16. Acoustic overview
Acoustic / Occupant Comfort
A large percentage of a buildings cost
is directly related to its occupation
Essential for productivity in the
workplace
Poor acoustic environment significantly
affects performance
Sound is a series of waves or
pressure fluctuations.
Measured in Hz
Humans can hear between 20Hz –
20,000Hz
Pressure is measured in Decibels (dB)
17. Acoustic Performance -
Absorption
Acoustic absorption
Ability of a surface to absorb sound,
minimising the reflection of sound
energy back into a space
The room characteristic that defines
this feature is “reverberation time”
the length of time (in seconds) that it
takes for a sound source to decay by
60 dB.
Measured
Sound Absorption Rating (αω)
Sound Absorption Class (Class A to E)
Noise Reduction Coefficient (NRC)
18. Acoustic Performance -
Attenuation
Acoustic attenuation
Sound attenuation is used to describe
the reduction in sound between two
spaces separated by a dividing
element, with two basic sound
transmission paths.
Direct sound transmission is the level
of sound passing through the dividing
element I.e. – Relocatable Partitioning
Flanking sound transmission is the
level of sound passing through
surrounding structures
I.e. – Suspended Ceilings
Results measured in dB and
presented as a single figure
19. Acoustic Performance – Ceilings
Buildings need to achieve a balance
and mix of sound absorption and
attenuation products to achieve the
correct results
Absorption
Acoustic fleece - 0.65αω / Class C
Acoustic pad - 0.90αω / Class A
Acoustic pad and steel backing plate -
0.70αω / Class C
Acoustic pad and plasterboard backing -
0.65αω / Class C
Attenuation
Plain tile - 43dB
Acoustic fleece - 13dB
Acoustic pad - 30dB
Acoustic pad and steel backing plate -
48dB
Acoustic pad and plasterboard backing -
49dB
20. The acoustic performance of
partitioning can vary subject to the
specified build
Glass can provide between 32 and
49 dB subject to
Build configuration
Glass type
Cavity size

Partitioning
22. Fire Performance - Ceilings
Requirements for fire performance
Building Regulations, Part B (Fire
Safety)
Metal ceiling tiles tested and certified
in accordance with:
BS 476-23 (also known as Class 0)
EN13501-1
European equivalent for Class O
B-s3,d2
B = Fire behaviour
s3 = Smoke production (no limit)
D2 = droplets debris (no limit)
Metal tiles have a European Class
performance of:
A2-s1,d0
23. Fire Performance - Partitioning
Fire resistant partitions provide a means
of escape or compartmentalise a
building
Approved Document B
BB 100 – Design for fire safety in schools
HTM 56 – Partitions
BS476 Part 20:1987 – Method for
determination of the fire resistance of
elements of construction (Test Methods)
BS476 Part 22:1987 – Methods for
determination of the fire resistance of
elements of non-load bearing elements
of construction
Partitioning is designed to provide
vertical fire separation when exposed to
fire from one side
The Image to the left shows a fire test
after 7 minutes
24. Fire Performance - Partitioning
Fire test procedures measures:
Integrity – The time for the partition to
remain intact
Insulation – The time for the
temperature to rise by 180°C on the
non fire side of the partition
Results are given in time:
30/0 - 30 mins integrity
30/30 - 30 mins integrity, 30 mins
insulation
60/0 - 60 mins integrity
60/30 - 60 mins integrity, 30 mins
insulation
60/60 - 60 mins integrity, 60 mins
insulation
The Image to the left shows the
same fire test after 73 minutes
26. Structural performance -
Partitioning
Categories of Duty relating to
stiffness and robustness of solid
partitioning is defined by BS5234-2:
1992 Annexes A to G
BS5234 is dedicated to internal
partitioning
Atrium glazing is specified to BS6180
(Code of Practice for protective
barriers) and must be applied due to
higher line loading requirements
27. Structural performance -
Partitioning
Testing Procedures
Annex A – Stiffness
Annex B – Small hard body impact
test (surface damage)
Annex C – Resistance to damage by
impact from a large soft body
Annex D – Perforation by small hard
impact
Annex E – Resistance to structural
damage by impact from a large soft
body
Annex F – Door slamming
Annex G – Crowd pressure
28. Ceiling Suspension
Association of Interior Specialists
Guide to selection and installation of
top fixings for suspended ceilings.
Top 4 reasons for ceiling collapse
Incorrect selection of fixing
Incorrect installation of fixing
Additional load applied
Insufficient number of fixings
Guide downloadable from AIS
Website and a 15 minute CPD is also
available
29. Suspension Grid and Hangers
Metal ceilings are suspended by rigid
hangers
Pre punched, avoids snipping and
punching angle or using threaded rod
Reduces installation time
Majority of systems use primary
suspension grids
Improve installed accuracy to meet
building module
Reduces site installation time
Can provide support for additional
loads
30. Service integration - Ceilings
Suspended ceilings need to provide
service integration and accessibility.
Integrated M&E products include:
Luminaires
Speakers
Fire detection and control
Grills / diffusers
Chilled ceiling / chilled beams
Apertures:
Formed during manufacturing
Reduces site waste
Improves site efficiencies
31. Partitioning Deflection
Essential when designing and
installing partitioning systems to
allow for suitable building slab
deflection
Dead and live loads can cause
significant movement in some long-
span floor systems
A live load will almost certainly cause
some degree of movement which
impacts on the space between he
floor and ceiling slab
32. Partitioning Deflection
Range of deflection options
±25mm two part head track
±15mm one part head track
Bespoke deflection option where
greater than ± 25mm is specified
Glass and Drywall integration
Sharing single piece continuous
deflection head across glass and
solid elements
Re-locatable
33. Partitioning - Drywall integration
Seamless integration from glass into
solid
Recessed junctions provide clean
joint
Varying widths of drywall and glass
Performance glass can be specified
34. Partitioning to Ceilings
