Door Replacement-Keeping Bills Down

by Della Wang 19 Jul 2023 0 Comments

In a world where energy conservation has become a paramount concern, homeowners are increasingly seeking innovative ways to reduce their carbon footprint and save on soaring utility bills. Surprisingly, one often overlooked aspect of energy efficiency lies right at our doorstep – quite literally. Yes, we're talking about doors. While many may underestimate the impact of doors on home energy consumption, studies have shown that proper door selection and replacement can have a significant effect on keeping those bills down. By investing in high-quality door replacements, homeowners can transform their dwellings into energy-efficient fortresses, leading to a more comfortable living space and substantial savings on energy expenses. In this article, we will explore the various aspects of door replacement, from choosing the right materials to understanding the importance of proper installation techniques.

How to Choose Energy Efficient Doors

When it comes to door replacement, homeowners often focus on aesthetics and durability, but one crucial factor that should never be overlooked is energy efficiency. Choosing the right energy-efficient doors not only enhances the overall comfort and security of your home but also plays a significant role in keeping those utility bills down. Here are the key considerations for selecting energy-efficient doors that can make a remarkable difference in conserving energy and reducing expenses.

  1. Material Matters

 Opt for doors made from energy-efficient materials such as fiberglass, steel, or insulated wood. These materials offer superior insulation, preventing energy loss and keeping your home thermally regulated.

  1. Look for the Energy Star Label

The Energy Star certification is a reliable indicator of energy efficiency. Doors with this label have met stringent criteria for insulation, weather resistance, and overall performance, ensuring maximum energy savings.

  1. Understand U-Factor and R-Value

U-factor measures the rate of heat transfer, and a lower U-factor indicates better insulation. Similarly, R-value determines the door's resistance to heat flow, with higher values signifying greater insulation.

  1. Consider Weatherstripping and Sealing

Look for doors with weatherstripping and proper sealing mechanisms to prevent drafts and air leakage. These features not only enhance energy efficiency but also provide enhanced comfort and noise reduction.


What are Doors Made of and How Energy-efficient are They?

 In door replacement, understanding the materials used in door construction and their energy efficiency is crucial can help you keep those bills down.

  1. Wood

Wood doors offer natural beauty and excellent insulation. However, their energy efficiency depends on factors like thickness, construction, and insulation properties. Look for doors made from solid wood or those with insulating cores to enhance efficiency.

  1. Fiberglass

Fiberglass doors combine durability with impressive energy efficiency. They are resistant to warping, cracking, and expanding, providing excellent insulation. Fiberglass doors can be filled with foam insulation for enhanced thermal performance, ensuring minimal heat loss or gain.

  1. Steel

Steel doors are highly durable and offer excellent security. While they may not provide the same insulation properties as wood or fiberglass, choosing steel doors with foam insulation or magnetic weatherstripping can significantly improve their energy efficiency.

  1. Glass

Doors with glass elements, such as sidelights or windows, add aesthetic appeal but can impact energy efficiency. Opt for low-emissivity (low-E) glass that has a special coating to reduce heat transfer, preventing energy loss and improving insulation.

  1. Composite

Composite doors are engineered using a mix of materials, typically including wood, fiberglass, and/or PVC. They offer the best of both worlds, combining the aesthetics of wood with the durability and energy efficiency of fiberglass or PVC.

  1. Other energy-efficiency considerations

Other than material, there are several other crucial considerations that can enhance the overall energy efficiency of your doors and contribute to significant savings. These often-overlooked factors play a pivotal role in reducing energy consumption:

  1. Proper Installation

A well-installed door ensures a tight seal and minimizes air leakage. Improper installation can create gaps, allowing conditioned air to escape and outdoor air to infiltrate your home. Hiring a professional installer ensures a proper fit and maximum energy efficiency.



  1. Insulated Frames

While we often focus on the door itself, the frame surrounding it also plays a vital role in energy efficiency. Opt for doors with insulated frames to prevent thermal bridging and minimize heat transfer.

  1. Weatherstripping and Sealing

Investing in high-quality weatherstripping materials and effective sealing mechanisms is essential. Weatherstripping should be applied to the door edges and threshold to prevent drafts and air leakage, maintaining a consistent indoor temperature.

  1. Low-E Glass

If your door has glass elements, consider doors with low-emissivity (low-E) glass. This special coating reduces heat transfer, keeping your home insulated and preventing energy loss.

  1. Energy-Efficient Hardware

Don't overlook the impact of hardware on energy efficiency. Choose door hardware that is designed for energy conservation, such as insulated door sweeps and energy-efficient locks.

  1. Strategic Placement

Consider the orientation of your doors and how sunlight affects them. South-facing doors may benefit from shade or awnings to reduce solar heat gain during warmer months.

Combined with energy-efficient materials, proper installation, sealing, and strategic placement, these factors contribute to a more comfortable home and substantial savings on utility bills.

National Fenestration Rating Council (NFRC) vs Energy Star®

Navigating the world of energy efficiency labels can be overwhelming. Two prominent labels that often come into play are the National Fenestration Rating Council (NFRC) and Energy Star®. Understanding the differences between these labels is crucial in making informed choices for maximizing energy savings.

  • NFRC

The NFRC is an independent organization that provides standardized ratings for windows, doors, and skylights. Their label displays important performance measures, including U-factor, Solar Heat Gain Coefficient (SHGC), Visible Transmittance (VT), and Air Leakage (AL). These ratings help homeowners assess a door's insulation, heat gain, light transmission, and air infiltration capabilities.

  • Energy Star®

Energy Star® is a voluntary program by the U.S. Environmental Protection Agency (EPA) and the U.S. Department of Energy (DOE). Energy Star® certified doors meet specific energy efficiency criteria, including U-factor and SHGC ratings. Doors with this label are independently tested and verified to provide superior insulation, reducing energy consumption and utility bills.

While the NFRC label provides detailed information on specific performance metrics, Energy Star® certification offers a more simplified approach by focusing on overall energy efficiency. It's important to note that doors can have NFRC ratings without being Energy Star® certified, as Energy Star® encompasses a broader range of energy-efficient products. When selecting doors for replacement, homeowners should consider both NFRC ratings and Energy Star® certification. Combining the detailed information from NFRC labels with the assurance of Energy Star® certification ensures that you are making an energy-efficient choice that will result in bill reduction and enhanced comfort.

In essence, door replacement proves to be a practical and rewarding investment. By keeping our bills down, enhancing our homes' functionality and aesthetics, and promoting sustainable living, it offers a holistic solution that benefits both our wallets and the environment. So, let us open the door to savings and a brighter future by considering this often underestimated home improvement endeavor.

What is Lorem Ipsum? Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum. Why do we use it? It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
