Comparing Fiberglass vs. Wood Windows

Comparing Fiberglass vs. Wood Windows

Whether your client has a modern or traditional home, wood and fiberglass windows are a stunning addition. Learn about the differences so you can help them choose between the two materials.

Architectural Style

When comparing fiberglass and wood windows, it’s smart to consider your project’s architectural style.

Contemporary

Steel windows are often preferred for contemporary homes, but they also have a high price tag. You can achieve a similar look with Pella® Impervia® fiberglass windows, which feature sleek profiles and clean lines. They’re available in an up-to-date color palette including black. With optional between-the-glass grilles and complementary hardware, you’ll be able torealize your design vision.

Working with a client who enjoys the beauty and warmth of wood? There’s a modern window for them in either the Pella® Reserve™ or Pella Architect Series® collection. These windows feature expansive glass with minimalist finishes.

Traditional

Wood windows are a timeless style for traditional homes. When your clients need something highly customizable, Pella® Lifestyle Series is a great fit. These windows offer style flexibility as well as exceptional performance options and 37 time-tested purposeful innovations.

When you have a client who wants wood windows that stand out, there’s the traditional Pella Architect Series. These windows feature finely detailed grilles and sashes, timeless style and the best limited lifetime warranty for wood windows.1

Cost

Wood is a premium window material. While cost can vary depending on your specific project, wood windows are generally more expensive than fiberglass.

Customization

From grilles to hardware and glass options, both fiberglass and wood windows are highly customizable. However, there are several more extra features available for wood windows, such as our integrated blinds and shades in Pella Lifestyle Series. These window treatments are tucked between the glass, which protects them fingerprints and allergens.

Energy Efficiency

Wood windows are highly energy efficient. In fact, our Pella Lifestyle Series windows are manufactured in styles that meet or exceed ENERGY STAR® guidelines in all 50 states.3 Your clients can personalize their energy efficiency with glass windows like triple panes or dual panes with insulating argon gas.

Fiberglass won’t expand or contract as temperatures change, so the frame isn’t susceptible to cracking or gapping. Your clients can also customize it with energy-efficient dual and triple-pane glass options with argon to slow heat transfer.

Durability

Fiberglass is an extremely durable material. It won’t rot or corrode, and it naturally stands up to water and bugs. Impervia windows have been tested in -40oF to 180oF and meet rigorous performance requirements for commercial buildings.2

Wood windows have stood the test of time, as they’ve been used for hundreds of years. We treat ours with the exclusive EnduraGuard® formula, which delivers substantial protection on every surface. Then, we finish them with strong extruded aluminum or aluminum cladding to preserve the exterior.

Maintenance

Fiberglass windows are the lowest-maintenance option. Impervia is finished using a heavy-duty powder coat finish that resists chipping, chalking and fading. These windows won’t ever need to be painted or refinished.

The outside of our wood windows is enclosed by extruded aluminum or aluminum cladding, depending on the product line your clients decided on. This greatly lowers the upkeep they’ll need to do. For the interior side of the window, they can compare factory-prefinished stains and paints, or stain and paint the windows themselves.
