Therma-Tru Grid Entry Fiberglass Front Door vs VDOMDOORS Manux 8661 Prehung Entry Door

Buy the Therma-Tru if you want a stained fiberglass Craftsman door that resists dents, rot and moisture and fits a standard 36 x 80 opening with brickmould trim. Buy the VDOMDOORS if you want a white steel door with two frosted sidelites for a brighter entry and a multi-point lock with keys. The Therma-Tru is the safer long-term pick for most US homes; the VDOMDOORS adds glass and sidelites but is heavier, needs a wider rough opening, and its metal-plastic core and European hinges are less proven in cold climates.

  • Choose the Therma-Tru Grid Entry if you want a durable stained fiberglass door with decorative glass and a classic Craftsman look that handles weather well.
  • Choose the VDOMDOORS Manux 8661 if you want a white steel entry with two frosted sidelites for extra light and a keyed lock set included.

Questions and answers

Which is better for a cold climate?
The Therma-Tru. Fiberglass does not rust or swell with moisture and holds up through freeze-thaw cycles better than a steel skin over a metal-plastic core.
Which lets in more light?
The VDOMDOORS. It has five frosted glass panels plus two 14-inch sidelites, while the Therma-Tru has a single decorative glass lite.
Which is easier to install?
The Therma-Tru. It is a standard 36 x 80 prehung unit with brickmould, while the VDOMDOORS unit measures 38 x 82 with sidelites and weighs about 120 lbs.
Is the VDOMDOORS worth stepping up to?
Step up if you want sidelites, frosted glass and adjustable European hinges. Skip it if you want a proven fiberglass door in a standard opening.
Which lasts longer?
The Therma-Tru is likely to last longer outdoors. Fiberglass resists dents and moisture, while steel can dent and its core is less proven in harsh weather.
