Hi,


I'm currently working on my dedicated room which will have communicating doors.


Following advice from the forum, I tried to buy a pair of Masonite solid core door (1'' 3/4). Problem is, all major supplier near me (Montreal, QC) can only provide me with the slab and can't have the door pre-hung.


Since I was set on getting a Masonite door since I know their exact spec (STC), I bought the slabs and I'm now trying to build the jamb myself. Local supplier only have standard 4 9/16 jamb that are not deep enough for my double wall construction and are not solid enough for a solid core door.


So, what kind of jamb should I use ? 3/4'' jamb with stop ? Single rabbetted jamb, or double ? Does it really matter in terms of soundproofing ? I used double walls, DD and GG all around.


I'll be adding speciality weatherstripping, gasketing and an automatic bottom.


I tought I needed a rabbeted jamb because that's how my garage door (the one leading to the house) is built and it's a fire-rated door, so similar to what I bought. But since I'll be buying standard notted pine 2x6 to build my jamb, I would have to machine the wood to get a rabbet. I don't have tools to do this nor the experience. I'm all for learning new stuff but if I can avoid this it would be simpler.


Thanks for the suggestions !

You cut the jamb and add a door stop, you can cut a kerf on the edge of the stop with a table saw and that will create a rabbet. Add press in weather stripping, Or skip that and use adjustable rubber gasket perimeter door seals and substitute for the stop or on top of the stop.

So a rabbeted door stop doesn't help with the "soundproofness" of a door with it's added width vs a jamb with an applied stop ?


For reference, this is what I'm referring to when talking about a rabetted jamb, just in case I'm not using the appropriate lingo :

my mistake didn't know what you were reffering to. You could probably make that with two pieces of wood glued together. Rabbet versus Smaller door stop and soundproofing, I think it really is a function of the quality of the door seals you mount on either.

Thanks alot.


I've been thinking about this last night and I think I'm overthinking this jamb question. I'll go with a simple applied stop, deep enough so I can apply some weatherstripping.


Like you said, the seal will do most of the work anyway so I shoul concentrate on those.


Thanks for the input
