75 mm E-METRIX® Panel Wall
External Wall System for Low-rise building applications
The E-METRIX® brand of reinforced autoclaved aerated concrete (AAC) panels are suitable for many different building applications including external or internal walls for low-rise and high-rise construction. The superior performance of the reinforced AAC panels with regards to fire resistance, thermal efficiency and sound reduction make it an appealing choice for builders, developers and the like. This is especially so when the increase in speed of construction that the panel provides is taken into account.
System Overview
The 75-mm E-METRIX® external wall system for low-rise buildings consists of a single 75-mm E-METRIX® fixed to a structural frame using steel tophat battens forming a cavity external wall system. The external side of the structural frame has a pliable membrane attached to it while the internal side has plasterboard attached. The system provides the necessary weatherproofing, thermal, fire resistance and sound attenuation required by the NCC
Structural
The 75mm E-METRIX® component of the low-rise external wall system is a non-loadbearing component, it does not support vertical load other than its self-weight. It is the stud framing that is the load-bearing component.
However, the 75-mm E-METRIX® and its attachment back to the stud framing are required to resist lateral (out-of-plane) loading which typically caused by wind.
Weatherproofing
The weatherproofing of the external wall system has been successfully tested in a NATA accredited laboratory in accordance with AS/NZS 4284 for a serviceability pressure of ±1.00 kPa. Thus, it is suitable for wind classifications N1, N2, N3 & C1 as per AS 4055
Fire Resistance
The 75mm E-METRIX® reinforced AAC panel is the main fire resisting element in the low-rise external wall system detailed in this technical manual. However, the internal plasterboard lining and fire rated sealed joints are integral to the overall fire performance. The 75mm E-METRIX® has been tested by CSIRO in accordance with AS 1530.4 and the low-rise external wall system assessed to provide an FRL performance of 90/90/90 which exceeds the NCC requirements.
Acoustic
Where a class 1 building is constructed close to a road or rail corridor, the acoustic performance of the external wall should be an important consideration.
The 75mm E-METRIX® has been tested by CSIRO in accordance with AS/NZS 1276.1 and the low-rise external wall system assessed by a leading Australian acoustic firm.
Thermal
The 75-mm E-METRIX® provides significant thermal performance resulting in comfortable living spaces for low-rise residential buildings. The thermal resistance of the wall system using various types of insulation is outlined below.
“The best part is that Emtrix comes with a 2 year warranty and great after sales support.
