    Rapidly gaining market share, fiberglass doors are known for their resistance to moisture, insects, warping and changes in humidity. Thick outer skins of fiberglass surround an inner foam core and a steel framework that provides strength and stability.

    Fiberglass excels at mimicking the colors and grain patterns of real woods such as cherry, oak and mahogany.

    Heads up: Single-layer versions can be brittle.

    Insulating value: R-4 to R-12

    Cost for a 16-by-7-foot double door: $1,100-$1,800.
