In
colder countries of the world, people have discovered several ways to be
comfortable in their homes using materials to heat them up. They have
discovered the many insulation materials after so many years. Some are
man-made, some are natural and some are hybrids. People chose what fits their
needs.
The
materials are as different as they all are from one another. The only likeness
is that they all work the same way – preventing heat from moving around places,
outside or inside, and keep things where they are needed. In houses and
buildings, heat is conserved during winter, and is driven out during summer.
Insulators
Today,
there are foam boards that are rigid and trap the air in controlling heat flow
within a place. Reflective foils deflect radiant sun’s heat (resulting from the
direct rays) to cool the living spaces.
Aside
from these, there are several other materials that are very good in managing
heart and cold in residences and buildings. (The not so popular insulation materials
include vermiculite, phenolic foam, perlite and cementitious.)
The
following popular materials (not in the order of consumer preference) have
their own unique characteristics chosen by home owners and contractors. Their
choices are all dictated by the present needs of the project, price, and some
compromises.
Fiberglass
This
is one the main favorites in insulation materials in that it delivers and that
it is readily available. It is made from recycle glass and made into fibers
used in blankets (batts and rolls) and as loose-fill. They are also used as
rigid boards and duct insulation.
The loose
fill are used with insulation-blowing machines (for attics and closed cavity
applications). They are also used in blown-in blanket systems.
Mineral Wool
This
other favorite has two types – rock wool and (man-made from natural minerals)
and slag wool (made from by-products in blast furnaces). Both of these are 75%
recycled. Also, they are fire-resistant.
These
are usually made into batts and rolls as well as loose-fill insulation
materials.
Cellulose
Basically,
the materials are made from recycled newsprint paper. During the recycling
proves, the makers usually put in borate, sometimes with ammonium sulfate, to
make it fire and insect-resistant.
This
material is usually the choice in new homes and in attic installations as
loose-fill. The dense-packed filling is used in stuffing up cavities in walls
and ceilings.
Plastic Fiber
Made
from recycled plastic (PET) bottles, they are used as batt installation like
the high-density fiberglass. It is treated with a fire retardant, although it
melts when exposed to flame.
Compared
to fiberglass, it is non-irritating to work with. As batts, they are slightly
difficult to work, however.
Cotton
This insulation
material is actually made of 85% recycled cotton and 15% plastic fibers treated
with borate. (Some use the trimmed wastes from recycle blue jeans.)
It
uses minimal energy to make because it is recycled. It is also non-toxic (it’s
a natural fiber) and is available as batts.
Sheep’s Wool
These
days, more materials are coming up to be manufactured into insulation materials. Some turn out to be good and some are failed experiments and
discontinued.
