| When used in roof
applications, the construction can be safely undertaken down to a 4
degree pitch using conventional through fasteners.
Factory assembled windows, rooflights and flashing
accessories complete the system, offering cost effective, fully
insulated "warm construction" for industrial and commercial
buildings.
Curved eaves and ridge details can also be
accommodated to complement the Trisomet system. The panel
specification can be matched with a range of fasteners, sealants and
flute fillers.
