To store black fiberglass paper, follow these guidelines: Keep it in a cool, dry place away from direct sunlight and moisture. Ensure the storage area is well-ventilated to prevent the buildup of humidity. Store the paper on flat surfaces to avoid bending or creasing. Use protective coverings like plastic sheets to shield the paper from dust and contaminants. If stacking, do not overload as it may cause the bottom layers to compress and damage. Label the storage area clearly to indicate the contents and check regularly for any signs of deterioration.
