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.

Simple Sealing Solutions to Retain Lost Heat in the Home

Old, drafty windows can be a killer this time of year - both in terms of comfort and cost. Cranking up the thermostat to combat escaping heat can often double or even triple your energy bills, plus it makes your heat and cooling systems go into overdrive which can shorten their lifespan.

While I am a huge fan of the latest and greatest energy efficient windows on the market, I understand that sometimes replacing that old glass isn’t in the budget. Keeping this in mind, I wanted to give you a few tips to help you retain some of the heat you’re losing from those old windows.

First, it’s important to remember that windows are one of the biggest sources of air leaks, which is a big deal in two of our four seasons. In the cold weather they let the heat escape, and in the warm weather they let it in, making your climate control systems work much harder than they have to. While the simple solutions I've outlined below will help you retain some comfort, window replacement will be your best bet long term if you’re tripling your energy bill during certain months of the year. So let’s get to the tips:

1. Put up curtains. Believe it or not, hanging heavy fabric drapes can help you retain up to 25% of the heat in your home. This is especially true with large glass doors that aren’t being used in the winter months. The fabric acts as a barrier and while it won’t stop the air from getting out, it will slow the leakage. Plus, they can be very helpful in the summer, especially if your house gets a lot of direct sunlight.

2. Seal up gaps. Wooden window frames get warped with age and can lead to serious air leakage. For cracks that are smaller than a quarter of an inch, a silicone caulk will work to plug up areas where air can flow through. For larger gaps and places that need to still open and close, weatherstripping is an excellent solution. It comes in foam, felt, vinyl and other materials and is both cost-effective and easy to install.

3. Add a layer. Single pane windows in homes that were built more than 50 years ago simply can’t stand up to our cold winters. If you feel air coming right through the panes and the glass rattles with the wind, beef them up with some heat shrink film. This product can be found at any home supply store and can be cut to fit just about any pane. Using heat from a hairdryer, the plastic adheres to the glass, giving you a little bit of extra protection against the cold.

4. Close up the attic. While not a window, people with an attic hatch are likely losing a ton of warm air through its frame. We all know that hot air rises, so seal up that hatch with heavy duty plastic, or build yourself an insulated box to fit over the entryway if you still need access to storage.

5. Don’t forget the doors. We don’t often open the windows in the winter, but doors are a different story. They let lots of air escape, but they can’t be sealed completely because we need to use them. I always suggest inspecting your door sweep to ensure it’s not damaged, and replace it if the bristles have come loose. A door snake or seal can also come in handy, which can be purchased at any big box store or even made at home with an old pair of tights and some rice, beans, newspaper or another filling.

Don’t Let Your Home Get Drafty This Winter

If your house has old doors, winter can be a drafty time of year. Luckily, there is an easy, do-it-yourself fix to help you keep the cold air out and the warm air in where it belongs. Here is my guide to sealing your doors before the real cold sets in.

Examine your current weatherstripping for any rips, bends or wear and tear. In older doors, the seals usually deteriorate before the doors themselves, which will allow air to pass through. If you can feel a draft coming from the edges around a closed door, it’s time to give them a little facelift. However, if the door is damaged, sagging, or rattling, it might be time for a new one entirely.

Measure the top and sides of your door jambs with precision; you want the fit to be snug and airtight. I always say, measure twice and buy once! Once you measure the doors, you’ll find the materials that you need either at the local hardware store or online on any home improvement retail site. In addition to weather stripping, you might also need a sweep, which is the strip along the bottom of the door that looks like a tiny broom and keeps the gap between the door and the floor sealed. If yours is damaged or has broken off in parts, now is a good time to replace it. Luckily, basic individual weatherstrips and sweeps can cost as little as $10 each, which is a lot less than investing in a new door.

Just like painting, when you start weatherproofing you’ll need to begin on a clean surface. Scrape any old debris so the gap is free and clear. You want to make sure your gap is in good shape to lay the strips evenly and you need to have enough room for the strips to grip properly.

Finally, you can install your new weatherstripping. Cut it to size before you put it in the groove and ensure that you don’t stretch the material to fit – it will return to its original size and leave you short. Secure it firmly into the groove and open and close the door to look for any protrusions or gaps.

Weatherstripping is a quick, inexpensive fix that will help you stay warmer in the winter and give your heating bill a noticeable break. But just like any home improvement tasks, if you’re not comfortable using basic tools and equipment, you might want to leave the job to a professional. Either way, keep your family warm this winter and take some time for yourself to enjoy the holiday season.
