today.
