Viroc is a composite material, composed by a compressed and dry mixture of pine wood particles and cement. It combines the flexibility of wood with the strength and durability of cement, allowing a large range of applications, both indoor and outdoor. Viroc presents a non-homogeneous appearance, a product natural feature. Viroc can be factory calibrated/sanded (for applications requiring tighter tolerances).Once calibrated, presents visible wood particles on the surface. Thickness sanded (mm):8, 12, 15, 18, 21, 24and28. Dimensions: 2600x1250mm/3000x1250mm, other dimensions under request. Color: black, grey, white, yellow, red, Ocher Advantages Non toxic Does not contain dangerous volatile compounds and is free of silica, asbestos and formaldehyde. Sound insulation It has good sound insulation properties due to its high weight. The sound insulation index varies according to board thickness. Airborne sound resistance is 31 or 37 dB depending on whether board thickness is 8mm or 22mm, respectively. Weight resistant The board has a bending strength that enables it to be used as resistant structural element. It is therefore used in flooring and as roof support. The bending strength is 9N/mm2 with a modulus of elasticity of 4500 N/mm2. Easy installation It can be cut, drilled and sanded. The tools and fastening systems used for Viroc boards are identical to those used with wood. Fire retardant It prevents the spread of fire. According to the ignitability test conducted, it is classified as B-s1, d0 in accordance with EN 13501-1. Moisture resistant Under the action of water it does not disaggregate. It is a material impermeable to water. Thermal insulation It has good thermal resistance properties, meaning that it can function as insulation in both cold and hot temperatures. Insect resistant It will not degrade with the action of living organisms such as fungi, termites or any kind of insects. Applications The Viroc board is used for structural or covering functions. It may be applied on wood or metallic supporting structures. It can be used in the following applications due to its versatility: *Facades *Partition walls and walls cladding *Flooring *Suspended ceilings *Roof supports *Lost formwork *Interior design *Urban equipment Quality and certifications CE Certification The Viroc product obtained authorization to the CE marking in 2004, according to the European standard EN 13986. The CE certification guarantees the performance of several features of the Viroc board, enabling its use indoors and outdoors: *Modulus of elasticity *Bending strength *Durability *Fire reaction *Water vapor resistance *Sound absorption *Thermal conductivity *Impact Resistance *Mechanical durability *Resistance to biological agents ICC Evaluation Service Certification The ICC certification ensures performance of the Viroc board in the areas of: *Fire Performance *Control of sound transmission *Conductivity and thermal resistance *Outdoor coverings *Structural performance Underwriters Laboratories (UL Certification) Underwriters Laboratories is an independent organization for the safety certification of products. Viroc ceiling and floor systems are tested and certified by UL for fire resistance.
