What Is the House Insulation Has the Best R Rating

What is the R Value?

An R-value is a rating which measures how well insulation tin resist heat flow. 'R' stands for thermal resistance. The R value depends on the blazon of fabric, its density and thickness.

Tiny air particles trapped in the insulating material resist the movement of estrus (and common cold). The college the R value, the better the insulation is at reducing heat flow.  This means, for instance, that R2.half dozen insulation is more effective than R1.half-dozen insulation.
