Insulation Advice for Old Brick Building

[Janet Taylor]

I just bought a 100 yr old industrial building to convert to apartment studios. The walls are 13” thick, windows are 48”x83” and floor is thick concrete. The building is 48’ x 38’.  I love the look of the original brick and windows. Is there any way to achieve a comfortable environment without covering brick and removing windows? The ceiling is 14 ft high. I’m trying to consider all options for insulation. What have you experienced when working in this situation as far as insulation is concerned?

Thank you,

Janet Taylor
