Chimney head walls make themselves

For a trained handyman, it is quite possible to wall a chimney head itself. Please note the building permit requirement and the corresponding drawing in front of the walls. For some projects, a licensed professional must accompany and take over the project.

Transparent or opaque color

The walls of a chimney head are subject to some building regulations. Anyone who has already gained bricklaying experience, for example with a garden wall, can implement the specifications. Without any experience, the chimney head should not be masonry itself.

The principle of alternating runners and trusses must be followed when the chimney head walls. Vertical joints always have to be offset and must not be on top of each other. The interior walls must be smoothly bricked and stone quarters must not be used inside.
