I’ve never been a fan of particle board. They tried renaming it OSB and now it looks like a new rebranding to Laminated Strand Lumber. But the can’t fool me. It’s still particle board.
Particle Board is not the same as either OSB or Laminated Strand Lumber.
Particle board was made with sawdust and an Interior glue.
It was made to be the core of furniture, like a table top.
OSB and Laminated Strand Lumber is formed into multiple layers with larger wood chips and a WATERPROOF EXTERIOR GLUE. Which is why mills like Huber can offer a 50 years warranty on their Advantac underlayerment.
The adhesives holding together the wood is very expensive.
There are many wood products like finger joint lumber that use a glue similar to Gorilla Glue. It is very expensive and
will never come apart. The bond is stronger than the wood itself.
All of these products are made to be more dimensionaly stable than solid wood. The LMS Studs are used in a lot of high end houses especially in the walls in the kitchen where they are going to mount kitchen cabinets. That way the walls are perfectly straight and plumb. It makes the cabinet installation much easier.
