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.

• Ambient Background Noise Levels

As with the control of reverberation, providing suitable indoor

ambient noise levels is essential for clear communication and study

activities in the learning environment.

Sources of ambient background noise may be from external

sources outside the school premises or from building services.

Typically the buildings structural elements are the main contributors

to maintaining low ambient noise levels, however, ceilings can limit

service noise from the ceiling void and the absorptive performance

limit the build up of noise within the space. A combination of both

ceiling sound absorption and attenuation can therefore help

control background noise levels.

• Airborne Sound Insulation between Spaces

The level of sound insulation required between spaces depends on

the activity noise from the source room and noise tolerance of the

receiving room. Sound insulation will be typically be provided by the

separating elements, such as slab-to-slab walls rather than to the

underside of a common ceiling.

On top floors it may be difficult in practice to seal the walls to the

roof construction creating possible flanking issues. The use of a

suspended ceiling with a higher sound attenuation performance

can help minimise the effect of this. Armstrong’s dB range of tiles,

such as Perla dB provide higher levels of sound attenuation to help

combat this flanking sound, whilst still maintaining absorption

performance levels to control reverberation.

• Impact Sound Insulation

Typically this is foot fall noise from the floor above. A medium to high

density suspended ceiling with greater sound attenuation performance,

can provide an improvement to the overall impact sound insulation

performance of the floor above.

Impact rain noise on roofs, although excluded from the scope of

indoor ambient noise, can have a significant affect on this, particularly

when lightweight or profiled metal sheet materials are used. With no

damping in the roof construction, higher levels of noise can be

transmitted into the teaching spaces below. As with flanking noise

in the roof space, the use of a suspended ceiling with a higher

sound attenuation performance can help minimise the effect of rain

noise. Perla dB from Armstrong’s dB range is often specified for

these reasons.

• Speech Intelligibility in Open Plan Spaces

Open Plan teaching spaces, where multiple classes are taught in

the same area at the same time create acoustic challenges. They

are significantly more complex acoustic spaces and consideration

of the areas layout and the activity plan is essential. BB93 requires

a minimum Sound Transmission Index (STI) of 0.60 which is consi-

dered ‘good’ intelligibility.

The use of more absorptive ceiling finishes will help to limit sound

propagation between different groups within an open plan area. It

can also assist in the reduction of background noise levels and the

control of reverberation. Armstrong has developed the OP (open

plan) range of Class A absorbing products (≥ 0.90 αw) specifically

for such areas where higher absorption performance is required.

Perla OP and Ultima OP also provide more sound attenuation than

standard lower density high absorption products, which could be

beneficial for improving sound insulation performance.

Armstrong provides a RIBA accredited CPD presentation on passive acoustic concepts entitled ‘Acoustics & Suspended Ceilings’.

Active acoustics Active acoustics uses amplified audio technology through a

loudspeaker network to manage the signal to noise ratio to

complement passive acoustic treatments.

The signal to noise ratio, expressed in dB, is an indication of the

intelligibility at the receiver’s location. By improving the strength of

the signal relative to the noise, intelligibility is improved, and by

covering the signal by increasing the noise, privacy can be improved.

There are three main ways in which active acoustics can be used to

manage the signal to noise ratio.

• Paging / Public Address Systems

A speaker can be linked to a whole school system providing a paging

or public address system to either a specific classroom or through the

whole school. The correct set-up of this system will ensure that the

remote speaker’s voice is heard above the background noise level in

each specific room.

• Sound Field Speech Reinforcement

A Sound Field speech reinforcement system also utilises a speaker

and functions like a mini public address system, but just locally

within that room. An infra-red wireless microphone takes the

teachers voice and the sound reproduced through the speaker and

reinforces the signal towards the rear of the classroom.

This has the effect of creating an even sound pressure level so that

wherever the students are in the classroom, they can hear the

teacher’s voice equally well.

The use of infra-red, rather than radio waves, means that this can

be received by a neck loop to assist hearing impaired students,

making it a truly inclusive technology providing the best acoustic

conditions for learning.

BB93 makes reference to Sound Field and states that the best

place to locate Sound Field speaker(s) is within the ceiling, as

this provides the best sound diffusion to the students. BB93 also

cites the benefits of Sound Field to include academic improvements

in on task behaviour, attentiveness, understanding if instruction,

less repetition required, better attendance, improved measures of

verbal recognition, as well as providing a reduction in teacher vocal

fatigue and sickness.

Acoustic modelling has shown the evenness of the sound pressure

level and the improvement in intelligibility of a typical classroom with

just one i-ceilings Sound Field speaker.

• 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.

Wavell School, Farnborough


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.
