A guide to fiberglass windows and fiberglass replacement windows
Manufacturers claim that fiberglass windows offer the best insulation of any type of frame on the market. Fiberglass is an extremely strong and durable composite material made up of reinforced glass fibers and resin. A relative newcomer to the home improvement market, fiberglass has become increasingly popular over the past 10 years or so and continues to command a growing market share.
Advantages of Fiberglass House Windows
Fiberglass has numerous inherent properties that make it an excellent material for window frames. It has excellent dimensional stability, doesn't conduct much heat and its thermal expansion coefficient is nearly identical to that of glass. This creates an extra level of stability that no other material can offer, and allows these frames to perform well in extreme conditions.
Fiberglass house windows also excel at warding off condensation, helping you maintain optimal humidity levels. Their tight seals resist leaks and draughts, and they will never rot, warp or lose their shape. If you're wondering about the strength of fiberglass windows versus vinyl windows, you should know that fiberglass is almost 10 times stronger (although it is also more expensive).
Finally, for the ecologically conscious consumer, fiberglass house windows are recyclable. They do not have nearly the environmental impact of, say, aluminum windows.
The Flexibility of Fiberglass Replacement Windows
One other key advantage of fiberglass is that it can be fashioned into customized shapes quickly and inexpensively. Thus, if you'd like to build elaborate fiberglass bow windows, you can do it without spending a great deal of money. Of course, it also comes in standard shapes and sizes, so if you just want plain, simple fiberglass casement windows or for double-hung windows, you can buy ready-made frames.
This flexibility is one of the reasons many homeowners rate the aesthetic value of fiberglass very highly, but it is generally considered more inherently pleasing to the eye than the vast majority of other frame materials. It is one of the strongest, most sustainable and long-lasting options available to homeowners looking to buy replacement windows. If your budget allows for this premium product, chances are very good you will never regret your decision to buy fiberglass window frames.
