Passive Fire Protection Tiles EI90 fire rated
Product Overview
Fire Protection Tile is a purpose-engineered composite mounting panel developed specifically for inverter and battery installations. Manufactured with stainless steel outer skins and a 27mm aluminium silicate core, FireShield delivers structural rigidity, thermal separation and fire resistance within a single 30mm engineered system. It is designed as installation infrastructure for modern energy systems where safety, compliance and finish matter.
- 27mm aluminium silicate insulating core slows heat transfer to the mounting substrate.
- EI90 fire performance providing 90 minutes Integrity and Insulation when installed within a
compliant system. - Stainless steel outer skins deliver mechanical strength, impact resistance and long-term
durability. - Composite construction resists cracking, edge damage and surface degradation.
- Factory-finished surface provides a clean, professional installation aesthetic.
- Modular 1000mm x 500mm format aligned to modern inverter and battery footprints.
