Anlin Geometric Windows – No Longer Offered at Custom Exteriors

At Custom Exteriors, we once carried Anlin Geometric Windows as part of our vinyl window selection. While they were a popular choice for homeowners looking to add unique shapes and architectural flair to their homes, we have since transitioned away from vinyl products. Today, we focus exclusively on fiberglass windows, which provide superior performance, durability, and long-term value for East Bay homes.

Why We No Longer Offer Vinyl Geometric Windows
Vinyl geometric windows, including those from Anlin, delivered flexibility in design and affordability. However, after years of installation and service in the East Bay, we found that vinyl simply doesn’t hold up as well as other materials. In our region’s climate—ranging from hot summers in Pleasanton and Livermore to damp, foggy mornings in Berkeley and Oakland—vinyl is prone to warping, fading, and losing its structural integrity.

The Benefits of Fiberglass Geometric Windows

We now recommend fiberglass geometric windows, which outperform vinyl in every meaningful way while offering the same custom shapes homeowners love.

Unlike vinyl, fiberglass maintains its strength and stability across large or uniquely angled openings, allowing homeowners to enjoy dramatic designs without worrying about warping or sagging over time.

Fiberglass special shaped windows give you the freedom to design bold architectural details while also benefiting from superior energy efficiency, lasting durability, and low maintenance.

Durability & Strength – Fiberglass is 8x stronger than vinyl, which allows for larger custom shapes without risk of bowing, cracking, or sagging.
Design Flexibility – Choose from specialty shapes like arches, octagons, circles, triangles, and more to add architectural detail to your East Bay home.
Energy Efficiency – Fiberglass frames maintain tight seals and resist expansion or contraction, keeping your home comfortable in every season.
Low Maintenance – No peeling, swelling, or fading—fiberglass retains its look and performance for decades with minimal care.
Timeless Beauty – Slimmer frames mean more glass and more natural light, enhancing views while creating a custom look that elevates curb appeal.

A Better Long-Term Investment

At Custom Exteriors, we understand that unique architectural windows are a big part of what makes a home feel truly special. That’s why we now recommend Infinity from Marvin® Special Shaped Windows. This product line combines stunning design with unmatched performance.

"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."
