You stop for your morning cup of steaming hot coffee, you hold the cup and it doesn't burn your hands or leak into your lap.... The coffee is about 65°C and the cup is only 3mm thick!!!

Consider that the same cup also protects your hands from icy cold liquids....that's quite an efficient insulator!

Now imagine that the same material that protects your hand from scalding hot and icy cold liquids in a product that is 3, 4, 5 or even 16 times as thick as the coffee cup.....how much heat would that stop?

Add to this reflective facers that stop air, moisture, and vapor infiltration and you have a building product that will not only address heat loss/gain, but will protect against the elements.....An all weather barrier.
