Chimneys can be constructed within a windshield. The structure has a reduced overturning moment when compared to a similar arrangement using a single post or open framed mast, and would therfore require smaller foundations. On site erection time for such a structure can often be considerably less than that required for a mast, particulary if the shell section flanges are internally located, which reduces the need for external scaffolding.

As the chimneys are enclosed within the windsheild, and the assembly often features internal "landings", the facility of easy inspection and access for maintenance of the entire structure is considerably reduced. However, appearances are very subjective, and the overall design features of the windshield would in some cases not be considered as aesthetically acceptable.
