Low Wind Area Alternate Two Row Roof Fixings
Allowed for Region A, Terrain 3 Wind Loadings ONLY
Installation of two rows between two aluminium
angles
will require twice the expansion gap in
the stainless steel straps.
We also
highly recommend you “season” the panels before
installation to removed some of the permanent contraction the panels are prone to.
“Seasoning” the panels involves laying the panels out in the sun for half a day on one
side, then flipping over for the other side.
For dual row array fixed between top and bottom array aluminium channels,
do not exceed
10 panels per row.
If you need to have more than 10 panels we recommend each row have
aluminium railings.
Why?
Panels strapped top and bottom to an aluminium railing will have
smaller side to side thermal movements.
