Armstrong’s CPD presentation entitled ‘A Better Learning Environment’ is RIBA accredited CPD material.
Education – the future for a generationThe Government's confirmation of its commitment to the Primary
Capital Programme further extends the scope of the improvements
to the school infrastructure, carrying on from initiatives such as the
Academies and BSF programmes for secondary schools in
England and the Scottish Executive’s school estate programme in
Scotland.
As the global market leader in suspended ceiling solutions,
Armstrong has the products and experience to provide the
expertise to help create a better learning environment within
education premises.
Sound adviceIt has been recognised that to enhance academic achievement in
schools, the provision of correct acoustic conditions is a critical
factor. In England and Wales, the acoustic performance of schools
is now covered by Building Regulations and Approved Document E
recommends that the guidance given in Building Bulletin 93
(BB93) is followed. The BB93 guidelines are also being benchmarked
as best practice in other countries in the UK, and Ireland.
BB93 aims to facilitate clear communication of speech between
teacher and student, and between students, without interfering
with study activities by setting performance standards for:
• Reverberation in teaching and study spaces
• Sound absorption in corridors, entrance halls & stairwells
• Indoor ambient noise levels
• Airborne and impact sound insulation
• Speech intelligibility in open plan spaces
A Better LearningEnvironmentA.B.L.E. (A Better Learning Environment) is Armstrong’s response
to the challenges of modern school design as a result of the
changes in the way education is being delivered today.
It is the consideration of both passive and active acoustic
treatments in generating optimum acoustic conditions for learning.
Control of reverberation and sound insulation using acoustic ceiling
tiles is reinforced by a Sound Field system to create an even sound
pressure level within the classroom and improve intelligibility for all
students.

3 Key Points for GoodAcousticsThe acoustic quality of a room is governed by 3 important practical
criteria...
INTELLIGIBILITY: For effective learning and communi-
cation the speaker needs to be heard clearly at normal
volume without difficulty or stress, no matter where they
are in the room. The correct reverberation time, neither too long nor
too short, is fundamental in ensuring intelligibility. This is achieved
by having the correct amount of sound absorbing material within
the space for its intended purpose.
CONCENTRATION: Whether at school or at work,
disturbing background noise is undesirable and noisy
areas in particular are not conducive to learning.
Blocking sound between rooms is important in ensuring that pupils
can maintain their concentration on their studies and can also
assist in providing improved intelligibility. The sound reduction
performance of separating elements, which may include ceilings, is
therefore important.
CONFIDENTIALITY: Private conversations should
remain just that. To ensure that teacher/student
confidentiality is maintained, the sound insulation
between spaces needs to be maintained in the same way as it is
for concentration and suitable sound attenuation provided by the
separating elements between spaces.
For concentration and confidentiality within open plan areas, sound
absorption becomes the dominant factor.
Creating ‘A Better LearningEnvironment’Considering passive and active acoustics working in harmony together
within the school environment can create a better learning environment.
Passive acousticsPassive acoustics is concerned with the absorption and blocking of
sound within and between spaces. For educational premises this
means looking at the acoustic criteria established in BB93.
• Control of Reverberation in Teaching SpacesBB93 sets maximum mid-frequency reverberation times (Tmf) fordifferent types of unfurnished and unoccupied rooms withinschools. Ceiling tiles are typically the biggest area of absorptivematerial within a classroom and is therefore instrumental in achie-ving the correct reverberation time. Armstrong recommends a mini-mum of 0.4 seconds to ensure that classrooms do not become tooacoustically dead, especially when occupied by pupils.
For a typical classroom a good Class C absorber, such as Dune Max or Ultima are usually appropriate to provide sufficient absorption for the required reverberation times.
Armstrong can provide reverberation time calculations based onthe Sabine equation. These can be used to help provide guidance onthe predicted acoustic performance of a room depending upon theselected interior finishes.
Sound Absorption in corridors, entrance halls and stairwellsBB93 also requires sound absorption in these areas to help controlnoise level so as not to interfere with teaching and study activitiesin adjacent rooms. A full ceiling of 0.60 αw (or better) within theseareas is the simplest way of meeting this requirement.

