Venting Membrane Storage Protocol
Proper storage conditions are essential to maintain membrane performance characteristics until installation.
Environmental Control
Temperature & Humidity Requirements
- Maintain storage temperature between 15–25°C (59–77°F)
- Keep relative humidity at 40–60%
- Avoid locations with frequent temperature fluctuations
Packaging & Handling
Storage Containment
- Store in original packaging whenever possible
- For repackaging, use airtight opaque containers or polyethylene bags
- Label containers with purchase dates and expiration information
Physical Protection
- Avoid stacking heavy objects on membranes
- Prevent folding or creasing of thin films
- For adhesive-backed variants, ensure release liner integrity
Hazard Prevention
Environmental Hazards
- Protect from direct sunlight (UV degradation)
- Store separately from solvents and corrosive substances
- Keep away from heat sources and ignition points
Critical Note: Condensation inside packaging can occur with temperature fluctuations — avoid storage near heating vents or drafty areas.
Inventory Management
Stock Rotation
- Implement FIFO (First-In-First-Out) system
- Regularly inspect stored membranes for signs of degradation
- Perform quarterly inventory checks for long-term storage
