Features and typical uses:

- Self-Levelling silicone

- Water resistant before, during, and after cure Freeze-thaw stable

- Protects your floor openings
- Tested at positive pressure to simulate the pressure differentials that can occur in a fire situation


Self-Seal SL-100 seals service penetrations and expansion joints in fire and smoke rated floor separations.


Basic uses include firestopping:

- Aluminium, pre-cast concrete and curtain wall systems.

- Thermally expanding pipes that are insulated at fire separations.

- Power / communication cables and aluminium / galvanized steel cable trays.

- Static / non-static pipes and conduits.
