Like to know what you guys are using for door jambs? Being that the ICF walls are much wider then the stick built trash that 95% of builders are building and therefore all products cater to that much inferior process? I will probably go with some sort of composite jamb material. I am all about maintence free or at least reduced maintenance.

I think I am going to go with fiberglass...

On the second page of this thread I list several other threads where this has been discussed. You should see pics of what I did in some of those threads.

In my posting of Jan 21, 2010 in this thread are links to some pics of what I did. I used standard doors built for standard 2 x 4 walls.

I'm using standard width pre hung doors. The widest threshold available barely reaches 9", so even special ordering them, you are still short. Install the door as usual, then use 1x lumber to extend the inside door framing the needed amount. The only drawback to this is the doors won't open all the way back against the inside wall as they usually would.

I can make my own jambs out of wood but I want to use the better stuff. I just thought that some would know of some places that do make jambs for our application? I will check the other treads as mentioned above.

I could be wrong but I suspect the pre-hung door business is too fragmented and shipping distance constrained to make it profitable for anyone to create a specialty business for ICF walls. When I built my house in 2008 I bought my doors from a local lumber company who had their own door shop. They bought slabs from various manufacturers, installed the windows, built the jambs, and hung the doors. The hinges are stamped Lloyd Lumber.

You might be able to find a door shop reasonably close who will make the jambs like you want. I have my doubts you'll find any manufacturer who sells and distributes nationally pre-hung door made for ICF. For your sake I hope I'm wrong. Another inhibitor is the variation ICF builders take in deciding how to install doors into ICF walls. My approach demonstrates that. I'm not sure if any ICF builder does like I did, but they sure work good.

Those two reasons are why I did mine like I did. Mine swing full inside, and the standard threshold laps over the floor and stoop.
