Description
Flexible fire-resistant acoustic mastic.
Features and benefits:
- One-part water-based acrylic emulsion that can provide up to five hours' fire resistance when used in construction joints and services in both vertical and horizontal applications.
- When exposed to fire, it reacts to form a highly insulative char that slows down heat transfer, and provides a barrier to fire seal.
- Tested to BS EN 1366-3 & 4, UL 2079 and BS 476-20.
- ETA approved and CE Marked.
- Formulated to be halogen- and solvent-free the FiAM exhibits excellent slump characteristics and has been designed to maintain the sound reduction index of a structure.
- Low VOC.
- Movement capability ±25%.
- Excellent acoustic properties.
- Approved for infinite linear gap length.
- Paintable and excellent slump characteristics.
