Fiberglass Manufacturing and Window Performance Testing

More mainstream window and door manufacturers are introducing fiberglass profiles to meet the demands of most architects and designers. These profiles are available in various sizes and operations, suitable for almost any project. The energy performance ratings of a fiberglass frame is similar to that of vinyl windows, especially when adding high-performance glass. The fiberglass production process now enables complex profiles required for the look of painted wood windows and many offer wood interiors with the option of a durable exterior, while enhancing the interior with the warmth and beauty of various wood species.

After completion of the course, you will be able to:

  • Discuss the history of fiberglass for fenestration and understand how fiberglass allows for a strong, durable and low maintenance frame type.
  • Explain the fiberglass pultrusion and manufacturing process.
  • Discuss the definition of a window's performance grade (PG) and design pressure (DP) rating and learn how they are related.
  • Observe an AAMA air test is performed for DP ratings.
