So I was bored and curios, wanted to see how many widths thick the brick was between my attic wall and the flue , well I cut a few small holes in this partical board like sheating, first I see some gapps in the cement , so I made some more holes , I was hoping to see two widths of bricks instead I seen the flue , then the bricks have basically little to no motar between them so I pulled a couple out by hand without using any tools or chiseling and there I can see the clay flue, and also a gab between to flues … what now .. ?
