If your current windows are failing, you’ll want to replace them with a more durable material to ensure lasting results. Understand that you’ll either pay initially for high-end windows—or pay later when low-end windows need extra maintenance and repairs, and don’t last.
Higher-end windows hold their value due to their resilient makeup, enduring beauty, and reliable energy efficiency. Read on to discover the many reasons durable fiberglass windows are well worth their initial investment.
The Problem with Some Window Materials
Why vinyl windows fail
Vinyl windows are cost-effective upfront, but they are prone to chipping, cracking, warping, and fading. And their lifespan is shorter than other window materials.
Wood window issues
Wood tends to incur moisture damage which leads to rot, mold, mildew, and other costly issues. They require a lot more upkeep than fiberglass frames, and if they aren’t finished regularly, they won’t live out their lifespan.
Why Fiberglass Windows Are Worth It!
Fiberglass windows are an investment you make initially, and they last a lifetime. Their durable makeup (think hardhats and canoes) stands up to the weather and endures while looking gorgeous and increasing your home value.
Durable Ultrex® Fiberglass
Eight times stronger than vinyl, and three times stronger than vinyl/wood composites, these tough windows will go the distance! When you choose strong fiberglass windows, you can rest at ease knowing they will last!
Ultrex is pultruded fiberglass made with extremely hard-wearing, non-corrosive material that gives you years of nearly maintenance-free endurance. Because of their durable makeup, they won’t need to be replaced as often as other window materials.
Desirable Low Maintenance
The tilt-in convenience of these gorgeous windows delivers easy cleaning inside and out. It saves you the hassle (and risk!) of climbing a ladder to clean your second-floor windows.
Optional Wood Finish

Variety of Styles
When you choose fiberglass windows, you are not limited when it comes to captivating styles and shapes. You can go with classic double-hung, sleek casement, expansive slider, convenient awning, stylish round-top, generously appointed bay and bow windows, and unique specialty-shaped windows. You’ll get the perfect style to complement your home’s design.
Precise Installation
There are two primary ingredients to long-term window performance: quality materials and professional installation. You can’t overlook the value of a perfectly placed window in your home. When you hire a reputable contractor (like us!) to install your fiberglass windows, you’ll avoid problems like chilly drafts seeping into your house in the winter, a shortened window lifespan, increased energy bills, and unwanted repairs.
Energy-Saving Low-E Glass and Argon Gas
The single-paned windows that builders likely put into your home won’t deliver the energy efficiency of today’s double- or triple-pane, energy-efficient, noise-canceling fiberglass windows. When you choose Infinity by Marvin fiberglass windows, you get multiple panes with argon gas between the panes to increase insulation from temperatures and noise. And with Low-E glazing, your windows will safeguard your home from UV rays that could otherwise damage your furniture, flooring, and drapes. With fiberglass windows, you get higher energy efficiency and less heat loss so your St. Louis home stays warm in the winter and cool in the summer.
Customized Windows
Get the perfect window size and shape for your St. Louis home, including custom specialty windows. Ensure your home gets a weathertight fit that keeps your heating and air conditioning unit from overworking (and wearing out faster).
Increased Home Value
High-end windows positively impact your house’s resale value. They make your home more desirable when it comes time to sell.
Easy Operation
Fiberglass windows are easy to use. They operate smoothly and quietly over their lifespan.
