Our take on the Therma-Tru Smooth-Star Fiberglass Prehung Exterior Door

The Smooth-Star is Therma-Tru's fiberglass entry door, sold prehung in a composite frame with an insulating core, brickmould, weatherstripping and ball-bearing hinges already fitted. The smooth fiberglass skin takes paint cleanly and resists dents, rot and rust, so it holds up where wood doors swell and steel doors ding. It suits homeowners replacing a front or side entry who want a Craftsman-style two-panel look without ongoing maintenance. Against wood doors it wins on durability and against steel it wins on dent and rust resistance; against premium fiberglass lines it is a simpler, lighter build with fewer glass and finish options.

Questions and answers

Is a fiberglass door better than steel or wood for an exterior entry?
Fiberglass resists dents, rot and rust and does not swell like wood, which makes it the lowest-maintenance of the three. Steel is cheaper but dents and can rust at scratches; wood needs repainting and can warp.
Does the Smooth-Star come with the frame and hardware?
Yes. It ships prehung in a composite frame with brickmould, weatherstripping and ball-bearing hinges fitted. You supply the lockset and handle.
Can I paint it a different color?
Yes. The factory finish is painted, and the smooth fiberglass skin accepts exterior paint. Lightly scuff and prime bare or chipped spots first so the new coat bonds.
What does right-hand inswing mean?
With the door closed and viewed from outside, the hinges are on the right and the door swings inward. Order the handing that matches your existing frame or your plan.
Does the insulating core make a difference?
The foam core and composite frame slow heat transfer better than a hollow or solid wood door. Pair it with good weatherstripping and a sealed sill for the full benefit.
Where is the Therma-Tru Smooth-Star Fiberglass Prehung Exterior Door cheapest?
At Lowe's, for $1,790.97, as of our latest check.
