Shear Load Transference - Shear load is transferred by rivets 
into the floor / ground surface or the perpendicular walls, ceiling 
& roof at a rate of 1.21 kN per 4.0 mm diameter rivet.
Fixing rivets at 200mm centres complies with the 20-minute 
flame barrier requirements and delivers 14.5 kN of shear 
capacity transfer per panel (6 on each side) horizontally, and 
12.1 kN per metre in vertical joints. Limited by the ability of the 
panel to transfer the shear.
*   Figures for 1.2m & 4.8m high panels are extrapolated.
  It is acceptable to extrapolate Bracing Capacity heights  
  between 1.2m & 4.8m. For heights outside of this dimension  
  range, Diaphragm Analysis is required to establish Bracing  
    Capacity.

 Handling & Installation
DeltaCool-MW core material is fibrous as such it is easy 
to fracture the mineral wool fibres if handled and installed 
incorrectly. Please ensure that correct lifting equipment is used 
when the panels are transported and lifted into position. Refer to 
the Handling & Installation Manual - Wall Systems for the correct 
Crane & Sling Procedures.

Acoustic Values
Acoustic Testing has been performed in compliance with 
the requirements of AS 1191-2002 “Acoustics - Method for 
Laboratory Measurement of Airborne Sound Insulation of 
Building Elements”.
The procedures specified by AS/NZS ISO 717.1:2024 were 
used to calculate the Sound Transmission Class (STC) and the 
Weighted Sound Reduction Index Rw = 25 dB.
