Osb2 And Osb3 Shed Roof

Will the thickness make a difference.

Osb2 and osb3 shed roof.

Typical markings on osb panel. Osb is so strong in fact that it is now used for about 70 of all floor wall and roof sheathing in north america and there are two different types of osb osb2 and osb3. For shed construction there are two commonly used grades of osb. With the osb i normally give it a good couple of coats treatment and or acrypol if you can get it i got shed roof ps that have lasted absolute years with this treatment.

Does it has to be osb3 or will osb2 do. The screened surface also provides a little more. Osb3 sheets certifications met. 9mm 11mm or 18mm.

Osb would be fine for a shed roof 18mm ply is going to be expensive. Direction of text should run in direction of span. En 300 pack quantity. I need to cover approx 18m2.

No interior or exterior use. The two grades of board look very similar and can only be distinguished visually by markings which are sprayed on to the board. Interior or exterior use structural. With the felt in top you have a very sturdy roof that wil last for years.

I roofed my stable with 11mm sheets covered with cheap shed kennel felt three years ago. 16 07 kg moisture resistant. So does it matter on the what timber sheets i use to board the roof. Uses include structural roofing flooring panels agricultural buildings portable buildings type.

Osb3 is just as good as regular shuttering ply. 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. Still as good as day 1. To be honest i want to spend as little as i need to.
