Your home can be insulated in many different ways.

Insulation is a good investment. You will pay less for your utility bills, also. Your home can be more comfortable in the winter months. It will also feel better in the summer heat. Several kinds of insulation are available. Spray foam ceiling insulation may worth your consideration.
Spray foam insulation is one of the newer choices for your attic. It has the ability to seal your ceilings as well as insulate. Other forms of insulation cannot do that for you. This can keep out pests like rodents and insects. The sealing property can increase the air quality in your home. There will not be as many outside pollutants entering your house. This can be a factor for people with respiratory ailments.

You will get very good insulation from foam. It offers a lot of thermal resistance for your money. Insulation is rated in thermal resistance. It is also called R-factor. The higher the r-factor, the better your home is insulated. R30 is usually recommended as minimum attic insulation. This may depend on the climate where you live. An insulation contractor can give you more information.

Spray foam can also increase the structural integrity of your ceilings. Most attic insulation merely lies in the spaces between your ceiling joists. Foam is blown in and expands. It will stick to the ceiling joists. This can increase ceiling stability. Other kinds of insulation cannot make that claim.

You can also use spray foam insulation to insulate your crawlspace. In most cases, your crawlspace is not insulated. It is allowed to help vent your roof. However, this can expose your heat and air ducts to extreme temperature. Your attic can be considerably hotter than the rest of your house. Your air conditioner will have to work harder as a result. It will also be harder on your furnace in the winter.

If you have adequate room ventilation, you can insulate the rafters under your roof. This can be sprayed from inside. Foam will stick to the area between the rafters. You can insulate them with fiberglass building insulation. However, it will not seal the way that foam will.

Spray foam insulation may cost a little more to install. However, you will save more money, over time. It insulates and seals better than most others. You can qualify for certain energy credits also.

Summary:

Spray foam ceiling insulation will be a good investment. Your house will be well sealed and insulates. It will feel more comfortable in winter and summer. Your cooling and heating bills will be less, also.
