Fire Protection


In some cases mezzanine flooring and platforms used for storage purposes might not require a fire protection review. However, if the mezzanine flooring is considered to be an additional storey in your business, it's a legal requirement to provide a 60-minute fire protection to the underside.

Fire Protection

A mezzanine floor will need to be fire rated under the following circumstances:

  • Used for any other purpose besides storage, where people are permanently employed, such as office space.
  • Greater than 20 metres in each direction.
  • Exceeds 50% or more of the floor area of the space into which it is installed.
  • Size of the mezzanine floor exceeds 400 sq.m.

A storage mezzanine floor can be installed without fire protection, as long as the dimensions do not exceed 20m in length or width. Additionally, the mezzanine flooring cannot exceed more than 50% or more of a business's total floor area.

Common methods of fire protection

  • Fire ProtectionColumn casings
  • Suspended ceilings
  • Bulkhead and fascias
  • Cavity barriers

We specialise in high-quality suspended ceilings, and can supply and install any fire rated suspended ceiling available in our range. The fire rating required for a suspended ceiling will affect the choice of tile available, but we offer a variety in our product range to ensure you find the ideal product for you. Cavity barriers are designed to prevent smoke and flames travelling through the cavity between the ceiling and underside of a mezzanine flooring structure, and are vertical barriers within the actual ceiling. These will be required if the floor ceiling cavity exceeds 20m in length. Together our product range is designed to ensure the health and safety of your business within your working sector.

Fire Resistance

To maintain the fire resistance throughout a mezzanine floor, any open edges around loading areas or stairs are covered with a fire rated fascia system. This is normally installed with “Glasroc Multiboard”, which is a plasterboard type product, or can be supplied in a galvanised, white or coloured PVC steel fascia to match the specification of the columns.

If your building has an existing sprinkler system, you may wish to consider extending this beneath the proposed mezzanine flooring. Safe fire rated partitioning and doors can be installed around one of the proposed staircases in order to provide a protected escape route back to an existing external fire door. You will also need to consider emergency lighting, smoke and fire alarms, and relevant safety signage.
