Plywood is the hidden part of every cabinet, and the grade decides how well it survives water and humidity. Here is what BWP, BWR and MR mean, and where to use each in a Pune home.
The three common grades
| Grade | What it stands for | Water resistance | Use it for |
|---|---|---|---|
| BWP | Boiling Water Proof (often sold as marine grade) | Highest | Kitchen sink base, bathroom vanities, anywhere water can collect |
| BWR | Boiling Water Resistant | Good | Kitchen cabinets, utility areas, wardrobes on damp walls |
| MR | Moisture Resistant | Basic | Bedroom wardrobes, TV units and other dry areas |
Where to use what
- Kitchen sink base: BWP. This is where leaks happen, and replacing a swollen cabinet costs more than the upgrade.
- Rest of the kitchen: BWR at least.
- Bedrooms and living room: MR is usually enough, unless a wall is damp or shared with a bathroom.
How to check what you're getting
- Ask the firm to write the grade, brand and thickness for each unit in the quote.
- Check the marking stamped on the sheets when they arrive on site.
- Compare it with the quote before you approve the materials stage. BookInterio's Quality Auditor does this check for you.
Watch out: a quote that just says "commercial plywood" or "plywood" without a grade leaves room for a downgrade. Ask before you sign.
