Cogent System Panels is essentially an assembled system using a combination of carefully selected building materials to provide a prefabricated roofing component for performance-rated Acoustics and Thermal Solutions.
The panels were developed and introduced into the market after much research, which provided a base of knowledge regarding current and future building requirements. Historically, the solutions were predicated on the need to change conventional multifaceted designs that involved heavy materials. This made roof top handling very difficult and challenging: resulting in long hours working at dangerous heights with exposure to unpredictable weather including high winds and irritable conditions caused by fibrous materials.
The earlier models have evolved substantially as a result of a continuous quest for improvement, based on consistent interaction with both project consultants and working contractors.
Today, roof designs are becoming more innovative and architecturally challenging to form. Cogent System panels provide solutions to various aspects of execution yet ensuring that the roof system build-up will be simple at installation.
Amongst roofing specialists, Cogent System Panels have become increasingly popular as the prefabricated panels represents simplicity which helps to reduce laborious site works and installation time. Cogent System panel designs help to re-think roof construction to address these issues where possible.
For project designers, roof designs continue to be increasingly complex with more performance criteria to fulfil. The building industry is focused on embracing responsible measures that would help realise energy savings, a healthier indoor environment, recycling of valuable resources and provision of greenery in developments.
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.
Components used in the manufacturing and fabrication of Cogent System* panels are carefully selected balancing the following factors:
The external skin, known as the exoskeleton of the Cogent Panels, consist of a high density @ density 1300-1350 kg/m3 fibre silicate cementitious.
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.board that are AUTOCLAVED to satisfy the most demanding exposure to weather conditions.
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.
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.
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.
All models are tested to ISO 140/1.
