material in the required non-combustible zone and the
non-combustible finishing material over that, remove the
template.
• A bead of non-combustible sealant (or Super Calstick)
must be used to close off any gaps at the top and sides
between the fireplace and non-combustible facing
(Figure 7.6) to prevent cold air leaks and the risk of fire.
Large gaps can be bridged with fiberglass rope gasket.
