Does Your Attic Lack Insulation

Insulation plays a major role in your homeÕs levels of functionality and comfort. Proper insulation is the only way to attain stable air temperatures while external temperatures shift. Without the proper insulation, your home can feel consistently too hot or too cold, and will be forced to use much more energy while heating or cooling the property.

One area of the home that is commonly lacking insulation is the attic space. A non-insulated attic can actually account for nearly half of your homeÕs heat loss. Canadian attic spaces need adequate insulation.

Loose-fill insulation, insulation batts and spray foam insulation are all common attic insulation choices. Radiant barriers and rigid foam boards can also be used in speciality situations. Have a professional inspect your attic and install any new insulation to make sure your getting the most from the project

Recommended R-Values
R-value is defined, as the amount of airflow resistance a room should have in order to attain consistent temperatures. Different insulation types can offer different R-value per inch of thickness. Canadian homes should carry relatively high R-values due to cold air temperatures, with the attic spaces leading the pack. Some recommended R-values for different areas in the home are:
* Floors- R25 or higher
* Interior Walls Ð R15 or higher
* Exterior Walls _R25 or higher
* Attics Ð R40 or higher
The exact requirements can vary based on your properties location, local weather patterns, wind levels and more. An adequate R-value is a key to any successful attic insulation.

Insulation R-Values
Attics require rather high property R-values to make sure they remain as a benefit to your home and to your finances. Selecting the right insulation type of combination is key to getting the most from the attic insulation project. These are 3 common types of insulation and their relative R-values:
* Loose Fill, Blown In Ð Loose fill insulation is made of either cellulose, fibreglass or stone wool and can offer an R-value of 2.2-4.2 per inch of thickness. The insulation is installed efficiently by breaking down large pads on insulation in a machine and blowing them into the attic space through a large hose up to the desired depth. Loose fill insulation covers the base of your attic and the space will need about 13 inches of the material to reach desires R-values.
* Batt & Blanket Ð Insulation batts are available in a number of designated thicknesses and made of cotton, stone wool or fibreglass. The batts are cut to size and placed snugly between the joists on the attic ceiling. Insulated batts offer an R-value of 2.9-4.2 per inch of thickness meaning you would need about 12 inches thick batts to achieve an R-value of R40. Thinner batts can also be used in cooperation with other insulators to achieve the desired level of airflow resistance.
* Spray Foam Ð Spray foam is the most powerful style of insulation. The material can offer n R-value above 6 per inch and can create watertight seals in your attic space. Spray foam can be effectively used with batts or loose fill to seal hard to reach crevasses. When used as the sole insulator, spray foam requires effective attic ventilation to not trap unwanted moisture in the air.

Benefits Of Attic Insulation
Attic insulation can offer several individual benefits and advantages. Two major advantages to a well-insulated attic space are:
* Moisture Protection Ð Attics can take on moisture from rising air and roof leaks. The moisture can damage building materials grow mold. Insulation helps keep moisture out and can help identify leaks before they worsen.
* Energy Savings – Insulation keeps heat or cool air in. This means you will need less energy to heat or cool your home in the respective seasons. A well-insulated attic can lower your energy cost by upwards of 15%, allowing the projects to pay for themselves in the months and years to come.
