I need to reboard my shed roof before i fiberglass it or felt it haven t decided yet.
Osb2 and osb3 shed roof.
Osb roof panels should always be installed with the grade stamp facing into the attic and the screened surface with the nail guide lines facing up.
Typical markings on osb panel.
9mm 11mm or 18mm.
Interior or exterior use structural.
The two grades of board look very similar and can only be distinguished visually by markings which are sprayed on to the board.
Osb2 is great for structural non load bearing projects in dry conditions whereas osb3 performs better for structural load bearing use and for use in humid conditions.
Will the thickness make a difference.
Does it has to be osb3 or will osb2 do.
Osb3 sheets certifications met.
For shed construction there are two commonly used grades of osb.
Direction of text should run in direction of span.
To be honest i want to spend as little as i need to.

I roofed my stable with 11mm sheets covered with cheap shed kennel felt three years ago.
Uses include structural roofing flooring panels agricultural buildings portable buildings type.
No interior or exterior use.
With the felt in top you have a very sturdy roof that wil last for years.

Osb3 is just as good as regular shuttering ply.
Osb would be fine for a shed roof 18mm ply is going to be expensive.
The screened surface also provides a little more.

So does it matter on the what timber sheets i use to board the roof.
