At Custom Exteriors, we previously carried Anlin Picture Windows as part of our vinyl window offerings. While Anlin was a popular brand for vinyl replacement windows, we’ve made the decision to focus exclusively on fiberglass windows for our East Bay homeowners.

Vinyl windows, including Anlin Picture Windows, offered affordability and decent performance for many homeowners. However, over time we found that vinyl simply doesn’t hold up as well in the East Bay’s unique climate. Hot summers in Pleasanton and Livermore, cooler damp winters in Oakland and Berkeley, and everyday wear can cause vinyl to warp, fade, or become brittle. These issues can lead to air leaks, higher energy bills, and increased maintenance costs.

Why We Recommend Fiberglass Picture Windows Instead

Fiberglass has proven to be the best long-term choice for homeowners looking for large, stationary picture windows that highlight views and bring in natural light. Compared to vinyl, fiberglass picture windows offer:
‍Strength and Stability – Fiberglass frames are 8x stronger than vinyl, which means your windows won’t warp or shift, even on extra-large openings.
‍Energy Efficiency – Tight seals and insulated glass keep your home comfortable year-round while lowering energy costs.
‍Low Maintenance – No peeling, swelling, or cracking. Fiberglass requires virtually no upkeep beyond simple cleaning.
‍Timeless Beauty – Slimmer frames allow for more glass and bigger views of the Bay Area hills, vineyards, and cityscapes.
‍Better Value – Fiberglass consistently outperforms vinyl in resale value and long-term durability, making it the smarter investment.
