Roofing osb vs plywood.

Both plywood and osb will meet the code. Osb sheathing costs a few dollars less per sheet than 1 2 in. At the end it will be your consideration to choose between performance and cost. Performance over a long period of time.

As a homeowner if you find yourself in this position know that when you install a new decking system you will have to decide between using plywood or osb. Osb was introduced in the 1970s and steadily gained market share from plywood surpassing plywood in production in 2000. Today osb has 70 75 market share and plywood has about 25 share. Because of this manufacturing process osb is at least half the cost of cdx plywood.

Both of them are great for roofing. Eventually you can decide which one to use between plywood vs osb for roofing. One of the nice things about plywood is the variety of options you can buy. Despite its common use as such we don t recommend using osb for subfloors but that s really just for aesthetic reasons.

The reason is very very simple. New homes will usually see a few rainfalls before a roof is on and as noted above osb doesn t handle moisture well. Osb is made by combining glue resin and wood chips and pressing them into the shape of a plywood sheet then baking everything together. Osb sheathing has one irritating characteristic but only if you abuse the stuff.

There is nothing wrong with plywood but for me personally we always go with the osb he says. Lipinskiy says that both plywood and osb are sufficient but that he does prefer osb. Osb win against plywood when it comes to shear strength. Plywood is made with an odd number of layers for optimal strength and performance.

In our area 1 2 in. Plywood has better performance when it comes to overall durability. Compared to cdx oriented strand board osb is made very differently. As osb is cheaper than plywood and has the strength and durability of plywood it is becoming more widely used than plywood.

And osb is available in 4 x 9 ft. However the time it will take to install or remove screws on osb and plywood sheets are the same. Up until 2000 plywood held the majority of the market for wall roof and floor sheathing when it was surpassed by osb which as of 2018 held about 75 of the market share.
