How frequently are furring strips placed on center in older homes?

In older homes, furring strips are typically placed on center at intervals of 16 inches. However, in some cases, additional configurations can lead to spacing occurring at either 12-inch or 24-inch intervals due to various building practices.

Given the options, the choice of 6 inches reflects a less common practice, primarily because such close spacing would not serve any structural purpose and is not characteristic of standard practices in older construction. The 12-inch spacing is more plausible as it could be a method to provide more support for various finishes or insulation in some specific scenarios.

However, the other options—8 inches and 10 inches—are not typical measurements used in the construction standards related to furring strips, which usually aim to balance structural integrity with ease of installation in the context of wall sheathing or finishes. Thus, while these options may have some validity in different contexts or newer construction techniques, they do not align with the more established practices seen in older homes.

Ultimately, while 6 inches is selected as an option and may have certain niche applications, it's important to note that in standard construction practices, especially in older homes, the intervals for furring strips differ significantly from 12, 8, and 10 inches, positioning
