What is Plywood?

Answer:
Considered to be one of the top underlying building

materials for home construction, plywood is a widely recognized wood product. Plywood is made by processing thin layers of wood, sandwiched together and bonded into heavy duty sheets using high pressures and layers of wood glue. Plywood comes in various grades, from A to D and refer to the level of surface flaws. ‘A’ has the best surface, with the lowest number of flaws, with ‘D’ having the highest number of allowable surface flaws.

Another feature of plywood that goes hand in hand with the grading system is the bonding type.

The bonding or glue used in the plywood processing determines where the plywood can be used. Exterior plywood uses a glue that withstands exposure to moisture, allowing it to be used for all sorts of outdoor projects. Interior plywood, also known as furniture grade plywood, does not withstand moisture as well and is typically used for furniture applications. Structural plywood tends to have the lowest grading and is used underneath other materials to offer structural strength, while marine plywood focuses primarily on bonding with the highest moisture resistance. Marine plywood is typically found with the highest grading and is limited to woods that have the best moisture resistance.
