Insulated Garage Doors: What You Need To Know

Before purchasing a New Garage Door many people shop for price. The problem with this method is that when buying a garage door, it is an investment that can either last you a long time with no problems or become a hassle.

Some things you should consider before your investment is location, durability, noise and finally money.

If your garage acts like a shed, detached from your house or not visible from the road, a non-insulated door may be what you are looking for. It is relatively inexpensive compared to insulated or custom doors. If there is nothing that needs to be climate controlled in your garage and you use it a couple times a week, this will be a good investment for your home.

If your garage door is attached to your home and you use it more often than your front door (believe it or not most people do) than an insulated garage door is something you would want to invest in. One should be educated on what to look for while shopping for an Insulated Garage Door.

The effectiveness of the insulation is expressed as an R-value. The higher the R-value, the better the insulation in the door. This R-value can help you decide on the door especially in what type of region you live in. If you live in a warmer climate, the R-value might not be as important to you as the other benefits insulated doors. If you live in a colder climate area than the R-value can mean everything to you.

R value is the measurement of insulation. To give an example of an R value, a standard wall in a house has an insulation R value of about 11. To ensure that your garage is insulated properly, you will want to find an insulated door that meets or exceeds the R value of the walls surrounding it.

The location of where your garage door is important to think about. If the door is located underneath a bedroom or to the side of a living space that you use often, you will want to consider the noise that the garage produces while being opened or closed. Insulated doors because of how they are made tend to make less noise compared to non-insulated garage doors. While the door is going up and down the door actually absorbs some of the vibration of the moving parts make it less noisy. They also tend to be more attractive than non-insulated doors.

Insulated Doors are also more durable than non-insulated doors. Non-insulated doors are the "beer cans" of the garage door business. They are made with only one sheet of metal. Very easy to dent and crease. Insulated doors can come with several different types of insulation that fill the garage door. The doors can come in Expanding Polyurethane foamed-in-place insulation or Sheet Polystyrene insulation.

Polystyrene Sheet Insulation

Polystyrene Sheet Insulation

Polystyrene insulation comes from sheets of insulation that fill the gaps in the garage door and is then sandwiched together between front and back panels. There is an option to not have a back panel put on but it's not a requirement. The estimated R value for these doors ranges from 3.7 - 7.4(Left picture shows pan door without insulation, right picture shows with Polystyrene insert)

Expanding Polyurethane foamed-in-place Insulation

Polystyrene Foam Insulation

Polyurethane provides greater insulation than Polystyrene Insulation. Polyurethane is injected into the door cavity in liquid form which allows it to fill up all gabs and spaces. This ensures a higher R value and higher quality door. The estimated R value for these doors is 11 and above.
