When searching for materials like HMR board or HDF board, many homeowners and contractors are actually looking for something more durable, more water-resistant, and longer-lasting performance. This is where HDMR board stands out.
At Rtree, we specialize in advanced water-resistant boards for door designed to outperform traditional materials like HMR. If you’re still considering HMR, here’s what you need to know before making the final decision.
What is HMR Board?
HMR (High Moisture Resistance) board is widely used in interior applications such as cabinetry, doors, and furniture. It offers better moisture resistance compared to standard MDF, making it suitable for areas with moderate humidity.
However, HMR board still has limitations:
- Most HMR in the market is only up to 24 hours swelling test
- Susceptible to swelling under prolonged moisture exposure
- Limited durability in high-humidity environments
What is HDMR Board?
HDMR (High-Density Moisture Resistant) board is an advanced engineered wood panel designed for superior durability, strength, and moisture resistance.
Rtree HDMR board is specifically developed for environments with high-humidity climates like Malaysia.
Key Features of Rtree HDMR Board:
- V313 Water-Resistant Standard – Rtree HDMR Board went through a severe test that subjects boards to repeated cycles of moisture and temperature (3 days of water soaking at 20°C, 1 day frozen at -12°C and 3 days of oven baked, at 70°C. Repeat 3 cycle for 21 days.
- Passed 100-Hour Swelling Test – A performance level not yet achieved in the industry.
- High Density Structure – Stronger and more durable than conventional boards (HMR / HDF), usually exceeds 800 kg/m³ making it heavier and more robust
- Stable & Long-Lasting – Minimizes warping, cracking, and deformation
- Ideal for Doors – Especially at places exposed to high moisture like bathroom or laundry area.
Differences Between Rtree Water Resistant Board (HDMR) and HMR
HDMR vs HMR Board Comparison
Feature | HDMR Board (Rtree) | HMR Board |
Material Type | Finer hardwood fibers and resin are compressed under significantly higher pressure to achieve | Medium to high-density fiberboard (MDF) treated with melamine |
Water Resistance Standard | V313 water-resistant standard. | Basic moisture resistance (no V313). |
Swelling Performance | Passed 100-hour swelling test (industry-leading) | Mostly 24 hours swelling test |
Durability | High durability with long lifespan | Moderate durability |
Density & Strength | Exceeds 800 – 850 kg, making it heavier and more robust. | Generally ranges from 700 – 800 kg |
Warping Resistance | Excellent resistance to warping and deformation | Can warp under prolonged humidity |
Long-Term Value | Better investment due to durability and stability | Lower upfront cost but higher long-term risk |
Fungus Resistance | 2x resistance of conventional HDF & HMR board | Usually low fungus resistance |
Strength & Screw holding | High. Its high-density core offers vastly superior screw-holding power and load-bearing capacity | Moderate screw-holding |
Rtree Water Resistant Board (HDMR) vs. HMR: Which is Better?
If you are choosing between HMR board or HDMR board, the answer is HDMR if you want to build specifically for the door in Malaysia.
While HMR may be sufficient for basic applications, it does not offer the same level of moisture resistant like HDMR. For homeowners, designers, and contractors who want fewer replacements and better long-term value, HDMR board is the smarter investment.
Don’t settle for materials that only meet basic standards. Discover the difference with Rtree water-resistant (HDMR) board and experience higher performance with peace of mind.
