Handling and storage
Modified bitumen membranes are to be stored on pallets in a dry and cool place. Use a plastic hood or tarpaulin for protection. When the outdoor temperature exceeds +40°C, the rolls must be protected from sunlight.
Before installation, the rolls must be stored at a temperature of +15 °C, or warmer, for at least a day. The membrane rolls are unrolled in advance to straighten
out, which prevents bumps in the product. The time that the straightening out requires depends on the temperature (approximately 1 to 4 hours).
