Strange Brick-Insulation Detail.....Euro Method?
Strange Brick-Insulation Detail.....Euro Method?
(OP)
I have a prospective client from Germany who wants to do a detail I am unfamiliar with in the States. He says they buildA photo is attached showing the concept. Basically your veneer stands proud of the structure, as much as 6". This 6" void is filled with fiberglass insulation. The veneer is tied back with a system of periodically spaced masonry ties. The problems with this that jump to my mind are:
- buckling of the ties under compression (direct wind)
- seismic loads on the veneer would make the entire tie system try to pancake as the veneer sways back and forth parallel to the wall
- squishy......the insulation has zero compressive resistance. Perhaps if it was rigid foam? Or if we had ties with compression ability?
This is just a strange detail to me, and I'll admit that part of that is because I have never seen it before. Any input from people who have used this or had success (or failure) with this would be great.

Please note that your photo also does not show a vapor/moisture barrier (or air barrier if a large commercial project). And i would never use those ties, they look bad... Basically that photo is illustrating an example; but in my opinion is a very poor design.
Remember brick is a poor weather barrier, it is porous, it will leak, it will crack, and it is heavy. But it does look nice! So i guess at 40psf leaking whats the problem :)

I have done wall cavities up to 6" but they are hard. Anything over 4" cavity causes headaches with fixed lintels and shelves. And you can typically get a good R value with spray foam/board
