Insulated vs. Non-Insulated Garage Doors: Which is More Energy Efficient?
When choosing a garage door, energy efficiency often becomes a top priority for homeowners. With energy costs on the rise and sustainability becoming more important, the decision between insulated and non-insulated garage doors is no small matter. This article delves into the differences between the two options and helps you determine which type of garage door is the most energy-efficient for your needs.
What Are Insulated Garage Doors?
Insulated garage doors are specifically designed to reduce heat transfer between the interior and exterior of your garage. These doors are constructed with layers of insulating material, such as polyurethane or polystyrene, sandwiched between durable steel or aluminium.
The primary goal of insulated garage doors is to create a thermal barrier, keeping your garage at a more stable temperature year-round. This design offers benefits beyond just energy savings, including better noise reduction and enhanced durability.
What Are Non-Insulated Garage Doors?
Non-insulated doors, on the other hand, consist of a single layer of material, such as steel, wood, or aluminium. While they are often more affordable upfront, they lack the insulating properties of their insulated counterparts.
These doors are ideal for detached garages where temperature control isn’t a concern or in regions with mild weather. However, for homeowners who use their garage as a workspace, gym, or extension of their living space, non-insulated doors may not provide the comfort and energy efficiency required.
Energy Efficiency Comparison: Insulated vs. Non-Insulated
Temperature Regulation
Insulated garage doors are designed to maintain a consistent temperature inside the garage, regardless of outdoor weather. The insulation acts as a barrier, preventing cold air from entering during winter and hot air from seeping in during summer. This can significantly reduce the strain on your home’s HVAC system, leading to lower energy bills.
Non-insulated garage doors, on the other hand, offer no protection against extreme temperatures. If your garage is attached to your home, the lack of insulation can lead to heat transfer into adjacent rooms, forcing your HVAC system to work harder.
Material and R-Value
The R-value measures a material’s thermal resistance, indicating how well it can prevent heat transfer. Insulated garage doors generally have a much higher R-value compared to non-insulated ones.
For example, a garage door with polyurethane insulation may have an R-value between 6 and 20, depending on the thickness and material. Non-insulated doors have an R-value of close to zero, offering little to no thermal resistance.
Noise Reduction bn
While energy efficiency is often the primary concern, noise reduction is another advantage of insulated garage doors. The insulation dampens external sounds, creating a quieter environment inside the garage and home.
Non-insulated doors, being lighter and thinner, tend to vibrate more, amplifying external noise. This can be especially noticeable if your garage faces a busy street or is located in a noisy neighbourhood.
Additional Benefits of Insulated Garage Doors
Durability
Insulated garage doors are constructed with multiple layers of material, making them more robust and resistant to dents, dings, and other damage. Non-insulated doors, being single-layered, are more prone to wear and tear over time.
Increased Home Value
Energy-efficient homes are in high demand. Installing an insulated garage door can be a selling point if you plan to put your property on the market. Buyers often appreciate the added energy savings, noise reduction, and durability that insulated doors provide.
Comfort and Usability
If you use your garage as more than just a place to park your car, an insulated door ensures a comfortable environment. Whether you’re working on hobbies, exercising, or using the space as storage, insulation can make the area more usable year-round.
When to Choose a Non-Insulated Garage Door
While insulated garage doors are often the superior choice, there are instances where a non-insulated door may suffice. For example:
- Detached Garages: If your garage is separate from your home and not climate-controlled, insulation may not be necessary.
- Mild Climates: In areas with consistent, mild weather, the energy-saving benefits of insulation may be less noticeable.
- Lower Budget: Non-insulated doors are more affordable initially, making them a practical choice for homeowners on a tight budget.
How to Maximise Energy Efficiency in Your Garage
Even with an insulated garage door, there are additional steps you can take to improve energy efficiency:
- Seal Gaps and Cracks: Ensure that there are no air leaks around the door edges or frame. Weatherstripping can help seal these gaps.
- Upgrade the Door Opener: A modern garage door opener with smart features can improve efficiency by ensuring smooth and precise operation.
- Insulate Garage Walls and Ceiling: Pairing your insulated door with wall and ceiling insulation creates a fully optimised thermal barrier.
- Use Energy-Efficient Lighting: Replace traditional bulbs with LED lights to reduce energy consumption.
Which Garage Door is Right for You?
When deciding between insulated and non-insulated garage doors, energy efficiency should be a key consideration. Insulated garage doors are the clear winner when it comes to maintaining a comfortable temperature, reducing energy costs, and enhancing durability. Although they come with a higher upfront cost, the long-term savings and added benefits make them a worthwhile investment.
On the other hand, non-insulated garage doors may be a practical option for detached garages or those in milder climates. Ultimately, your choice will depend on your budget, garage usage, and local weather conditions. If energy efficiency and comfort are priorities, insulated garage doors are the superior choice.

Insulated Garage Door FAQS
Can I add insulation to an existing non-insulated garage door?
Yes, insulation kits are available that allow you to retrofit your existing garage door. However, the results may not match the performance of a factory-insulated door.
Do insulated garage doors require more maintenance?
No, insulated garage doors are often more durable and require less maintenance than non-insulated doors due to their sturdy construction.
Are insulated garage doors worth the extra cost?
Yes, if energy efficiency, comfort, and long-term savings are important to you, an insulated garage door is worth the investment.
How can I tell if my garage door is insulated?
Insulated garage doors typically feel heavier and have multiple layers of material. You can also check the product specifications or ask the manufacturer.
Does an insulated garage door reduce noise from the garage?
Yes, insulated garage doors provide better soundproofing by dampening noise from inside and outside the garage, making them ideal for workshops or busy neighbourhoods.