• Sound Masking
Active acoustic speakers can be used to provide sound masking to
overcome occupational factors affecting privacy. By lifting the back-
ground noise level you can provide confidentiality within a large
open plan space and mask disturbance noise from other classes
also using the room.
Armstrong’s i-ceilings speakers are flat speakers using NXT based
technology that look exactly like ceiling tiles eliminating visual
clutter in the ceiling. They simply replace a complete ceiling tile
speeding up installation, removing the need for cutting tiles on site
eliminating waste and reducing
the risk of theft or vandalism.
They provide a wider angle of
sound dispersion than conven-
tional cone speakers meaning
less are required.
• Sound Field in Action – Case Study: Wavell School
Wavell School was one of many to have harnessed best practice as
part of the 'Classrooms of the Future' initiative, providing and
testing a new and dynamic vision of how subsequent schools
should be designed. Having all the latest developments in ICT such
as, Teleconferencing, Interactive Whiteboards and Sound Field, their
new futuristic classrooms form a flexible and adaptable teaching aid
that can be used for both school and the broader community.
With the ability to re-organise the space to the needs of the lesson,
knowing that teachers will not be restricted by 'fixed' equipment,
the Sound Field System provides flexibility and practicality in both
traditional and dynamic classrooms. With audio systems being
used on the majority of interactive white boards to transmit multi-
media, Sound Field is simply integrated into the Armstrong Dune
System using the speaker and wireless microphones and receivers.
Armstrong has drawn on its extensive experience in creating
3 acoustic guides which can help create ceiling solutions for
the education sector to deliver clearly-defined levels of acousti-
cal comfort. The 3 guides demonstrate how sound absorption
and sound insulation can be used to fit the end-users needs, to
ensure that an appropriate level of intelligibility, confidentiality,
and concentration can be achieved in each individual space.
The acoustic guides can also be found on Armstrong’s acoustic
mini website…
…this also hosts a number of useful selection tools for those
working in the education sector…
A reverberation simulator to hear what different reverberation
times sound like; an auralisation tool, which allows you to hear
the impact of different finishes within a typical room and its effect
on reverberation time and ambient noise levels.
Project case studies and a ceiling selector are also available to
assist with decisions about the most appropriate materials to use.

We’re Learning – Creating ‘A Better Environment’ Consideration of sustainability and the environment in the construction
of school buildings, and the selection of the materials to be used,
is of growing importance. Green credentials are a major factor
affecting the design of many new school buildings, with all government
funded projects required to attain a ‘good’, ‘excellent’ or ‘exceptional’
BREEAM rating. Armstrong is making significant steps to support
and respond to these important challenges in some key areas…
• UK Manufacturer
Although Armstrong is a global supplier and manufacturer of sus-
pended ceiling products, 3 manufacturing plants are located in the
UK producing mineral fibre tiles, ceiling grid and metal ceiling tiles
(2 in Gateshead, 1 in Stafford). Product manufactured in these
plants accounts for in excess of 80% of all Armstrong ceiling tiles
sold in the UK market. ISO certification to quality, environmental
and safety standards is an integral part of
Armstrong’s core philosophy. Armstrong
European manufacturing plants are not only
ISO 9001 certified for quality assurance, but are
ISO 14001 certified for environmental manage-
ment and many are also OHSAS 18001 certified
for occupational health and safety or are in the
process of achieving this certification.
• BRE Product Environmental Profiling
In 2004, Armstrong commissioned BRE to profile our mineral fibre
ceiling tile and grid systems manufactured in our UK plants in
Gateshead. The 0.16 Ecopoint score achieved, at that time, resulted
in a Green Guide to Specification (3rd edition 2002) ‘A’ Rating –
the best available, and a lower environmental impact that the
generic ‘B’ rating for other mineral and metal suspended ceilings.
BRE’s system of profiling has since been updated, therefore, during
2007 we updated our Environmental Profile using the new methodo-
logy and incorporating changes to our processes and raw material
selection. This has resulted in a 40% reduction of our Ecopoint
rating to 0.10 Ecopoints. However, as the 2008 revision to the
Green Guide to Specification did not include suspended ceilings,
ceilings cannot have a Green Guide rating, which is testament to
the continuing low impact of Armstrong ceilings.
• Recycled Content
Armstrong has long used recycled materials that are derived from
waste streams of other processes and two of our largest ingredients
are waste fibreglass and newspaper. Armstrong has calculated the
recycled content data for all ceiling tiles in accordance with ISO
14021 methodology and the WRAP 'Calculating and declaring
recycled content in construction products' guidelines. This data
highlights the exceptional recycled content level of Armstrong cei-
ling tiles and enables specifiers to select materials with confidence
based upon their recycled content.

