subject: Utilize Spray Attic Insulation Properly - A Guide You Should Follow [print this page] With attic insulation, you can improve your own home's energy efficiency. This technique is relatively cost-effective and may save electric bill money from 20% to 40%.
Foam attic insulation is of great demand today for the reason that this is able to seal off both holes and cracks within the foam attic. Suppose that you have to spray on a layer as wide as a coat of paint, then it will expand to around 3" to 6".
The main disadvantage to spray insulation is that it's price is much higher. If you are targeting from $2 to $3 per square foot, that will not even count the attic floor. If you are fat in money, this may be a very exclusive choice for homeowners aiming to seal off having a cooler attic.
There are different types of attic insulation that you can utilize to fill out your attic. You can use loose-fill blow in insulation, spray insulation or batt insulation. Loose fill is nice for putting a layer of insulation around the floor of the attic. This depends on the required amount of r-value for your climate as to how much you will layer in there. Batt insulation is easy to setup anywhere between joists of the attic, but it is not so effective as an insulator. Spray insulation is quite of the rage the past 4 years. You may put on a layer just between the ceiling joists of that attic that will serve as a strong barrier from the sun. In fairly cool temperatures it is also capable to keep that attic.
In order to create a suitable thermal envelope, we need to check the second law of thermodynamics. This law tells that heat flows in single direction, from a warmer space to a cooler space. For instance, warm air that resides inside of a house will continue to flow to the cooler air that stands outside during winter season.
Fiberglass batt insulation protects this from happening, but there is a better technique out there for preventing loss of heat which is easy to setup and of course within your cost limit.
