What is Foil Insulation R Value?

What is Foil Insulation R Value? Insulation is measured in R-values.  This is also used to describe the insulating products resistance to transfer heat and how the product will perform as a heat insulator or absorb it. The higher R-value ensures better insulation of heat flowing in or out of the home.  When referring to reflective foil insulation, the R-value measurement relates to the total heat resistance ability of the roof or wall after the insulation is installed.  Radiant heat is often overlooked because r-value does not account for radiant heat. Radiant heat transfers up to 75% of its total heat gain… Read more about What is Foil Insulation R Value? →