• Recycling Schemes
Armstrong offers a free collection programme for loads of
2000m2 +, anywhere in the UK, of used tiles whenever it is
environmentally and economically viable to do so. This now
means that over 98% of all Armstrong ceiling tiles sold in the
UK can be recycled either as part of Armstrong’s Recycling
Scheme or as segregated metal waste as part of the main contractors
site waste management plan.
As part of Armstrong’s ongoing commitment to the environment,
we are currently trialling suspended ceiling tile off-cut recycling to
establish whether this can be implemented in a sustainable way.
• Canopy Solutions for Thermal Mass
One of the options considered on a number of education projects
is the use of an exposed concrete soffit for its thermal mass to pro-
vide passive cooling. While they can help reduce M&E and HVAC
installation and running costs, they can create technical challenges
in the control of reverberation within teaching spaces where the
slab is exposed. Careful consideration is needed on how to meet
the acoustic requirements of BB93.
With the concrete slab exposed, traditional wall to wall ceiling solu-
tions cannot be used without interfering with airflow to the soffit, so
alternative solutions are needed.
Armstrong Canopies are able to provide solutions for these situa-
tions and therefore help to reduce the environmental impact and
improve energy efficiency within school buildings. Armstrong cano-
pies are available in many different materials, forms, sizes and
colours providing striking design opportunities whilst also offering
different acoustic performances to help with the control of reverbe-
ration. Armstrong’s Canopy Acoustic Calculator is a quick and easy
tool to estimate how many canopies you may require.
An alternative to Canopy solutions are applied wall panels.
However, wall mounted solutions present a number of further
considerations due to the often limited height that they are
mounted from the floor. Issues such as durability, the effect on
acoustic performance of anything pinned to the wall panels and
whether sufficient absorption can be provided from wall panels
need careful thought. These will often be supplementary solutions
in addition to canopies for most spaces other than larger halls or
atria. Armstrong Optima Canopies can also be mounted on walls,
to provide solutions where ceiling canopies alone are not sufficient.

Newfield BSF makes sound investment in Armstrong Ceilings
The Sheffield Building Schools for the Future (BSF) programme
is one of the pathfinder schemes in the Governments initiative and
is being delivered by the Local Education Partnership (LEP), a
partnership between Taylor Woodrow (part of VINCI PLC) and
Sheffield City Council. It will ensure the rebuilding, refurbishing
and/or upgrading of ICT provision for all of Sheffield's secondary
schools, including those for pupils with special needs. The full BSF
programme in Sheffield alone is valued at an estimated £400m.
Newfield Secondary School, a comprehensive school for about
1050 pupils between the ages of 11 and 16, is situated in the south
of Sheffield and is co-located with Talbot (a Special Educational
Needs school). As one of the first to open from Sheffield’s BSF
programme, this project has set the benchmark and established
precedents for future school buildings in Sheffield and beyond.
Building Regulations brought with it sweeping changes as to how
we must now design and construct schools. All school buildings
are now subject to detailed design checks and on-site inspection
by building control officers. The aim of BB93 is to provide a simple
but comprehensive guide for everyone involved in the design of
new school buildings.
Section 1 of Building Bulletin 93 describes the 'Specification of
acoustic performance', giving the performance targets for com-
pliance with the Requirement from Part E of the Building
Regulations 2000 (as amended):
'Each room or other space in a school building shall have the
acoustic conditions and the insulation against disturbance by
noise appropriate to its normal use.'
However, despite the fact that school premises are covered by
government legislation to ensure otherwise, many educational
buildings still suffer from poor acoustics. This interferes with the
ability of teachers and pupils to communicate, which in turn can
lead to lack of concentration amongst pupils and impairment of
learning. As the ceiling forms the main uninterrupted surface in
teaching spaces, it is good practice to use this area to provide
the necessary treatments. However, these in turn will vary from
room to room, depending on its function and purpose – for example,
whether it is to be used primarily for speech or for music.

The ceilings were chosen in line with the strict specification from the
architect.
Jane Bareham, of HLM Architects, Sheffield, said “The right kind
of acoustics are crucial in teaching spaces, not only within a
classroom but also to minimise interference from outside corridors,
so pupils are not disturbed during lessons. Armstrong were able to
offer a wide range of ceiling tiles with variable sound absorption
qualities, according to the rooms they were to be used in”.
Armstrong ceilings came in on budget without any compromise in
quality or aesthetic appearance. A variety of materials such as Dune
Max Tegular mineral tiles, Orcal Clip-In 5mm metal tiles and special
customised Madera wood tiles – were chosen for acoustics, cost
and aesthetics respectively.
SCS Ltd, a recognised Armstrong Omega contractor, installed
some 12,000m2 of Armstrong tiles. Roger Lambert of SCS
explained “Armstrong ceiling tiles are easy to install and are perfect
for the education environment due to their robust handling
properties. As a valued Omega ceiling contractor we have vast
experience in working with and installing Armstrong ceiling
products which means we can offer the best service to the
education sector.
The new school opened for pupils in January 2009.
