Introduction
Floors and ceilings
British Gypsum offers a full range of specifications
from simple plasterboard ceilings through to a
range of gypsum-based, acoustic suspended
ceilings and lay-in grid systems. They cover all
building categories, including private and social
housing, apartments, healthcare, educational
facilities, recreational and industrial properties in
both new-build and refurbishment and can satisfy
the most demanding performance requirements.
Floors and ceilings
When specifying floor and ceiling solutions, a number of
performance characteristics are normally used to determine the
required solution. Depending on the project or construction type,
these performance parameters could be set by minimum regulatory
standards, or a client or customer requirement, for buildings that
offer the highest standards of performance and comfort.

Our quick-reference floors and ceilings system guide, below, allows
you to simply select the performance categories of interest and
identify the British Gypsum floor and ceiling systems which best
satisfy your project requirements.

Definition of traditional buildings.
A building or part of a building of a type constructed before or around 1919:
a) using construction techniques that were commonly in use before 1919; and
b) with permeable components, in a way that promotes the dissipation of moisture from the building fabric.

Good practice specification guidance
British Gypsum’s systems are designed and tested to meet
every performance requirement and are fully supported by
our SpecSure® lifetime system warranty.
This means that when our systems are installed following
our guidance they will achieve every performance claim we
make, and if they don’t then we’ll put it right. To maximise
the performance achieved on site, consider the following
good practice specification guidance:
— Consider flanking transmission at the design stage and
ensure construction detailing is specified to eliminate,
or at least to minimise, any downgrading of the acoustic
performance. The sound insulation values quoted in
system performance tables are laboratory values and
the practicalities of construction will mean that acoustic
performances measured in the laboratory will be difficult
to achieve on site
C06. S01. P03
—Small openings such as gaps, cracks or holes will conduct
airborne sounds and can significantly reduce the sound
insulation of a construction. For optimum sound
insulation a construction must be airtight
—When designing spaces requiring separation by sound insulating floors and ceilings abutting structural steelwork, consideration should be given to the potential loss of sound insulation performance through the steelwork

Cavity fire barriers
Regulatory requirements demand that cavities
and concealed spaces, in the structure or fabric
of a building, are sub-divided or sealed by means
of cavity barriers or fire-stopping to restrict the
hidden spread of smoke and flames. This is of
prime importance since many buildings are
honeycombed with concealed cavities and voids
within the roofs, floors, and walls.

Key benefits
—Cavity barrier performance options to match partition performances up to 60 minutes fire resistance
Floors and ceilings
—Fire separation is maintained throughout the life of the building due to the board lining being mechanically fixed
—High level of component commonality with GypWall partition systems

The fire resistance and sound insulation performances are for imperforate partitions, with all joints taped and filled, or skimmed according to
British Gypsum’s recommendations. The quoted performances are achieved only if British Gypsum and Saint-Gobain Isover components are used throughout, and
the Company’s fixing recommendations are strictly observed. Any variation in the specifications should be checked with British Gypsum.

Planning – key factors
Important information
The maximum distance between barriers must be appropriate to
the location of each cavity. Also, due consideration must be given to
the class of surface exposed within the cavity.
It is also important that smoke and flames are restricted from
passing from any cavity in a building element directly into a room or
another cavity. Therefore, a cavity must be closed by a cavity barrier
at every junction with another cavity. Any cavity contained within
an element is also required to be closed by a cavity barrier around
the perimeter of any opening through the element. The closure
of cavities may already be provided by the construction itself, e.g.
where a British Gypsum partition system prevents the continuation
of cavities at a ‘T’ junction.
Fixings through the cavity barrier
framework into the structural soffit must
be capable of supporting the weight of
the entire cavity barrier construction.
British Gypsum ceiling solutions are not
intended to provide any support to the
cavity barrier.
Fire stopping
Smoke and flames must also be restricted from by-passing any
building elements that are required to have fire resistance. Any
cavity crossing the edges or ends of a fire resistant element should
have a cavity barrier provided in the same plane as the element,
refer to construction details 3 - 5. There are certain exceptions to
this requirement, such as cavities in floors and roofs where the
ceilings provide a minimum of 30 minutes fire resistance in addition
A cavity barrier must be tightly fitted to a rigid construction,
or, if it abuts against slates, tiles, corrugated sheeting, or other
construction to which it cannot be so fitted, then it must be suitably
fire-stopped at the junction. Refer to construction details 1 - 2,
which show fire-stopping solutions using stone mineral wool.

fire-stopped using suitable materials, shown by test to maintain the
fire resistance within that construction.

Floors and ceilings
Cavity barriers must maintain their performance during the life of a
building, taking account of any possible building movement due to
subsidence, shrinkage, or thermal change. In addition, the possible
failure of its fixings or adjacent construction in the event of a fire,
and the collapse in a fire of any permitted services penetrating the
cavity barrier, should be considered.
