Sodium silicate-based fireproof intumescent grilles

FIRE GRILLES PRODUCT INTRODUCTION

Function
Fire Grilles are designed to:

• Allow free airflow through building components (walls, doors, ducts) at room temperature

• Automatically expand when exposed to fire-induced heat (typically ≥100°C/212°F)

• Prevent cross-compartment spread of flames, smoke, and toxic gases during fires

• Available in rectangular and circular configurations

Key Features
• Thermal Activation – Begins reaction at 100°C (212°F) ambient temperature
• Rapid Closure – Achieves full seal within 5 minutes of heat exposure*
• Advanced Construction – Features sodium silicate-filled thermoplastic casing with intumescent properties
• Easy Installation – Pre-drilled mounting points with universal bracket compatibility
• Application Scope – For interior use only (non-weatherproof design)

*Actual closure time varies based on heat intensity and installation conditions

Typical Applications
✓ Fire-rated door assemblies
✓ Firewall penetrations
✓ Fire barrier partitions
✓ Ductwork through compartment walls
✓ Smoke control zone separations
