Product Details

Fiber-Classic Oak Collection Flush Glazed Fiberglass Double Entry Door - FC8691

  • Weather Resistance
    Composite top and bottom rails help protect the door edges from moisture infiltration, minimizing the risk of warping, swelling, or deterioration.
  • Security
    Engineered with a 1-¼" lock stile made from solid engineered lumber and an enhanced lock block, this fiberglass door is up to 30% more resistant to kick-ins than standard steel doors.
  • Durability
    Unlike wood, fiberglass won’t warp, crack, or rot—and unlike steel, it won’t dent or rust. This door delivers long-lasting performance with minimal maintenance required.
  • R-Values
    A polyurethane foam core provides up to four times the insulating value of wood, helping to maintain interior comfort and improve overall energy efficiency.

ThermaTru's Fiber-Classic Oak Collection doors blend timeless woodgrain style with modern performance. With matching styles and glass designs across collections, this door provides flexibility for Grand Front Entryway, patio, or utility entrances—all at a great value.
