The Best Types of Garage Door Insulation


When it comes to maintaining your home’s energy efficiency, garage door insulation is often overlooked. At 24H Garage Doors, we understand the importance of a well-insulated garage door—not only does it help regulate your garage's temperature, but it also enhances your home’s overall comfort and energy savings. In this blog post, we’ll explore the best types of garage door insulation, considering factors such as material, R-value, and ease of installation. Whether you’re looking to keep your garage warm during winter or cool in the summer, we’ve got you covered. Let’s dive in!

Polystyrene Insulation


Polystyrene insulation, commonly found in rigid foam boards, is a popular choice for garage doors due to its excellent thermal properties and durability. This material provides a solid barrier against temperature fluctuations, making it ideal for homeowners in regions with extreme weather conditions.
Polystyrene is lightweight and easy to install, often coming in pre-cut panels that fit snugly into the door’s sections. The R-value, which measures insulation effectiveness, typically ranges from 3.5 to 6.5, depending on the thickness of the foam.
In addition to its thermal benefits, polystyrene insulation also offers soundproofing qualities, helping to minimize noise from outside and creating a quieter environment in your garage. This makes it an excellent option for those who use their garages as workshops or recreational spaces. With proper installation, polystyrene can significantly enhance your garage's energy efficiency while adding to its overall aesthetic appeal.

Polyurethane Insulation


If you’re seeking top-tier insulation performance, polyurethane is often regarded as the gold standard. This material features a high R-value, typically between 6 to 7 per inch, making it one of the most effective insulators on the market. Polyurethane insulation is injected between the garage door panels, providing seamless coverage that minimizes thermal bridging and air leaks.
The benefits of polyurethane go beyond just insulation. Its density offers excellent sound-dampening properties, making your garage a quieter place to work or unwind. Additionally, this type of insulation is more resistant to moisture and pests, providing long-term durability.
However, installation can be more complex than polystyrene, often requiring professional help. At 24H Garage Doors, we have the expertise to install polyurethane insulation correctly, ensuring your garage door performs at its best. Although it may come at a higher price point, the energy savings and comfort provided by polyurethane insulation can be well worth the investment in the long run.
