Assess Existing Attic Insulation Thickness

What happens here

Before adding new insulation, carefully measure the existing insulation depth in your attic. This will help you determine how much more material is needed to reach the desired R-value and thickness. The video implies this step by stating the current insulation is at 10 inches, while the target for R49 is 17 inches, highlighting a deficit that needs to be addressed. Note that existing insulation can become compressed over time, reducing its effective R-value, which the video briefly mentions as 'stomping it all up and down'.

Goal: Measure the current depth of insulation in your attic to compare it against the newly calculated required thickness, identifying any deficiencies.
