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 Fiberglass Front Entry Door with Side Lites

Buy the Therma-Tru if you want a wider, better-insulated entry with a thicker impact-rated frame and a real lock prep; buy the Northside door if you want a simpler primed unit with sidelights that you plan to paint yourself. The Therma-Tru has the stronger spec sheet: 6-9/16-inch aluminum impact frame, insulating core, weatherstripping and brickmould included, and an ASSA 2002 lock case. The Northside door is a thinner 4-9/16-inch frame with triple-pane decorative glass and a primed finger-jointed surface. Neither has a deep pool of owner reviews, so judge them on build and fit for your opening.

  • Choose the Therma-Tru Grid Entry if your rough opening suits a 68-inch-wide unit and you want a thicker impact frame, insulating core and factory lock prep.
  • Choose the Northside fiberglass entry door if you want a narrower 60-inch unit with 10-inch sidelights, triple-pane glass and a primed surface you will paint.

Questions and answers

Which is better for a cold climate?
The Therma-Tru. Its insulating core, weatherstripping and thicker impact frame hold heat better than the Northside unit, whose core is not specified.
Which has better glass?
The Northside door lists insulated triple-pane decorative glass. The Therma-Tru lists decorative glass without a pane count, so the Northside has the edge on glass spec.
Which lasts longer?
Both are fiberglass, which resists rot and dents. The Therma-Tru adds an aluminum impact frame and factory paint, which usually hold up better than a primed surface you paint yourself.
Can I get a left-hand swing?
Only on the Northside door, which offers left or right hinge inswing. The Therma-Tru is right-hand inswing only.
Is the Therma-Tru worth stepping up to?
Yes if your opening fits 68 inches and you want the thicker frame, insulating core and lock prep. Skip it if you need a left-hand swing or a 60-inch unit.
Do both include trim?
Yes. Both include brickmould trim, and the Therma-Tru also includes weatherstripping.
