About Attic Insulation

Attic Insulation Reduces Electricity Bills

Attic insulation is an effective way to reduce electricity bills. It also increases the value of your house. The following tips will help you perform proper insulation in the attic of your house.

1. Selection of appropriate attic insulation type and its R-value is important. Therefore, enough information should be gathered about the building design, its climate and your budget. The insulation should be at least 9.5 to 12 inches within an R-value of R-30 or R-38 respectively.

2. The attic insulation should not only meet your requirements but it should also be in your budget range. Most commonly used insulation types are fiberglass batt, cellulose, and spray foam insulation.

3. Fiberglass batt insulation uses long insulation stripes and is very easy to install. You can give it any color.

4. Cellulose attic insulation can be blown inside covering and it provides good coverage for even smallest spaces. Also, it is available in the form of Insulation bags. One can apply it with the help of insulation blower.

5. Spray foam attic insulation works by expanding and stretching. It covers small gaps, openings, holes and cracks effectively. Specialized tools are required to apply spray foam insulation.

6. Increasing insulation from 3 to 12 inches can save up to 20 percent of the energy bills. Also, it is advisable to use high density insulation for exterior walls.

7. Maximum air flow can be ensured by installing attic vents along with the entire ceiling cavity. If there is insulation underneath the roof then do not ventilate your attic. The best option is to consult a professional.

8. Place insulation nearby light fixtures as it is the main source of heat loss. It must be applied 4 to 5 inches away from recessed lighting fixtures. The exhaust fans, pipes, boundaries, lighting fixtures, soffit vents, chimneys and framings should be sealed outside of the attic.

9. Be careful while installing insulation in your attic. Read the manuals thoroughly. Follow all precautionary measures mentioned and always wear proper gear while applying attic insulation. Hire specialized and experienced professionals if you want to apply cellulose attic or spray foam insulations.

10. If the insulation is lifted from any place then replace it immediately or fix it properly.

11. Do not block soffit vents. This ensures attic ventilation.

12. Repair all leaks before starting insulation procedure. This will help your attic insulation work effectively.

13. Properly cover the attic trap or access door.

Environmentally Friendly Roof Insulation

Everyone knows the importance of roof insulation, especially if you live in areas of extreme temperatures - hot or cold. Roof insulation can drastically reduce heating or air conditioning needs, which will save you money and help the environment by reducing the amount greenhouse gasses released, not to mention keeping you and your family more comfortable.

Upping the ante on your roofing insulation will cost you a little up front, but the amount of money you save in heating and cooling costs will quickly offset your investment. Most people are familiar with the old standby, fiberglass insulation. Typically produced in rolls or "batts," these fiberglass materials can cause itchy skin and respiratory irritation. The production process of fiberglass insulation is distinctly NOT environmentally friendly and often uses cancer-causing chemicals including formaldehyde. Fiberglass insulation is fire-resistant (a good thing) but when it does burn, it releases a number of toxic substances.

So what other roof insulation options do you have, that may be better for you, your family, and the planet? There are several available now and more new "green" insulation technologies being developed currently.

Cellulose Fiber Insulation

Recycled cellulose fiber is made from old newspaper, cardboard, and a variety of other post-consumer recycled paper products. This product is typically sprayed into the attic of the home or it may be purchased in sheets. This product has significant insulating properties, so it will save you more money than traditional fiberglass batts. In addition to being a very green roof insulation option, cellulose fiber insulation is treated with a very effective (and typically environmentally friendly) fire retardant that may actually slow the spread of fire. This product also has sound dampening qualities to cut down on outside noise and it is treated with a product that deters mice, rats, and other such vermin that like nesting in your attic. This product is slightly higher in cost but yields much higher energy savings.

Recycled Denim

Remember that favorite pair of blue jeans you had in high school? Wouldn't it be awesome to know your old stand-bys are now keeping some nice family comfortable? Denim and other cotton products are now being repurposed as roof insulation. Much like cellulose insulation products, recycled cotton insulation comes in rolls, making it much easier to do DIY installation in your attic. This product is soft and doesn't irritate skin or respiratory systems (much like your old jeans!). This product is also resistant to fire and vermin, and is an excellent sound barrier. The insulating properties of recycled denim are excellent as well. Recycled denim insulation is typically composed of about 80% recycled materials.

Soy Insulation

Roof insulation made from soy is a relatively new addition to the green roof insulation scene. This product is made from soybean oil and is applied using a spray-in technique. Once there, it expands like foam to fill in air spaces and cracks. It then hardens into a product that provides a superior level of insulating properties. This product has a very long life, typically as long as the building into which it is applied.

Wool Insulation

It's pretty expensive, but sheep's wool provides the best insulating properties available, especially in the environmentally friendly range of products. It's sustainable, environmentally friendly, and naturally resistant to fire. This product is particularly green, because the process to produce it uses the least amount of energy of all insulation options. Sheep's wool has natural moisture-resistant properties, so it is an excellent option in wetter climates. This product uses a mechanical production process and consequently, no adhesives have to be used - an added "green" bonus. It has a long life, it can be reused easily, and - when you're done with it - it can be made into compost for your garden. This product is an excellent value both for your wallet and for the planet.
