What Are the Overall Top Energy-Efficient Doors You Can Buy?

The best energy-efficient doors you can buy right now are the Emerson Therma-Tru fiberglass and Masonite Steel Primed doors. These doors have a polyurethane foam core – one of the most energy-efficient materials on the market – placed in the middle.

Best Fiberglass Door: Emerson Therma-Tru Benchmark Fiberglass Door

This energy-efficient door has an R-value four times more than wood doors because of its solid polyurethane foam core.

Therefore, this door effectively prevents heat from escaping outside and cold from entering your home. Moreover, the glass is triple-paned and low-emissivity (Low-E) to control heat flow into your house. As a result, you can significantly reduce your energy bill.


  • Various finishes – you can choose from multiple stains and paint colors that suit your house. For example, paint shades include mustard, sage, forest green, real red, and black, while the stains range from light oak to walnut and mahogany. With all these different finishes, you can make your home entry beautiful and welcoming.
  • Easy installation – this energy-efficient door is pre-hung, making it easier for you to install it yourself. Pre-hung means that the door comes with the attached hinges and all the materials you need to hang it up. However, if you are not comfortable doing the fixing yourself, you can ask for professional installation service or get your carpenter to do it.
  • Durability the Benchmark is less prone to getting dents, rust, and rot, enabling it to stay at its acme for years. This longevity is because it has a polyurethane core, which makes it resistant to damage. 
  • Lifetime limited warranty – you are assured of a replacement, a repair, or a refund if the door gets defects, such as cracks, peelings, and blisters. These damages should, however, not be a result of your failure to comply with the company’s installation, finishing, and maintenance—otherwise, the warranty may become void.


  • Restricted purchase – you can only buy this product from Lowe’s. So the store’s unavailability may cause shipping delays. Besides, if you prefer to shop locally, you may be lured out of buying it.

The Masonite No Glass Steel Door is remarkably insulated with a polyurethane foam core placed inside the door to help you save energy. Moreover, the lack of glass, which tends to be less effective in preventing heat transfers if it is not double or triple-paned, chemically treated, and weatherstripped, makes the door more energy-efficient.

  • Secure protection this product is made from high-definition steel for ultimate security. In addition, the deadbolt lock plate applied to the jamb provides extra security, making your home hard to break in.

  • Restrictive warranty if you trim the door for a better fitting, in case it’s necessary, you can end up voiding the warranty. Yet, at times doing so is unavoidable because the length of the door may be longer than the available space. To avoid resizing the door, carefully measure your door frame to get the correct measurements before buying this product.

Factors To Consider When Buying an Energy-Efficient Door

Before you decide to replace your old one with an energy-efficient door, some things you should consider first include:

  • The energy efficiency of your entire house – your windows should be insulated and weatherstripped to prevent cold air from entering and heat from escaping. It would help if you also protected the walls with wraps to avoid heat loss through conduction or convection, and you should cover any holes in the walls. You may even take it a step further and install energy-saving lights.
  • The area you live in – you may prefer a particular type of energy-efficient door, but it may not suit the weather in your location. For instance, you may want a sliding door yet stay in a cold area, making energy-saving difficult because these doors do not offer a tighter seal like swinging ones. Moreover, fiberglass insulated doors are the best for keeping homes insulated in all conditions.
  • Whether a door repair cannot do the trick, repairing your existing door to cover the holes and cracks and fix the weatherstripping may do the trick. Therefore, investing in a pricey, energy-efficient door is not always necessary. However, if you notice that your old door is beyond repair, you should buy a new energy-efficient door to help you cut back on utility costs.

Key Takeaways

Even though there’s no shortage of different materials for energy-efficient doors, fiberglass provides the best insulation for your home. However, a steel door does the best job if you’re looking for an energy-saving and highly secure option.

When choosing an energy-efficient door, keep all your preferences in mind to make a well-informed decision.
