Hi,

I started virtually building a small shed in SketchUp. Due to the dimensions of the materials used, there would be a gap in the very top.

My question is whether I can leave the gap as it is as the sheathing would be covered with Proclima Solitex, then wood fibre insulation panel, then corrugated steel. I was thinking the gap would facilitate moisture getting out from inside.

I live in Melbourne, Australia. The temperature zone is mild temperate.

Thank you.

Regards,
Xiao
