When building a structure, what are the pro's and con's of a pressure treated treated sill plate and a bottom "Shoe". I have heard that I should use just the sill plate, and others say put another plate on top of that one.. I am wit's end as I need to have this built ina few weeks and before I start framing the walls... I kind of need to know.
I want to use 10' wall studs, with the two top plates. Do I have one bottom or two?

A single pressure treated 2 x 6 sill plate is used prior to supporting floor and rim joisting. If this is for a garage wall, still use a 2 x 6 PT plate with the required J bolts in the stemwall or slab pour. If the walls are blind wall framed, then you need to use a 'sole' plate before you raise the wall. Nm wirez

Okay... The garage floor is obviously flat, with a 9" wall all around (Due to the weather here) The only cut-outs are for where the cars come in and out. I have the J-bolts and the PT 2x6, with sill seal all ready to go. The question really is, do I need another plate to go on top of the PT sill plate? As in, the wall studs can either stand on one piece of flat wood or two?

PS - What is a blind framed wall?

A blind wall framing is when the wall is framed on the floor and then tilted up into position. Without a sole plate the tilt up will not be a way to go. If you are wall framing in place, then toe-nailing the wall studs into the sill is normal construction method.

We always use 1 treated sill plate

Glavine,

You are absolutely right. The PT sill plate is in contact with structure foundation whether blindwall or built-up stud framing is used. The blind wall framing can use PT but it takes a lot more time to notch or pre-drill and align before tilt-up in a garage. A sole plate on PT sill is usually a more quick way to go in pre-fab with the PT wet set with J bolts in the pour. Tx, nm
