Milgard Fiberglass Windows
Advantages of Fiberglass Frames
- Traditional wood profile
- Extremely strong—can hold large expanses of glass
- Low maintenance
Milgard’s fiberglass is produced using a process called pultrusion. Glass rovings and mats are pulled at tremendous forces through a resin bath and a series of dies. These materials combine and catalyze to provide tensile and torsion strength. All final products undergo extensive testing for quality and consistency.
