Fire Protection, Heat & Sound Insulation

  • If you are interested in better fire protection and 150 C higher heat resistance than with E-glass materials but less expensive than silica, you need fabrics from our basalt fiber.
  • If you need reliability, you will get it using materials made of our basalt fiber.
  • Our advanced basalt fibers have 15-20% higher tensile strength and tensile modulus, better chemical resistance, and an extended operating temperature range compared to regular E-glass. KV’s basalt performance is close to that of high strength and corrosion resistant fibers but at a more attractive price.

  • Basalt fibers have better sound insulation properties than glass fibers. Hence, with interior based on basalt fiber you will feel yourself more comfortable.
  • The dielectric properties of basalt fibers are equal to ones of glass fibers. So, switch from glass to basalt does not change radar transparency of construction.
  • After exposition under 400°C the basalt fibers lose only 20% of their initial strength, while strength of E-glass under the same conditions drops substantially - more than 50%.
  • Kamenny Vek can provide various types of yarns and woven fabrics. We are open for collaboration in the manufacturing of specially designed fabrics and braided sleeves. Our R&D team is ready to satisfy your toughest requirements.
