What "R-value" Really Means?

R-value is a measure of resistance to heat flow through a given thickness of material. In theory, the higher the R-value, the greater the resistance. That’s true to a point, but it’s just one of four key factors that determine the effectiveness of an insulation material.

R-Value Formula is just 1 of 4 indicators of insulation effectiveness

Insulation is, first and foremost, meant to stop the movement of heat. The problem with using R-Value as the sole yardstick of an insulation’s effectiveness is that heat moves in and out of a home (or any building) in four ways: conduction (which R-Value measures), and by convection, radiation and air infiltration (none of which R-Value measures). Cellulose insulation offers high R-Value while also controlling these other three important insulation factors. To learn more switch to the full site view.
