Even better in the cold
Cellulose has a higher initial R-value
than fiberglass, but there's more.
Recent tests have proven that convection
causes fiberglass to lose as much as 40%
of its R-value in cold weather. Air
movement inside the insulation from the
warm side to the cold side results in
heat loss. Cellulose's shorter, natural
fibers form a highly efficient thermal
barrier to virtually eliminate
convection. With a higher initial
R-value that stays high in even in the
coldest weather, Cellulose is clearly
the better insulation choice. |
