Fiberglass

  • Fiberglass insulation is composed primarily of natural ingredients such as sand and recycled glass products that are melted and spun to create tiny strands of fiberglass.
  • Fiberglass is the most widely used home insulator, and is also used to reduce noise transfer from room to room. 
  • Fiberglass comes in both batt and blown forms.
  • Anchor Insulation installs fiberglass insulation from Johns Manville, Knauf and CertainTeed.
