ARMATEX® Coated Fabrics
Used for hot or cold side components, ARMATEX® Coated Fabrics resist external elements like moisture, oil, and chemicals, prevent pipe sweating, and keep external heat from affecting chilled equipment.  Manufactured in a variety of colors for color-coding, matching your environment, or indicating safety hazards, ARMATEX® Coated Fabrics are flexible for ease of sewing and offer protection in extreme environments.

  • ARMATEX® SF 17 Ultra Premium, Premium & Industrial
  • ARMATEX® SF 32 & SF 34
  • ARMATEX® SilverStar 10 &  SilverStar 13
  • ARMATEX® TF 14, TF 17 & TF 18
  • ARMATEX® Firestar

HYTEX® 1000-2025 Fabrics
Mid-Mountain offers three styles of HYTEX® 1000-2025 Fiberglass that provide continuous, high-temperature protection up to 1000° • 538°C, and slows the transfer of heat from hot side components.

  • HYTEX® 2025 Premium HT – heat-treated to reduce fraying and improve dimensional stability.
  • HYTEX® 2025 Aluminized – provides an additional barrier to heat and vapors.
  • HYTEX® 2025 Weavelock – treated with a coating to reduce fraying, increase abrasion resistance, and allow for ease of fabrication.

SILTEX® Silica Fabric
The unique properties of SILTEX® Silica Fabrics make them well suited for use in engineered thermal systems. With a continuous operating temperature of 1800°F • 982°C, they are an excellent choice for hot side protection. The high strength and flexibility create a removable insulation system with durability when exposed to high-temperature.

  • SILTEX® 18-UH
  • SILTEX® 36-UH

CERMEX® Needled Blankets and Mats
Comprised of high purity, highly resilient fibers, CERMEX® Needled Blankets and Mats are very efficient as thermal insulation between hot side or cold side layers and remain mechanically stable after exposure to extreme temperatures.

  • CERMEX® MT1000 Fiberglass Needled Mat
  • CERMEX® BK1800 Silica Needled Blanket


  • Removable insulation pads/blankets
  • Pipe insulation covers
  • Valve jackets
  • Trap insulation
  • Turbine blankets and reactor blankets
  • Tank insulation blankets


  • Improved operational efficiency – easily accessible and serviceable, allowing for ease of maintenance/inspection and quick reinstallation.
  • Personnel Protection – reduces the touch temperature of components, and reduces the ambient air temperature, providing a more comfortable work environment.
  • Sound Attenuation – reduces the decibel exposure to personnel to comply with OSHA safety regulations.
  • Energy Conservation – immediate reduction of energy usage following installation, assisting facility managers with their energy performance goals.
