Garage Door Insulation

Customers often wonder if they should purchase an insulated garage door. One would think that a non-insulated garage doesn’t need an insulated garage door. Is it just a waste of money?

Let’s start with an easy scenario. You have a room above your garage, your garage is built in to your house or you use your garage as a workshop. If this is you then you absolutely need a garage door with the highest level of insulation possible. You can find garage doors that advertise all kinds of R-Values (measure of insulating effectiveness) but buyer beware. Make sure you ask the following questions:

  • I there a seal between the sections?
  • Is there a thermal break between the sections?
  • Are you contemplating a window in your garage door? Keep in mind adding a window section will invariably result in heat loss. You want to get double pain insulated glass.

If your garage is detached, on the side of your house or on a shed, you should still consider an insulated garage door. Non-insulated garage doors are merely a sheet of unsupported steel. In our Canadian climate, all it takes is an ice or wind storm to damage your new garage door beyond repair. Further, should the door stick to the ground as a result of freezing, you run the risk of your electric garage door opener ripping the top section of your garage door.

The good news is upgrading to an insulated garage door can be as inexpensive as an additional $100. This is money well spent. Your investment will pay itself back.

Garage door insulation comes in two primary options; polystyrene (styrofoam) and polyurethane (spray-foam). Polyurethane garage doors will have a higher R-Value. A garage door salesperson can explain all of the differences and make a recommendation.

Maintaining Your Insulated Garage Doors

In addition to replacing your garage door with an insulated garage door, it is very important that you maintain your garage weatherseal / weatherstripping and bottom seal in good condition. Your garage door weather stripping forms a perimeter seal around your garage door. This helps to keep drafts out. You want to keep your weatherstripping in good condition free from cracks and tears. Similarly, the bottom seal / bottom rubber on your door helps to provide a seal between the ground and your garage door. It is important to note that if the ground beneath your door is uneven, this bottom rubber may not provide a perfect seal. Replacing your damaged bottom rubber or garage door weatherstripping can make a meaningful impact on the temperature inside your garage.

Finally, customers ask if we recommend an over the counter garage door insulation kit from the box stores. Of course the decision is yours but we don’t recommend it! These kits can add weight to your door creating more wear and tear on your electric garage door motor, garage door spring and can make your garage door imbalanced.

In summary, we highly recommend you purchase a garage door with some level of insulation. The additional charge is often insignificant and the benefits are numerous.
