What potential issue can arise when applying loose fill insulation in an attic framed at 24 inches on center?

When applying loose fill insulation in an attic with framing at 24 inches on center, the potential issue that can arise is insufficient insulation coverage. Loose fill insulation is typically designed to be poured or blown in and requires careful installation to ensure an even and adequate layer across the attic floor.

When framing is spaced further apart, like 24 inches on center, the insulation can settle or not adequately cover all areas between the joists. This can lead to gaps or inconsistencies in insulation, resulting in decreased thermal performance and potential energy loss. Proper installation techniques, including knowing the appropriate depth and ensuring complete coverage, are critical in this scenario to maximize efficiency and avoid cold spots due to insufficient insulation.

The concern regarding extra weight is less significant as loose fill insulation is lightweight. Increased air leaks may occur due to improper sealing of the space rather than the distance of the framing. Fire hazard is generally more associated with the type of insulation material used and the interactions with heat sources rather than the framing distance. In the context of loose fill installation, ensuring adequate coverage remains the primary concern.
