Here’s how Building can prevent fire?
High-rise buildings highlight the prosperity of a city, but the hidden danger behind the prosperity, let a person engraved on his mind.Fire, a disaster no one is unfamiliar with.
Table 2.1 gives a summary of the recent major facade fire incidents that took place around the world. In all cases, it was evident that there has been a rapid fire spread along the exterior cladding due to the combustibility of the materials used. Although sprinklers were installed, external fire spread was not prevented that considerably reduced the evacuation time for occupants. The cases of apartment buildings where the occupancy is relatively high throughout the day turned out to be catastrophic events, which ultimately resulted to loss of human lives.

The once Harrowing Apartment Fires in London and Australia,The government began to pay attention to the materials used for building exterior walls and issued a series of regulations to ensure safety.
A 24-story building with 120 apartments was gutted by flames, in what authorities called London’s worst building fire in years. The fire has claimed at least 30 lives.
These fire is related to the flammability of the materials used in the building's exterior walls.
Aluminium-plastic composite panels are used as cladding in both UK and Australian Melbourne buildings. The Melbourne fire is similar to the London fire in its speed of spread, which has been described as "unprecedented" . In fact, the aluminum-plastic composite board with polyethylene plastic as the core and aluminum alloy as the outer layer has become a widely used building material in the world because of its beauty and cheap price, but it is full of fire hazard.
In Australia, France, the United Arab Emirates, South Korea and the United States, there have been cases of fire caused by the use of aluminum-plastic composite panels in building materials.
Australia is in the midst of a construction boom, and our top priority is to have a fire certification law and standards that meet current and future needs.
In general, all energy conservation and emission reduction should be based on the residents to bring a better and greener future for the point of departure, the installation of flammable building materials in the residents' external walls, is tantamount to laying fire, good can not be talked about. Even if the country wants to save energy, the builders want to make money, and residents want to rest assured that there is a partial contradiction between the three, the matter should be better resolved.
The Australian Bureau of Standards recently completed the development of AS5113, fire propagation testing and low wall classification of buildings.
Through proper classification of external wall performance, improve fire safety Improving energy efficiency
Improvement of selection criteria for exterior wall materials / systems in the construction industry
Savings in reducing compliance costs and promoting the use of cost-effective external wall systems.
Combustibility of materials are classified in accordance with EN 13501-1 (European Committee for Standarization 2009) as A1, A2, B, C, D, E and F with A1 being the highest performance and F being the lowest.
Aluminium Composite Panels (ACP)
Aluminium composite panels (ACP) are flat panels made from aluminium composite material (ACM), which consists of two or more laminates bonded together. The primary components of ACPs is comprised of two outer aluminium sheets, coated with non-combustible PVDF paint or similar coatings, and then bonded together to a combustible polyethylene (PE) or fully non-combustible core. Aluminium is renowned as a flexible and durable material which can withstand extreme weathers and resist the effects of harmful UV light(Stacey and Bayliss 2015). Hence, ACP can last for a long period of time. Available ACP products in the market come in different colors and sizes but are typically 3 to 6mm thick. The usual application of ACP are widely used for facades of buildings, design for exterior or interior walls, columns, noise and thermal insulation, and signage. Some of the advantages of ACP include easy installation, low maintenance due to its water resistant properties, architecturally attractive, lightweight, and boasts excellent facade skin properties.
Current issues of ACP panels lies on the question of their combustibility. Recent catastrophic events have led to the understanding of how rapidly and easily fire propagates from floor to floor, with the fire originating from the facade system or internal fire spreading to the facade system. This can be due to various factors, such as the combustible material or improper installation. Although this can be regarded as a low frequent event, the impacts on life and properties can be significantly high. The type of core material used in ACP can generally influence to the material’s resistance to fire. For a product to be considered compliant, Deemed-to-Satisfy conditions must be satisfied as given in the Australian NCC. One of the alternative solutions is for the ACP to be evaluated and verified by a third party certification body. Cert Mark International (CMI) accredits and certifies ACP products to show compliance against specific standards. CMI categorized the different types of ACP according to its type, fire rating, use, and restrictions. There are different types of core depending on its fire resistance, namely: 1) Polyethylene 2) Fire Resistant (FR) 3) A2, and 4) A1 Aluminium-core ACP. ACP with PE core are restricted to Type C construction as it is considered flammable or combustible. Also, it should only be used for signage, low rise development, factories and warehouses. FR panels on the other hand, consists of a mixture of PE and minerals, which gives low fire indices that do not contribute to the propagation of fire and development of smoke. One condition for use of fire rated panels is that it should be attached to a fire rated wall. Hence, fire rated panels are applicable for use on high rise structures. A2 panels, which derived its designation name from a fire test, consists of minerals to stop fire and smoke propagation. Both A1 and A2 type panels are classified as non- combustible panels, which are both acceptable for use on high rise structures (according to ABD), and also have the same condition that panels must be attached to a fire rated wall (CertMark International 2017).

With the development of modern architectural design and standards, the traditional curtain wall materials slowly exposed various defects.After years of research and experiments,our curtain wall materials and equipment development team finally invented a new generation of A2-level fire patented product --aluminum-core composite panel(ACCP)
In addition to the physical advantages of the structure, Aluminum core composite panel used in the curtain wall and other decoration also has unparalleled ultra-flatness.
The aluminum core composite panel with a special structure, any process on the back will not affect the flatness of the aluminum panel surface.However,Aluminum solid panel bending process due to the four corners of the plate have inevitable bending tension, resulting in uneven surface. The middle layer of the aluminum composite panel is a plastic core layer,when the temperature changes,the thermal expansion and contraction coefficients of the core layer and the aluminum layer are different,resulting in poor flatness of the aluminum composite panel surface.For the above two defects, the solution is generally used to install stiffeners, aluminum solid panel stiffeners cost is very high, aluminum composite panel stiffeners process is cheaper, but once use the stiffener, there may be no adverse phenomena in a short-term , after a period of time or summer and winter temperature difference conversion, the stiffener rib will be embossed in the aluminum panel surface,affecting the appearance.
Reducing construction and labor cost
Aluminum core composite panels with ultra-light and super strong structure, in the design of larger size plates, regardless of the curtain wall or ceiling in the back of the framework of the gap can be expanded, in addition to the panel itself the price advantage, but also can save the cost of keel and labor costs up to more than one-third, as well save construction time.
Aluminum core composite panel due to a special three-dimensional structure, lining ribs should be used only T-BAR, economic and convenient.
Diversified selections of fine surface finish
The aluminum layer of Aluminum core composite panel use the roller coating or continuous anodizing process, the surface delicate exquisite,the appearance of a variety of options, whether imitation stone, imitation wood or brushed, mirror, can be perfect Show.
Is the wall entirely non-combustible?Would it perform long-term(without the cladding)as the building's BCA
compliant external wall?
ACCP-this means the cladding is considered an "attachment" and your aluminum clading with a "FR","PLUS",or "A2" grade core is more than likely considered compliant!
By using non-combustible aluminum cladding(such as ACCP),you can eliminate this secondary non-combustible layer and save your company around $50-100/㎡.
