Fiberglass vs wood doors: the big picture

If you want low maintenance and long lifespan, fiberglass is the winner. If you want unmatched warmth and authenticity, wood still reigns supreme.

Think of fiberglass as the no-fluff, weather-resistant athlete and wood as the timeless, stylish artist. Both can shine—but in very different ways.

According to Energy.gov, fiberglass doors generally offer better insulation and energy efficiency than wood, helping homeowners cut down on heating and cooling costs.

Strengths of fiberglass doors

1. Durability – Resistant to warping, cracking, and swelling, unlike natural wood.

2. Low maintenance – No sanding, staining, or sealing required every few years.

3. Design versatility – Can mimic wood grain with high-quality finishes.

4. Energy efficiency – Insulated cores improve thermal performance.

5. Cost savings – Typically cheaper upfront and in long-term upkeep.

Pairing fiberglass with fiberglass door frames boosts structural stability and further reduces the chances of warping.

Strengths of wood doors

1. Aesthetic appeal – Nothing matches the real look and feel of natural wood.

2. Customization – Easier to refinish, stain, or paint for a personal touch.

3. Heirloom quality – A well-maintained wood door can last generations.

4. Prestige – Wood doors are often associated with luxury homes and high-end curb appeal.

However, wood requires more maintenance—exterior sealing every couple of years—and can be vulnerable to moisture damage.
