List of insulation materials

none

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 the average of available figures and are sorted by lowest value.* R-value at 1 m* gives R-values normalised to a 1 m thickness and sorts by median value of the range.
