Why
Choose Fiberglass
Pultruded fiberglass is engineered material created through a process where strands of glass and glass matting are pulled through heated dies. The result: lineals customized to specific window component requirements with exceptional durability and performance. Preferred for durability, versatility, and superior engineering.
Key Considerations
Fiberglass is incredibly strong and resistant to warping, rotting, and swelling, making it ideal for withstanding harsh weather conditions and ensuring longevity.
