- Note to Reader
- Liquid membrane flashing systems are manufactured from various bituminous and non-bituminous materials. These manufactured proprietary flashing systems are specifically designed for use to flash unusual roof penetration shapes or roof details that are difficult to flash with traditional membranes.
- Liquid membrane flashings are available as one or two part component systems that require reinforcement scrims for strength. To ensure quality installation, manufacturers’ proprietary application instructions must be strictly followed.
- 2-Part Component Systems
- For use with fabric reinforcement only (refer to product Technical Data Sheet for proprietary reinforcement materials). These systems may be used on or within 200 mm (8") of the water plane.
