Frequently Asked Questions

Q: What does R-value mean in insulation?

A: The R-value of an insulating material refers to how well it prevents the flow of heat. The higher the R-value, the more effective a material is as an insulator. The R-value of insulation is typically expressed per inch of material thickness.

Q: Does fiberglass insulation burn?

A: No. Fiberglass is nonflammable and doesn’t burn. If it’s exposed to an open flame or reaches a high enough temperature, it will simply melt. However, if backing materials such as foil or paper are attached to fiberglass insulation, they may burn.

Q: What is an electrical insulator?

A: An electrical insulator is a material that doesn’t let electrical impulses pass freely through it. Electrical insulators may be used to coat wires or cables to prevent electrical shocks. Effective electrical insulators include:

  • Rubber
  • Glass
  • Air
  • Plastic
  • Fiberglass
  • Porcelain
  • Quartz
