Fiberglass and vinyl frame are two of the most popular options for replacement windows, but before you make a decision, it’s important to understand some key differences that make one a better choice than the other:
Strength and durability
Fiberglass windows are significantly stronger than vinyl frame windows, which makes them capable of withstanding extreme weather conditions and less likely to warp or break over time.
Resistance to expansion and contraction
Unlike vinyl frames, fiberglass windows don’t expand or contract with temperature changes. This stability ensures a better seal, reducing the risk of drafts or energy loss over time. It also means less maintenance and fewer issues related to frame deformation.
Thinner frames
Fiberglass windows feature thinner frame profiles compared to vinyl. This design allows for a larger glass area, offering better views and letting more natural light into your home.
No weep holes
Fiberglass windows often come with sloped sills, which naturally direct water away from the windows without the need for weep holes. This design reduces maintenance and creates a cleaner, more seamless look.
