Fire ratings for tiles

Q. Are ceramic and porcelain tiles non-combustible?

Yes. Ceramic and porcelain tiles are made from inert, mineral-based materials and are fired at temperatures exceeding 1200°C, making them non-combustible. They do not ignite, burn, or contribute fuel to a fire.

Under NCC Volume One, Clause C1.10 – Fire Hazard Properties, item (c)(i), ceramic tiles (and similar materials such as concrete or terrazzo) are exempt from fire hazard property testing. This means that tiles are deemed to satisfy the fire hazard requirements for internal linings, wall and ceiling finishes, and floor coverings.

Q. Do tiles need a fire rating or fire hazard test?

No. Because tiles fall under the NCC exemption for non-combustible materials, they are not required to undergo separate fire hazard testing for:

  • Flame propagation
  • Smoke development
  • Heat-release characteristics

This exemption applies specifically to the tile material itself.

Q. Do tile adhesives and grouts comply with fire requirements?

Most cement-based adhesives and grouts are non-combustible once cured and are suitable for use with tiles in areas where non-combustible materials are required.


However, adhesives and grouts are not part of the NCC’s deemed-to-satisfy exemption, and compliance should be confirmed via each product’s Technical Data Sheet (TDS).

Q. Can tiles be installed near fireplaces, cooktops, or heat sources?

Yes. Tiles are stable under high temperatures and will not warp, melt, or ignite. They are commonly used:

  • Around fireplaces
  • Behind cooktops (as splashbacks)
  • In outdoor kitchen and BBQ areas

Important: While the tile surface is non-combustible, the substrate behind the tile must also comply with NCC requirements for installation near heat sources.

Q. Do ceramic or porcelain tiles produce smoke or toxic fumes in a fire?

No. Tiles are inorganic and do not release smoke, toxic gases, or combustible fumes when exposed to fire or high heat.

Q. Do tiles provide a fire-resistance level (FRL)?

No. Tiles do not provide a structural fire-resistance level on their own.
FRL requirements apply to walls, floors, and structural building elements, not surface finishes. While tiles can be installed on FRL-rated walls or floors, they do not increase the FRL of the substrate.
