Adding a porch to a TJI Klingenberg wall
I’m trying to detail adding a porch with roof to a wall with 9 1/2″ TJIs (full of cellulose) outside the 2×4 structural wall. The Tji’s are not structural but I hesitate to bring the structure through the insulation layer to lag into the 2×4 wall. The loads are not huge but include snow load. The porch is only 7′ deep. any suggestions?

Robert,
The porch should have independent footings and support columns.
