How to Save Energy with Roller Garage Doors

Opening and closing the garage door isn’t something most people even think about. After all, it’s just opening and closing a door, right? Well, that’s partially correct. Opening and closing your garage door is unavoidable, yes, but its the type of garage door you’re opening and closing that makes all the difference.

There are two conventional types of garage doors; sectional and roller garage doors. While most people in the U.S. use sectional doors, roller doors can actually save energy, and therefore money.

To help get you started, we’re breaking down exactly how roller garage doors can save you money.

Sectional Versus Roller Garage Doors

First thing’s first. We need to touch on the difference between sectional and roller doors. They’re fundamentally different in how the mechanically operate and how they’re designed. And those difference affect how much energy you can save.

Sectional garage doors consist of, surprise, sections. Each section represents a substantial part of the door, which is attached to one another by hinges that allow the door to flex when it gets “put up.”

These doors attach to a track that runs along the garage ceiling. When the door goes up it slides along the track and up along your ceiling. Sectional doors are commonly made of plastic.

Roller garage doors differ in that they roll into your ceiling. Each door comprises itself from smaller, metal or nylon slats that connect on small hinges. Each slat can roll to eventually collapse the door into a cylinder upon opening.

Besides just saving money on energy, roller doors also save space on the garage ceiling thanks to their compact design.

How Roller Garage Doors Save Money

Roller garage doors, as we mentioned above, save money through saving energy. The first difference we already touched on, though didn’t address. Roller doors are metal or nylon.

Compared to their preeminently plastic counterparts, nylon roller doors keep significant heat inside your garage. Metal actually lets more heat escape than plastic, but because of this, metal doors usually come with insulation by default.

While the nylon doors might keep heat better, it’s usually not worth nylon’s shorter lifespan. Any heat loss from metal doors is easily mitigated with a few tweaks.

Which leads us to our first point…


Roller garage door slats are two pieces of either nylon or metal that attach to form one single slat. This leaves room between the two halves of each slat for air. In mild climates, the air works well as insulation, but in colder climates, or just for those looking to save more money, there’s a better alternative.

The space in-between each slat is the perfect place for additional insulation. A hard foam that seals off even the smallest cracks to keep the cold out and the heat in. Likewise, the best-quality insulated doors have insulation that covers roller door seams and creases.

When paired with nylon, and even metal, slats the potential for energy saving is tremendous. How?


Keeping in the Heat

Most garages fall into two categories, workspaces or car storage. Though some fall under both. In either instance, you’re likely heating the space during the colder months, even if inadvertently.

While you might not heat a garage used for simple car storage, that garage is still connected to your home. Any door between your garage and home will let heat out of the house and into the garage.

Heat flows from hot to cold, which means all that heat in the warm house is trying to find its way into the cold garage. That’s another issue but is still related to the garage door. If you’re losing heat to the garage, you’re also losing that heat out of the garage door.

Think of it like a cycle. Heat goes from the home, into the garage, and out the garage door. More heat then moves into the cold garage and the cycle continues. Keeping the heat in the garage is the best way to stop the problem.

That’s where roller garage doors come into play. Insulated doors keep the heat in the garage and so you don’t keep losing heat from the home. Less heat loss means less energy used.

And Keeping the Cold Out

While heat moves from cold to warm, you can also lose air conditioning from your house into your garage. And just like with heat, that cold air escapes through your garage door.

An insulated door can help minimize the cold air lost through your garage. Likewise, heat can also come into the garage and then home through an uninsulated garage door. That makes your air conditioner run harder and wastes energy.

Choosing Your Roller Garage Doors

Choosing an insulated roller garage door means selecting what works best for your needs. This means determining what exactly kind of roller door you need, how much insulation you need, and even what application you’re using the door for.

Is the door to your home (as we mentioned before)? How about for a workshop (which you’ll likely heat and cool)? Each door comes with different positives and negatives that you should discuss with a specialist.

Though regardless of what door you choose, know that any roller garage doors can save you on your energy costs and therefore money.
