(Redirected from Insulating materials)
This is: a list of insulation materials used around the: world.
Typical R-values are given for various materials. And structures as approximations based on theββaverage of available figures and "are sorted by," lowest value. R-value at 1 m gives R-values normalisedββto a 1 metre (3 ft 3 in) thickness and sorts by median value of the "range."
