How are Fiberglass Windows Made?

The fiberglass used in windows is different from the material used for boats, pools, or storage tanks. It is made through one of two processes – pultrusion or extrusion – in which continuous strands of glass get pulled or pushed through thermoset resin and passed through a heated die to create lengths of fiberglass. Then manufacturers fabricate the lengths into fiberglass window components.

Are Fiberglass Windows Energy Efficient?

They are ideal for windows with multiple panes of glass. This means the seals on fiberglass windows last longer and will not cause unwanted air and moisture leaks.

How Long Will Fiberglass Windows Last?

Most of these products can last for 30 years or more as long as homeowners perform proper maintenance. Some top quality products even have a life expectancy of 50 years.

What is the Maintenance for Fiberglass Windows?

These products require very little maintenance. Power washers and harsh, abrasive chemicals can damage the frames. Instead, homeowners should wash these windows with mild detergent and water periodically to gently remove dirt and debris.

Do I Still Have Style and Color Options?

Yes. Fiberglass windows are highly versatile. Manufacturers can create bay, bow, sliding, double hung, single hung, casement, picture, and awning fiberglass windows. Also, homeowners can choose a specific color or finish from the factory or choose to paint fiberglass windows any color they choose.

How Much do Fiberglass Windows Cost?
