The overlaps of this panel are fastened with stitching screws. The secondary framing is normally Z purlins fixed with 1.5m purlin spacing to the primary framing. The thermal insulation varies depending on the type of the built-up roof.
Simple and economical parapets
Can be used for complex roof shapes
Economical rain water drainage
High degree of thermal insulation (depending on the specification of the built-up roof sheets)
