Silica sand, also known as silicon dioxide (SiO₂), is a compound that is in the form of free quartz or a combination of silicates that is found in nature in high quantities and widely used in many industries. Ravaber Bio is an insulation material obtained by melting the locally supplied silica sand at about 1250 ° C and transforming it into fibers. Ravaber Bio does not undergo dimensional deformations such as swelling, blistering or shrinkage even when subjected to heat and humidity. Its water vapour diffusion resistance factor μ = 1 and its declared thermal conductivity is 0,031 ≤ λ ≤ 0,044 W/mK. (at 10˚C).
Ravaber Bio provides maximum insulation by preventing you from problems such as deterioration, decay, mold retention, corrosion and rusting. Insects and microorganisims can not harm Ravaber Bio products. Depending on the product type, the temperature of use is in the range of -50 /+250°C. Noncohesive Bio products can be used up to 500 ˚C. Ravaber Bio products are classified as “A1” group noncombustible materials and are used in the range of -20 + 400 ° C according to the application area.
Ravaber, the only manufacturer that can produce all mineralwool insulation materials under the same roof, offers a wide range of products with new Ravaber Bio according to various application areas. With the usage of international patented phenol formaldehyde free binder, the fibers are stable and standard. Ravaber Bio products are nature-friendly, non-itching and do not create dust.
