You should of course see the manufacturer provided technical data sheet for the r value of specific products. Completely dry growing media the dirt of the green roof so to speak has a minimal r value typically about 0 5 inch.

Increased r value a measure of the resistance of a material to heat flow of the roofing system along with reduced temperatures on the roof lessen hvac loads resulting in energy cost savings. Every construction design architect engineer a e knows a material s r value is an important factor when specifying insulation products with many regulations requiring minimum values for wall ceiling and roof assemblies. Codes may specify a smaller r value for these components compared to the rest of the roof. These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation.

R value of about 2 5 ft f btu. A green roof may improve property values and marketability especially in urban areas with little green space. Determining insulation r value accuracy. Traditional roof green roof n sensible et r q q q substrate 0 where r n net radiation q sensible sensible heat flux due to convection q et.

Neglected thermal storage moisture dependent performance and. For example if you have a type of insulation that has an r value of r 5 per inch of thickness you will need a depth of 6 inches of this insulation installed in your attic to reach r 30 if you live in zones 2 or 3.
