In the heart of summer, with temperatures soaring well above 100°F, Carl, a homeowner from Lincoln, NE, faced a frustrating issue. His garage felt hotter than the outdoors. Even with vents and fans, it remained a furnace warping plastic bins, spoiling stored paint, and turning his space into a sauna. That’s when he called us at Boys Town Garage Door Repair Co. for a solution. We recommended upgrading to insulated garage doors, and within days, Carl noticed a huge drop in indoor temperature, by as much as 20°F.
Extreme summer heat can take a serious toll on homes in Nebraska, especially those with attached garages. Research shows that uninsulated garages can reach temperatures up to 120°F, driving up energy bills and making the space virtually unusable. With proper garage door insulation, homeowners can reduce heat buildup, lower cooling costs, and better protect their valuables, vehicles, and families from harsh summer conditions.
At Boys Town Garage Door Repair Co., we specialize in helping homeowners and businesses across Lincoln, NE, find the best garage solutions. This guide explores the real-world benefits of insulated garage doors, explains the science behind garage door insulation, and helps you decide which materials, styles, and insulation types are right for you.
What Are Insulated Garage Doors?
Insulated garage doors are multi-layered doors designed to minimize thermal transfer, the process by which heat moves through materials. Unlike non-insulated doors, which are typically single-layered and made from steel or aluminum sheets, insulated doors contain two or more layers of metal surrounding a core made of insulating materials like polyurethane, polystyrene, or rigid foam.
These doors offer a significant U-value reduction (how much heat passes through a material) and increase R-values, which measure resistance to heat flow. A higher R-value means better heat insulation, which is essential for maintaining a comfortable garage space during hot summers and cold winters.
Insulated garage doors come in various door types, including sectional doors, single doors, craftsman garage doors, and even high-end brands like Clopay garage doors, Amarr garage doors, and Martin garage doors. They can be made from steel, aluminum, fiberglass, or wood, offering a wide range of insulation kits, materials, and cost options.
Why Heat Is a Serious Problem for Uninsulated Garages
1. Extreme Temperature Build-Up
Uninsulated garage doors act as a gateway for outdoor temperatures to invade your garage. In the summer, this means your garage temperature can exceed 120°F, especially when the sun directly hits the garage door panels. This heat transfer isn’t just uncomfortable, it’s dangerous. The heat often seeps into your home through shared walls, making your air conditioner work harder, which raises energy bills.
2. Damage to Stored Items and Tools
Many homeowners store items in the garage space, including tools, paints, cleaning supplies, seasonal decor, and even dry goods. Intense garage heat can damage or melt plastic containers, spoil paint, and warp wood. Electronics stored in garages can also suffer from overheating and reduced lifespan. Garage door insulation creates a thermal barrier that helps regulate temperature and protect stored belongings.
3. Car and Equipment Degradation
If you park your car in the garage, heat can harm critical vehicle components. High temperatures degrade battery life, affect tire pressure, and damage finishes. Additionally, appliances like garage refrigerators, freezers, or dryers struggle to operate efficiently in high heat. Insulating your car garage door protects your vehicle and equipment investment.
The Benefits of Insulated Garage Doors in Hot Weather
1. Improved Temperature Regulation
The primary benefit of insulated garage doors is temperature stability. The insulation materials used, such as urethane, polystyrene, or foam panels, reduce heat transfer and maintain a comfortable environment inside your garage. This makes it usable year-round for hobbies, home gyms, storage, or even offices.
2. Significant Energy Savings
Insulated garage doors reduce the workload on your home’s HVAC system. If your garage is attached to your home, heat from the garage can easily penetrate the house. With garage door insulation, you minimize energy loss, reduce cooling demand, and enjoy measurable energy efficiency. Over time, this leads to noticeable energy savings and a better return on investment.
3. Noise Reduction for a Quieter Home
An insulated door offers excellent noise reduction, dampening sounds from both outside and inside. Whether it’s loud neighbors, busy roads, or your garage door opener, the extra layers of insulation keep your home quieter.
4. Enhanced Durability and Lifespan
Insulated doors are generally more durable due to their multi-layer design. Materials like steel and fiberglass are reinforced by insulation cores, resisting warping, denting, rust, and corrosion. These products also last longer with less maintenance compared to thin, non-insulated doors.
5. Boost in Home Value and Curb Appeal
Upgrading to insulated garage doors is a valuable investment in your property. Modern door styles, finishes, and customizable options increase curb appeal and show buyers your home is energy-efficient. Whether you choose Chamberlain garage doors or go for a custom insulated door, you’re adding both beauty and practicality.
Understanding R-Value, U-Value, and Thermal Efficiency
When shopping for an insulated garage door, you’ll encounter technical terms like R-value and U-value. These are important for understanding energy efficiency:
- R-value measures resistance to heat flow. Higher values (R-10 and above) offer superior insulation.
- U-value measures how much heat passes through a material. Lower values are better.
To handle rising temperatures in Lincoln summers, aim for doors with high R-values and low U-values. Choose materials like polyurethane foam, which fills door cavities completely, providing better insulation than polystyrene panels.
Common Insulation Materials Used in Garage Doors
Polyurethane
- High-density foam sprayed into the door
- Provides excellent R-values and structural strength
- Ideal for extreme summer and winter weather
Polystyrene
- Solid foam panels are placed between the door layers
- Moderate insulation at a lower cost
- Good upgrade from non-insulated garage doors
Batt Insulation and Rigid Foam Kits
- Often used in door insulation kits
- Installed post-manufacture for added thermal barrier
- Ideal for DIY upgrades or retrofitting existing doors
Real-Life Results from Our Clients
One Lincoln business owner used their garage to house a home printing operation. Without insulation, the space became unusable by midday. After installing polyurethane-insulated sectional doors, interior temperatures stayed below 80°F even during peak heat.
Another homeowner converted their garage into a kids’ playroom. After replacing their thin steel garage door with an insulated aluminum door, they reported better temperature control, no drafts, and reduced reliance on fans and portable air conditioners.
Types of Insulated Garage Doors
There’s a wide range of garage door types that support insulation:
- Sectional Garage Doors – Most popular for homes; highly customizable with high R-values

Is the Investment Worth It?
While insulated garage doors can cost more upfront, the long-term savings, durability, and increased energy efficiency more than make up for the difference. You’ll spend less on cooling, protect your home and belongings, and enjoy a better-functioning, quieter, and more comfortable garage space.
Whether you’re battling heat in summer or cold in winter, these energy-efficient doors go a long way in improving your quality of life.

Frequently Asked Questions (FAQs)
1. Can I install insulation on my garage door instead of replacing it?
Yes, you can use garage door insulation kits with materials like rigid foam or reflective panels to improve your current door’s insulation, though the performance won’t match a factory-insulated door.
2. Do insulated garage doors help in winter as well as summer?
Absolutely, insulated doors maintain a more stable temperature year-round, keeping cold air out during winter just as effectively as they block heat in summer.
3. Will an insulated garage door make my garage suitable for a living space?
While it significantly improves comfort, turning a garage into a livable space also requires sealing, ventilation, and meeting local building codes.
4. How long does an insulated garage door typically last?
With proper maintenance, an insulated garage door can last 15 to 30 years, depending on material, usage, and exposure to weather.
