I have a 22ft exterior masonary chimney. It is a straight shot with 10in. by 10in. inside diameter terracotta tile. I was looking for a insulated liner. The liner only has to be a 6 inch so I should have plenty of room. Does the rigid draft and clean better compared to the flex? I have looked at the simpson dura liner and magnaflex's insulflex liner. I think the rigid is more expensive but don't mind spending the extra money if it is worth it. Anybody have any thoughts?
Thanks Matt
