Description:
Prized for its striking grain and strength, thermally modified ash rivals the performance of tropical hardwoods. This advanced treatment enhances its resistance to moisture, decay, and warping while deepening its warm tones into rich hues. The result is a stunningly beautiful wood that delivers lasting durability in demanding outdoor environments.


Advantages:
Dimensionally Rock-Solid
212°C heat restructures our Carbonized Ash at the cellular level, slashing moisture absorption. No warp, shrink, crack, or swell - dimensions stay the same for years to come.
Naturally Pest-Proof
Long time 212°C precise heat reforms the wood's internal nutrients. MUMU Carbonized Ash starves fungi and insects to death, providing chemical-free defense against decay and infestation.
Purely Green
Made with only heat and steam. Zero chemicals added. Optional water-based UV coat only. MUMU Carbonized Ash is a clean, non-toxic building material.
Low Effort, Long Life
Annual oiling is all it takes. MUMU thermowood delivers a 15–20 year lifespan with no repainting or harsh chemicals needed.
Made to Measure
Standard size: 4000×135×20 mm. We cut shorter or produce longer lengths to match your exact spec.
Fire Performance Boost
Pre-carbonized at 212°C, so when burned, its ignition is significantly slowed down. No flaming drips, far less smoke. Significantly safer than untreated softwood.
Multi-Purpose Performer
Suits cladding, siding, decking, flooring, sauna, and furniture. Works equally well with modern and rustic design.

| Installation | For a lasting result, it is strongly recommended that the supporting battens be fabricated from stainless steel or equally corrosion-resistant material, with cross-sectional dimensions of 25 mm by 45 mm, and installed at intervals of 600 mm to 1000 mm. Each individual board should then be attached using a minimum of three, and ideally four, rust-proof self-tapping screws. As a critical final step, all exposed end grain and the full rear surface of the boards must be sealed with a protective oil treatment to maximize long-term performance. |
FAQ:
Q1: What is the recommended maintenance for thermally modified wood?
Our Carbonized Ash products are designed for minimal upkeep. If you prefer a completely hands-off approach, simply allow the wood to weather into a natural silvery-grey. To retain the original rich tones, periodically apply a penetrating oil formulated with colourtone pigments.
Q2: Why should I choose painted thermowood over ordinary painted wood cladding?
MUMU Carbonized Ash offers a deeper, more lasting solution. The heat treatment transforms the entire board, not merely the surface. This delivers long-term stability and durability that outperforms conventional painted cladding, which relies on a superficial protective layer.
Q3: When will my order be delivered?
Delivery timelines depend on the product type and order volume. For smaller quantities, we typically ship within 7 to 15 days after full payment is received. Bulk orders generally require approximately 30 days for preparation.
Q4: Can I obtain a free sample?
Absolutely. A complimentary sample is available; shipping costs can be handled either via freight collect or prepaid arrangements.
Q5: Is the production process truly chemical-free?
Completely. The method relies exclusively on a traditional, all-natural process of fire treatment and natural oils, with absolutely no synthetic additives.
Q6: How does carbonized wood compare in strength to regular wood siding?
Thermowood provides significantly greater stability, durability, and resistance to rot and insects. While it is slightly more brittle, it offers superior dimensional strength, resisting warping and shrinkage far better than untreated wood.
Q7: What is the expected lifespan of thermowood?
When properly maintained, you can anticipate 10 to 15 years of reliable outdoor service. Indoor applications typically enjoy an even longer functional life.
Q8: Are custom sizes and finishes available?
Yes. We can tailor the material selection, joinery details, colour, and dimensions to precisely match your design specifications.
