Plywood decides how long your furniture, wardrobes and kitchen last, especially where water is involved. This guide covers the grades sold in India, how plywood compares with MDF and particle board, the IS codes that certify quality, and how to pick the right thickness.
Quick answer: which plywood grade
| Grade | Water resistance | Best for |
|---|---|---|
| MR | Moisture resistant | Dry interior furniture, wardrobes in dry rooms |
| BWR | Boiling water resistant | Kitchens, semi-exterior, damp areas |
| BWP / Marine (IS 710) | Fully waterproof | Bathrooms, outdoor use, heavy moisture |
The single most common mistake is using MR grade in a kitchen. In any wet area, step up to BWR or BWP.
Grades explained
The grade is about the glue and its water resistance, not the wood. MR (moisture resistant) uses urea-formaldehyde glue and suits dry indoor furniture. BWR (boiling water resistant) uses phenolic glue that survives kitchens and occasional wetting. BWP or marine grade, certified to IS 710, is fully waterproof and made for bathrooms, outdoors and constant moisture. Interior commercial plywood is covered by IS 303. Our plywood grades MR, BWR and BWP guide explains how to verify the grade you are paying for.
Plywood vs MDF vs particle board
These three are not interchangeable:
- Plywood is layered wood veneers, the strongest, best at holding screws and tolerating moisture. Use it for load-bearing and wet-area furniture.
- MDF is dense fibreboard with a smooth surface, ideal for painted panels, doors and mouldings, but weak with screws and poor with water.
- Particle board is compressed wood chips, the cheapest, for light, dry, budget furniture only.
Our plywood vs MDF vs particle board comparison breaks down strength, finish, moisture behaviour and cost.
Choosing thickness
| Thickness | Typical use |
|---|---|
| 6 mm | Back panels, light partitions |
| 12 mm | Shelves, general furniture |
| 16 mm | Wardrobes, doors |
| 18 to 19 mm | Kitchen platforms, heavy load-bearing tops |
Thicker boards resist sagging, so match thickness to span and load rather than defaulting to the cheapest sheet.
Buying checklist
- Match the grade to the location: BWR or BWP for anything near water.
- Look for the IS 710 mark on marine and IS 303 on interior grades.
- Check that the sheet is flat, with no warping or core gaps at the edges.
- Choose thickness by load and span, not just price.
- Tap the board: a solid, even sound suggests a well-bonded core.
