Are you a Minneapolis homeowner with a front door that is at least 10 years old? If so, it's likely time to consider a replacement door.
The truth is that older front doors no longer fit as snugly as they used to. They are also likely to have lost some of their insulation properties. What does this mean for you? Bigger utility bills and an uncomfortably drafty home.
This is why it's important to research door energy efficiency if you're shopping for replacement doors in the Twin Cities. To help, we've created a guide that explains what makes a door energy efficient. Read on.
Not every replacement door is made up of the same components and features. Even so, here are the basics of what makes an entry door energy efficient:
Glass: A front door without glass will be more energy efficient than a front door that contains glass.That said, the glass used in today's doors is very advanced and greatly minimizes energy loss.Multiple panes, low-e coating, and insulating glass between the panes will all ensure an energy efficient door. Of course, if you want a windowless replacement door in the Twin Cities, you don't have to worry about this aspect.
Insulating Core Materials: Today's fiberglass and steel doors are typically filled with an insulating foam material called polyurethane. This prevents energy from flowing through the door itself, which keeps the inside of your home a consistent temperature.
Tight Fit & Weather Stripping: These help stop drafts in the frame of your door. This is crucial, since even a 1/8" gap between the frame and the door creates similar energy loss as drilling a 5½" hole in the center of your door. Proper weatherstripping and quality installation keeps your home insulated and your utility bills lower.
If you've already started shopping around for a replacement door in Minneapolis, you've probably heard about R-value. R-value determines how well a material resists heat flow. The higher the R-value, the better a door will retain heat in your home. The average R-value of fiberglass and steel entry doors is R-5 to R-6 (this does not factor glass in the door). Some fiberglass entry doors have R-values as great as R-15.
Insulation materials inside the door determine its R-value. The kind of insulation materials used in manufacturing the door determines R-value. For example, both polystyrene (a.k.a. Styrofoam) and polyurethane (spray foam) are used for door insulation. But polyurethane provides higher R-value because it expands after it's installed inside the door's core.
Here's food for thought: Energy moves through your door in four separate ways, but R-Value measures only one of them! Here are the four ways energy moves throw a door:
