Study Notes

Plywood Overview

  • Plywood is a widely used engineered wood product in India for furniture, walls, floors, and other carpentry projects.
  • It's constructed from thin layers of wood veneer glued together, with each layer's grain perpendicular to the adjacent one.
  • This cross-graining significantly improves strength and stability, reducing warping and cracking compared to solid wood.
  • Plywood exhibits versatility, with various grades, sizes, and thicknesses for diverse applications, from structural (sheathing, flooring, roofing) to decorative (furniture, cabinets, paneling).

Plywood Properties and Advantages

  • Durability: Suitable for partition walls requiring load-bearing capacity and impact resistance.
  • Ease of Work: Easily cut, shaped, and installed, allowing for flexibility in construction and design.
  • Dimensional Stability: High-quality plywood resists warping, shrinking, and expansion due to humidity or temperature changes.
  • Fire Resistance: Plywood can be fire resistant under some conditions.
  • Surface Finish: Smooth surface typically allowing for painting, staining, or laminating for aesthetic enhancement.
  • Uniformity: Plywood is manufactured to be uniform in strength and appearance compared to natural wood. This allows for predictable results in different applications.

Plywood Applications

  • Panels and Screens
  • Vinly Products
  • Partitions
  • Furniture
  • Wall Cladding
  • Ceilings and Cladding

Plywood Cost

  • 6mm thick plywood starts at 38 rupees per square foot.
  • 9mm thick plywood starts at 47 rupees per square foot.
  • 12mm thick plywood starts at 56 rupees per square foot.
  • 19mm thick plywood starts at 83 rupees per square foot.
