R-VALUE

Specialty Definition: R-VALUE

Energy

A unit of thermal resistance used forcomparing insulating values ofdifferent material. It is basically a measure of the effectiveness of insulation instopping heat flow. The higher the R-value number, a material, the greater itsinsulating properties and the slower the heat flow through it. The specific valueneeded to insulate a home depends on climate, type of heating system and otherfactors. (references)
 A measure of the capacity of a material to resist heat transfer. The R-Value is the reciprocal of the conductivity of a material (U-Value). The larger the R-Value of a material, the greater its insulating properties. (references)

Specialty Definition: R-value

(From Wikipedia, the free Encyclopedia)

The R-value is a measure of thermal resistance used in housing insulation. It is defined as R = ft2 F° h / Btu.

For comparison, the SI unit of thermal resistance is R = K.m²/W, and 1 ft² F° h / Btu = approx. 0.1761 K.m²/W.
