The insulator has an R-value between R-2.5 and R-3.8 per inch, depending on the form of the product. Fiberglass is quite flexible and provides good insulation, although loose-fill products are more ...

First, let’s discuss the most common types of insulation available for attics: fiberglass batts, cellulose, loose-fill fiberglass and spray foam. More options exist, but these four materials make up ...

It contains better insulating qualities (higher thermal resistance to heat flow known as R-value) than traditional fiberglass insulation due to its ability to block conductive, radiant and convective ...

This fiberglass insulation is 3 inches thick, providing an insulation value of R-10. The blanket is nonflammable and has a foil face to reflect as much heat back into the tank as possible.
