I need new doors in my house and am thinking about going with pre-hung fiberglass door & frame.
I'm wondering if anyone has any exp. with them ?

I replaced my front door with a fiberglass one about 5 years ago. It's been a very good door so far. No problems.

I used to be a contractor (10 years) I can tell you, the fiberglass doors hold up very nicely. They do not have the problems associated with wooden doors (warping, binding, splitting etc.) nor do they have the issues associated with steel doors (cold, dents easily (dings), weight etc.). Fiberglass is the best of both worlds and they look very nice!

O.K. thanks, I'm also wondering about being able to hang a screen door onto the fiberglass frame.

The fiberglass doors I`ve used didnt have a fiberglass frame....

and we as a company use a LOT of fiberglass doors...

they have now (Pella at least) also come out with fiberglass window /window frames...hold up better than vinyl windows

Right. Mine has a wood frame.

The ones I have installed also had wood frames...

Doug,

Over here in cold Mpls... I have fiberglass doors on our house that I installed 3 years ago, and although they still look like new and appear to be very energy efficient, the foam seals around the jambs do not seem to seal as nice as steel doors. With a steel door, the weatherstripping has magnetic strips to "grab" the door like a refigerator, but the fiberglasss ones don't. If you hold your hand near the bottom and top corners of the doors, you can feel air movement. This is even with good quality storm doors over the fiberglass. Once the doors are installed, there is not much for further adjustment, other than the bottom sill weatherstip.

Had I to do it again, I'd go back to steel doors, but thats just my opinion.

And yes, the frames are still wood, even with the fiberglass door.

I went to Menards today and looked them over again and I think I'll go with a steel door.
And yes all the frames are wood I don't know what I was thinking.

I wonder how much heavier a steel door is than a fiberglass ?

I think they are the same weight, approximately. One thing about the steel door, paint it a light color because they tend to expand a lot when they get hot. I painted our old one dark brown to match the trim. It got warm and stretched the plastic molding around the window and cracked it. That's why we switched to the fiberglass door. The cracked trim looked bad....

If you plan on installing a storm door over the steel door, you very well may encounter issues with heat/cold expansion etc. In fact, most steel door mfg. have a label right on them stating do not install storm door etc. What they expect people to do is beyond me, but it is a potential issue...

Thanks I'll keep that in mind.
I do like the magnet in the weatherstrip on the steel doors.
