The process of manufacturing fiberglass insulation gives it the ability to resist heat flow. The fiberglass fibers trap pockets of air, slowing the movement of heat through it. When installed in a building, fiberglass helps keep conditioned air inside and can decrease heating and cooling costs as a result.

What are the pros and cons of fiberglass insulation?
In addition to energy savings, fiberglass insulation can also help with noise reduction. Although fiberglass has a satisfactory R-value if it’s not professionally installed, it can lose thermal protection over time.
Why is insulation pink?
The company began adding red dye to the naturally tan or yellowish insulation to distinguish it from their rivals’ products.

Why is fiberglass insulation black?
As mentioned, loose fill insulation like fiberglass becomes discolored when it filters the air leaking from your house. While it might not be immediately noticeable, over time the air leaking from your house carries dust, other particles and moisture, which is what ultimately turns the fiberglass insulation black.
What happens if fiberglass insulation gets wet?
Glassfiber insulation is made from strands of glass fiber and temporarily loses its thermal resistance when it gets wet. However, if it can dry out and has not become compacted, it will retain its insulating properties. Wet insulation in a wall will migrate to the bottom soaking the wallboard and framing materials.
Does black mold grow in insulation?
Technically, mold does not typically grow on the insulation itself. Fiberglass is not a viable food source for mold. Yet mold growth is often found on the top surface of attic insulation.

For the manufacture of insulation, the glass is heated until it can be extruded into fibers of very small diameter.
