You can find some of the biggest opportunities to conserve energy in your attic. Simply by adding insulation in your attic, you can maintain a favourable temperature throughout your home much better. During the summertime, proper insulation prevents the heat from sinking in, keeping your home at a comfortable temperature. During the winter months, cold air tends to penetrate the home through your soffit and into the attic. Proper attic floor insulation prevents this cold air from entering the rest of your home, pushing it back out through the roof. Attic insulation is designed to form an envelope around the home to block off any air leakage during the summer and winter months.
A relatively small investment in attic insulation can reduce your energy consumption by 20-60%. Insulation is typically installed between the heated and unheated parts of your home, such as the walls, floors and roof. Some of the most common attic insulation types include:
Blown-in or loose fill insulation is made up of fine loose fibres such as fibreglass or cellulose that are sprayed into walls or between floor and roof joists using a special equipment. Sometimes, this type of insulation can be applied through a small opening without removing drywall or other surfaces. Therefore, blown-in insulation is the ideal choice for hard-to-reach areas such as attics.
