At Mainstream Home Improvement, we’re thrilled to introduce Infinity® Windows by Marvin – our top-tier window line that’s transforming residences throughout the Quad Cities. If you’re planning a window upgrade, Infinity® brings together advanced innovation, enduring beauty, and exceptional performance – making it the smart, long-term investment every homeowner can appreciate.
1. Strength and Stability with Ultrex® Fiberglass
Infinity® windows are crafted using Ultrex® fiberglass, a patented composite material that outperforms traditional options like vinyl or wood. It’s stunningly eight times stronger than vinyl, offering a level of rigidity and structural integrity comparable to low-carbon steel. This robust design means slimmer frames, broader views, and windows that retain their shape through Iowa and Illinois weather extremes.
2. Rock-Solid Dimensional Stability
Fiberglass’s natural resistance to expansion and contraction ensures that Infinity® windows maintain a secure seal year-round – no matter how hot, cold, humid, or dry the Quad Cities climate gets. The result? Windows that stay tight, function smoothly, and resist air or moisture intrusion over time.
3. Low-Maintenance, High-Performance Finish
Every Infinity® window boasts a proprietary acrylic finish that’s three times thicker than competing window finishes. It stands strong against peeling, chalking, fading, and blistering – even under blazing sun or freezing conditions. In other words, they maintain their pristine appearance with minimal upkeep – no painting, scraping, or staining required.
4. Energy Efficiency That Makes Dollars and Sense
Thanks to superior sealing and advanced glazing options – including Low-E2, Low-E3, and Low-E3/ERS – Infinity® windows are designed to reduce heat transfer, decrease heating and cooling costs, and keep your home cozy and efficient all year long. That translates into a more comfortable home and real savings for you.
5. Tailored Design for Every Home
One size rarely fits all – especially when it comes to home style. So we offer a full lineup of Infinity® window styles: Double Hung, Casement (with Easy Wash® hinges), Awning, Bay & Bow, Sliders, and unique Specialty Shapes, including custom options.
You also have choices for interior and exterior finishes, hardware, grille patterns – and even EverWood® interiors that mimic the warmth of real wood without the maintenance. Whatever your home’s architectural style – modern farmhouse, traditional brick, or contemporary – you’ll find Infinity® windows that enhance your aesthetic vision.
6. Built to Withstand Harsh Weather
Built from fiberglass and engineered with high-performance sealing systems, Infinity® windows are made to endure what Mother Nature sends your way – be it midwestern wind, rain, hail, or temperature shifts. Their strength and watertight design help preserve your home’s comfort and safeguard its interior.
7. A Lifetime Warranty You Can Trust
Marvin backs Infinity® windows with a comprehensive Limited Lifetime Warranty – covering frame, glass, hardware, and finish. Mainstream Home Improvement also stands behind our installations with warranty-backed service, giving you total peace of mind. Interested in resale? The Infinity warranty even offers transferable coverage, making it a valuable selling point for your home.
8. Expert Installation – Because Details Matter
Even the best windows need expert installation to perform as promised. Our team – factory-certified, and with 20+ years of experience – executes every step with precision: removing old units, prepping and leveling openings, insulating, quality checking, and detailed trim work. Plus, each project receives a final walkthrough to ensure top-quality results before we’re done.
9. Transparent, Fair Pricing You’ll Appreciate
Quality doesn’t need to be complicated – or overpriced. At Mainstream Home Improvement, we deliver fair, competitive pricing without corner-cutting or hidden fees. Our Quad Cities roots mean we’re committed to providing honest estimates and exceptional customer care every single time.
10. The Last Window Your Home Will Ever Need
Between their fiberglass strength, stable performance, low-maintenance finish, and triple-layer warranty, Infinity® windows are crafted to last a lifetime. For Quad Cities homeowners, that means this could be *the last window replacement your home ever needs – saving future hassle and maximizing long-term value.
