Storage Conditions

When stored outdoors, the insulation should be stacked on pallets at least 4” (102 mm) above the surface level and protected from exposure to direct sunlight and weather using an opaque, light-colored tarpaulin. Do not use a dark colored tarpaulin. The factory applied packaging is intended only for protection during transit and should only be slit enough to prevent accumulation of condensation then removed prior to immediate use. Insulation that becomes wet or damaged should be removed and replaced with dry insulation.
