When we got a call from a family in Spring, TX, they were sweating literally. Their garage, attached to their home, felt like a furnace every afternoon. The summer heat had turned it into a sweltering space, making their energy bills spike and their home uncomfortable. After inspecting their old non-insulated garage door, we recommended a polyurethane insulated garage door with a high R-value. Once installed, the difference was like night and day. Their garage space stayed cooler, the house felt more comfortable, and their next utility bill was noticeably lower.
According to the U.S. Department of Energy, up to 30% of energy loss in homes occurs through garages, especially those that are attached to climate-controlled areas. In the Texas heat, that loss can translate into hundreds of dollars annually. And it’s not just about your comfort. Your car, tools, and stored items are at risk when temperatures soar.
That’s why selecting the right insulation type and R-value for your garage doors is a smart, long-term investment. At Crockett Garage Doors Co., we want to help you understand how to make the best choice for your home’s energy efficiency, comfort, and wallet.
What Is R-Value and Why Does It Matter?
R-value is the number that represents how well insulation materials resist thermal transfer in simple terms, how well your garage door keeps heat out during the summer and holds warmth in during the winter. The higher the R-value, the better the insulation. Think of it like a barrier against Texas’s scorching temperatures.
Insulated garage doors are available in a wide range of R-values, typically from R-6 to R-20. If your garage space is attached to your house, especially near a kitchen or bedroom, choosing a higher R-value is crucial to prevent energy loss.
By choosing the right garage door insulation, you also increase your energy efficiency, reduce noise from outside, and make your garage a more usable space all year long. Whether you’re working out, doing laundry, or just want to protect your car, the right insulated garage door goes a long way.
How Texas Heat Affects Your Garage
In Liberty, Spring, and throughout Texas, it’s not uncommon for outdoor temperatures to reach 100°F or more. Without the right garage door insulation, that heat quickly transfers into your garage. If your garage is attached, that warmth seeps into your home, pushing your AC to work harder.
A hot garage isn’t just uncomfortable, it can damage your belongings. Items like:
- Paint, adhesives, and cleaning products degrade under high temperatures.
- Power tools and electrical equipment are prone to overheating or corrosion.
- Car batteries, tires, and interior materials age faster.
- If you store food, pet supplies, or electronics, they could spoil or malfunction.
Having an insulated door acts as a protective barrier, reducing thermal transfer and maintaining a more stable temperature. And in the winter? That same insulation helps trap heat, reducing the cold draft that makes your garage space unbearable.
Ideal R-Value Range for Texas Homes
In Texas, choosing the right R-value for your garage door is essential due to our extreme climate. Here’s a more detailed guide based on your needs:
🔹 R-6 to R-9
- Ideal for detached garages where comfort and temperature control are less of a concern.
- Lower initial cost, but limited energy savings.
- Common in basic door insulation kits or single-layer sectional doors.
🔹 R-10 to R-13
- Best for attached garages or garages sharing walls with climate-controlled areas of the house.
- Offers solid thermal resistance and good energy efficiency.
- Suitable for those using garages for storage or limited daily use.
🔹 R-14 and Above
- Recommended for multi-use garages: gyms, workshops, laundry rooms, or hobby spaces.
- Maximum noise reduction, temperature control, and energy savings.
- Great for new garage doors with thick foam insulation and multi-layer steel panels.
Most of the garage doors we install at Crockett Garage Doors Co. feature polyurethane foam insulation with R-values ranging between R-13 and R-18, ideal for managing the Texas summer heat and keeping your garage space comfortable year-round.
Types of Insulation Used in Garage Doors
Understanding insulation types is just as important as understanding R-values. Here’s a closer look at the most common materials used in garage door insulation:
🧊 Polystyrene Insulation
- Similar to rigid foam boards used in coolers.
- Inserted as panels inside the garage door.
- Offers decent insulation (up to R-10).
- More affordable, but doesn’t seal gaps as tightly.
- Common in insulation kits and entry-level garage doors.
🔥 Polyurethane Insulation
- A high-performance foam that’s sprayed between door panels and expands.
- Delivers better energy efficiency and noise reduction.
- R-values up to R-18 or higher.
- Enhances garage door strength and reduces vibration.
- Common in premium insulated doors like Amarr Garage Doors, Clopay Garage Doors, and Martin Garage Doors.
🧱 Batt Insulation and DIY Kits
- Often used in garage door insulation kits from hardware stores.
- Less effective than factory-installed insulation.
- Great for retrofit projects or quick fixes on older garage doors.
Additional Garage Door Features That Boost Energy Efficiency
While R-value is essential, other features also play a role in how well your garage door insulates:
🧰 Multi-Layer Construction
- Doors made with steel, foam, and an interior layer are more efficient than single-layer aluminum or wood doors.
🌬️ Weatherstripping
- Top, side, and bottom seals reduce air leaks.
- A must-have for maintaining a consistent garage temperature.
🪟 Insulated Windows
- Choose double-pane or low-e glass if your garage door has windows.
- Prevents solar heat transfer without sacrificing natural light.
🔊 Noise Dampening
- High-quality insulated garage doors also reduce outside noise—great if you live on a busy street.
🔌 Opener Technology
- Use a compatible garage door opener with a smart logic board for smooth, quiet operation.
- Brands like Chamberlain Garage Door and Craftsman Garage Door often pair well with insulated units.
