We prioritize quality and craftsmanship in every wood-cement board we produce. Each board is meticulously crafted to replicate the intricate details and textures of natural wood, offering a high-end solution for wall cladding, ceilings, and other architectural elements.

Advantages Of Wood-Cement Board

Wet And Dry Rot Resistance

The boards are used for interior and exterior applications and in moist conditions such as ceilings in indoor swimming pools.

Termite And Vermin Resistance

Tests have proven that is not vulnerable to attack by termites or vermin, nor is subject to any biological decay.

Thermal Insulation

Due to its relatively low density, has good thermal properties. The maximum thermal conductivity for boards of 25 mm thickness is 0.090 W/mK. For 2- or 3-layer composite panels, the thermal conductivity will be further reduced, when a core of respectively rigid foam (e.g. polystyrene) or mineral fiber has been applied.

Excellent Acoustic Performance

Unfinished (or spray-painted) has very good acoustic absorption properties since the open surface structure allows for a high level of sound absorption.

Wide Application of Wood Cement Board in the Market

Wood-cement boards are exterior and interior building materials manufactured utilizing wood and cement. Fire resistance, freeze-thaw resistance, termite & vermin resistance, wet & dry rot resistance, and thermal insulation are the main characteristics offered by these boards. They are widely utilized in non-residential applications such as gymnasiums & swimming pools due to their sound absorption properties & acoustic performance. Wood-cement boards accept a wide range of conventional plastering, mastics, and decorative materials. Wood strand cement boards (WSCB) are less susceptible to severe weathering, insect attack, and fungal growth when compared to oriented strandboard (OSD) & plywood; it exhibits structural strength and good durability.

The increasing demand for durable & energy efficient economic housing is the primary factor that drives the wood-cement boards market globally. Growing urbanization, increasing disposable incomes, and rise in the number of construction activities are the other factors that supplement market growth. High costs of wood siding grades, stringent government regulations associated with the cutting of trees, and maintenance are some of the factors that may limit the market growth. However, the rising demand from emerging economies such as China & India and product development will provide potential opportunities for market expansion.

Method of Manufacturing a Wood-Cement Board

The present relates to a method of manufacturing a wood-cement board comprising mixing 30 to 40% by weight of cement material, 20 to 27% by weight of wood flake, and 30 to 40% by weight of fly ash to prepare a raw material mixture, strewing said raw material mixture on a mold panel to form a mat, pressing and pre-curing said mat with moisture, and main-curing said pre-cured mat in an autoclave. Said cement material used in the present is such as Portland cement, blast furnace cement, silica cement, alumina cement and the like. Fly ash is added to said cement material to supply silica component. Said fly ash has a fine particle size so that said fly ash has a big surface area for reaction and accordingly said fly ash has a high activity of curing reaction.

Further, fly ash has a substantially sphere shape to improve flexibility of the resulting mat of the raw material and the resulting wood cement board by the ball bearing like action. The preferable particle size of said fly ash is selected so that less than 10% by weight of fly ash may remain on sieve whose opening is 150 μm. Preferable size of said wood flake is such that whole wood flake passes through the sieve whose opening size is 10 mm and has an average size which can pass through the sieve whose opening size is 4.5 mm and a thickness less than 1 mm. Said cement material, wood flake, and fly ash are mixed together to prepare the raw material mixture and 30 to 40% by weight of said cement material, 20 to 27% by weight of said wood flake and 30 to 40% by weight of said fly ash are contained in said raw material mixture.When said fly ash is contained in an amount less than 30% by weight, silica component becomes insufficient for calcium component and the curing reaction cannot be proceeded smoothly and when said fly ash is contained in an amount beyond 40% by weight, bending strength of the resulting wood-cement board becomes lower and the dimension stability of the resulting wood cement board becomes inferior. Further when said wood flake is contained in an amount less than 20% by weight, the reinforcing effect of said wood flake becomes not remarkable and when said wood flake is contained in an amount beyond 27% by weight, the flammability of the resulting wood-cement board becomes inferior.

Said raw material mixture is strewed on a mold panel without adding water in the dry method or in the semi-dry method water is added to said raw material mixture so that the water content of said raw material mixture may be less than 50% by weight and then said raw materials mixture is strewed on a mold panel to form a mat. Said resulting mat is pre-cured by pressing and heating and after then said pre-cured mat is separated from said mold panel and main-cured in an autoclave. Said pre-curing process is carried out at a pressure in the range between 40 to 80 kgf/cm2, a temperature in the range between 70° to 90° C. for 13 to 17 hours and said main curing process in the autoclave is carried out at a temperature of the saturated aqueous vapor in the range between 140° to 165° C. for 7 to 10 hours. When said mat is formed by the dry method, water is supplied to said mat as vapor or mist during said pre-curing process. In the present invention, since fly ash having fine particle size and high reaction activity is added in the raw materials as a silica component and further the main-curing process in the autoclave is carried out, said mat is smoothly cured and curing reaction is substantially complete after main-curing process. Further said main curing process is carried out at a temperature of the saturated aqueous vapor lower than 165° C., the heat deterioration of wood flake during curing process is prevented. Still further since said fly ash has substantially sphere shape, said fly ash gives the resulting mat or the resulting wood cement board a flexibility by the ball bearing like action, cracking or breaking of said mat or said wood cement board is prevented when said mat or said wood cement board is main-cured and separated from the mold panel.

Important Considerations In Use Of Wood-Cement Board

Wood-cement board can be produced in densities ranging from 280 kg/m3 up to 1400 kg/m3. This allows for a wide range of applications depending on the required properties of the product. Low density material is used for insulation of sound and temperature, medium density material is applied more structural as the higher density also gives higher bending strength than the low density material. In situations where one needs the qualities of the low density material for walls, the structural strength of the building has to come from reinforced concrete, steel or wood framing. The medium density boards have specific applications that make it a fire and vermin/termite resistant competitor to conventional boards currently used in stick build construction.

Depending on the construction and local conditions it is now possible to build all types of well insulated housing with wood wool cement board from 3.5 cm thick for moderate climates to walls up to 60 cm thick for extreme cold or hot climates. Especially the use of the thicker low density WWCB material results in very substantial reduction of energy cost for air conditioning and/or heating while the indoor living climate is strongly improved because these walls are breathing. They absorb heat and moisture and release it gradually over a 24-hour period.
