Which item is NOT typically a part of masonry accessories in an estimate?

In the context of masonry estimating, masonry accessories refer to items that are necessary for the installation and performance of masonry work but are not part of the primary masonry units themselves. Control joints, lintels, and sills are all integral components that facilitate proper construction, ensuring structural integrity and accommodating movement in masonry walls.

Control joints are included to allow for expansion and contraction of the masonry, helping to prevent cracking. Lintels are structural elements that support the load above openings, while sills provide a finished edge at the base of windows and provide support and water shedding to prevent moisture intrusion.

Heating equipment, on the other hand, is not a masonry accessory but rather a tool or system used in the construction process for curing or drying purposes. It doesn't directly contribute to the structural or functional aspects of masonry assembly and thus does not belong in a list of masonry accessories in an estimate.
