OSB

Oriented strand board (OSB) is a type of engineered wood formed by adding P-MDI adhesives and then hot compressing layers of wood strands/flakes

PROPERTIES:

OSB is typically used in construction. The most common uses are as sheathing in walls, flooring, and roof decking. For exterior wall applications, OSB is also used in furniture production.

Load-bearing capacity
OSB does not have a continuous grain like a natural wood
Ridged/strong
OBS is similar in weight to ply wood. Typical densities are 600 kg/m3 to 680 kg/m3

Applications:

MDF is regarded as a good substitute for wood and other materials as it is relatively cheap, comes in large and regular sheets.

Cut OBS with a circular saw. For straight cuts, it is easier to feed the sheet of OSB through a table saw. For curves, use a router, jigsaw, or coping saw.

OSB cannot be sanded to take on a particular shape, but a light pass with sandpaper will smooth out the surface so splinters don't scratch the bottom of the material you install over the OSB.

Sustainability:

Benefits to OBS is it has a Low footprint, OSB can be produced from small trees that are usually farmed. In addition it is usually made with resins that contain less formaldehyde than plywood, MDF and particle board.

However OBS uses a high amount of energy in its production it needs high heat and pressure to be produced, just like plywood, particleboard and MDF.

OBS cannot be recycled,waste can only be incinerated and because of its low durability it cannot be easily reused.

Material Handling:

Use in a well ventilated area to avoid inhalation of resin fumes.
Wear a dust mask while sanding to avoid dust inhalation which can cause short and long term damage to the lungs.

Protective Equipment:

Dust mask
Tightly fitting googles.
Gloves
