Chimney pipe installation
Ok ., question
I cut a hole in our dome and put an insulated chimney pipe through . What’s the best advice on chimneys going through aircrete. ., we sealed it up with Henry’s and some roofing tape . Doesn’t look very tight . What would you do to seal waterproof . Ect
@obo-martin do I need to reinforce the opening I’m wondering if I’ve weakened the structure leaving a hole in it . With just Henry’s sealing it at the moment
@obo-martin Regarding structural integrity, a 10-12 inch round hole should not be a significant structural weakness, assuming your wall thickness is at least 3.5 inches. Circular penetrations have the least structural impact. Read this post describing the impact of earthquakes on raw cut circular openings for windows that were about 4 feet diameter cut into 3.5" thick dome walls.
