Therma-Tru Grid Entry 68-in 80-in x 6-9/16-in Fiberglass 3/4 Lite Right-hand Inswing Black Painted Prehung Front Door with Sidelights vs VDOMDOORS Manux 8661 Prehung Entry Door

Buy the Therma-Tru if you want a fiberglass door that resists dents, rust and rot and comes with sidelights in a wide 68-inch unit. Buy the VDOMDOORS if you want a steel door with two sidelites, a multi-point lock and five keys included. Owners of fiberglass doors report they hold paint and shrug off dings better than steel, which can dent and rust at the bottom edge. The VDOMDOORS has the sturdier hardware package, but its metal-plastic core and thinner slab make it the lesser choice for a harsh climate.

  • Choose the Therma-Tru Grid Entry if you need a wide prehung unit with sidelights, an insulating fiberglass slab and a finish that won't rust or dent.
  • Choose the VDOMDOORS Manux 8661 if you want a steel entry door with two frosted sidelites, European roller hinges and a lock that ships with five keys.

Questions and answers

Which is better for a cold climate?
The Therma-Tru. Its fiberglass slab and insulating core hold heat better than the steel-over-plastic build of the VDOMDOORS, and fiberglass won't rust from condensation.
Which lasts longer?
The Therma-Tru. Fiberglass resists dents, rust and rot, while steel doors can dent and rust along the bottom edge over the years.
Is the VDOMDOORS worth stepping up to?
Only if you want two sidelites and the multi-point lock with five keys. On material and insulation, the Therma-Tru is the stronger door.
Which has better security hardware?
The VDOMDOORS ships with a multi-point lock and five keys. The Therma-Tru is prepped for a lockset and deadbolt but you choose and buy them.
Which is easier to install?
The Therma-Tru. It is lighter and comes prehung with weatherstripping and brickmould. The VDOMDOORS unit weighs about 120 lbs and needs two people.
Do both come with sidelights?
Yes, but differently. The Therma-Tru has one sidelight in a 68-inch unit; the VDOMDOORS has two 14-inch frosted sidelites.
