Introduction

Cogent System Panels is essentially an effective system put together by

using a combination of carefully selected building materials to provide a

prefabricated roofing component providing Acoustics and Thermal

Solutions.

Early research works on the Cogent System panels was pioneered by a

roofing contractor specialising in acoustic works in the year 2000.

Confronted with the obvious need to change conventional multifaceted

designs that involved heavy materials making roof top handling very

difficult, working at dangerous heights for longer hours than necessary,

exposure to unpredictable weather ailments including high winds and

irritable conditions caused by fibrous materials, Cogent System panels

were developed and introduced into the market after much research.

The earlier models available then have evolved substantially since they

were first introduced. This was a result of a continuous quest for

improvement and the consistent interaction with both project consultants

and working contractors.

Over the years, many other reputable local and international companies

have joined MISB and contributed effectively in broadening the Cogent

System panels’ compatibility with a wider range of roofing, wall cladding

and other prefabricated systems. Collectively, there is a wide array of test

data available for roof systems to verify the effectiveness of a Cogent

System panel application.

Cogent System Panels have become increasingly popular with roofing

specialists as the prefabricated panels represents simplicity which

reduces laborious site works and installation time.

Adapting with the current labour shortages and soaring workmen costs,

Cogent System panel designs helps to re-think roof construction to

reduce such problems wherever possible.

For project designers, roof designs become increasingly complex with

more performance criteria to fulfil. Our building industry is focused on

embracing responsible measures that would help realised energy

savings, a healthier indoor environment, recycling of valuable resources

and provision of greenery in developments.

Roof designs are also becoming more innovative and architecturally

challenging to form. Cogent System panels provide solutions to various

aspects yet keeping the roof system build up simple at installation.

For property managers, a roof system constructed with a simple build up

makes maintenance works easier.

Cogent Panels are available in standard proprietary models. Standard

models are formulated based upon popular market demands.

For architects and project designers with special requirements,

modifications and enhancements may be made to suit specific project

demands.

MISB’s technical team will be able to assist project consultants in establishing suitable parameters for the projects

intended. This also includes the increasing demands on meeting the Green Building Index (GBI) and/or MS1525:2007 for

energy efficient buildings.

Replacing Conventional Methods

As a general guide, it is commonly understood that achieving higher values of Transmission Sound Loss in a roof

system is directly proportional to mass.

Conventional design methods used in fulfilling this criteria often means very cumbersome construction. Following this rule,

mass will have to be increased by prescribing additional layers of heavy cement boards spaced apart using metal brackets

to accommodate several layers of insulation blankets such as mineral wool or fibre glass laid in between. To obtain higher

STC values such designs would involve much higher structural loading.

Construction Stages

Some projects already have design parameters established based on a conventional system build up.

MISB will be able to assist you in providing alternative value engineered designs using Cogent System panels to maximise

site efficiency for a faster completion, reduce wastage and labour intensity to optimise costs.

Fabrication and Components used in Cogent System Panels

Components used in the manufacturing and fabrication of

Cogent System* panels are carefully selected balancing the

following factors:

Durability

Performance

Stability against variations of weather

Adaptability with other building components

Costs

Weight of Materials

Material Compressive Strengths a

Flexural Strengths

Exoskeleton - HD Shield

The external skin, known as the exoskeleton of the Cogent Panels, consist of a

high density @ density 1300-1350 kg/m3 fibre silicate cementitious board that

are AUTOCLAVED to satisfy the most demanding exposure to weather

conditions.

The composition of the material is 100% free of asbestos manufactured from a

mixture of cement, organic fibres and selected mineral salts. Blended

components give rise to an exterior which has a superb dimensional stability

making it very versatile in both, wet and dry conditions. It is moisture tolerant, fire

resistant to AS 1530 Part 3 as well as BS 476 Part 6 & 7, resistant to industrial

and atmospheric corrosion.

The superior stability of the exoskeleton crust will be able to contribute effectively

towards a shield against weather ailments that are unpredictable during

installation. In the event where if a roof leaks in future, Cogent Panels will simply

dry out and restore its performance.

Internal Framework

EXTRUDED Polystyrene (XPS) Dow Styrofoam* is used for the internal

framework and is adequately strong enough to allow the composite panels to

span with minimum deflection of 1220mm supported at both ends. Dow

Styrofoam* provides high insulation properties which will not allow heat to be

conducted between the composite layers during contact. At the same time, Dow

Styrofoam* has a compressive strength of 300kN/m2 spacing apart 2 particle

boards with an essential air gap which must be maintained over a long term

duration.

While providing the internal rigidity as a framework around the Cogent System

Panels, Styrofoam LB itself is does not absorb water, very light and does not

add additional loads of a roof.

Fibrous and Non Fibrous Options

Cogent System Panels utilises a range of plastic technology products and

specialised engineered components by Dow Chemical Company to eliminate

fibrous solutions with irritating concerns. Styrofoam* XPS, Ethafoam* and

Immotus* are amongst the insulating infills often entered into a Cogent Solution.

For projects which require economical solutions, Cogent System* Panels will opt

for fibrous insertions within the composites. However, the panel modules will be

seal round the sides to reduce the irritable effects caused by fibrous insulation

blankets during installation.
