How plywoods are made?

Plywood is a smooth-surfaced board created by bonding 3-4 wood strips simultaneously. Due to its robustness, longevity, and low cost, plywood is commonly used in interior projects. Plywood along with a veneer laminate looks stunning and easy to shape and handle.

When plywood is used in walls or floor joists, it creates a series of vibrating bodies that absorb sound rather than transfer noise. Sound travels so quickly over such long distances, blocking all noise with heavy items is impossible. Placing plywood on the walls and ceilings creates a series of structures that absorb sound, resulting in a more peaceful environment.
