Our take on the Therma-Tru Therma Tru Entry Fiberglass

This is a Therma-Tru fiberglass entry door, 36 inches wide and 96 inches tall, in a left-hand single-door configuration with a 4-9/16-inch frame depth. Fiberglass skins over a foam core resist dents, rot and moisture far better than wood, and the white finish needs no repainting. It suits homeowners replacing a front or side entry who want a solid, low-maintenance door that can be stained or painted later. Against steel doors it insulates better and never rusts; against solid wood it costs less upkeep and holds up to weather. Reviewers of Therma-Tru fiberglass lines generally praise the build and the look, while noting that installation and hardware choices matter a lot.

Questions and answers

Is fiberglass better than steel for an entry door?
Fiberglass resists dents, rust and moisture better than steel and insulates comparably. Steel is usually cheaper and stronger against impact but can dent and rust where the finish chips.
Can this door be painted or stained?
Yes. The white fiberglass surface accepts paint, and Therma-Tru offers stain kits for a wood-grain look. Follow the maker's prep steps for a lasting finish.
What does left-hand mean for this door?
Left-hand means the hinges sit on the left when you view the door from outside. Confirm the swing direction before ordering so the door opens the way you need.
Does it come with a frame and hardware?
This listing is the door in a left-hand single configuration with a 4-9/16-inch frame depth. Check the specific listing for whether a prehung frame, sill and hardware are included.
What rough opening does a 36 by 96 door need?
Plan for roughly 2 inches more than the door width and about 2-1/2 inches more than its height for the rough opening. Measure your existing opening before ordering.
Where is the Therma-Tru Therma Tru Entry Fiberglass cheapest?
At Lowe's, for $748.00, as of our latest check.
