[Greenbuilding] Masonry Caviaty Insulation Detail

[David Wentling]

We built a new warehouse to blend into a historic brick building. Used block wall with base ledge, sealed entire exterior wall with liquid air/vapor barrier. Brick ties extended out between batts of mineral wool. Added 24" high batts as the brick was installed. Batts allow drainage of any moisture in the cavity. Had weep holes along the top of the ledge between first layer of bricks. Fire safe since no plastic!

Do any on the list have suggestions for good insulation details for masonry 
cavity.  I have a local fire company that are expecting their addition to be 
brick veneer on concrete block as is the existing building which;h has 
almost no insulation.  The conventional detail of using either wire trusses 
at 16" or 24" vertical to allow for dimensioned foam to be installed.  It 
strikes me as difficult or not possible to seal rigid insulation at wire 
truss or brick tie.  I considered at one point the installation of a 2x 
furring strip on outside of rigid insulation to provide support for brick 
tie that would not penetrate the foam thermal barrier.  I do not believe 
these clients are particularly motivated to achieve high thermal standard.

Suggestion appreciated.

Eli
