Extra battens for added insulation

[Maccca99]

I have a 12ft x 10ft shed 2-2.5m high, with 37mm x 67mm posts, on walls and roof.

This means I can only put in 50mm insulation, allowing for breathable and vapour membranes. I'm not sure that would be warm enough for a large space.

If I were to I fix 37mm x 50mm battens to all the existing posts I could then put in 100mm insulation.

Would the structure be stable if I did that? I plan to use 18mm OSB to board.

Any advice appreciated.

Do you plan to heat or cool the shed?

Heat it, use it as a kind of summer house but also through the winter
