R-Values, Heat Flow & Chemical Resistance

Because R-values are 1 /conductance (U), doubling the thickness of insulation will not cut heat loss in half.  Rather, there is an exponential decay of heat flow, where the difference between no insulation and one inch (or one cm) of a particular insulation may save 80% of heat loss, while going from one inch to two inches of that insulation saves an additional 9%, and going from 9 inches to ten inches only saves an additional 1%.

Material Safety Data Sheets (MSDS) and specific chemical properties should always be evaluated prior to application.
