Plywood Fundamentals · Classification
Types of Plywood: A Complete Classification Guide
"Types of plywood" can mean grade, core species, feature or thickness — buyers often mix these up, which is exactly why mismatched sheets end up in the wrong application.
The Moisture-Resistance Ladder
| Grade | Bonding | Best For |
|---|---|---|
| MR (IS 303) | Urea-formaldehyde resin | Dry interior furniture — wardrobes, cabinets, general carpentry |
| BWR | Enhanced resin, mid-tier moisture handling | Semi-humid areas between MR and full waterproof needs |
| BWP / Marine (IS 710) | Phenol-formaldehyde resin, 72-hr boiling test | Kitchens, bathrooms, sustained moisture exposure |
| Commercial | Interior or exterior grade urea/phenolic bonding | General-purpose furniture and construction use |
Specialty Types
Fire Retardant
Chemically treated to slow flame spread — recommended for commercial spaces, offices and high-occupancy interiors.
E-0 Emission
Uses low-formaldehyde adhesive, meeting the strictest indoor air quality standards — a growing preference for bedrooms and children's furniture.
Calibrated
Sanded to a precise, consistent thickness across the whole sheet — essential for laminate press work and factory-made modular furniture.
Gurjan / Hardwood Face
Denser face veneer species used for premium appearance and added structural strength over standard poplar-faced sheets.
Two More Ways to Classify
Core species (softwood/poplar, hardwood/eucalyptus, or gurjan) affects weight, strength and cost — see our what is plywood guide for the full breakdown. Thickness runs in a standard ladder — 6, 9, 12, 16, 19 and 25mm — with the right pick depending entirely on the application, from drawer bottoms at the thin end to structural flooring support at the thick end.
Why Plywood Beats Solid Wood for Most Furniture
Regardless of type, plywood's cross-grain layered construction gives it real advantages over solid wood: better resistance to warping and shrinking across humidity changes, more consistent strength in every direction, and significantly lower material cost for the same structural performance. See our plywood vs solid wood comparison for the full picture.
Frequently Asked Questions
What are the main types of plywood available in India?
The main classifications are by grade (MR, BWR, BWP/Marine, Commercial), by feature (fire retardant, E-0 emission, calibrated), by core species (softwood, hardwood, gurjan) and by thickness (6-25mm) — each answering a different question about the sheet.
How many grades of plywood are there?
There are broadly four moisture-resistance grades — MR, BWR, BWP (Marine) and Commercial — though Commercial can itself be interior or exterior grade depending on the bonding used.
Which type of plywood is best for a kitchen or bathroom?
BWP or Marine grade is recommended for these high-moisture rooms — see our BWP plywood guide for the full reasoning.
How do I decide what thickness of plywood I need?
Match thickness to load and application — thinner sheets (6-12mm) for panelling and drawer bottoms, 16-19mm for cabinet carcasses and furniture, 25mm for structural or flooring support.
What makes gurjan-faced plywood different from standard plywood?
Gurjan is a denser hardwood veneer species used for the face layer, giving the sheet a premium appearance and added structural strength compared to a standard poplar-faced sheet of the same grade.
