Our take on the Therma-Tru Classic Collection Fiber-Classic Left-Hand Inswing Prehung Entry Door

The Therma-Tru Classic Collection Fiber-Classic is a prehung exterior entry door with a fiberglass skin over an insulating core, a stained woodgrain finish, and a two-panel Craftsman design. It comes assembled in a composite frame with brickmould and weatherstripping, so it installs as one unit. The fiberglass skin resists dents, rot and rust, which is the main advantage over a solid wood door that needs repainting and can swell or split. It suits homeowners replacing a front entry who want a wood look with less upkeep; the trade-off is that fiberglass doors are heavier to hang and the stained finish is factory-applied rather than something you can easily refinish.

Questions and answers

Is this door better than a solid wood entry door?
For most exteriors, yes. The fiberglass skin will not rot, warp or rust the way wood can, and it holds its stained finish with far less upkeep. Wood still wins if you want to sand and refinish the door yourself.
What does right-hand inswing mean?
Standing outside facing the door, the hinges are on the right and the door swings inward. Measure your existing opening and hinge side before ordering, because the handing cannot be changed after the frame is built.
Does it come with the frame and trim?
Yes. It is prehung in a composite frame and includes brickmould and weatherstripping. Hinges are ball-bearing. The lockset and handle are not part of the door.
How energy efficient is it?
The insulating core and weatherstripping reduce heat transfer and drafts compared with a hollow or uninsulated door. The clear glass is the weakest point for insulation, so a storm door or insulated glass helps in cold climates.
Can I repaint or restain it?
The door arrives stained. A factory stain is difficult to strip or recolor cleanly, so plan on the finish you order. Light scuffs can be touched up, but a full color change is not a simple job.
What size opening does it fit?
It is a 36-in by 80-in door in a frame about 6-9/16 in deep, sized for a standard exterior wall. Confirm your rough opening and wall thickness before ordering.
