Drywall Corner backs

I can see how these clips would increase the R value of the envelope but I would prefer sticking a 2x6 or 8 in there on the flat instead.

I agree, this is a concern.

Doug,

Try this for patch work. This works great for small holes 4 inches square or less. No need for backing and the best part is that the all the material required is scrap anyway.

• Scrap drywall 3 times larger than hole
• Score the back as in photo
• Remove all sections except middle piece, leave the paper on front side
• Apply compound to the perimeter of hole
• Apply drywall and finish

And the finishing touches.

Called a "buffalo patch" Make sure it is feathered out over a large area

I use a couple of 5 gal stir sticks

Drywaller's have referred to it as a "California", "Chicago", and a Toronto patch. Never heard of it referred as a Buffalo patch! That's OK, use what ever name you wish, the application works regardless of what name you give it!

Ive used them for a patch job, when there was no good alternative, but would not even consider them on a new project. They are remarkably strong, but not as strong as wood corners.
