Osb Vs Plywood 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.

Osb vs plywood for roofing. 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. Plywood is better than osb for subfloors. Because of this manufacturing process osb is at least half the cost of cdx plywood. Compared to cdx oriented strand board osb is made very differently.

When the roofing material cannot hold nails and screws properly of course they cannot hold its shape very well. Screwe holding ability is a critical matter in roofing. Lipinskiy says that both plywood and osb are sufficient but that he does prefer osb. 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.

There is nothing wrong with plywood but for me personally we always go with the osb he says. You can consider this as an advantage but it can also have some drawbacks. You won t have to worry about the material expanding anytime soon like when you use osb. Osb vs plywood screw holding.

Although we did mention that there is an osb today which is manufactured to be resistant to wet conditions. This is why plywood is considered as the better option for roofing. Both plywood and osb will meet the code. Osb is made by combining glue resin and wood chips and pressing them into the shape of a plywood sheet then baking everything together.

Plywood is the ideal material for places having a wet weather condition. New homes will usually see a few rainfalls before a roof is on and as noted above osb doesn t handle moisture well. Osb boasts a more consistent density. The reason is very very simple.
