Osb Vs Plywood For Roofing

Osb boasts a more consistent density.

Osb vs plywood for roofing.

The reason is very very simple. Plywood is better than osb for subfloors. You can consider this as an advantage but it can also have some drawbacks. Performance over a long period of time.

Lipinskiy says that both plywood and osb are sufficient but that he does prefer osb. Although we did mention that there is an osb today which is manufactured to be resistant to wet conditions. Osb vs plywood screw holding. 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.

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. You won t have to worry about the material expanding anytime soon like when you use osb. This is why you need to know the screw holding ability between plywood vs osb for roofing.

This is why plywood is considered as the better option for roofing. There is nothing wrong with plywood but for me personally we always go with the osb he says. 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. Despite its common use as such we don t recommend using osb for subfloors but that s really just for aesthetic reasons.

Both plywood and osb will meet the code. Screwe holding ability is a critical matter in roofing. Because of this manufacturing process osb is at least half the cost of cdx plywood. 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.
