Whether you are building remodeling or just doing some repairs many times you need a type of sheathing or underlayment for the project.
Osb vs sheathing and siding.
They attach to the exterior wall framing and brace the walls against positive and negative forces.
Tall wall and the joists below with a single sheet.
Pretty much the same for any manufactured wood product and even natural wood that is not naturally rot resistant such as pine.
Osb would not be my first choice.
Two common types of structural wall sheathing are oriented strand board osb and fiberboard sheathing.
Sheets which means you can sheathe an 8 ft.
Both are wood products which makes them earth friendly.
In our area 1 2 in.
And osb is available in 4 x 9 ft.
Osb sheathing has one irritating characteristic but only if you abuse the stuff.
Any portion of osb such as the bottom edge or the backside on any overhangs that is not sealed and or painted is destined to fail and rot.
Since sheathing what plywood or osb are called when used on the exterior of a house is rarely if ever seen again once you cover it up with siding or shingles it s important to choose the right materials for the job.
When considering plywood for sheathing builders choose from 1 2 inch cdx common construction grade material or 1 2 inch pressure treated plywood.
