Installing Architectural Steel Skins
Sheets of steel can be installed as a skin. CZ has traditionally used screws to install steel sheets. Since 2008, CZ has been using 3M VHB [very high bonding] double sided tape.
Reasons to specify tape construction:
– expresses the materiality without visual interruption of screws
– 7 step installation process, must be done correctly for overhead installation
– permanent install, it is very difficult to remove panels without ruining them
– panels are better supported/tend to lay flat, no dimpling/”oil-canning” caused by screws
– tape is viscoelastic, allows steel to expand/contract without weakening the bond
– tape separates the steel from the substrate and reduces vibration/dampens sound transfer
– interior panels can be hung by continuous tape to create an airtight construction
Reasons to specify screw installation:
– expresses the construction method, nothing is hidden
– simple installation [layout screw holes, drill, install]
– requires less skilled crew to install
– less expensive installation
– screws can be adjusted/shimmed if there are any irregularities in the installation
– panels are easily removed if there is a reason to access the framing/wall interiors
