Therma-Tru Benchmark Fiberglass Door vs National Door Company ZZ364628R Fiberglass Door

Buy the Therma-Tru Benchmark if you want a complete, storm-rated prehung door with a composite frame, Low-E glass and a painted finish. Buy the National Door Company slab if you want a simple full-lite fiberglass door and will supply your own frame and hardware. The Benchmark is the more finished product: it ships prehung, carries a large-missile impact rating and Wind Zone 4 rating, and its fiberglass skin resists warping, rot, dents and rust. The National door is a plainer primed slab that needs painting and framing, and it swings out rather than in.

  • Choose the Therma-Tru Benchmark if you need a prehung, impact-rated entry door with a composite frame, Low-E glass and a factory finish.
  • Choose the National Door Company if you want a basic full-lite fiberglass door and plan to handle the frame, finish and hardware yourself.

What reviewers say

Therma-Tru Benchmark Fiberglass Door

Owners value the door for its durability in harsh climates and its clean Shaker aesthetic. It is praised for its rot-resistant composite edges but noted for requiring precise installation due to its weight.

What people mention
  • DurabilityPraisedFiberglass construction prevents the rotting, warping, and denting common in wood or steel doors.
  • Weather ResistancePraisedThe Large Missile Impact rating and Wind Zone 4 certification make it suitable for coastal storm protection.
  • InstallationMixedWhile prehung with ball-bearing hinges, the heavy panel requires two people to install safely.

Questions and answers

Which is better for a hurricane zone?
The Therma-Tru Benchmark. It is Large Missile Impact Rated and rated for Wind Zone 4 at +75/-80 psf design pressure. The National door carries no impact or wind-zone rating.
Which lasts longer?
Both use fiberglass skins that resist rot and dents. The Benchmark adds a composite frame and edges that resist moisture, and its factory finish is backed by a 10-year limited warranty. The National door depends on how well you paint and frame it.
Is the Benchmark worth stepping up to?
Yes if you want a complete prehung door with frame, weatherstripping, Low-E glass and storm ratings. The National door only makes sense if you already have a frame and want a plain full-lite slab.
Can I use the National door as an inswing front door?
No. It is listed as a right-hand outswing door. The Benchmark comes in right- or left-hand inswing.
Which lets in more light?
The National door. Its full-lite clear glass runs most of the door height. The Benchmark uses smaller divided lites.
Do either include a lock?
Neither ships with a lockset. The Benchmark is prepped for a lockset and deadbolt with an ASSA 2002 Connect lock case; the National door lists no lock prep.
