About Selecting Thermal Insulation

These sheets resist the absorption of water, air, and gas and are widely used in cold-storage and packaging applications.

Polypropylene-coated sheets have an added layer of moisture protection.

Sheets that cannot be sold to the listed regions do not meet chemical regulations.
