Blown-in Insulation
Blown-in Insulation is typically installed in open attics of both new and existing structures. It can also be used in retrofit closed-cavity applications such as exterior sidewalls or floored attics in existing and older homes. By carfully removing small sections of siding and drilling small holes we can gain accsess to the inteior of your homes wall and blow insulation into it. Cellulose and fiberglass share similar R-values at normal temperatures (R-value 3.2 per inch) but cellulose has greater insulating properties at lower temperatures than fiberglass or mineral wool making it the better insulation choice in the colder climates. Cellulose is also less permeable to air movement than fiberglass and is less affected by packing and fluffing, making it a better insulation for blowing into uninsulated walls or other building cavities. Studies at the University of Colorado confirmed that cellulose is indeed the insulation of choice for walls and ceilings. Installation of a vapor barrier is essential with fiberglass insulation, which is why blowing loose-fill fiberglass insulation into existing walls is not advisable. This is because fiberglass insulation soaks up water like a sponge, causing a pronounced drop in its insulating ability.
-
Cellulose insulation manufactured from recycled paper is the
least polluting
and
most energy
efficient
insulation among conventional insulation products—least polluting at the time of
manufacture
and during demolition and
disposal
as waste.
-
It takes more than 10 times as much
energy to produce
fiberglass insulation as cellulose insulation. (Cellulose is a natural fiber. Fiberglass fibers are made from glass.)
-
Due to air circulation and natural convection, the
R-value
of blown-in
fiberglass
insulation
decreases by as much as 50%
as the temperature drops from 45 degrees F to 18 degrees F.
-
Cellulose has
better resistance to air flow
and prevents the upward movement of air caused by temperature differences (the R-value of
cellulose actually improves
during cold weather).
-
Substantial and well-documented public
health threats
are associated with fiberglass.
-
No adverse
health effects
from cellulose insulation have been identified. Fiberglass harms lungs.
