Grossbond A2

ACP Grossbond A2 Premium is used for facing facades of buildings for various purposes in structures of ventilated facades and window slopes.

Fire safety is one of the main properties of ventilated facades. Cladding and insulating layer during combustion can release substances that greatly affect the intensity of the fire. To reduce the spread of fire is supposed to install fire cutoffs of non-combustible materials.

Fireresistant aluminum composite panels Grossbond A2, due to the high content of additional mineral components – flame retardants – achieve high fire resistance.

Sphere of application

Grossbond A2 fireproof aluminum composite panels are recommended for application in ventilated facades to install window jambs as part of fire barriers. The perimeter of window and door openings, walls and corner areas and the presence of fire escapes are needed to be taken into account to accurately obtain the required number and space of fire barriers.

Fireproof frames should be designed down to the smallest performance detail in a ventilated facade system. A fire barrier should not completely block the airflow, so it should be perforated. However the important nuance that is frequently overlooked is that even with perforations being provided a fire barrier greatly affects the airflow in the gap. So to avoid excessive moistening, allowance should always be made for a fire barrier in the design of the structure.

The heat of combustion of the inner layer of fire-resistant ACP Grossbond A2 is almost 2-3 times less than the requirements for low-combustible facade materials, and its properties are close to foreign non-combustible analogues.

Advantages

• low flammability
• core caloric value of 5.65 MJ/kg
• ease of installation
• reduced cost of the facade
