R-value – jak badamy ten parametr. Z technicznego punktu widzenia R-value określa stopień izolacji cieplnej. Wyższa wartość R-value oznacza dla danego materiału lepsze własności izolacyjne (rezystancję termiczną).
The range of R-values of insulation materials spans from materials with R-10 insulation values per inch like vacuum insulated panels and silica aerosol to below R-1 values per inch like bricks, glass, and poured concrete.
We will look into what does R-value means, how it is calculated, what are the minimum recommended values of R for attics, 2×4 and 2×6 walls, and so on (you will find a complete insulation R-value chart further on), and what it’s so important to pick building materials with high R-values.

The R-value is a measure of an insulation sample's ability to reduce the rate of heat flow under specified test conditions. The primary mode of heat transfer impeded by insulation is conduction, but insulation also reduces heat loss by all three heat transfer modes: conduction, convection, and radiation.
