Foam insulation is easier to work with than other forms of insulation and is relatively affordable.
In
many regions of our country, winter is already beginning to set in. If
you haven't done so already, now is the time to prepare your home to
combat the harsh winter elements. One of the greatest ways to increase
the energy efficiency of a building is to install proper insulation.
There
are many different choices when it comes to shopping for your
insulation; to help make your decision a bit easier, we've outlined a
few of the most commonly used. As part of our research, we consulted
the EERE Consumer Guide.
- Foam. Foam insulation
is quite popular. It is sprayed into the walls, ceilings, and floors.
It is easier to work with than other forms of insulation and is still
relatively affordable.
- Fiberglass. Fiberglass
insulation is one of the most commonly used. It is made of very fine
glass fibers. It comes in batts or loose-fill. There are different
densities of fiberglass insulation, measured by R-value. The density is
chosen based upon the building code, the climate where the building is
located, and the location of the insulation.
- Soy Batting. Soy
insulation is made out of soy based materials. It comes both in batts
and spray-on foam, and is preferred because it is void of harmful
formaldehydes and other toxic chemicals. It is also resistant to molds
and mildews, and is just as effective other products.
- Mineral Wool. Mineral wool insulation can be divided into two categories, rock wool and slag wool.
- Rock wool is made out of natural minerals such as basalt and diabase.
- Slag wool
is made out of furnace slag, the scum that forms on molten metal.
Mineral wool products can be considered more eco-friendly, as they
contain an average of 75% recycled content. They come in batts and
loose fill.
- Plastic Fiber. This
insulation is made mostly from recycled plastic milk bottles. These
polyethylene terephthalate fibers come in batts. Unlike fiberglass
insulation, which is very uncomfortable to work with, plastic fiber
insulation is non-irritating.
- Natural Fibers. For the more health conscious individuals, there are several options of natural fiber insulations available. Cotton, sheep's wool, straw, and hemp are all used as insulation.
