STORAGE - MEZZANINE FLOORS - FIRE RATING
Mezzanine Accessories Fire
A very common requirement for mezzanine floors of all types –
whether for storage or offices – is the provision of fire
protection to the structure. This is normally specified as either
30 minute or 60 minute protection, both of which can be easily and
economically achieved using readily available products.
Columns can be protected using pre-fabricated cases. These are delivered
to site already cut to length and simply fit around the column with
a snap-together fixing to hold them securely in place. These are
available in galvanised or white finish.
To protect the underside of the floor structure, the simplest option
is to install a suspended ceiling. A number of ceiling grids and
tiles are available which have been specifically developed and tested
to achieve 30 or 60 minute fire protection for mezzanine floors.
A major benefit is that the ceiling also provides an aesthetic appearance
and provides an ideal option where offices are being installed below
Exposed edges of the floor structure can be protected with fire
rated fascia. These use readily available board materials and can
be plain or decorated as required.
Lights and services
Where a fire rated ceiling or fascia is fitted, it is important
to consider the impact of installing lighting and other services.
Any fittings or services which breach the protection barrier need
to be suitable for this use or separately protected. There is a
range of products available to cover and protect such fittings which
can be incorporated into the design.
