How Proper Insulation Can Save Energy
How Proper Insulation Can Save Energy
September 19, 2019
There are numerous ways you can save up on your energy bill and one of them is by having proper insulation. A well-insulated home ensures the temperature in your home is consistent while the air quality is top-notch. If air escapes as a result of improper insulation, polluted and unconditioned air can enter your home. In addition, your air conditioner will have to run for longer periods, leading to an increase in your energy bills. If you’re not completely convinced, that’s okay. The pros at DFW Thermal have some helpful information on how proper insulation can save energy, so you can be an informed and well-insulated homeowner.
The Department of Energy has some great information about what proper insulation in the home looks like and how you can save money with it:
- With proper insulation, especially in key areas such as the attic, basement, crawlspace, and floors, you can save up to 20 percent on heating and cooling costs.
- By adding insulation in these key areas, you can save up to 10 percent on total energy costs.
- The R-Value essentially determines the effectiveness of your insulation and how well it can reduce the heat flow in your home. The higher the R-Value the more insulation.
- The DOE has an R- Value requirement for each climatic region. Since we live in the Dallas-Fort Worth area with high heat and a lot of sun, our R-Value requirement is lower.
- By sealing your home with insulation, you can also control moisture and reduce the risk of mold and mildew.
Key Places to Insulate for Optimal Energy-Efficiency
- The Attic
The attic is the highest place in your home, which means air is more likely to escape from there than anywhere else in your home. Not only can poor attic insulation result in loss of energy but it can also lead to something called a “stack effect.” This happens when indoor air escapes from the top of your home, while outdoor air enters through the bottom.
If you notice a spike in energy bills, you might want to take a look at the insulation levels in your attic. You can measure the insulation in your attic by doing a visual inspection– you want to make sure the insulation covers the attic floor joists. In addition, you will also have to measure the R-Value of the current insulation that you have.
- Attic Access Door
Air tends to escape through the cracks in the door that leads to the attic as well. However, the solution for this is a pretty quick one, albeit a little pricey. You can purchase an attic stair cover, which resembles a small tent made of foil. It can be placed right behind the attic door and is often zipped and unzipped for easy accessibility.
Your air ducts keep the air moving around your home, which is why they need to be kept insulated. According to the DOE, ducts that leak heated air into unheated spaces can add hundreds of dollars to your energy bill. It can be difficult to DIY sealing ducts as they can be in hard-to-reach and even dangerous places. It is best to have a professional come in and make any repairs to your ductwork.
- Exterior Walls
Exterior walls, including walls between living spaces and garages, should be insulated to prevent excessive draftiness. Insulating exterior walls can especially be helpful in colder climates. If you’re insulating the exterior walls of an existing home, the best option might be blown-in insulation as it will provide effective insulation without disturbing areas of your home that are already set in place. However, that decision is ultimately up to you and the insulation contractor.
