Mi Panel is the cost-effective solution to reducing dependency on wet works within the built environment of the construction industry and this applies to all types of construction, including low cost, affordable and high-end residential construction, commercial and industrial construction as well as to public sector institutions.
Mi Panel is one of the solutions to the challenges faced within the built environment to build ‘Green’ in a sustainable manner that is environmentally responsible and which significantly reduces or eliminates its negative impact on the environment.
The system of construction with Mi Panel is easily taught to unskilled labourers and MIBT will provide extensive training and warranty back-up options on construction. Mi Panel mostly exceeds structural tests for lightweight construction and is suitable for the application of a wide variety of surface finishes, including paints and aggregates, as well as cladding, design beading and all most all other finishes that can be accommodated on conventional construction. The fibre cement facings are completely resistant to rising damp as well permanent water damage making Mi Panel suitable for use in wet area applications.
Airborne Sound Transmission Loss
STC (Sound Transmission Class) – STC figure is found by plotting the Sound Transmission Loss figures in 16-1/3 octave bands from 125 Hz to 4 KHz on graph and fitting the STC contour over as detailed in ASTM E413-73. The rating is read at the 500 Hz intersection with the STC contour.
Average Sound Reduction Index (R) Calculation
R is the mathematical mean to the nearest decibel of the values calculate in 16-1/3 octave bands from 100 Hz to 3.15 KHz. Sound insulation of panel walls may be easily increased by adding additional materials to wall surfaces internally or externally, doubling of panels or provision of a cavity in the wall composition.
Comparable Strength of the Mi Panel to other materials commonly used in simple building construction.
In order to compare the strength of the Mi Panel used in wall structures to that of other materials commonly used in simple single storey buildings, structural engineers, Wood & Grieve, who have been involved with Mi Panel since its inception, have examined these materials in a typical location under wind load. The bending stresses acting on the various wall types using the different materials have been calculated and these values
divided into the ultimate loads in order to obtain a “relative strength factor” in order to allow comparison between Mi Panel and other wall types. The results set out hereunder and intended only as a guide to the
strength of the Mi Panel as each particular wall structure requires independent analysis.
Thermal Properties of Mi Panel.
Terms used in calculating heat transfer.
- Thermal Conductivity (K) – W/WK or W/MoC – This is a property of the material regardless of thickness – a measure for the material’s ability to transmit heat. The units measure heat flow in 1 m2 of material for a temperature of 1oC per metre thickness.
- Thermal Resistivity (1/K – MK/W or MoC/W – Usually defined as the reciprocal of thermal conductivity.
- Thermal Resistance (R) – M2K/W or M20C/W – Every material has a thermal resistance which determines
the amount of heat transmitted through it. The higher the R value the better heat insulation the material provides. If the thickness of the material is known, the thermal resistance can be calculated by multiplying resistivity by thickness in metres.
- Thermal Transmittance Coefficient (U) – W/M20C or W/M2K – This is the reciprocal of the sum of the thermal resistance of the various materials that make up the composition of the panel or wall structure.
Mi Panel was tested by the CSIRO Division of Building. Construction and Engineering in accordance with Australian Standard 1530, Methods of Fire Tests on Building Materials, Components and Structures, Part 4–1990; Fire Tests on Building Materials and Structures, Parts 20 & 22, 1987 on 25 July 1991. Certificates of these tests have been provided.
