These two materials receive lots of question from our customer. This following features will give you the answer.
The same characteristics
– OSB and plywood can both be used for walls, floors and roofs and applied by using contructural technical. But there are some differences between them.
About constituents, OSB are rectangular shaped wood strands layered in specific orientation and combined together with wax and resin adhesive. Meanwhile, plywood is made of thin sheets of veneer glued together.
The outer layers of OSB are aligned parallel to the strength axis of the panel and inner layers are aligned perpendicular to the axis.
– Plywood consists odd number of layers with grains of adjacent layers at right angles to each other. Face veneers are higher grade than the core veneers.
OSB is widely applied in constructing roofs, walls, subfloors. Plywood proves its advantages with more uses in roofs, walls, subfloors, boxes, packages, sports equipment, musical instrument, playground equipment, high-end loud speakers.
Strength and durability
Both plywood and oriented strand board (OSB) are equal in strength and durability. They are all recognize in their prooerties and use the phrase “wood structural panel” to describe. However, OSB floors are more likely to:
– Squeak due to movement
– Cause hard floor surfaces to crack
– Result in soft, spongy floors
It should be noted that some OSB manufactures use advanced technology to make higher quality OSB panels, including the more moisture-resistant products. There are more expensive than traditional OSB but may well be worth the price given their durability and
