Partial brick veneer
A question remains regarding insulating the 3/4 brick front (one wythe veneer) of my 1960 ranch in zone 5/6a.
This is a follow up to:
The home is sideways on a narrow portion of the lot. The 3/4 brick front is on the southern exposure, which consists of (from west to east) the family room, a walk-in closet, the kitchen, the main entry door and closet.
Think relentless sun exposure. There is no space to plant shade trees, unless the sidewalk is moved, which isn’t in the budget.
The family room appears to have been an option – the other option was a two-car garage. This room and closet is built on a slab. There are forced air runs in the slab, but no return. The rest of the home sits on a full basement.
There is about 16″ of soffit overhang which somewhat protects the upper part of the brick wall and window/door openings.
The existing wall is:
one layer of brick
two 1/2″ layers of fiberboard as sheathing
kraft faced fiberglass insulation (very, very thin)
The brick seems to be laid on concrete. I could find no weep holes. The mortar is very soft. The bottom row of brick is covered with sand in a one-foot wide strip along the sidewalk.
At the top is an 8″ trim board covered with aluminum trim.
The plan was to dense pack all the walls and add 1.5″ reclaimed polyiso on the non-brick walls, under new vinyl siding.
But what to do here? Will just dense packing the walls behind the brick create a moisture problem? Would spray foam be a better choice here? What other options would you suggest? A dehumidifier in this room?
I’ve been reading whatever I can find here on brick veneer, but it’s difficult to pick out the information that applies to this situation.
Thanks again for your help.
