MORE INFO

If you want to keep your house cool during the summer and warm during the winter, you need to install the best attic insulation. Contrary to popular belief, insulation is not just for keeping your home warm. It can also be used as a shield against radiation and summer heat. Insulation is any material that slows down the transfer of heat from one area to another.

The most obvious example of insulation at work in everyday life is in a cooler or thermos bottle. The insulation material, usually made of foam, keeps hot things hot and cold things cold. In other words, it slows down the rate at which outside heat enters the inside vacuum. Your attic, if properly insulated, also acts as a vacuum. If you do a proper insulation installation, your attic will be completely enclosed.

This is the equivalent of shutting your thermos bottle air tight. With this setup, heat and radiation from the outside will penetrate your home at a reduced rate during the summer, thus keeping your house cool. During the winter, the outside cold air will take longer to get into your home, which keeps your house warm.

This blown insulation is really designed for the Do It Yourself types who want to save thousands of dollars on hiring professional attic insulation installers. Cocoon insulation is made of cellulose, which is a great green product.

Cellulose is great at filling areas that are hard to reach and to insulate with our methods of insulation.

If you install the insulation yourself using a rent insulation blowing machine, you can save yourself hundreds of dollars.

You can even spread this by hand and save yourself even more money if you want. You want to fill up your attic with this insulation at about 4 inches of thickness. Since one bag only covers about 40 square feet at about 4 inches of thickness, we suggest you get about 20 of these bags to safely cover a normal sized attic. Cellulose insulation is one of the most popular and efficient methods of attic insulation. It has a relatively high R value (3.7) and for the most part higher than that of fiberglass. Higher R values correspond to higher insulation power. In our opinion, it is the best bang for the buck.

Foam It Green 602 Closed Cell Spray Foam Insulation Kit

If you are looking for a spray foam insulation, the Foam It Spray Foam Insulation Kit is the best attic insulation kit for you. First and foremost, this kit provides about 602 square feet (at 1 inch thickness) of cured foam. It also comes with an extremely high R- value of 7. Remember, the higher the R-Value, the more the material insulates heat.

This spray foam is a closed cell foam, which means it is very hard and incredible at insulation because of its high R- value per inch. It is sprayed directly on the underside of the roof instead of on the attic floor. We would highly recommend using a spray foam system if you have an HVAC system in the attic. This is because you probably want your air conditioner or furnace to be protected from the outside heat.

If you use a traditional blow in insulation, you are only insulating the attic floor and exposing your HVAC system to the outside heat or cold. Since you apply spray foam on the inside of your roof, you also form a protective layer of insulation around your HVAC system. We like the Foam It system because it is a completely kit with everything you need inside, including spray canisters. Unlike other products you buy where you have to buy all of these hidden tools for installation, with the Foam It system, you get everything.

For example, with blown insulation, you need to buy or rent an insulation blowing machine. The machine itself is which is not included. The Foam It kit passes all of the most stringent safety tests and is guaranteed to be non-defective. The foam is directly sprayed on your attic roof inner walls. It should be dry to touch in 2 minutes. You should always monitor whether it turns into a light green color, which is a sign that it is working properly. Stop immediately if it changes colors.

RadiantGUARD Ultima-FOIL Attic Foil Insulation

If you want the best attic insulation for making your attic cooler and saving money on air conditioning, you should look into the RadiantGUARD Radiant Barrier.

Radiant Guard Ultima Foil is double sided and made of 99.9% pure reinforced aluminum. It blocks nearly 97% of radiant heat during the summer and winter. And this foil barrier isn’t like the aluminium foil found in everyday households.

More Info on the Best Attic Insulation

While there are many types of attic insulation, there are only three main types that people normally install these days. These are foil insulation, blown insulation, and sprayed insulation. The first type of insulation, foil, blocks radiant heat energy. When the sun shines on your roof, it can reach temperatures of over 150 F without proper foil insulation. Foil has radiant barrier properties that reduce the amount of the sun’s heat that gets transmitted below. In turns, it reflects most of the heat back up. Blown insulation is another type of insulation that involves blowing a filling material using a hose throughout your attic.

This material is usually fiberglass or cellulose and comes in the small chunks. These chunks stack up on top of each other and form a tight gapless layer. Blown insulation is great at filling up holes and gaps in your attic. Lastly, there is sprayed insulation, which involves spraying a layer of foam around your attic that hardens. Spray foam comes in two forms: open cell or closed cell. The primary advantage of spray foam is moving the building envelope from the attic floor to the roofline.

Basically, if you spray foam in the roofline, you can bring your HVAC system and ducts inside the building envelope. This means that you don’t even have to redesign your entire system or house. If you don’t have an HVAC system of ducts in the attic, don’t worry about spray foam. Just use blown insulation. It is the best attic insulation if you are concerned about price.
