Osb Flooring Which Side Up

A plywood subfloor generally uses 1 2 inch to 3 4 inch thick sheets of plywood that have one rough side which faces down and one smooth side which faces up.

Osb flooring which side up. If you lay the sheet the other way it doesn t provide proper moisture protection and moisture protection is everything when it comes to laminate flooring. The smooth finished side goes up when you install osb as a subfloor. The other side is rough really rough with a cross patch and i assume that is the exposed exterior side but question it because i know how hard it is to. For weyerhaeuser edge gold the down pores must be faced down in order for the self draining system to work correctly.

Meaning that when the osb edge gold is placed on the floor the pores should not be seen. The sheets are generally 4 x 8 or 4 x 12 feet in size. However structurally there is no difference in how the panel will perform whether the side with the grade stamps is installed up or down. 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.

I want to use osb sheathing to side a shed on one side there is print that tells all the specs of the osb and seems smooth and says this side down but i find that this side is smooth and it is going to be painted with exterior paint. When the grade stamp is covered by roofing the building inspector will not be able to confirm that the correct osb roofing panel was used. An osb sheet has a finely corrugated unfinished side and a smooth side that is often coated with a clear finish.
