French Door FAQs
What makes Infinity® from Marvin® French doors different from vinyl patio doors?
Infintity from Marvin French doors are made with Ultrex® fiberglass, which is significantly stronger and more durable than vinyl. Unlike vinyl, fiberglass resists warping, cracking, and fading in the Tri-Valley’s hot summers and cooler Bay Area winters. It expands and contracts less with temperature changes, helping maintain a tighter seal, smoother operation, and better long-term energy efficiency.
Are Infinity® French doors energy efficient for Bay Area Homes?
Yes, Infinity® French doors are designed with advanced Low-E glass options that help regulate indoor temperatures year-round. In Pleasanton and throughout the Tri-Valley area, this means reducing heat gain during warm summer months while keeping your home comfortable during cooler seasons. The durable fiberglass frame also helps prevent air leaks and drafts, contributing to lower energy bills.
Can Infinity® French doors be customized to match my home's style?
Absolutely. Infinity® French doors are available in inswing and outswing configurations, multiple finish colors, grille patterns, and hardware options. Whether you have a traditional home in San Ramon or a more contemporary property in Dublin or Livermore, Custom Exteriors can help you design a door that complements your architecture while maximizing light and views.
