High Silica Glass
High Silica Glass Materials for High-Temperature Protection
High silica glass materials are high-temperature inorganic fiber products with a high silica content, typically around 96% or higher, designed for applications requiring reliable heat resistance, thermal stability, and fire protection.
Our high silica glass range provides excellent thermal protection, low thermal conductivity, flame resistance, and good chemical stability for demanding industrial environments. The materials are available in flexible textile forms suitable for cutting, wrapping, sewing, laminating, and fabrication into customized thermal protection products.
These materials are particularly suitable for high-temperature insulation, welding protection, furnace and kiln protection, heat shields, fire barriers, expansion joints, and other applications where standard fiberglass fabrics may not provide sufficient temperature resistance.
High Silica Fiberglass Fabric for Welding, Insulation and Heat Protection
Our High Silica Glass portfolio provides high-temperature silica-based fiberglass materials for industrial thermal protection and fire-resistant applications. The range includes high silica fiberglass fabric, high silica cloth, woven silica fabric, and related textile forms designed for extreme heat environments.
High silica fabric is produced from specially treated glass fiber to achieve a high SiO₂ content, commonly 96% or above. This composition provides higher temperature resistance than conventional fiberglass fabric and makes the material suitable for prolonged exposure to high heat, flames, sparks, and thermal radiation.
The flexible woven construction allows high silica fabric to be cut, wrapped, sewn, and fabricated into welding blankets, fire curtains, furnace curtains, removable insulation covers, thermal barriers, heat shields, and other custom heat protection components.
Typical applications include welding and hot-work protection, furnace and kiln insulation, pipe and equipment insulation, exhaust heat shielding, expansion joints, fire barriers, molten metal splash protection, and high-temperature industrial protection. High silica glass fiber materials are also used in aerospace, automotive, shipbuilding, metallurgy, petrochemical, power generation, and other industries operating under severe thermal conditions.
Depending on the product construction and treatment, high silica fabrics can be supplied in different weights, thicknesses, weave structures, heat treatments, and surface finishes to meet specific application and temperature requirements.
