Box profile cladding installation

[mgarym]

Hi,
I'm installing 32/1000 box profile cladding on a portal frame shed,when it comes to translucent sheets on sides and roof im not sure whether the plastic sheet should be over or under the metal cladding.
I have been told plastic under metal but when it is under the metal
the stitching screws won't pull the metal sheet down to make a good joint.
What is the correct method?

Thanks Gary

You can either lose a lap of the translucent sheeting or rip down a rib section of the steel cladding and slip it under/over like a big washer sandwiching the baggy eng of the sheet. I have had to do the same.

I would lay it the same way as the cladding sheets, with the butyl sealing strip down the joints as well as the screws it sticks it all together fine

Thanks all ,went for the same layout as the normal sheeting, with the tin in below the stitching screws were able to pull the plastic down to get a good seal.
