BWP vs MR plywood vs HDHMR: which board for kitchens and wardrobes?

The board inside your cabinets decides how long they last. It is also the easiest place for a quote to save money without you noticing. Here is a plain-language guide to the three boards you will hear about most: BWP plywood, MR plywood and HDHMR.

MR plywood: for dry areas

MR stands for moisture resistant. It handles the normal humidity of a bedroom or living room well, and it is the sensible, economical choice for wardrobes, TV units and other furniture away from water. It is not designed for daily contact with water.

BWP plywood: for kitchens and wet areas

BWP stands for boiling water proof. It is made with stronger, water-resistant bonding, so it holds together where water is a daily fact of life: the sink cabinet, the area around the hob and dishwasher, bathroom vanities and utility units. It costs more than MR, and in these places it is worth every rupee.

HDHMR: smooth, dense and stable

HDHMR stands for high density, high moisture resistant board. It is an engineered board made from compressed wood fibre. It is very flat and smooth, does not warp easily, and takes laminate and acrylic finishes beautifully, which makes it a strong choice for shutters (cabinet doors). It is heavier than plywood and needs the right hardware and precise drilling, which is what factory machines do well.

Side by side

What about particle board and MDF?

Particle board and plain MDF are cheaper and fine for some loose furniture, but they swell if water gets into an edge. We do not use them for kitchen or wardrobe carcasses.

Edges matter as much as the board

Water gets into a board through its cut edges. That is why every edge of a Decorguys panel is sealed with 2 mm PVC edge banding on an edge-banding machine, not by hand on site. Read more in why factory-made interiors last longer.

What Decorguys uses

Every cabinet is built in 18 mm Greenply Ecotec plywood: BWP grade in kitchens and other wet areas, MR grade in dry areas. Shutters are 18 mm HDHMR with 1 mm decorative laminate outside and 0.8 mm inside, 8 mm pre-laminated back panels, 2 mm PVC edge banding and Fevicol adhesives. Everything is cut, edge-banded and drilled by machine in our Bengaluru factory.

Questions to ask any interior firm

• Which board is used for the kitchen box, and which for the shutters?
• What thickness, and which brand and grade?
• Is the sink cabinet BWP?
• Are the edges machine edge-banded on all sides?
• Is the board grade written in the quote and the agreement?

How to check the board you are getting

• The grade and brand should be written in your quote, not just "plywood"
• Boards carry printed marks for grade and IS standard on the face
• Ask to see an offcut: the core should be even, without gaps between layers
• Edges should be sealed with edge band, never left raw

Board and finish go together

The board is the structure; the finish on top is what you see and touch. Laminate is pressed onto the board; acrylic and PU need a smooth, stable base. HDHMR is often chosen for shutters because its smooth face takes these finishes well, while plywood holds screws strongly in carcasses. That is why many good kitchens combine two boards.

Thickness

Carcasses are usually made in 18 mm boards, which hold screws and hinges firmly. Back panels can be thinner because they carry less load. Very large shutters may need thicker boards or a frame to stay straight over time.

Frequently asked questions

Which plywood is best for a kitchen in Bangalore?

BWP-grade plywood for the cabinet boxes, especially the sink and hob areas, paired with a moisture-resistant shutter board such as HDHMR.

Is HDHMR better than plywood?

They do different jobs. HDHMR is excellent for flat, smooth shutters; plywood is excellent for strong cabinet boxes. Many good kitchens, including ours, use both.

Can I use MR plywood in the kitchen to save money?

We do not recommend it for the sink and hob areas. The saving is small compared with replacing a swollen cabinet a few years later.

Is MR plywood good enough for wardrobes?

Yes. Wardrobes are away from water, so MR-grade plywood is the right and economical choice.

Is HDHMR better than plywood?

Neither is better everywhere. HDHMR is smooth, dense and good for shutters; plywood holds screws strongly and is lighter. Many kitchens use both.

What thickness of plywood is used for kitchens?

18 mm for the carcass and shelves is standard; thinner boards are used for backs and drawer bottoms.
