What Are Fiberglass Doors?

Fiberglass doors contain three primary components: the frame (including stiles and rails), the core, and the skin. The stiles run vertically on either side of the door, while the rails provide top and bottom support. The frame itself is usually wooden or consists of durable composite material.

The core’s polyurethane insulating foam helps protect your home’s interior from the elements and acts as a soundproofing barrier. The door’s exterior, also called the skin, is high-impact, compression-molded fiberglass that can either resemble wood or add a pop of bright color.

Benefits of Fiberglass Exterior Doors

Fiberglass doors consist of the finest materials to capture the beauty of traditional wood but with higher performance. The benefits of fiberglass address the downfalls of wood, as shown below:


  • Resists dents and scratches
  • High durability
  • Requires minimal maintenance
  • Will not crack or split
  • Does not absorb moisture, thus eliminating the risk of rotting, warping, peeling, or bubbling


  • Can easily scratch
  • Tends to fade over time
  • Demands regular upkeep of refinishing every 1-2 years
  • May crack or split in extreme temperatures
  • Absorbs moisture, thus causing doors to rot and warp and the finish to peel or bubble

Customization Options

Several customization options are available to suit your individual taste, ranging from specialty glass to finish stains. All options can be applied to a single or double-wide unit.


Fiberglass doors offer two primary exterior textures: wood grain and smooth skin.

  • Wood grain. Yes, you can choose a wooden-textured door without using wood! The wood grain fiberglass offers the same nooks and crannies as actual wood but with increased performance.
  • Smooth skin. As the name suggests, smooth skin fiberglass doors have sleek exteriors. Their high durability can withstand numerous harsh conditions.


Panels add a bit of flair to your door. Choose from various arrangements and styles to create a look unique to your home.

  • Raised panels. Raised panels provide dimension to an otherwise flat door surface. They highly resemble traditional molded wood.
  • Flat panels. Flat panels on fiberglass doors don’t have detailed molding. Instead, they typically consist of a single, smooth skin panel and boast modernism.


Many fiberglass doors include glass to allow natural light. You can customize the type of glass and choose added features to enhance its appeal further.

  • Decorative glass. Decorative glass is far-reaching and includes privacy patterns like frosted or reeded and designs with lead caming.
  • Low-E glass. Low emissivity (Low-E) glass reduces energy consumption year-round. It works to reflect heat inside during the winter months and block infrared heat energy outside during the summer.
  • Blinds between glass. You can enjoy the privacy and convenience of blinds without the hassle of dusting or dangling cords. Two panes of glass protect the blinds, enhancing safety and performance. Easy control and limited visibility are significant benefits, not to mention a lifetime warranty to put your mind at ease.
  • Divided lites. Modern doors create the illusion of multiple glass panes by placing divided lites either affixed on the interior and exterior or within the glass. Divided lites can offer a traditional, historical look, as well as a more modern, minimalist vibe.

Finish Stains and Colors

Finish stains and paint colors can apply to wood grain and smooth skin textures. Perhaps you want to replicate a traditional appearance – in that case, select a factory stain color on a wood grain door.

Or, maybe, you wish to add personality to your home’s exterior – choose a bright, cheery color on your smooth skin door to do so. Your options are nearly endless.


Hinges, locks, and handles are integral parts of your fiberglass door. Whatever style you choose, select one of the following hardware finishes:

  • Brushed Nickel
  • Polished Brass
  • Black Painted
  • Oil-Rubbed Bronze
  • And more.
