Basement Framing

We started framing our basement and come across a few areas that I am looking for someone to help point me in the right direction.

First of all, I am very much new at framing, as this is my real first project in regards to framing.

I have started framing my bathroom walls. I will have 1 wall that will be 2x6 (plumbing pipe) and it will meet a 2x4 wall. Any tricks or suggestions on making the 2x6 wall corner to the 2x4 wall?

Also, I have the main sewer pipe running along the entire wall. I want to build a soffit, but the pipe has a pitch, If i go to the lowest point of the pitch, the soffit will cover the top of my door walk out. Should i just create 2 soffits?

As you can tell from my questions, I am very much new at this....

Thanks for your all your help.....

Basement Framing

I'm a novice myself so I can't offer much advice but just like you I have started framing my basement and I have already learned a couple things that might help you.

If you are framing a stud wall against a poured foundation wall, don't frame it tight to the wall. My wall was not perfectly straight and yours probably isn't either. Especially if it's a poured wall. Keep your stud wall about an inch away from your basement wall and you can keep it plum, level and square.

I have a sewer line that runs parallel with the top of my stud. I could have built a soffit around it but I kept the top of the wall below the sewer line and installed brackets up to my floor joists. This is working pretty well. Good luck.

Basement Framing

for framing basements ALWAYS have the stud wall a minimum of 1" away from the foundation, so for a 2x4 wall the face of the wall should be 4 1/2" inches away, mark this on both ends of the wall and snap a line through.. check in a few spots to make sure you have 4 1 /2" distance between the line and the wall. if its more in the middle thats fine, if its less bring the wall out a little more

for creating the inside corner i use a couple different methods. i run my plates full length, then the stud in the corner will be just before the joining wall . i.e mark "X" 4 1/2" in from the end of the plate with the x back in to the room. another method is to install a "L Stud" at the end of the wall, this creates backing for drywall and it stiffens up the corner so theres no flex

Basement Framing

Just add a 2x6 to the end stud of the 2x4 wall for a "California" corner.

Remember to add a fire-stop to stop fire from going past any gap between top plates into the joist bays above: How to fireblock framing

Use a sill sealer under the p.t. bottom plate for an air/thermal/capillary break:

Add fire blocking every 10’ lineally tight to the concrete wall as per minimum safety code:
Using wood against the walls;

Then add your foamboard if in Zone 4 or higher.

Insulate and air seal the rim joists:

And the drywall:

No gap between insulation:

Going to be one-warm-basement when you are done…..
