Door Construction

Classic-Craft® Premium Entryways

  1. Enhanced Weather Resistance

    No more worries about rotting, warping or twisting. Classic-Craft premium entryways are designed and tested to resist extreme weather conditions and the damaging effects of moisture. Both the top and bottom of the door are protected by composite rails for a longer-lasting entryway

  2. Solid Security

    Classic-Craft premium entryways feel solid and close with authority. A 4-1⁄8″ wide beam of engineered lumber runs from the top to the bottom of the locking side of the door to add mass and rigidity, giving the door weight and a natural wood feel.

  3. Excellent Durability

    Built to stand up to the elements and years of wear, Classic-Craft’s fiberglass skins are thicker than other standard fiberglass doors to provide added durability and better long-term performance.

  4. Higher R-Values

    Classic-Craft premium entryways contribute to an energy-efficient home. A polyurethane foam core provides up to four times the insulating R-Value of wood.*

  5. Edge-to-Edge Moisture Protection

    Resist moisture at every turn – and along every edge. Classic-Craft premium entryways have hardwood and composite edges that help prevent moisture penetration.

Fiber-Classic® & Smooth-Star® Doors

  1. Weather Resistance

    Composite rails protect the door at the top and bottom edges to help block moisture that can wick into doors.

  2. Solid Security

    An enhanced lock block combined with 1-1⁄4″ engineered lumber lock and hinge stiles increase rigidity and stability.

  3. Durability

    With very little maintenance, a fiberglass door can bring a home years of durability. Unlike wood, fiberglass will not warp or rot. And, unlike steel, it will not dent or rust.

  4. R-Values

    Built with a polyurethane foam core, Therma-Tru fiberglass doors insulate against cold and heat for exceptional energy efficiency, offering up to four times the insulating R-Value of wood.*

Why Fiberglass?

After 25 years, fiberglass doors continue to prove to be the most reliable and advanced material for entry doors. Fiberglass material is built to provide the endless strength a steel door offers, and the elegant look of wood doors. Fiberglass doors have proven to be a must-need for homeowners due to their security, strength and energy-efficient options. Therma-Tru not only pioneered the fiberglass door category but they continue to lead the industry.
