AAC/ALC Panel Characteristics and Advantage

Author:manager   Time:2017-05-10 15:57:47 Hits:525 Tags:

In comparison with the autoclaved aerated concrete block, AAC or ALC panel has the characteristics as following:

A. Panel Features
a. Heat Preservation and Insulation
With the panel, no heat preservation measures are needed. Therefore, the construction cost will be significantly decreased. In addition, the building requires less energy consumption.
b. Fireproof Performance
The 15cm thick AAC panel can resist fire for at least 4 hours, and no radioactive substance or harmful gas will be produced. This panel is extensively used to the application where excellent fire resistance is required, for instance, the factories of steel structure.
c. Perfect Resistance to Shock
The lightweight ACC panel of high intensity applies the special joint design and installation method, to make sure the excellent shock resistance of the buildings. For this reason, it is commonly found in the seismic zone.
d. Convenient Construction
The dry construction method is used for the AAC panel. It needs short construction period. With this method, you can save about 80 Yuan for per square meter.
e. Larger Indoor Area
Unlike the wall made of autoclaved aerated concrete blocks, the AAC panel wall is at least 50mm less in thickness.
