Adding a Sliding Door in a Masonry Wall
I am cutting out a wall to install a sliding door on my house. I have discovered, however, that the masonry is not only a veneer but has a lightweight CMU behind it. I have already cut the rough opening, and have the angles for the lintel, but I am curious if I need to add any studs on the sides to nail the door to? Or should I use concrete screws?

Greetings denarch,
This post, in response to your question, will bump the thread through the 'recent discussion' listing again.
Perhaps it will catch someones attention that can help you with advice.

I'll second the famous Razz with a "Welcome!"
The way I learned to install things in masonry walls was to use "bucks," PT (pressure treated) dimensional lumber to make aframe to fasten the door or window to. The bucks would be set to the masonry wall with any number of types of anchors suitable to that job.
The type of anchor will depend on what sort of masonry is there. In new construction we generally want the last cell in block walls filled next to jambs, that way there's something solid to anchor to. In your case, you may need to use an expansion sleeve/shield anchor in the mortar joints.
Now, what sort of buck to install will depend upon the trim for the door, both interior and exterior.
Thanks for your help. I figured on the bucks. I just wanted to avoid having to make the R.O. larger. Live and learn.

LoL, better than learning, then living . . .
When I was "coming up," one of my crusty old bosses always took block back an entire block larger than the RO, jsut so new block could be pointed back in with soild-filled cores with #3 bar up to the brand new CIP lintel.
Completely obvious to all us "young bucks" that this was way too much overkill (and way too much backbreaking labour on our overconfident, gold-bricking, cocksure selves <g>)Occupational hazard of my occupation not being around (sorry Bubba)
