By the end, you’ll have the knowledge to select the perfect garage door that checks all your boxes for functionality, efficiency, design and budget. Let’s get started!

What Makes a Garage Door Energy Efficient?

When many people think of energy efficiency, they often overlook the garage door. However, this large barrier between your home and the outside elements plays an important role in regulating temperature, noise, weather and more.

The more energy efficient your garage door, the better protected your home. Energy efficient doors have higher R-values, thicker insulation, improved weather seals, sturdier construction and enhanced opening systems.

All of these features work together to prevent the transfer of heat and cold, block outside noise, withstand impact and wear, and operate smoothly for years of reliable access. They also reduce energy costs associated with heating and cooling loss.

Over the 10 to 30 year lifespan of a quality garage door, an energy efficient model can save you hundreds of dollars in utility bills.

What Makes a Garage Door Energy Efficient

Determining the Correct Size

One of the first considerations when selecting a new garage door is proper sizing. Even if you choose the most energy efficient model, an improperly sized door can leave problematic gaps, not seal correctly and essentially render those efficiency features useless.

Here are the key measurements your garage door dealer will need:

  • Opening Width – The distance between the side garage door jambs
  • Opening Height – The floor to ceiling distance
  • Sectional Panel Height – The actual section height of the door

The opening width and height allow the dealer to order the appropriately sized door. The sectional panel height indicates how many panels your door will need.

Getting accurate measurements is crucial, so don’t skip this step! Most dealers will come take measurements themselves to ensure precision.

5 Efficient Materials for Garage Doors

Once you know the proper size, it’s time to explore material options. Garage doors today come in a range of materials, each with their own insulating properties, durability, maintenance needs and cost considerations.

1. Steel

  • Benefits – Exceptionally durable, impact resistant, affordable
  • Efficiency – Foamed in place insulation increases efficiency
  • Considerations – Can dent, rust without preventative coatings

Steel continues to be the most popular choice for garage doors. Available steel gauge thicknesses range from 20 to 28 gauge, with lower numbers indicating thicker steel construction. Many energy efficient steel doors use a foamed in place polyurethane insulation core.

2. Wood

  • Benefits – Aesthetically pleasing, good insulator, customizable
  • Efficiency – Depends on wood type, can be coated with insulation
  • Considerations – Expensive, high maintenance, less durable

For a classic appearance, wood remains a top contender, although it is one of the more expensive options. Wood provides effective insulation, but lower R-values than steel and foam doors. Special coatings and cladding can enhance efficiency. However, wood requires extensive, regular maintenance to prevent cracking and deterioration.

3. Fiberglass

  • Benefits – Durable, dent/rust proof, mimics wood grain look
  • Efficiency – Foamed in place insulation increases efficiency
  • Considerations – Heavy, expensive, prone to cracking

Offering a unique composite construction, fiberglass doors feature a steel infrastructure reinforced by glass fibers. Like steel doors, efficient fiberglass doors have an inner foam insulation core. Fiberglass holds up well to weathering but the material itself is less thermally efficient than foam and wood doors.

4. Vinyl

  • Benefits – Affordable, good insulator, low maintenance
  • Efficiency – PVC is not the best insulator compared to other materials
  • Considerations – Less durable than most materials

Vinyl garage doors offer an inexpensive, low maintenance option. While vinyl provides decent insulation, it performs the poorest out of all door materials. Vinyl dents easily and the plastic material tends to crack over time. Hail storms and errant balls can do a number on vinyl.

5. Composite

  • Benefits – Blend of materials, customizable finishes
  • Efficiency – Varies based on exact composite
  • Considerations – Generally more expensive

Composite garage doors offer flexibility in design by blending materials like aluminum, steel, vinyl and wood fibers. Efficiency depends on the exact makeup, but composites offer the potential for improved insulation capabilities. However, costs are typically higher.

Now that you know the properties behind each material, it’s easier to zone in on the right one for your climate and home architecture.

4 Special Features for Garage Doors

Beyond efficiency and durability, several other convenient or aesthetic features exist to deck out your garage door exactly how you’d like it:

Windows – Full-view aluminum framed windows add an elegant focal point and ambient lighting into the garage interior. Come in a range of sizes, patterns and designs.

Insulated Glass – For the look of windows but with efficiency perks, insulated glass utilizes tempered, double pane glass for improved insulation over standard windows.

Decorative Hardware – Swap out standard galvanized handles, hinges and fixtures for decorative black powder coated or antique iron hardware for visual flair.

Custom Wood Tones – Steel garage doors can mimic luxury wood looks through synthetic wood grain finishes in different stains from natural oak to darker exotic woods.

4 Special Features for Garage Doors

Average Costs for New Garage Doors

Costs vary based on size, materials, insulation, design intricacy and special upgrades. Here are average installed prices:

  • Steel door prices range from $600 – $1,500
  • Wood door prices range from $800 – $5,000
  • Fiberglass and composite doors range from $800 – $2,500
  • Insulated doors average $1,000 to $3,500+

When weighing costs, don’t forget the long run savings from enhanced energy efficiency. Those making especially green upgrades may qualify for rebates and tax incentives as well which offset initial pricing.

Getting multiple dealer quotes helps guarantee you receive reasonable pricing for the options and quality you want.
