HELP! I need a straight answer about building a wall.

This. Doesnt mean i will use non treated wood on slabs though. Straight from simpson strong tie website-


Are these alternative products more corrosive than CCA-C?

Testing has indicated that some of the alternative products are more corrosive to steel and some protective coatings applied over steel than Chromated Copper Arsenate (CCA-C). Contact the treated wood chemical supplier for more information and see te Preservative Treated Wood Technical Bulletin (PDF).

 

until they form humps in your wallz

silly carpenters

 

Crowning studs is proper practice

 

Sill gasket

 

Vapor barrier... although if you don't know how the house was built, then the gasket isn't a bad idea. I'd still use PT for the sill though, call it habit.

 

You build crazy custom homes, i would be crowning studs and making sure everything is perfect if i was doing this. I do production framing, the faster the better, i never crown studs. If im framing a wall and the stud is crowned real bad i wont use it.

 

Sill seal and PT

 

vapour

and it doesn't matter , sill gasket under and non treated lumber in contact with concrete

 

Takes the same amount of time , when you pick up the stud sight it and assemble the wall crown up

 

Not a fan

 

Step away for dinner and I get a flood of answers. After reading all the answers here's my plan.

Sill gasket, double top as the floor joists are 20 on center and the wall will be 16, snug but no pressure on the joists especially on the exterior wall, tapcons, framing nails, measure twice and cut once.

 

this

even though no one does it. skills diminishing due to lack of properly trained union labour

 

.... Lol lets not get into that

 

I don't know many people who use union labor for a residential project...

 

labour

 

I was referring to US unions, so labor. You can add your fancy extra U for Canadian labour
