Anlin Slider Windows – No Longer Offered at Custom Exteriors

At Custom Exteriors, we used to carry Anlin Slider Windows as part of our vinyl window selection. While Anlin was a trusted name in vinyl windows, we’ve since shifted our focus entirely to fiberglass windows because they provide longer-lasting performance, improved energy efficiency, and better value for East Bay homeowners.

Why Fiberglass Slider Windows Are the Better Choice

We now recommend fiberglass slider windows, such as Infinity from Marvin, because they outperform vinyl in every category that matters most to East Bay homeowners.

Unlike vinyl, fiberglass slider windows are specifically engineered to handle the wide temperature swings and diverse microclimates of the Bay Area.

Whether it’s the intense summer heat in Dublin and Livermore, the coastal moisture in Alameda and Berkeley, or the crisp evening breezes in Walnut Creek, fiberglass resists expanding, contracting, and deteriorating over time. This means your windows maintain their shape, seal, and smooth operation for decades—something vinyl simply can’t promise.
‍

Durability & Strength – Fiberglass is 8x stronger than vinyl, which means your slider windows will glide smoothly for decades without bending or sagging.
Energy Efficiency – Engineered to withstand extreme temperatures and maintain a tight seal, keeping your home comfortable year-round.
Smooth Operation – High-quality rollers and durable hardware ensure easy, everyday use, even in high-traffic spaces like patios or kitchens.
Low Maintenance – No warping, swelling, or cracking—just windows that continue to perform with minimal upkeep.
Modern Aesthetic – Slimmer frames allow for larger glass panels, giving you bigger views and more natural light.

A Better Investment for East Bay Homes

At Custom Exteriors, we love helping homeowners choose the right windows for their home, budget, and lifestyle. While vinyl slider windows once met the needs of many households, fiberglass has proven to be the smarter, long-term investment.

"Loved working with Custom Exteriors. Very responsive to inquiries. Precise in their measurements, estimate and timeframe for completion. Highly recommend them."

"Custom Exteriors provided a great product and good service in replacing 2 sliding glass doors and 2 other windows in my townhouse. One was a custom window that required extra work in refitting the plantation shutters to the new window. Although there were some bumps along the way, Jeff and his foreman Ryan excelled at follow up. I would recommend Custom Exteriors."

"Kevin one of the owners of Custom Exteriors contacted me the following day and immediately tried to make things right. The first thing, I was impressed about was he took my call without hesitation. Many medium sized business will bounce me around to different people before finally being able to talk to the owner. He was an attentive listener and took to the time understand my needs and wants in an exterior entry door.His communication was top notch, sending me estimates the same day or the following day. He gave me choices in fiberglass doors: ProVia and Therma-Tru, hardware: Trilennium vs Emtek, and single point vs multiple point locks. I just ordered a ProVia doors through Kevin. This surprised both to my husband and me. Before contacting Custom Exteriors, we thought we were going to get a Therma-Tru door, but that totally changed once we the information we needed from Kevin. I get the sense that he truly wants to give customers options and information, but respects the customer's final decision. There is not high pressure sale pitch. Kevin wants customers to be informed and happy with the end product."
