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.
