What is Guardian Chimney Liner?

The revolutionary Guardian Chimney Liner® is the safest and most effective system for relining masonry chimneys. Using the cast-in-place technique, the Guardian chimney liner is not just a chimney liner, but also a complete restoration process of the chimney structure.

What does the Guardian Chimney Liner do?

The proprietary formula of the Guardian Chimney Liner® material provides an insulating, refractory compound that is the only chimney liner approved for zero-clearance specifications with 3/4″ liner thickness.

This break-through approval is especially critical when the available flue area will only allow a 3/4″ liner.

Here is how it works:

1. When the area within the chimney is limited, the Guardian 3/4″ minimum liner thickness allows you to line the chimney.
2. Our competitors cannot legally do so, since their minimum poured liner thickness is 1″ to 1 ½”.
3. The Guardian 3/4″ standard ensures all installations will meet zero-clearance specifications.
