Energy Costs Continue To Rise. It's Time To Take Action.

Attic InsulationIf your home is 10–15 years old, there’s a good chance it’s not as well insulated as it should be. Not having enough insulation results in major energy loss and, whether you realize it or not, your home is constantly leaking energy— especially out of the attic.

Since energy costs are only continuing to rise, it’s a smart idea to protect your home against these rising expenses. A well-insulated home can significantly reduce the cost of utility bills throughout the year. We want to help you save money, not throw it away. That's why, with trusted insulating systems, air sealing, moisture management and sustainable building science, Greenworks Remodeling makes it simple to enjoy Complete Energy Performance in your home.

The Importance of Adding Insulation & Sealing Air Leaks

insulate with energystarHouse leaksInsulation keeps your home warm in the winter and cool in the summer. There are several common types of insulation — fiberglass (in both batt and blown forms), cellulose, rigid foam board, and spray foam. Reflective insulation (or radiant barrier) is another insulating product which can help save energy in hot, sunny climates

When correctly installed with air sealing, each type of insulation can deliver comfort and lower energy bills during the hottest and coldest times of the year.

Insulation performance is measured by R-value — its ability to resist heat flow. Higher R-values mean more insulating power. Different R-values are recommended for walls, attics, basements and crawlspaces, depending on your area of the country. Insulation works best when air is not moving through or around it. So it is very important to seal air leaks before installing insulation to ensure that you get the best performance from the insulation.

To get the biggest savings, the easiest place to add insulation is usually in the attic. A quick way to see if you need more insulation is to look across your uncovered attic floor. If your insulation is level with or below the attic floor joists, you probably need to add more insulation. The recommended insulation level for most attics is R-38 (or about 12–15 inches, depending on the insulation type). In the coldest climates, insulating up to R-49 is recommended.

Act Today, Start Saving Tomorrow

Blown in insulationThe insulating performance of all insulation products is measured by a common standard referred to as the R-value. R-value measures resistance to heat fl ow and is usually determined by the thickness of the insulation. The higher the R-value, the greater the insulating power. By adding insulation to your attic, you can:

• Save up to 30% on your home’s heating and cooling energy costs by insulating and air sealing

• Earn a 10% tax credit up to $500

• Increase the comfort of your home, especially during the extreme heat of summer and the bitter cold of winter

• Increase your home’s resale value

Cellulose Insulation- Summary

  • Cellulous home insulation claims to be "the greenest of the green" and is now about 10% of home insulation market.
  • Cellulous has a high energy efficiency in its manufacture because it made from recycled newsprint and other paper.
  • Cellulous home insulation is unattractive to insects and rodents. Major termite and pest control companies install cellulous home insulation to help control common pests. Like fiberglass it can support mold if it stays wet.
  • Cellulous is treated with non-toxic and permanent fire retardants. It has a Class A Fire Rating from the National Fire Protection Assn. and is approved by all building codes.
  • Cellulous home insulation has outstanding sound dampening qualities. It is much better than fiberglass at reducing airflow leakage.
  • Cellulous is comparable in cost to fiberglass. Many brands are available online.
  • Cellulous insulation has about 30% more energy conservation per inch of depth than fiberglass. Limited space is a common problem in achieving consistently good home energy efficiency. Click here for more information.

Fiberglass Insulation- Summary

  • AttiCat fiberglass insulationFiberglass is the most common home insulation in America for both new construction and retrofit with about 75% of the market.
  • There is some controversy about the safety of toxic emissions (e.g. formaldehyde, HFAs & HCFCs) and the long-term health effects of breathing in very small particles from fiberglass insulation.
  • Up to 20% of the American population has some level of allergy to Formaldehyde. Long term "outgasing" of several toxic chemicals from fiberglass may not be easily recognized as a significant cause of allergy problems, particularly with small children.
  • Fiberglass emits noxious fumes when burned and is not a fire retardant.
  • Fiberglass requires a relatively high amount of energy to be produced. It takes about eight (8) times as much energy to make fiberglass as cellulous home insulation.
  • Some other insulation products are much Greener because of their higher energy efficiency in manufacture.
  • Fiberglass is competitive with Cellulous as a relatively inexpensive insulation. It can be blown in or installed with batts. Click here for more information.

Spray Foam Insulation- Summary

  • Spray Foam InsulationFoam home insulation is typically several times more expensive than fiberglass, or cellulous. Foam is about 10% of the home insulation market.
  • Foam can be the best energy conservation choice in extreme climates. It can provide a very high energy efficiency value (R Factor) in a limited space.
  • Spray foam insulation is excellent for sealing cracks, holes, seams, etc. and eliminating air leaks.
  • Foam can be sprayed as a retrofit on attic interiors and under floors. A good job requires a well-trained spray foam insulation contractor and is not recommended for DIY insulation installation.
  • Insulation contractors can use foam to retrofit walls. Insulation installation is done by pumping the foam into wall cavities through small holes.
  • A wide range of foam insulation products are available. Most are made from petroleum, but some now have a substantial percentage of soy ingredients. Long-term toxic emissions may be an issue for some products.
  • Because of the wide range in foam insulation products and training required, it is important to select a qualified insulation specialist like Greenworks Remodeling. Click here for more information.

Radiant Barrier Insulation- Summary

  • Radiaflect Radiant BarrierRadiant barrier insulation is a reflective surface that reflects heat. Often the radiant surface (aluminum foil) is backed by craft paper or bubble wrap material.
  • Properly installed in the right circumstances radiant home insulation can be effective and provide an excellent energy conservation value. Sometimes it can be a good supplement to a standard home insulation. It is most useful in tropical and humid climates.
  • Radiate home insulation does not qualify for most tax rebates or credits.
  • Sellers making exaggerated energy conservation claims have adversely affected the reputation of radiant insulation. The pricing of installed radiant home insulation is wildly variable. Greenworks Remodeling specializes in radiant insulation installation.
  • Moisture barrier issues must be carefully considered with radiant insulation. Serious damage to a structure can be caused from moisture accumulating over time in walls, ceilings, or floors. The resulting mold growth can cause significant health problems.
  • Although it is commonly done, it is not recommended to put a radiant barrier directly on top of standard attic insulation. Moisture issues can develop and dust on the reflective surface will quickly and greatly reduce the energy efficiency of the insulation.
  • Radiant home insulation products are very inexpensive and can be purchased from any large hardware store or online.
  • Done correctly, for the right energy efficiency application, radiant barrier home insulation can be an excellent energy conservation value. Click here for more information.
