Cement-bonded board / CSP in Yerevan

Cement-bonded boards / CSP or CSP boards are a versatile building material made from Portland cement, wood chips, and mineral additives. Thanks to the combination of cement’s strength and wood’s flexibility, CSP boards offer high resistance to moisture, fire, mechanical stress, and biological effects. These properties make the material widely used in both private and commercial construction, as well as in industrial production.

Our company offers the opportunity to purchase CSP boards in Yerevan at a competitive price. All supplied construction materials are certified and meet established quality standards. We provide both wholesale and small-batch deliveries, as well as organize shipping to other regions.

What are CSP boards made of?

CSP boards are made from a mixture of Portland cement, wood chips, and mineral additives. Cement acts as the main binder, providing strength and moisture resistance. Wood chips serve as a reinforcing filler, increasing flexibility and reducing brittleness. Mineral components stabilize the composition, protect the wood from decay and cement interaction, and improve fire resistance.

The core of the board consists of coarse and medium-sized wood chips, impregnated with mineral components and compressed under high pressure. This process creates a uniform structure, a smooth surface, and stable dimensions. Unlike many wood-based sheet materials, CSP boards do not deteriorate on contact with water, do not warp, and maintain strength even after long-term use in humid environments. The material is non-combustible, significantly enhancing the fire safety of structures.

Eco-friendliness: Free of phenol-formaldehyde resins, safe for household use.

Main features of CSP boards: High moisture resistance. Fire resistance. Strength and durability. Frost resistance. Do not warp or burn. Resistant to mold and mechanical damage. Easy to saw and suitable for plastering, painting, and tiling. Compatible with most finishing materials, including plaster, paint, tiles, and decorative panels.

Applications

Cement-bonded boards / CSP are widely used in frame construction. They are used to clad exterior walls, creating a rigid building envelope while providing additional thermal and sound insulation.

The material is suitable for ventilated facades and cladding low-rise buildings. Due to their high moisture resistance, CSP boards are used for formwork, partitions in wet rooms, stair risers, subfloors, technical rooms, and utility areas.

Inside buildings, the boards are often used as a universal structural and finishing material: leveling walls, creating bases for decorative finishes, mounting partitions, and producing decorative elements.
