Features & Benefits

Advantages
  • The borosilicate glass fibers that make up Microlite insulation are noncombustible and non-hygroscopic.
  • Microlite does not support fungi or vermin.
  • Microlite is unaffected by oil, grease and most acids.
  • The high tensile strength inherent in Microlite blankets helps the product resist damage during fabrication and installation.
  • Because of their resiliency, high tensile strength and flexibility, Microlite blankets resist settling, breakdown, sagging from vibration, shakedown and damage from impact.
  • Microlite equipment insulation forms easily around corners and curved surfaces and is readily cut in die-cut presses or with a knife.
  • Microlite is compression packaged to significantly reduce volume.
  • The result is potential savings in both freight costs and storage.
  • The countless air spaces in Microlite create effective sound absorption as well as thermal properties.
  • Perceived noise from air movement and mechanical equipment is noticeably reduced.
