Plywood is a widely used construction material due to its strength, versatility, and durability. The most common plywood materials used in construction today are:

Softwood Plywood: This type of plywood is made from softwood trees such as pine, spruce, or fir. It is commonly used in construction for roof sheathing, subfloors, and wall sheathing.

Hardwood Plywood: Hardwood plywood is made from hardwood trees such as oak, birch, or maple. It is often used for decorative purposes such as cabinetry, furniture, and paneling.

Marine Plywood: Marine plywood is specially designed to be used in water and humid environments. It is often used in boat building, docks, and other marine applications.

Exterior Plywood: Exterior plywood is designed for outdoor use and is often used for exterior walls, roofing, and subfloors. It is made from waterproof glue and is resistant to moisture and weather.

Structural Plywood: Structural plywood is designed for use in construction projects that require a high degree of strength and durability. It is often used in building frames, roofs, and floors.

Fire-Retardant Plywood: Fire-retardant plywood is treated with chemicals to slow down or prevent the spread of fire. It is often used in buildings that require additional fire protection, such as schools, hospitals, and high-rise buildings.
