It’s the goal of every property owner to increase energy efficiency in their homes and offices all year round including wintertime and summertime. Enhancing your property’s attic insulation is a great way of increasing overall efficiency. As a matter of fact, almost 85% of heat loss in a property passes through the attic.
According to the U.S. Department of Energy, increasing attic insulation can lower your heating costs by between 10 and 50% depending on your current level of insulation. However, you should also consider other variables such as roof condition, exposed ductwork in the attic, and venting. These variables can greatly affect the overall cooling and heating system performance. Below are the top ways to make your attic as efficient as possible.
Install Sufficient Insulation
Insulation is one of the best ways to boost attic efficiency. According to statistics, most homes built before the 1970s have insufficient attic insulation. You can engage the services of a professional to carry out tests to assess the insulation of your home.
Insulation is measured by ‘R-value’ and changes depending on the climate; the higher the value, the better the insulation. Environmental Protection Agency (EPA) have simple equations to help property owners establish how much insulation they require based on the type of insulation (sprayed fiberglass or solid batts), climate, and depth of current insulation. You can try this and find out areas that need additional insulation in your property.
Use Air Sealing
This is an important element in enhancing your attic energy efficiency. Air sealing not only helps to increase efficiency, but also boosts indoor air quality. Improperly sealed attic allows dust, dirt, and other allergens into your indoor space thus lowering the quality of air.
Check for gaps around ducts in the attic, spaces around lighting fixtures, and cracks in the ceiling. Caulking around the air leakage will be the best solution for this.
Ensure Vents are Working Optimally
Proper ventilation is crucial to prevent mold and mildew into your indoor space while keeping the air fresh. The air should also be free from allergens and microbes which can cause asthma, allergies, and other respiratory diseases. Proper ventilation is of paramount importance for an efficient attic. However, you must ensure that your property is properly insulated and air sealed.
Invest in Attic Fans
Attic fans play a crucial role in keeping attics cool during summertime. They help to draw hot air from the attic while bringing cooler air inside.
For the fans to work effectively, the attic should be well insulated. This is important because air leaks between your living space and the attic will mean that the fans will actually draw the conditioned air out of your property. This will have a ripple effect of lowering the efficiency of your systems.
To add to the above, ensure you insulate attic ductwork and add a reflective roof. Attic efficiency improvement project can be costly, but it’s worth every dollar you invest in it. It will pay big in the long run through lower energy bills.
