Insulation for Virginia Home
The most important place to be insulated in any Virginia home is the attic area. While insulating the attic the most important thing to be kept in mind is the material that you are using for insulation as well as the R-Value of that material.
If the temperature range in your area is very extreme, you will need to have insulation with higher R-Value. There are various kinds of insulation available for the attic in Virginia. Virginia also comes under the climate of zone 4 and so the recommended insulation for the attic in Virginia homes is R38 to R60 type.
Before you carry out the insulation process for your finished attic you must take help of the professionals to check the old insulation that is already present. If the older insulation is vermiculite type than it contains mostly asbestos and that is to be removed before new insulation is added. Asbestos containing insulation has a very higher risk of health and so only those who are expert in dealing with it must use the vermiculite insulation.
They check the amount of insulation already present and its condition and on the basis of that they decide the amount of insulation to be added more. For easy bondage between the older and newer insulation they try to use the same insulation that is already present if possible. If you are using the fiber glass insulation, than they must be applied perpendicular to the joists. As a result of this the older insulation is compressed besides the newer insulation.
The attic must be insulated until you achieve the desired amount of R-Value of that insulation or else the insulation will be of no benefit to you. Some times it even takes the whole day for insulating the attic. For easy access to all the area of the attic you must lay down some temporary flooring. Thus it helps to have an access to all the areas where it is very hard to reach.
If the attic is insulated properly in Virginia home than your family will be gifted with a comfortable home and you would enjoy saving on your electric bills.
Not just insulating the attic only serves you a fully comfortable house. There are various crawl spaces as well as the air infiltrations that need to be sealed timely and effectively. The problems of moisture in the house must also be given a head during insulation. Crawl space insulation also depends on the ventilations in your house. Traditionally it was believed that the crawl spaces must have proper ventilation so that the problems of moisture are all removed.
However these days the expert contractors suggest building an unventilated crawl space but it must have proper exterior drainage techniques and control over the moisture. The main reason behind such initiative was that if there are ventilations in crawl space than in winter it would be very difficult to keep it warm. The other reason was that the moist air from outside used to sweep inside and made it difficult to dehumidify the crawl spaces in summer.
It is a very good idea to insulate the trusses of the floor with the help of foam based insulation. Then after, it is recommended to fill the space between insulation and the sub floor with loose fill insulation.
Insulation also acts as a very effective sound absorber. When you have completely insulated your Virginia house it may stop the sound transferring between one room to other inside the house and also reduces the noise of the outside disturbance coming inside the house.
