Osb Vs Plywood Roof

Both osb and plywood absolutely hate water lipinskiy mentions going on to say that the most important part regardless of which decking option you choose is that all penetration points on a roof are sealed.

Osb vs plywood roof.

While a sheet of plywood might be 5 to 7 plies thick a sheet of osb is made from as many as 50 strand layers packed and compressed into the same thickness. A few other downsides to plywood. Water test the edges of the 1 2 in. However osb is a lot cheaper and more affordable to buy.

Plywood has better performance when it comes to overall durability. Oriented strand board osb board that soaked in my bathtub overnight swelled almost 1 4 in. Both of them are great for roofing. Alternatively osb is created from wood chips resin and adhesive that is baked and formed into the shape of a sheet of plywood.

Thankfully there are osb materials today that are designed to be moisture resistant. Osb was introduced in the 1970s and steadily gained market share from plywood surpassing plywood in production in 2000. Osb is made by combining glue resin and wood chips and pressing them into the shape of a plywood sheet then baking everything together. New homes will usually see a few rainfalls before a roof is on and as noted above osb doesn t handle moisture well.

At the end it will be your consideration to choose between performance and cost. Plywood is created by taking extremely thin sheets of wood called plies and gluing them together. It is extremely resistant to moisture. The thickness of the plywood can be controlled by the number of plies glued together.

Eventually you can decide which one to use between plywood vs osb for roofing. As osb is cheaper than plywood and has the strength and durability of plywood it is becoming more widely used than plywood. Despite its common use as such we don t recommend using osb for subfloors but that s really just for aesthetic reasons. Osb panels can be manufactured in lengths up to 16 feet or sometimes even higher while plywood is generally limited to 8 to 10 feet.

Osb boasts a more consistent density. And stayed swollen while the plywood remained stable. Plywood is better than osb for subfloors. How it s made plywood vs.

It becomes soft and weak when it delaminates. Despite also being susceptible to water damage lipinskiy says that. This is one of the reasons why some people prefer using plywood for their roof or subfloor. Osb these sheets of wood may look similar but they are not created the same.

Because of this manufacturing process osb is at least half the cost of cdx plywood. Unfortunately an osb is less resistant to water compared to plywood. Compared to cdx oriented strand board osb is made very differently. The curb appeal of your home is lost because soon your shingles will start to misalign creating an eyesore on the top of your home.
