REFRASIL® Needle Blanket Insulation
 

 

 

 
High Temperature Insulation Blankets made from Silica, Basalt, and Glass Fibers for your Thermal & Acoustic Challenges:

The REFRASIL® textile family includes a series of needled insulation blankets manufactured from a variety of fibers to meet your thermal and acoustic insulation requirements.

Our needled blanket products are recommended as cost-effective, health friendly, thermal solutions for temperatures ranging from 1100 °F to 2100 °F. These insulation blankets are manufactured from:
  • High purity silica (99% silica) for temperatures up to 2100 °F
  • Silica (93.5% silica) for temperatures up to 2000 °F
  • Silica/Basalt blend for temperatures up to 1800 °F
  • Basalt for temperatures up to 1500 °F
  • Silica/Glass blends for temperatures up to 1500 °F
  • Glass for temperatures up to 1100 °F

 
Our silica-based blankets are also  available in pre-shrunk versions to eliminate in-situ shrinking (less than 0.7% shrinkage at 2000 °F).

The low shrinkage blankets are also 3-4 times stronger than typical RCF blanket.
Our blankets offer several advantages over competing blanket insulation materials such as:
  • Zero shot content (blanket contains no un-fiberized particles)
  • Non-respirable (fiber diameter between 6 - 13 microns)
  • Binder free
  • Chemical resistant (silica and basalt blankets)
  • Contains no asbestos
  • Contains no ceramic refractory fiber (RCF)
  • High strength
  • Vibration resistant
  • Erosion resistant
  • Excellent acoustic properties (sound adsorption)
  • Non water soluble
