Nine Core Features
Mold, insects, damp, flammability and poor screw holding — the classic failures of wood-based boards are solved at the material level.
Class A1 non-combustible. Will not ignite or release heavy smoke — compliant for public and high-rise projects.
The inorganic gypsum matrix offers no nutrients for mold or termites — the root cause of board decay is removed.
Does not swell, soften or leach when exposed to damp — stable through rainy seasons, kitchens and bathrooms.
Dense core holds screws firmly without crumbling or loosening — load-bearing fixings hold on the first pass.
No urea-formaldehyde adhesive. Emission far below the strictest national standard — safe for child rooms, hospitals and schools.
Saw, plane, groove and curve with ordinary woodworking tools — no new equipment, no relearning, complex shapes stay easy.
Low thermal conductivity keeps rooms warmer in winter and cooler in summer, cutting HVAC energy use.
The porous fibre structure absorbs mid- and high-frequency noise, keeping adjacent rooms quiet.
Very low hygroscopic expansion — no warping, cracking or distortion, so finishes stay flat for years.
Products
One inorganic gypsum platform, three options for different project requirements.
Flagship A functional board built on a gypsum matrix reinforced with plant fibre, balancing strength and environmental performance. Our flagship product for partitions, ceilings, feature walls and furniture substrates.
High-strength gypsum-based OSB board made from premium gypsum and plant fibre — a new-generation substrate. Zero formaldehyde release, Class A1 fire performance, resistant to damp, mould and warping, with excellent sound insulation, thermal performance and dimensional stability. The smooth face accepts putty, paint and wallpaper directly, saving both material and labour.
A complete replacement for wood-based fire-retardant boards. One layer is enough — it takes putty directly, eliminating the extra plasterboard layer wood-based substrates need. Class A non-combustible, proven under direct flame, stable when exposed to fire. Moisture resistant, strong and crack-free, and a zero-formaldehyde product.

Comparison
For partitions, ceilings and feature shapes, gypsum-based fibre board solves the old problems in one move.
| Item | Traditional Wood-Based Board | WUMU Gypsum-Based Fibre Board |
|---|---|---|
| Fire rating | Class B1/B2, spreads flame | Class A1 non-combustible, proven under direct flame |
| Mold & insects | Molds and termite damage when damp | Inorganic matrix, nothing to feed on |
| Moisture | Swells, blisters and delaminates | No swelling (expansion < 0.3%), softening or efflorescence |
| Formaldehyde | Urea-formaldehyde slowly off-gasses | Zero added formaldehyde, child-room safe |
| Screw holding | Collapses once damp | Dense core, screw-holding strength 55–60 kg, firm long term |
| Fabrication | Machinable but edges crumble | Saw, groove, curve freely — edges hold |
About Us
Founded in 2022, WUMU Building Materials is a source factory specialising in the development, production and sales of gypsum-based functional boards, located in Jinzhou City, Shijiazhuang, Hebei Province, China.
"Wood-free" is our product philosophy: removing wood removes the root causes of mold, insects, damp, flammability and formaldehyde emission — replaced by a more stable, safer and greener inorganic gypsum composite.
Our boards are used in residential partitions, ceiling features, commercial interiors, schools and hospitals, and we are equipped for export supply under FOB / CIF terms, with OEM and ODM available.

FAQ
The questions we get most. If yours is not here, just ask.
Ordinary gypsum board is brittle, holds screws poorly and handles moisture badly — it is largely limited to flat partitions. Our plant-fibre reinforced version greatly improves screw holding, impact resistance and moisture performance, and can be grooved, curved and shaped.
Yes. Mold and insects feed on the cellulose and starch in wood. Because our board uses an inorganic gypsum matrix, it offers no such food source, so it stays stable even in humid conditions.
Yes. Please contact us for the current MOQ and lead time — we support FOB / CIF terms and OEM production.
