If you are told that your attic along with the roof are two of the weakest places in your thermal insulation system it is possible that many may not believe. According to statistics poor (or absent) attic insulation will account for up to 15 % of the total energy loss in your house. Insulating an attic which is generally unheated is vital in the home energy saving process.
What is really the attic in your building?
Attic is defined as the space enclosed by the building wall and is located directly under the roof. As this is an area generally not occupied continuously by anybody (except in special designs and home modifications) it is unheated. Some components of utilities such as water heaters, hot water storages, air conditioning and heating air ducts and also goods storages may be located here depending on the volume of space available. Generally the roof and the floor are insulated though more often than not inadequately.
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.
Areas of heat loss in an attic
Some major points of heat loss have been identified by researchers. For example;
** Attic floor
** Air vents
** Attic access
** Poorly erected hot/cold air distribution ducts and,
** Poor insulation in hot water tanks and plumbing
The silver lining in the whole issue is that of all insulations of an old or new building attic insulation is the easiest to tackle. And in most cases can be carried out by semiskilled amateurs as a DIY project perhaps during a weekend!

Professional spray foam insulation contractors typically insulate an attic by applying a thick layer of spray foam between the rafters. Two types of foam are used: open-cell and closed-cell. Opinions vary as to which type is best in an attic installation, but closed-cell spray foam is used more frequently.
Provides all the benefits of spray foam, with the additional benefit of maintaining attic ventilation. The potential for roof sheathing moisture damage is eliminated. The rigid foam is faced with a radiant barrier that reflects heat for additional energy savings -another advantage over spray foam.
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.
Selection of appropriate Attic Insulation Minneapolis 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.
