What is the difference between a TOP-Flex flexible lining system or a TOP-Rigid lining system, and Which one should I use?
TOP-Flex is a flexible one piece liner that can be maneuvered easily through offsets in the chimney. The TOP-Rigid system consists of sections (12, 18, 24, 36, 48) of rigid pipe that are attached together with rivets. Each chimney is unique, if the inside of your chimney has offsets (or turns), a flexible liner will be easier to install. However, if your chimney is short and strait (12 feet or under), a rigid lining system would be an option.
