Wood Types Custom Window Solutions


Architect Series products are available in Mahogany, Alder, Douglas Fir or Pine. White Oak, Red Oak, Cherry and Maple are some of the additional options available on a custom basis. Please contact your local Pella representative for details.

All wood types are treated with Pella's EnduraGuard® wood protection so you can expect years of dependable performance.

Pine

Unfinished Pine windows offer a versatile grain pattern, making them the perfect blank canvas they can be finished in a light color for a fresh, modern look. Or they can be stained a rich color to resemble darker woods.

Douglas Fir

Douglas Fir windows have a beautifully distinct grain pattern. But their beauty is more than skin deep. Douglas Fir is known for its extra strength and durability.

Alder

Pella is one of just a few manufacturers to offer Alder windows the rugged beauty of Alder will make any project stand out from the rest. Alder windows offer a beauty and stately elegance that are the perfect complement for buildings with a more rustic design. This grained hardwood is coveted for its characteristic random knots and checks but also for its striking color.

Mahogany

For centuries, it has been sought after for its warm, rich color. Today, Pella brings the fine-furniture elegance of Mahogany to life. Now the windows can blend tastefully with other Mahogany woods in a building including millwork, doors, furniture and floors.

White Oak

Naturally hard and weather resistant. Architect Series White Oak windows and doors have a straighter, tighter grain pattern than Red Oak. The color ranges from a dark gray to a whitish-gray and its glassy surface makes staining more consistent.

Red Oak

Legendary strength and durability. Used for generations in millwork, furniture, and floors, Pella brings the beautiful strength and durability of Red Oak to Architect Series windows and doors. Red Oak has a slightly pink tone in its raw form and boasts a broad-grained pattern that allows stain to sink in, highlighting the grain even more.

Maple

Sturdy and resilient. Architect Series Maple windows and doors offer a tight, closed finely grain pattern. It's smooth texture moves in the same direction as the grain. The basic tone is off-white, often with slight reddish tint.

Cherry

A luxurious wood that ages beautifully. Architect Series Cherry windows and doors have a satiny-smooth texture and rich, warm color with light to darker tones of red. The intensity of the color builds with time and exposure to light and will deepen to a rich wine color over time.

Pella EnduraGuard wood protection offers advanced protection against the effects of moisture.

Here's the difference:

  • Pella's EnduraGuard® protection formula has three active ingredients to provide advanced protection against the effects of moisture, decay, stains from mold and mildew. Plus an additional ingredient adds protection against termite damage
  • EnduraGuard wood protection has a greater concentration of protective ingredients compared to major competitors using immersion treatments1

NOTE: Wood is a product of nature; grain pattern will be unique and may vary on each window or patio door. Actual finish colors may vary from those shown due to the unique nature of wood.

1Based on the average measurement of retained active anti-fungal ingredients and performance solids (Borates and Trialkyl Nitrogen Oxides) on sashes and frames of major competitors using immersion treatment.
