Plywood FAQ - Grades, Uses & Buying Guide
Everything about plywood grades, marine vs BWR vs MR, thickness, waterproofing, prices and uses - answered by Navkar Plywood, an Ahmedabad manufacturer & supplier.
Quick Answers
What is marine plywood?
Marine plywood is a high-grade, boiling-water-proof (BWP / IS:710) plywood bonded with phenol-formaldehyde resin. It resists water, humidity, borers and termites, making it ideal for kitchens, bathrooms and outdoor furniture. Navkar manufactures 710 marine plywood in 6-19 mm for Ahmedabad and Gujarat.
What is BWR plywood?
BWR (Boiling Water Resistant) plywood is graded to IS:303 and bonded to withstand moisture and humid conditions. It is stronger against water than MR grade and suited to kitchens, furniture and semi-exposed interiors. Navkar BWR-303 ply is borer and termite treated for long service life.
What is MR grade plywood?
MR (Moisture Resistant) plywood, graded to IS:303, resists humidity but not prolonged water contact. It is the economical choice for interior furniture, wardrobes and dry-area cabinetry. Navkar MR ply offers a smooth, calibrated surface ideal for lamination.
Which plywood is best for furniture?
For most interior furniture, BWR-grade plywood offers the best balance of strength, moisture resistance and value. For kitchens, bathrooms and wet areas, choose 710 marine (BWP) plywood. MR grade suits budget dry-area work. Navkar supplies all three grades in Ahmedabad.
Which plywood is waterproof?
710 marine-grade (BWP) plywood is the most waterproof, made to IS:710 with phenolic bonding that survives boiling water. BWR (IS:303) is water-resistant but not fully waterproof. For genuinely wet areas, use 710 marine plywood.
What is the difference between BWR and MR plywood?
BWR (Boiling Water Resistant) plywood withstands moisture and humidity far better than MR (Moisture Resistant), which only resists humidity, not standing water. BWR suits kitchens and semi-wet areas; MR suits dry interior furniture. Both are IS:303 graded, but BWR uses a stronger water-resistant adhesive.
Grades & Standards
Is marine plywood the same as 710 plywood?
Yes. "710" refers to IS:710, the Indian standard for boiling-waterproof (BWP) marine plywood, so the terms are used interchangeably.
What does IS:710 mean on plywood?
IS:710 is the BIS standard for boiling-waterproof plywood - phenolic-bonded ply that survives boiling water, used for wet and outdoor areas.
What does IS:303 mean?
IS:303 is the BIS standard covering MR (moisture resistant) and BWR (boiling water resistant) grade plywood for interior and humid-area use.
Is BWR plywood waterproof?
BWR is highly water-resistant for humid and semi-wet areas but not fully waterproof. For constant water contact use 710 marine (BWP) plywood.
What is gurjan plywood?
Plywood made with Gurjan (keruing) hardwood face and core - dense, strong and a premium choice for furniture.
What is calibrated plywood?
Plywood sanded to a precise, uniform thickness, giving a smooth, even surface that is ideal for lamination.
What is fire-retardant plywood?
Plywood treated with fire-retardant chemicals that slow ignition and flame spread, used where fire safety matters.
How is plywood graded for strength?
By IS standards (IS:303, IS:710), ply count, core species, bonding quality and calibration.
How do I verify genuine BWP plywood?
Check the IS:710 marking, brand stamp and bonding quality, and buy from authorised suppliers like Navkar.
What glue is used in marine plywood?
Phenol-formaldehyde (phenolic) resin, which gives boiling-waterproof bonding.
Choosing & Using Plywood
Can MR plywood be used in kitchens?
Not ideal - MR resists humidity, not standing water. For kitchens choose BWR or 710 marine plywood.
Which plywood is best for a modular kitchen?
BWR-grade for general units and 710 marine for sink and wet zones - both resist moisture far better than MR.
Which plywood is best for wardrobes?
MR or BWR grade in 16-19 mm. BWR adds humidity protection; MR is economical for dry bedrooms.
Which plywood is best for bathrooms?
710 marine (BWP) plywood - it is boiling-waterproof and survives constant moisture.
Which plywood for office furniture?
BWR or commercial grade in 18 mm for desks and storage; MR for dry, low-use units.
What thickness of plywood for a wardrobe?
16-19 mm for the carcass and shutters, and 6-12 mm for back panels and partitions.
What thickness for kitchen shutters?
Typically 18 mm for strength and to hold hinges and laminate well.
What sizes does plywood come in?
The standard sheet size is 8 x 4 ft (2440 x 1220 mm); thicknesses commonly range 4-19 mm.
Can plywood be used outdoors?
Only boiling-waterproof 710 marine plywood is suited to outdoor or exposed use; other grades are for interiors.
How to maintain plywood furniture?
Keep it dry, wipe spills quickly, avoid prolonged water contact, and protect surfaces with laminate, veneer or polish.
Does plywood warp?
Quality cross-bonded plywood resists warping; poor bonding or constant moisture can cause warping over time.
How long does marine plywood last?
Quality 710 marine plywood can last decades, thanks to phenolic bonding and borer/termite treatment, even in damp areas.
Plywood vs Other Materials
Is plywood better than MDF for furniture?
Plywood is stronger, lighter and more moisture-tolerant; MDF is smoother for paint and routing. For load-bearing furniture, choose plywood.
Is plywood better than blockboard?
For long panels like doors and shelves, blockboard resists sagging; for general furniture, plywood gives better all-round strength and screw-hold.
What is MDF board used for?
Modular furniture, CNC routing, painted panels, wardrobes and surfaces needing a smooth finish.
Is MDF waterproof?
Standard MDF is not waterproof - use HMR (moisture-resistant) MDF for damp areas, or plywood.
MDF vs HDF - what is the difference?
HDF is denser, harder and stronger than MDF; MDF is easier to machine and more common for furniture.
What is blockboard used for?
Doors, shutters, long shelves, tables and partitions where a long, lightweight, sag-resistant panel is needed.
Is blockboard waterproof?
BWR-grade blockboard resists humidity; standard blockboard is for dry interiors. For wet areas use marine plywood.
What is veneer and how is it applied?
Veneer is a thin slice of natural wood glued onto plywood or MDF, then polished or coated for a real-wood finish.
Natural veneer vs laminate - which is better?
Veneer gives a premium natural-wood look; laminate is more durable and lower maintenance. Choose by look versus wear.
How thick is a laminate sheet?
Decorative laminates are usually 0.8 mm or 1 mm; thicker compact grades also exist.
What is the difference between 1mm and 0.8mm laminate?
1 mm is thicker and more durable for high-wear surfaces; 0.8 mm is economical for verticals and low-wear areas.
Doors, Treatment & Eco
What is a flush door made of?
A timber or block-board core faced with plywood or veneer, pressed into a flat, smooth door.
Solid core vs hollow core flush door?
Solid core is heavier, stronger and better at sound insulation; hollow core is lighter and economical for internal doors.
Is Navkar plywood termite resistant?
Yes - our plywood is treated against termites and borers using vacuum pressure impregnation (VPI).
Is Navkar plywood borer-proof?
Yes, the core and veneers are chemically treated to resist borer attack.
Is plywood eco-friendly?
Plywood from sustainably managed forests is a responsible engineered-wood choice; look for low-emission (E1/E0) grades.
