Factors Affecting the Price
The 18mm waterproof plywood price list is not uniform across the country. The final price you pay for a sheet of plywood is influenced by a variety of critical factors.
- Brand and Market Position: Established brands like CenturyPly and Greenply invest heavily in research, quality control, and advertising, which leads to a premium price for their products.
- Grade of Plywood (BWR vs. BWP): This is the most significant factor. BWP or Marine Grade plywood is always more expensive than BWR Grade because it uses superior, undiluted resins and a more rigorous manufacturing process to make it fully waterproof.
- Type of Timber Used: The species of wood used for the core veneers inside the plywood greatly affects its price and quality. Plywood made from 100% hardwood veneers like Gurjan will be more expensive than plywood with alternating cores of Poplar and Eucalyptus.
- Certifications and Special Features: Plywood with additional features like fire-retardant properties (FR Grade), low chemical emissions (E0/E1), or other proprietary technologies will be priced at a premium.
- Location and Taxes: The final retail price includes local taxes (GST) and transportation costs. A dealer in a major city may have different pricing from one in a smaller town due to varying overheads.
Tips Before Buying 18mm Waterproof Plywood
To ensure you get a genuine, high-quality product that provides the best value for your money, follow this practical buyer's checklist before making a purchase.
- Always Insist on the Correct ISI Mark: For BWR grade, the sheet must be stamped with IS:303. For the superior BWP/Marine grade, the stamp must be IS:710. A genuine mark also includes a unique CM/L (license) number.
- Conduct a Thorough Physical Inspection: A good quality waterproof plywood sheet will have perfectly straight edges, a uniform thickness at all corners, and a smooth surface. Look at the side profile to ensure there are no visible gaps or overlaps between the core layers.
- Assess the Weight: High-quality 18mm waterproof plywood made from dense hardwood veneers will feel noticeably heavier and more solid than a lower-quality sheet of the same size.
- Perform a Simple Sound Test: Tap the center of the plywood sheet firmly with your knuckles. It should produce a consistent, solid, and deep sound. A hollow or varying sound may indicate internal gaps or a poorly constructed core.
- Buy Only from Authorised Dealers: To avoid counterfeit products and to ensure you receive a proper bill and a valid manufacturer's warranty, always make your purchase from an authorized dealer of the brand.
- Clarify the Grade for Your Use Case: Be very specific with the dealer about your needs. If you are building kitchen cabinets, insist on BWR or BWP grade and do not get misled into buying the cheaper MR (Moisture-Resistant) grade, which is not suitable for wet areas.
