Ensure roof trusses are in proper alignment with no curves or uneven sections when installing osb to sheathe roofs.
Roof with osb.
Oriented strand board commonly referred to as osb is a type of engineered lumber similar to particle board formed by adding adhesives and then compressing layers of wood strands.
Avoid the errors described when installing this roof sheathing.
Osb is made out of strands of wood chips and chemically engineered materials to glue them together.
Install osb panels on aligned roof trusses.
When they are used in roofing osb can retain heat and water perfectly.
This case is most certainly the exception to the general rule and happens in far less than 5 of all post frame buildings.
Oriented strand board or osb roof sheathing is a preferred material for roofing because of its strength and low weight.
However the board is lack of natural moisture inside and won t dry as quickly as plywood.
The only reason to put osb on a roof would be in the case of a very narrow very long very tall building with high wind loads ones which would exceed the wind shear carrying capacity of the steel.
In order to obtain the thin sheets of laminate to make plywood manufacturers have to slice them from.
As the result they are stronger and basically water proof.
Osb is widely used as roof decking material.
