provide reverberation control and improved aesthetics
Introduction
Sound absorbing solutions
British Gypsum sound absorbing solutions,
incorporating Gyptone, Rigitone, Gyprex and
Eurocoustic 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.
A suspended ceiling system, that can be used in conjunction with
Gyptone and Rigitone ceiling boards to create a seamless,
monolithic appearance.

Description
Areas to consider when specifying
Types of ceiling
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,
Rigitone or Eurocoustic ranges provide excellent sound absorption
performance for reverberation control.
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 d1
concealed, and 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.
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 or Eurocoustic systems.
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.
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 the majority of Gyptone 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.
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.

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.
Cleanability
Commercial ceilings are subject to a diverse range of cleaning
regimes. A typical sports hall, for example, may require little or no
cleaning during its working life. A hospital ceiling, on the other
hand, 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.

CasoLine curve comprises Gypframe MF7C Curved Support
Channels, Gypframe MF5 Ceiling Sections and Gypframe MF7
Primary Support Channels.
Planning – key factors
Refer to C08. S03. P04 – Finishes.
Whilst a good quality finish can be achieved using normal jointing
techniques, a plaster skim finish may be considered (with the exception of
Gyptone and Rigitone boards), particularly where there are a number of
butt-end joints on the curve.
Gypframe MF7C Curved Support Channel is supplied pre-formed
to the radius required. Board joints should be avoided on the apex
of the curve for the exposed layer of board. Gypframe MF5 Ceiling
Section positions should therefore be pre-determined at the design
stage.
SpecSure®
All our systems are covered by SpecSure®
when using genuine British Gypsum and
Saint-Gobain Isover products.
Degree of curvature
In common with other sheet materials, board-ends have a tendency
to remain straight, and so the minimum achievable radius will be
influenced by the board characteristics, the length of curve, the
support centres, and the occurrence of board joints.

CasoLine curve installation overview
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.
Gypframe MF6 Perimeter Channel is fixed
at wall positions to the line of the curve.
Timber fillets are installed where required to
pack out the channel.
Suspension for a flat soffit
Gypframe MF12 Soffit Cleats are secured to
the soffit using appropriate fixings.
Gypframe FEA1 Steel Angle hangers are
pre-cut and secured to the soffit cleats.
Pre-formed Gypframe MF7C Curved Support
Channel is installed over the perimeter
channels and secured to the hangers.
Gypframe MF5 Ceiling sections are screw
fixed at right angles to the underside of the
pre-formed support channel to form the
secondary grid, with two British Gypsum
Wafer Head Jack-Point Screws per junction.
For convex curvature, insert a small section
of Gypframe MF7 Primary Support Channel to
provide a flat, positive fixing at the apex. Refer to
construction detail 7.
Boards are fixed to the secondary grid to
form the curvature of the ceiling.
When using Gyptone or Rigitone products please refer to the current British Gypsum Ceiling Installation Guide.
