By administrator On March 3rd, 2009

Insulation for your home has a direct effect on your finances and home maintenance costs. If you are planning a remodel – any remodel… kitchen, attic, or basement; you need to take a look at your existing insulation and see if it is still doing the job.

Today there are many green insulation options available that use recycled materials. Moreover our choices are no longer restricted to foam and fiberglass. There are other materials that pose no risk to those with allergies. When selecting insulation material you need to consider its insulation performance or R-value. In the US, exterior walls are expected to have a value of at least R-13 and R-38 is the figure for ceilings. Ceilings need a higher value because heat rises.

Here is a look at some popular insulation materials that you can consider should you wish to work on your house’s insulation.

Fiber has several representatives in the field of insulation. Cellulose insulation material consists of good old recycled newsprint and a fire-retardant material. It offers better insulation as compared to fiberglass and costs around the same.

Cotton is a natural, low-chemical choice as an insulation material. Batts of cotton cloth are treated with fire-retardant material and used for insulation homes.

Today, you can get fiberglass that has up to 40% recycled content in it. The fiberglass is also available in bags which takes care of the problem of flying fibers.

Mineral wool provides excellent insulation against sound, water, and is naturally fire-resistant. It is also resistant to pests. It is one of the best insulation materials out there. Mineral wool fibers are made from basalt rock. The fibers may cause problems similar to fiberglass fibers but the material can also be used as rigid-board foundation insulation.

Sheep wool is an effective and comparatively inexpensive insulation material similar to cotton. It can be used as batts or fiber.

The other major insulation type is foam; here are some foam-based insulation materials.
Cementitious insulation material is made from magnesium oxide cement that is mixed with water, air is pumped into the mixture and the mixture is pumped into cavities. This mix is fireproof and resistant to molds.

Polyurethane foam is made from polyisocyanate. It is available in two types, closed-cell and open cell. Closed cell polyurethane gives a higher R-value. Some qualities of polyurethane foam are made from agricultural products such as soybean oil and sugar. These are environment friendly options.
