Insulating 140 yr. old balloon framed building w/ brick facade
I am trying to come to grips insulating and air sealing a 3 story 140 yr old brick facade building with wood balloon framing.
The order of materials from the exterior is brick, 2"x5" studs 1' on center, 1" sheathing (widths very from 6" to 30"), vertical lath on top of the studs, horizontal lath (spaced for plaster key ways) and plaster which has been removed. There is no insulation currently in the building and the brick ties are two cut nails tacked into the exterior side of the studs and imbedded in the brick mortar joint.
We are in SW Michigan zone 5, approximately 6,600 hdd, and 34" of precipitation per year.
I am looking for ways to insulate and create an air barrier while keeping the budget from blowing up.
One idea is to remove the lath and sheathing and install rigid insulation between the studs, batt or cellulose to fill the cavity and rigid insulation on the interior of the studs. Some sort of diagonal let in bracing would need to be installed for sheer.
I have not sat down and thoroughly thought this through but would welcome any suggestions.
The homeowner would like to avoid the use of spray foam insulation.
Thanks for your time and response!
