Joints in OSB sheathing

[ThomasD]

I am stick building 145mm panels for a 60msq workshop building. 
 

My question is should the vertical joints in the OSB sheathing be: 

 

1. Between the vertical 145mm studs (with 2mm expansion gap between boards)

 

2. Centered upon a vertical stud. (Theoretically, in terms of racking resistance, this option is obviously better but realistically it’s difficult to fasten with a nail gun the edges of the two sheets onto one stud)

 

option 1 is obviously a lot easier!

 

Thanks.

Option 2 is all I have ever seen and no problems with a nail gun.

When I lined my warm loft with OSB I didn’t bother lining up on rafters, instead I joined panels with 100mm strip of OSB, bubble glued and screwed (to make it airtight), saved a lot of waste.

Option 2, 2mm or 3mm packer between

As it is a workshop, go with the @joe90 method.

Many thanks for the replies, I’ll go for Option 2.

Remember to buy your osb so you know what size it is, if it’s imperial it will be 1220mm wide not 1200. 

You should use a full sheet on the corners.
