Heat loss in buildings is largely attributed to poorly performing windows and walls. Fiberglass windows, doors, and cladding support systems contribute to superior building envelope thermal performance. Presented here is the impact of windows on building performance, the characteristics that make fiberglass windows thermally efficient, and how fiberglass cladding support systems mitigate thermal bridging, improving energy efficiency.

Upon completion of this course, the Learner should be able to:

• Compare the effect that increasing the R-value of each element of the building envelope—the roof, walls, and windows—has on the increase in the overall building energy performance.
• Discuss how the condensation resistance, strength and durability, low coefficient of thermal expansion and contraction, and enhanced thermal performance of fiberglass windows contribute to improved building envelope thermal performance and make fiberglass an ideal window frame material.
• Explain how a fiberglass cladding support system mitigates thermal bridging and helps meet stringent code performance requirements.
• Use project examples to illustrate how fiberglass windows can achieve a multitude of design and performance goals.
