Fiberglass Windows


Fiberglass itself is nothing new. It's been floating boats and adding strength to ladders for years. But until recently, the complex profiles required for window designs such as bay windows have been impossible to attain with fiberglass. Fiberglass replacement windows are relatively new and not yet widely available. They have the highest R-values of all frames; thus they are excellent for insulating and, like vinyl, will not warp, shrink, swell, rot, or corrode. Fiberglass replacement window frames can be made in a variety of colors and can hold large expanses of glass.
	Technology faced this challenge and engineered a window and door system that's impervious to water, cold, heat, insects, salt air and ultraviolet rays. The end result: efficient fiberglass windows and doors that maintain their beauty in every season, in any climate. Fiberglass replacement windows can also be painted, which provides some flexibility if you decide to change the color of your window frames in the future. However, windows made of fiberglass will be more expensive than replacement windows make of aluminum or vinyl.
