Fixing Curtain Walling to the Structure ~ in curtain walling systems
it is the main vertical component or mullion which carries the loads
and transfers them to the structural frame at every or alternate
floor levels depending on the spanning ability of the mullion. At
each fixing point the load must be transferred and an allowance
made for thermal expansion and differential movement between the
structural frame and curtain walling. The usual method employed is
slotted bolt fixings.
