What are the benefits of Infinity from Marvin sliding windows?

Infinity from Marvin sliding windows feature Ultrex® fiberglass frames, smooth gliding operation, and narrow sightlines for wide, unobstructed views. They offer excellent energy efficiency, long-lasting durability, and low-maintenance performance, making them ideal for homeowners in the East Bay and San Francisco Bay Area.

Why is Ultrex fiberglass better than vinyl or aluminum for sliding windows?

Ultrex fiberglass is up to eight times stronger than vinyl and more stable than aluminum. It resists warping, expanding, contracting, and fading, ensuring sliding windows operate smoothly and maintain their shape over time. This makes Ultrex a superior material for high-performance sliding windows.

Are Infinity sliding windows energy efficient?

Yes. Infinity sliding windows include high-performance glass options, advanced weatherstripping, and rigid Ultrex frames that help reduce drafts and heat transfer. These features contribute to improved comfort and potential energy savings for Bay Area homeowners.

Do Infinity from Marvin sliding windows require much maintenance?

No. Infinity sliding windows are designed for low-maintenance living. The Ultrex finish is mechanically bonded and fade-resistant, meaning it will not chip, peel, or require repainting. Routine cleaning is all that is needed to keep them looking great.

Can Infinity sliding windows be customized?

Yes. Infinity sliding windows offer multiple interior and exterior finishes, hardware options, grille patterns, and high-performance glass choices. This allows homeowners to match their windows to both traditional and contemporary architectural styles.

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

Brian I.

"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."
