Insulation is a Year Round Investment

As summer heat peaks, many homeowners are grateful for the cool comfort provided by their air conditioning. However, running the A/C non-stop can lead to high energy bills, especially if your home isn’t properly insulated.

While most people associate insulation with winter, it’s just as beneficial during the summer. Remember from school science class how heat rises? This means that your top floor and attic are naturally warmer than the lower floors. Without insulation, your attic can become much hotter than the outdoor temperature. If you touch your ceiling and it feels warm, imagine how hot it is above it.

Insufficient insulation forces your air conditioning units to work harder to maintain a comfortable temperature. Whether you have central air or window units, they are straining to cool your home, which spikes your energy costs.

Improving your home’s insulation can make a significant difference. The attic is a prime area for insulation upgrades due to its large space and extreme temperature variations. Although it’s often overlooked because we don’t spend much time there, adding insulation in the attic can be a cost-effective home improvement. Options include blowing loose fiberglass under the floor or laying batts between the floor joists. The best choice depends on your home’s size, attic clearance, and usage. A well-insulated attic not only reduces energy costs but also increases your home’s resale value.

In addition to the attic, sealing gaps around windows and doors helps keep cool air inside. Check your door sweeps and replace them if necessary, and use caulk or sealing tape on windows. This practice will benefit you now and in the winter when you’re trying to retain warm air.

For those with window A/C units, insulating around them is crucial. Use flexible foam to create a good seal at the top and bottom of the unit. Ensure the side curtains are tight-fitting and securely anchored. Without proper insulation, your window A/C unit isn’t operating at full efficiency since much of the cool air escapes outside. Taking these extra steps ensures your A/C works effectively.

Another area to consider is your home’s walls. If your house is older, it may not have adequate wall insulation. Adding insulation to your walls can prevent heat transfer, keeping your home cooler in the summer and warmer in the winter. There are several methods for insulating walls, such as injecting foam insulation or using blown-in cellulose. These options can be a bit more invasive but are worth the investment for the long-term comfort and efficiency of your home.

Additionally, consider insulating your floors, especially if you have a basement or crawl space. Insulating these areas can reduce heat loss and prevent moisture buildup, which can lead to mold and mildew issues. Foam board or rigid foam insulation works well for this purpose and can be installed relatively easily.

Don’t forget about your ductwork. If your home has central air conditioning, ensuring your ducts are well-insulated can prevent energy loss as the cool air travels from the unit to various parts of your home. Leaky or uninsulated ducts can lose up to 30% of the cooling energy, making your system work harder and increasing your energy bills. Sealing and insulating your ducts can improve efficiency and enhance overall comfort.

Lastly, consider the benefits of radiant barriers. These are reflective materials installed in attics to reduce heat gain during the summer. Radiant barriers work by reflecting radiant heat away from your home, helping to keep indoor temperatures down. This is particularly beneficial in hot climates where the sun’s intensity can significantly impact indoor comfort.

Investing in insulation is a smart move for homeowners looking to improve comfort and reduce energy bills year-round. By addressing key areas like the attic, windows, doors, walls, floors, and ductwork, you can create a more energy-efficient home that stays cool in the summer and warm in the winter. The initial investment in insulation will pay off through lower energy costs and increased home value.

What To Look For When Shopping For an Energy Efficient Entry Door

Many people don’t give much thought to their front door, which is surprising considering that it both sets the tone for a home and is a huge contributor to its overall comfort level.

If you’re in the market for a new entry door, there are a lot of factors to take into consideration beyond just color and style. I’m a huge fan of energy efficiency and all too often, I see homeowners losing massive amounts of hot and cold air through ill-fitting old doors with little insulation. Luckily, consumers have some great resources in their corner which can make choosing a new door a real breeze.

Energy performance is often measured by ENERGY STAR®, the symbol created by the Environmental Protection Agency to measure energy efficiency here in the United States. Another label you may see is from the National Fenestration Rating Council (NFRC), which independently tests and certifies products to give consumers more transparency around efficiency. Both of these rating systems rely on several vital performance contributors that you’ll want to pay attention to. Let’s take a closer look.

1. U-Factor measures how well the product keeps heat from escaping a room, which is vital to our cold winters. It’s important to look for a low number here, which identifies a high performing product. Ratings generally range from 0.20-1.20.

2. Solar Heat Gain Coefficient or (SHGC) measures the opposite. This rating helps a homeowner to know how well a product can resist heat gain, which is crucial in the summer. Again, the lower the number, the better - with 0-1 being the range for this measurement.

3. Air Leakage is exactly what it sounds like and if you’ve ever stood next to a door with worn weatherstripping, you’ll know how important it is. Look for a product with a low air leakage rating, generally expressed in units of cubic feet per minute per square foot of the frame area (cfm/ft2). This measure is also highly dependent on the installation of the product, so having a knowledgeable installer is critical.

4. Sunlight is another important factor which is measured through Visible Transmittance or VT. VT is a fraction of the visible spectrum of sunlight that is transmitted through the glazing of a door and weighted by the sensitivity of the human eye. This is measured in nanometers on a scale of 0 to 1. The lower the number, the less the light is transmitted.

5. Finally, Light-to-Solar Gain (LSG) is the ratio of SHGC to VT and helps homeowners understand how light is transmitted relative to heat gain. The higher the number, the more light that is transmitted without adding heat. This number isn’t always provided but can be useful depending on the positioning of your door and its exposure to the sun.

Don’t forget, exterior doors should look great, but their key function is to provide a barrier against the elements. When you’re shopping for one, keep these factors in the forefront of your mind and you’ll be taking all the steps necessary to maintain your family’s comfort for years to come.
