When starting a home interior project in Dhaka, you will hear contractors throw around terms like Gorjan Plywood, MDF, HDF, HDMR, and Particle Board. Choosing the wrong core material is the leading cause of warped wardrobe doors, peeling kitchen cabinets, and sagging bookshelves within two to three years. Here is a clear guide to which material belongs in each zone of your apartment.

1. Gorjan & Marine Plywood (Best for Heavy Loads & Wet Zones) Plywood is made by layering real wood veneers glued in cross-grains. It offers the highest screw-holding capacity and resistance to sagging.

• Where to Use: Kitchen sink base units, bathroom vanities, overhead heavy storage, and structural bed frames.
• Best Finish: High-pressure laminate (HPL) or acrylic sheets.

2. High-Density Fiberboard (HDF / HDMR) (Best for High-Wear Areas) HDF is engineered under intense pressure and heat, creating a dense, moisture-resistant panel (800+ kg/m³) that withstands local humidity far better than standard boards.

• Where to Use: Modular kitchen carcasses, tall pantry units, and dinner wagons.
• Best Finish: Acrylic sheets, anti-scratch lacquer, or PU paint.

3. Medium-Density Fiberboard (MDF) (Best for Decorative Wall Panels) MDF has a fine, grain-free surface that cuts cleanly under CNC routers. However, regular untreated MDF absorbs moisture easily and should never be used near water lines.

• Where to Use: Vertical fluted wall paneling, living room TV feature walls, decorative bedroom mouldings, and wardrobe shutter fronts.
• Best Finish: Duco paint, PU lacquer, or natural wood veneer polish.

4. Melamine-Faced Particle Board (Best for Budget-Friendly Dry Areas) Made from compressed wood chips and resin, particle board is lightweight and cost-effective, but has lower load-bearing strength and poor water resistance.

• Where to Use: Shoe racks, non-structural bedroom shelving, internal partitions of dry wardrobes, and study desktop dividers.
• Key Rule: Ensure every exposed edge is sealed with factory-pressed 1mm to 2mm PVC edge banding to lock out air moisture.

5. Material Selection Summary for Dhaka Apartments

• Kitchen & Sinks: Marine Plywood or HDMR with quartz countertops.
• Living & TV Backdrops: MDF for precise CNC grooving and seamless painted finishes.
• Wardrobes & Closets: HDF or commercial plywood for tall shutter doors to prevent bending over time.
