What happens here

Once your required R-value is determined (e.g., R49 as mentioned in the video), consult the 'Buyers Guide' or equivalent chart found on the packaging of your loose-fill insulation. This chart will list various R-values and the corresponding depths (in inches) to which the material should be blown to achieve that thermal resistance. For example, the video points to a chart showing that an R49 rating requires a maximum depth of 17 inches of this specific insulation material.

Goal: Use the R-value chart provided on the insulation product packaging to calculate the precise thickness of loose-fill material needed to achieve your target R-value.

foreign so here's a story about the R rating I'll put a little graph here based off which part of country you live in it'll tell you which kind of insulation you'll need based off of this material that I'm using again r19 for r60 there's a handy dandy chart in the back here that'll tell you based off the rating and how thickness you need so we're looking at our 49 and we need a maximum of 17 inches and as you saw we're sitting at 10 because my thick butt has been stomping it all up and down as I'm trying to work up there
