Fire and ceilings intersect in two different ways, and confusing them leads to mis-specification. The first is reaction to fire (how the material itself behaves); the second is fire resistance (how long a system holds back a fire).
Reaction to fire
This rates whether a product is combustible and how it contributes to a fire. Mineral ceiling tiles are typically non-combustible (Euroclass A1/A2), making them a safe default for most occupied buildings.
Fire resistance & independent systems
Some ceilings are tested as part of a floor/roof assembly; others are independent fire protection systems that provide a certified fire-resistant membrane on their own. These are specified where the ceiling must protect the structure or compartment for a defined period.
How to specify safely
- Confirm the reaction-to-fire class (aim for non-combustible mineral tiles).
- Where fire resistance is required, use a tested, certified system — not just a tile.
- Check the certification covers your exact tile + grid combination.
- Keep documentation (e.g., declarations of performance) for compliance.
OWA offers both non-combustible mineral tiles and dedicated independent fire-protection ceiling systems, so fire requirements can be met within one product family.
Frequently Asked Questions
Are ceiling tiles fire resistant?
Most mineral ceiling tiles are non-combustible (high reaction-to-fire class), but true fire resistance — holding back fire for a rated time — requires a tested, certified ceiling system.
What is an independent fire protection ceiling?
It is a ceiling system certified to provide fire resistance on its own, protecting the structure or compartment for a defined period, independent of the floor above.
What fire class are mineral ceiling tiles?
Mineral ceiling tiles are typically Euroclass A1 or A2 — non-combustible — making them suitable for most occupied and public buildings.
