Description

Sprayable water-based material, that dries to form a durable, elastomeric firestop coating. This material, when used as part of an assembly, will firestop building joints, perimeter joints (curtain wall), and through penetration seals. Provides up to 4-hour fire protection in construction joints. Gray spray (also available in red), ± 50% movement capabilities.

This firestop spray helps prevent the spread of fire, smoke and noxious gas. In addition, this product acts as an acoustic barrier by minimizing noise transfer (STC-Rating of 56 when tested in a STC 56-rated wall assembly) and meets the intent of LEED VOC environmental guidelines. Note: when tested at 50% movement for 100 cycles in a 4-inch joint, product remained elastomeric and did not show signs of cracking.

The coating complies with the current requirements of the International Building Code (IBC), NFPA 5000 and NFPA 101. It has been fire tested and evaluated for use in construction joints under the pass/fail criteria of ASTM E 1966 (UL 2079), for Perimeter Joints under the pass/fail criteria of ASTM E 2307 and for Through Penetrations under the pass/fail criteria of ASTM E 814 (UL 1479) Standard.

Features

  • Up to 4-hour fire protection in construction joints and up to 2-hour fire protection for through penetration systems
  • Highly elastic material maintains performance with up to ± 50% movement capabilities
  • Superior adhesion to most construction materials
  • Broad range of applications (extensive portfolio of tested and listed construction and perimeter joint systems)
  • Improved spraying pattern - applied with conventional airless spray equipment
  • Paintable
  • Robust jobsite formula (freeze/thaw resistant and uniform seal formation in hot or cold drying conditions)
  • Improved spraying for lower sag, uniform coating build properties (stays where it’s sprayed)
  • Improved hiding power to maintain proper coating thickness
  • Easy water clean up
  • Ideal for firestopping construction joints, perimeter joints, and through penetrations.
