How Thick Is R-38 Insulation? R-38 fiberglass batt insulation is approximately 6 1/4 inches thick, but loose cellulose requires over 12 inches of material to provide the same resistance value. R-values measure the thermal resistance based on the material and its thickness.

R-Value is a measure of insulation’s ability to resist heat traveling through it. The higher the R-Value the better the thermal performance of the insulation. The table below shows what levels of insulation are cost-effective for different climates and locations in the home. Recommended insulation levels for retrofitting existing wood-framed ...
Sustainable Insulation ... The chart shows the R-Value of CertainTeed fiberglass batt, blanket and roll insulation available in the United States. The “R” designation means resistance to heat flow. The higher the R-Value, the greater the insulating power. ... R-Value Thickness Width Length Pieces Sq Ft/Pkg Product Number
R-values, like R-38, are used by the construction industry to describe the thermal resistance of insulation materials, like those used to insulate your attic.When you are looking at an R-38 insulation, you are actually reading a description of its resistance, rather than size or thickness of the material.
R-value is a measurement of thermal resistance and measures the ability of heat to transfer from one side of an object to another. As a benchmark, one inch of solid wood has an R-value of 1. In comparison, an inch of blown fiberglass insulation has an R-value of 3.1 - 3.4 and an inch of blown cellulose in an attic has an R-value of 3.2 - 3.7
R-38 EcoTouch PINK FIBERGLAS Insulation with PureFiber Technology is the preferred Owens Corning insulation by homeowners because of amazing sustainability!
R-30 insulation thickness, or even R-19 thickness is often used in warmer climates. Note that R30 batt insulation thickness is just 9-1/2 inches thick where as R-49 batt insulation thickness is 15-1/2 inches. This is a significant difference and thus why R-49 batt insulation is used typically in colder climates.
