Need Replacement Doors In Minneapolis? Read This Door Energy Efficiency Guide First

Replacement Doors Minneapolis

Posted on August 24, 2018

Your Front Door May Be A Small Aspect Of Your Home…But It Plays A BIG Role In Your Home's Energy Efficiency & Comfort.

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.

Elements Of An Energy Efficient Entry Door

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:

Energy Efficient Doors

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.

R-Value: What You Need To Know

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.

Other Energy Factors To Consider

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:

  1. Conduction: This is a material's ability to conduct heat. Conduction happens when microscopic particles collide and produce kinetic and potential energy. Conduction occurs when heat moves through the solid aspects of a door, like the jambs, rails, slab, and sill. Conduction is what R-value measures.
  2. Air Infiltration: This measures the transfer of energy in potential gaps between the parts of a door (the frame and slab, for example). Weatherstripping and tight installation will stop air infiltration.
  3. Radiation: Radiation is created by the thermal motion of charged particles in an object. Low-wavelength, invisible, infrared radiation can carry heat straight from from warm objects to cool objects. Radiation does not require contact between the heat source and the object being heated. It's why you can feel the heat from your stove from three feet away and the sun from 93 million miles away.
  4. Convection: This is the process of cold air sinking and warm air rising. Insulation in a door helps keep energy flow more stable to help prevent heat loss.
