Sound absorbing solutions

British Gypsum sound absorbing solutions, incorporating Gyptone, Rigitone and Gyprex tiles, boards and planks, combine exciting aesthetic design with excellent acoustic absorption performance.

With performance levels up to Class A sound absorption, our ceilings meet the demands of industry standards in sectors such as education, healthcare and residential, making them ideal for schools, high-rise multi-occupancy buildings, healthcare buildings as well as offices and retail premises.

Our quick reference sound absorbing solutions guide, below, allows you to understand the key benefits of each solution, including grid concealment and flange size. Further detail can be found within the subsequent sections to help further refine your choice.

Sound absorbing solutions

Areas to consider when specifying

Acoustics

A suspended ceiling can provide two levels of acoustic performance;

sound insulation, preventing the passage of sound into the room

from an external source, and sound absorption, which is the control

of undesirable sound within the room, in the form of reverberation.

Ceiling systems incorporating products such as Gyproc SoundBloc

provide the greatest level of sound insulation, while the Gyptone or

Rigitone ranges provide excellent sound absorption performance for

reverberation control.

Aesthetics

The ceiling provides a large blank canvas which can form part of the

overall interior design scheme. Patterns, colours and shape can all

be easily incorporated using products such as Gyptone or Rigitone.

A lower key, minimalist appearance can be achieved with the clean,

white finish of Gyprex systems.

Air quality

Historically, the role of a suspended ceiling has been limited to

passive performance in terms of aesthetics, acoustics and fire

resistance. With our VOC-absorbing ACTIVair technology now

available as standard in all Gyptone and Rigitone products, the

ceiling can now take on a more active functional role within the

room. It actively improves the indoor air quality and provides the

associated benefits to the occupants in the space below.

Refer to C02. S01. P49 – Indoor air quality.

Accessibility

Whatever type of ceiling is designed (table 1), access to the cavity

above the ceiling will inevitably be required. whether this is for

inspection, maintenance or repair of HVAC and similar services.

A seamless system such as CasoLine mf can accommodate access

points in the form of Profilex or Gyptone access hatches, whilst

lay-in grid ceilings have the advantage of allowing access at

virtually any point across the ceiling.

Types of ceiling

Demountable

A traditional demountable ceiling consists of individual ceiling tiles

which are laid into a metal grid. More recent innovations of the

traditional lay-in grid ceiling include the CasoLine quick-lock-grid

Corridor System. The plank system can be used to provide totally

clear, unobstructed access to M&E services in commercial buildings.

Lay-in ceilings are generally simple to install, easy to maintain and

can be dismantled, repositioned or even reused.

Seamless

Systems such as CasoLine mf or GypLyner universal ceilings provide

a smooth, seamless monolithic ceiling. These types of ceiling can

be used to achieve high levels of sound insulation, absorption, or

both. These systems provide a large degree of flexibility and can be

installed horizontally, sloped, vertically or - using CasoLine curve -

giving a contoured shape.

Cleanability

Commercial ceilings are subject to a diverse range of cleaning

regimes. A hospital ceiling, needs to cope with the frequent and/

or aggressive cleaning regimes required in clinical areas. Ceiling

systems such as Gyprex bio provide a wipeable vinyl surface with

an integral biocide, preventing the growth of fungi and bacteria,

including MRSA, E. coli O157 and Salmonella.

Additional Information

Our Gyptone range offers the highest level of accessibility to the

ceiling cavity. Gyptone Hatch, Gyptone Plank and the Gyptone TRAP

system are ideally suited to where regular or unrestricted access

to the cavity is required and can be used either as a stand-alone

solution or in conjunction with another Gyptone ceiling.

For full details of these products and suitable systems, please refer

to the British Gypsum Ceilings Installation Guide, available to

download from british-gypsum.com.

CasoLine quick-lock Corridor System

The CasoLine quick-lock Corridor System provides the ideal solution for corridor ceilings. It combines the aesthetics and sound absorption qualities of Gyptone Plank with easy access to services concealed within its plenum. It is quick and simple to install, and provides a demountable system that is easy to remove, replace and even reposition if required.

Key benefits

— Gyptone Plank and CasoLine quick-lock can be easily removed by hand, providing total uninterrupted access to the services above for future maintenance

— Suspended ceilings are usually prone to damage in frequently accessed service areas as they cannot normally be easily removed. CasoLine quick-lock Corridor System provides easy access to plenum services within corridors, through a completely unsuspended grid that can span up to 2.4m

— There is no requirement to install hangers or soffit supports for spans 2.4m or less (1.8m if insulation laid on back); making setting out, installation and removal much easier

Building design

CasoLine quick-lock Corridor System is a metal grid system

comprising CasoLine quick-lock Main Tees and Shadowline

Mouldings CLSM04 into which Gyptone Plank can be installed.

Planning - key factors

Gyptone planks must not be loaded. Light fittings and other fixtures

should be independently supported. If Isover Acoustic Partition Roll

(APR 1200) is placed above the ceiling, the maximum

self-supporting distance is reduced to 1800mm. Hangers should be

used for increased spans.

Refer to construction detail 1.

Cavity barriers

Where cavity barriers are required, they can be formed using

Gyproc FireLine or Glasroc F multiboard screw-fixed to a simple frame.

The framing should be fixed to the structure to avoid undue loading

of the ceiling suspension grid. The bottom of the framework should

be fixed to the ceiling grid.

Refer to C06. S07. P02 – Cavity barriers.

Services

The ceiling void above the CasoLine quick-lock Corridor System

can be used to route all service requirements, including ducting,

pipework, electrical cables, and conduits. All services must be

independently supported from the structure.

Maintenance

Gyptone Plank can be cleaned using a damp cloth or soft brush.

Most standard mild detergents can be used. Gyptone Plank can be

re-decorated if required using a suitable emulsion paint and a

short-haired brush or roller (spray painting will impair sound

absorption).

Gyptone tiles with ACTIVair

Though we don’t notice them, impurities, such as Volatile Organic

Compounds (VOCs) including formaldehyde, are often present in

the air we breathe - emitted from furniture, carpets and building

materials. Long-term exposure to these can potentially cause health

problems and reduce general wellbeing. Studies have shown that

clean air, can speed up patient recovery in hospitals, reduce absence

at work, and increase pupils’ concentration at school.

ACTIVair is our latest technology designed specifically to convert

formaldehyde emissions into non-harmful inert compounds. Tests

show that ACTIVair decomposes 70% of the formaldehyde in a

controlled test environment. This clever technology continues to

work for over 50 years, and whilst alternative solutions absorb

formaldehyde, they don’t decompose them like ACTIVair, risking

re-emission at a later date.

CasoLine quick-lock Corridor System installation overview

Additional information

For full installation details, refer to the British Gypsum Ceiling Installation Guide, available to download from british-gypsum.com

CasoLine quick-lock grid Shadowline

Moulding CLSM04 is fixed to the wall at

300mm centres.

CasoLine quick-lock grid Main Tee CLT15P

sections are cut to suit the width of the

corridor. The section length should be no

more than 10mm shorter than the corridor

width. Main Tee sections are fitted into

the CasoLine quick-lock grid Shadowline

Moulding CLSM04, onto the upper recessed

flange. There is no requirement to install

hangers to support the CasoLine quick-lock

grid Main Tee sections. These sections

should not be joined and no soffit supports

or hangers are required.

Gyptone Planks are cut to fit on the lower

flange of the CasoLine quick-lock grid

Shadowline Moulding CLSM04.

This is intended to be a basic description of how the system is built.

For detailed installation guidance refer to the British Gypsum Ceiling installation guide.
