Roofing Osb Vs Plywood

Osb was introduced in the 1970s and steadily gained market share from plywood surpassing plywood in production in 2000.

Roofing osb vs plywood.

Compared to cdx oriented strand board osb is made very differently. At the end it will be your consideration to choose between performance and cost. Plywood is better than osb for subfloors. There is nothing wrong with plywood but for me personally we always go with the osb he says.

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. Both plywood and osb will meet the code. Eventually you can decide which one to use between plywood vs osb for roofing.

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. In our area 1 2 in. Osb sheathing costs a few dollars less per sheet than 1 2 in. Today osb has 70 75 market share and plywood has about 25 share.

However the time it will take to install or remove screws on osb and plywood sheets are the same. Plywood is made with an odd number of layers for optimal strength and performance. Plywood has better performance when it comes to overall durability. 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. Lipinskiy says that both plywood and osb are sufficient but that he does prefer osb. Performance over a long period of time. The reason is very very simple.

Osb win against plywood when it comes to shear strength. And osb is available in 4 x 9 ft. Tall wall and the joists below with a single sheet. However osb is a lot cheaper and more affordable to buy.

Because of this manufacturing process osb is at least half the cost of cdx plywood. Both of them are great for roofing. 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.
