Forum Title: Hanging prehung interior door
I have heard different ways to install a prehung door. One says to center the door jamb in the rough opening and shim, and the other says to set the hinge side of the jamb tight against the trimmer stud and shim as necessary. It seems there would be more rigidity with the hinge side tight against the jamb. Thoughts, please. Greg

Although I've never heard of such a thing...I'm sure they make something. Insulation issues are a valid concern, but they might address that with some sort of foam insulation. Though how you would put a (approx) 1 1/2 - 2 thick panel in a std 2x4 framed wall and get adequate sealing and insulation is beyond me.

One tip is to buy #4 wood shakes to use as shims. Much more gradual taper and a lot wider then those wood wedges Big Box sells. I was lucky enough to get them at a place the made up small bundles out of the usual large ones but even if you have to buy a full bundle they are worth the cost. I doubt though you will find them at big box. Try a real full service lumberer yard.

And when you do shim the door you usually place two tapered shims together to create a flat surface. (like two triangles put together to form a rectangle) Sticking one tapered shim behind the hinge, then nailing it can often twist the door jamb due to the taper of the shim.
