Discover Which Are the Most Energy Efficient Garage Doors

4th January 2024

Determining the Best Insulated Garage Doors

To choose the most efficient insulated garage doors, it’s necessary to assess factors like U-values, R-values, and the type of garage door. Since lower U-values signify higher thermal efficiency, they are indicative of better insulation.

Sectional and insulated roller garage doors are two of the most energy-efficient choices available. Both have their distinct advantages, but the key is to select the one that best suits your specific needs and preferences:

Sectional Garage Doors

Sectional garage doors offer excellent insulation and sealing properties. Some models boast U-values as low as 0.5 W/(m2∙K), providing superior thermal performance. These doors are designed with a unique “broken sandwich” construction, which ensures thermal separation of the outer and inner shells and results in heat insulation values lower than 0.5 W/m2K.

Furthermore, triple-glazed windows can be added to brighten a dim garage area while maintaining energy efficiency. Ultimately, sectional garage doors are a top choice for those looking to optimise their garage’s energy efficiency.

Roller Garage Doors

Roller garage doors can provide good insulation, but their effectiveness depends on the quality of the materials used and proper installation. To enhance the U-value of a roller garage door, you can install the door behind the lintel and add a full box, which can significantly improve energy efficiency.

Roller garage doors are one of our most popular garage door products, due to their space saving design, insulation benefits, enhanced security, durability and low maintenance requirements.

Benefits of Insulated Garage Doors

The numerous advantages of insulated garage doors include energy savings, enhanced comfort with noise reduction, and improved security. These benefits make them an appealing choice for homeowners looking to improve their garage’s overall performance.

Whether you have an attached garage or use the space for a workshop or home gym, installing an insulated garage door can significantly impact your energy bills and overall comfort.

Energy Savings

The potential to reduce energy loss is one of the benefits of insulation in garage door materials, leading to decreased heating and cooling expenses. The insulation materials used in these doors, such as polyurethane foam, provide high R-values, indicating superior insulation and enhanced energy efficiency. By improving the thermal boundaries and minimising heat loss, insulated garage doors can contribute to lower annual energy bills.

The exact energy saving percentage may vary depending on the level of insulation and the overall energy efficiency of the garage, but the potential savings are well worth the investment.

Comfort and Noise Reduction

By reducing noise levels and stabilising temperatures, insulated garage doors provide a more comfortable environment. The insulation materials used, such as fibreglass, help dampen sound from both inside and outside the garage, creating a quieter environment for adjacent rooms and the surrounding area.

Furthermore, these garage doors can help maintain a comfortable temperature within the garage, making them an ideal choice for those using the space as a workshop, home gym, or office.

Enhanced Security

Due to their solid construction and materials, energy-efficient garage doors often provide greater security. Double-skinned aluminium or steel contributes to the enhanced security of insulated garage doors, providing robustness and protection for your belongings. In addition, these doors feature weather seals that prevent the entry of cold air and retain heat, ensuring the safety of your possessions.

Typical Usage of Insulated Garage Doors

Various scenarios commonly employ insulated garage doors, including garage conversions, workshops and home offices, and attached garages. With their numerous benefits, such as energy savings, enhanced security, and improved comfort, they have become an increasingly popular choice for homeowners looking to optimise their garage spaces.

Understanding how insulated garage doors are typically used can guide you in making an informed decision about the best option for your specific needs.

Garage Conversions

Garage conversions benefit from insulated garage doors in the following ways:

  • Insulated garage doors help maintain consistent temperatures in the converted space.
  • They help meet building regulations for garage conversions.
  • As garage conversions often involve the creation of additional living spaces, insulated garage doors help regulate the temperature and provide a comfortable environment for the new space.

By selecting a garage door with a low U-value, you can ensure that your garage conversion meets energy efficiency requirements and provides a comfortable living area.

Workshops and Home Offices

Workshops and home offices require a comfortable environment, making insulated garage doors an ideal choice. These doors provide improved temperature regulation, helping to maintain a consistent environment throughout the year and reducing noise transmission, creating a quieter workspace for increased concentration.

Furthermore, insulation helps minimise draughts and air leakage, making your workshop or home office more energy-efficient and comfortable.

Attached Garages

Attached garages can impact a home’s energy efficiency, so choosing an insulated garage door is crucial. Insulated garage doors can reduce heat transfer, minimise air leakage, and provide better insulation, ultimately helping to lower energy bills.

By installing a well-insulated garage door, you can ensure that your attached garage remains comfortable and energy-efficient, contributing to a more eco-friendly home.


As we’ve explored, energy-efficient garage doors offer numerous benefits, such as reduced energy costs, increased comfort, and enhanced security. By considering factors like insulation materials, garage door types, and weatherproofing techniques, you can make an informed decision and invest in a garage door that best suits your needs. With the right energy-efficient garage door, you can transform your garage into a comfortable, eco-friendly space that adds value to your home.
