Insulated Panels
Two layers of steel bonded to an insulation core, laid vertically when through fixed directly to the side rails, will provide full restraint.

Where the insulated panel is only through fixed on one edge, trapping an under tongue on the adjacent panel the restraint should be adopt but modified as follows; These systems have the bottom tube strut replaced with an angle strut and the diagonal wire replaced with a diagonal screwed rod.

Horizontally laid insulated panels should use the restraint systems and the rail capacities can be obtained from the Toolkit design software. Generally the Insulated panels when laid horizontally should be fixed to the verticals between the rails and not by reducing the horizontal rail cross centres to match the panel cover width.


Twin Skin
Is made up of a inner liner profile and outer weather skin with an internal steel spacer system and thermal insulation. The liner tray is attached directly to the Multibeam side rail using self drill self tapping screws and this in connection with the restraint systems shown on page 67 will provide sufficient restraint to support the values shown in the load tables or design software.

Horizontally laid twin skin usually comprises of a vertically spanning liner tray and internal spacer system with the outer sheet laid horizontally and fixed back to the vertical internal spacer. With this arrangement the inner liner is through fixed to the Multibeam rail. When used with the restraint systems, provides the necessary restraint to support the values shown in the load tables or Toolkit design software.


Firewall
Multibeam side rails can be used to support steel cladding based firewalls using either Insulated panels or twin skin cladding.

As long as the Multibeam side wall system is sufficiently designed to support the normal applied loads (dead weights and wind loadings) it will also support the requirements when the same cladded wall operates as a firewall.
