Structurally
glazed mullions with flat transom covers.
The
snap covers are retained by friction, the mullions and transoms
will resist a
pull-off load of 2.0kN/m with a safety factor of 2.
For
mullions at 1200mm centres, this equates to a wind load not
more than 1700Pa. Higher wind loads may require screw on flat
snap-on covers or an alternative system.
