Insulated garage doors provide comfort, energy savings, sound reduction and a higher property value. Upgrading to an insulated garage door is an excellent way to enhance and protect your indoor space, and purchasing a garage door from a reputable company ensures your door has the highest-quality construction for optimal insulation.

The Top Benefits of Insulated Garage Doors

An insulated garage door can significantly enhance your home and help you save money. Upgrading your garage door to an insulated model offers the following range of benefits:


A well-insulated garage door makes your indoor space more comfortable. With the right door, your garage stays cooler in the summer and warmer in the winter. Whether you enjoy a warm space to get in your car each morning or want to use your garage for special activities and gatherings, having an insulated door helps you maintain a stable temperature.

Energy Savings

In addition to comfort, an insulated door can help you conserve energy and reduce your energy bill. Insulation helps minimize heat transfer, assisting you in maintaining the space's temperature without overworking your heating, ventilation and air conditioning system. An insulated garage door can help do the same for your home's interior if your garage is attached.


Proper temperature control also helps protect the items you store in your garage. While a non-insulated door can keep weather elements such as snow, rain and hail off of your car, an insulated door helps protect your car's engine, fluids and tires from freezing temperatures. It also provides a temperature-stabilized space for storing items such as power tools, electronics, appliances, furniture and sentimental items.

Sound Reduction

Insulated doors operate more quietly than non-insulated doors. They also help block outdoor sounds, giving you a more pleasant space to park, work or gather in.

Selling Point

Having an insulated garage door can be a selling point for potential homebuyers if you decide to sell your home. A new garage door means the homebuyer doesn't have to maintain an older door. Adding insulation provides extra benefits that can make the prospect of a new garage door even more appealing.

Types of Insulated Garage Doors

A garage door can contain one of two insulation types — polystyrene or polyurethane. Understanding how these options differ can help you make an informed decision when you upgrade your garage door:

  • Polystyrene: Polystyrene insulation comes in the form of rigid panels placed between a garage door's steel layers.
  • Polyurethane: Polyurethane is an injectable foam that fills the space between a garage door's layers. It offers more temperature control than polystyrene due to its ability to expand and fill more space within a door's layers.

Choosing between polystyrene and polyurethane insulation depends on how insulated you need your door to be. While polystyrene offers quality insulation for garages in mild climates, a polyurethane-insulated door is ideal for garages in areas with extreme temperatures. Polyurethane is also the perfect option for homeowners who use their garages for additional purposes, such as a work or hobby space.

How High of an R-Value Does Your Garage Door Need?

The best garage door for insulation has a high R-value. R-value is a measurement that indicates how well a door can slow heat transmission, maintaining the air inside your garage. The higher the R-value, the slower heat transfers through a material. A garage door with a high R-value does a better job of keeping your garage cool in the summer and warm in the winter.

Doors with lower R-values allow more heat transfer than doors with high R-values, but they offer effective insulation for garages in mild climates. If you live in an area with harsh winters or hot summers, it's better to choose a door with a high R-value. You should also consider a high R-value if your family uses your garage for various purposes such as storage, gathering, working or playing.

Why Choose Clopay® Insulated Garage Doors

As America's favorite garage door brand, Clopay offers some of the best residential insulated garage doors in the industry. When you purchase a garage door from Clopay, you can expect the following benefits:

Polystyrene or Polyurethane Insulation

Clopay uses polystyrene and polyurethane to manufacture garage doors, providing customers with reliable, long-lasting insulation. The best material for your door depends on the level of insulation you need. While polystyrene is a dependable option, polyurethane is the best choice if you need the highest level of temperature stability.

Clopay Intellicore® insulation technology uses polyurethane foam to offer the greatest insulation available. This foam expands to fill a garage door's every crevice, leaving no room for air leaks. A Clopay Intellicore garage door is the best option if you're looking for the greatest energy efficiency possible.

Industry-Leading R-Values

Clopay garage doors have R-values between 6.3 and 20.4. Polystyrene-insulated doors can have R-values between 6.3 and 10, and polyurethane-insulated doors can reach R-values as high as 20.4 for optimal temperature stability.

4-Layer and 5-Layer Construction

We manufacture doors with 4-layer and 5-layer construction, increasing their insulative capabilities. A 4-layer door includes two steel layers surrounding insulation, and a composite overlay fits on top for beautiful aesthetic appeal. A 5-layer door also includes a composite cladding. Some models also feature glass and aluminum for a sleek look.

Durable steel layers strengthen doors for longevity, and composite cladding and overlay materials provide detailed grain patterns for a natural wood texture and appearance. We mold composite cladding and overlays from real wood pieces to ensure they produce a realistic texture and look.

Thermal Break

A thermal break fits between a garage door's section joints. Thermal beaks prevent energy from transferring from one side of a door to another by separating the door's exterior and interior steel layers. This feature helps to further reduce heat transfer. Many Clopay residential garage doors come with thermal breaks to provide additional temperature regulation.

Various Design Options

Clopay understands the importance of a garage door's visual appeal. To complement your home's architecture and design, we offer various overlay design options, such as the following:
