When it’s time to replace your windows, it’s useful to learn about various window frame materials because choosing the right material is just as important as selecting the right glass. Your frame impacts durability, energy efficiency, style, and long-term maintenance. At New Windows for America, we’ve helped Denver homeowners for over 25 years choose the best windows and frame materials for their home, climate, lifestyle, and budget.

Here’s a breakdown of the four most common window frame materials—vinyl, wood, aluminum, and fiberglass—with a closer look at why vinyl and fiberglass are top choices for Colorado homes.

Vinyl Window Frames

Pros:

• Highly Energy Efficient – Vinyl is an excellent insulator, helping reduce heating and cooling costs.
• Low Maintenance – No painting, staining, or refinishing required—just occasional cleaning with soap and water.
• Affordable – Offers one of the best cost-to-performance ratios in the industry.
• Moisture Resistant – Won’t warp, rot, or corrode, making it ideal for Denver’s changing weather.
• Variety of Colors and Styles – Today’s vinyl windows can mimic wood grain or come in a wide range of color options.

Cons:

• Less customizable than wood in terms of intricate shapes.
• Lower-end vinyl can fade over time if not UV-protected (we only offer premium vinyl to prevent this).

Why We Love It: Vinyl windows are a smart, budget-friendly choice for Denver homeowners looking for excellent energy efficiency, minimal upkeep, and long-lasting performance.

Wood Window Frames

Pros:

• Classic Beauty – Offers a timeless, natural look that can be stained or painted.
• Great Insulator – Naturally energy efficient when properly maintained.
• Customizable – Easy to shape and finish to match unique architectural designs.

Cons:

• High Maintenance – Requires regular painting or sealing to prevent rot, warping, and insect damage.
• Higher Cost – Typically more expensive than vinyl or fiberglass.
• Not Ideal for All Climates – Can swell or shrink with Denver’s temperature swings if not well maintained.

When to Choose: Wood windows are the best choice for homeowners seeking a traditional aesthetic and who are willing to commit to the upkeep that they need.

Aluminum Window Frames

Pros:

• Strong and Lightweight – Allows for thinner frames and larger glass areas.
• Durable in Mild Climates – Performs well in areas without extreme temperature changes.

Cons:

• Poor Insulator – Aluminum conducts heat and cold, making it less energy efficient in Denver’s climate.
• Prone to Condensation – Can lead to moisture issues.
• Not the Best Choice for Colorado Homes – Our harsh winters and hot summers make aluminum less practical.

Our Take: We typically recommend steering clear of aluminum windows in Denver for better energy performance and comfort.

Fiberglass Window Frames

Pros:

• Superior Strength – Stronger than vinyl and resistant to warping, swelling, or rotting.
• Highly Energy Efficient – Excellent insulating properties for year-round comfort.
• Low Maintenance – Like vinyl, fiberglass doesn’t require painting or refinishing.
• Long Lifespan – Can last 30+ years with minimal upkeep.
• Paintable – Allows for color changes without compromising durability.

Cons:

• Higher Initial Cost – More expensive than vinyl, but often worth it for the long-term benefits.

Why We Recommend It: Fiberglass offers a high-end, durable, and energy-efficient option—perfect for Denver’s weather extremes. It’s a great investment for homeowners who want premium performance with minimal upkeep.

Vinyl vs. Fiberglass: Which is Right for You?

If you’re on a tighter budget but want excellent energy efficiency and minimal maintenance, vinyl windows are a fantastic choice.

If you want the ultimate in durability, strength, and long-term performance—and are willing to invest more upfront—fiberglass windows are hard to beat.
