List of insulation materials
From Wikipedia, the free encyclopedia
(Redirected from Insulating materials)
Template:Short description 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 metre (3 ft 3 in) thickness and sorts by median value of the range. Template:Sticky header
