R value is a false marketing scheme.
Cork flooring insulation r value.
Cork and all building materials included are actually rated on a scientific term called thermal conductivity not r value.
R values of different flooring materials.
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.
All building materials change in value as the temperature humidity and altitudes change.

Cork is the only flooring material with natural thermal insulation ability.
Impact insulation class iic db 51.
Its insulating qualities are due to its composition.
Traditional test for iic rating.
Cork is a natural insulator that prevents heat loss in the winter and obviously heat gains through the floor during the summer.
Does that mean it has an r value.
Insulation r value cork flooring and underlayment.
These r values are a sum meaning this should be the total r value once you add up the entire depth of insulation.
These numbers will vary from material to material.
You say cork spray provides a thermal insulation.
Cork is made up of 14 sided cells with 60 to 100 million cells per cubic inch.
