Cheap Ways To Insulate A Garage Door

How to Insulate a Garage Door THE RIGHT WAY!

Is your garage letting in too much heat or excessive cold? Standard metal doors do very little to regulate the temperatures inside the garage. An insulated door can set you back an upwards of $1400.

But, if you do not want to break the bank buying a new model, consider insulating your existing one with inexpensive foam board or fiberglass batting. Below, we show you how to insulate a garage door cheaply plus recommendations on making the project a success.

Measure And Mark The Garage Door

The second step will have you measure your garage door panels. Measure the space vertically and horizontally between the frame. In the following steps, you will need these measurements to cut your insulation to size. Depending on your individual garage door, it can include anywhere from four to nine separate panels clearly defined by the interior garage door frame.

Also, mark out where you are going to install your retainer clips. Each panel will take two clips. These marks should be at least 12 inches from the nearest rail and be vertically centered for the best results. Use a pencil, pen, or marker. Make sure the mark is clearly visible, as you will need to reference it in the next step.

Set Up The Retaining Pins

The biggest advantage of pre-packaged batting kits is their retainer pins. Made of plastic or metal, these pins have a wide base with adhesive at the back so you can stick them on the garage door to hold the insulation in place when the door is open.

  • Stick a retainer pin at the center of each panel. For correct positioning, measure the length of the panel, find the middle point then firmly stick the pin. Repeat this until there is a pin on all the panels.
  • For a flat-faced garage door, simply install enough pins all over the door to support the number of batting pieces you will install. For best results, space out the pins evenly.

Insulated Garage Doors Help You Save On Energy Costs $$

Unless you turned your garage into a spare bedroom, you probably didnt install a heater vent inside. Even so, the heat from your home can escape into the garage and get sucked right out through a poorly insulated garage door. This energy loss can keep your heater on for extended periods of time. The inside temperature wont reach the thermostat setting to trigger the automatic shut off.

The amount of heat escaping through your garage may not be enough to make a significant impact each month, but will add up over time. The key to saving on energy costs is to reduce your energy waste everywhere you can because it does add up. Consider that saving just $10/month on your energy bill saves $120/year. That money could be used for a home repair, taking your family out to eat, or paying off debt.

Fiberglass insulation comes in different R-values, which measure how well certain building insulation materials resist heat. The greater the R-value, the greater the ability to insulate.

Choosing The Right Insulation

Before learning how to insulate a garage door, its important to know about insulation R-values. R-value measures the effectiveness of a type of insulation. Typically, a higher R-value means better climate control and better energy efficiency for your home. Insulation R-values vary based on the type, thickness and density of the insulation material. The total R-value of your insulated areas can increase as you stack layers of insulation.

A high R-value for your DIY garage door insulation will keep your garage warmer in the winter and cooler in the summer. High R-value insulation, however, is often more expensive than low R-value insulation. To best insulate your garage and stay within budget, choose your insulation type based on the type of garage and garage door you have.

Follow these tips to choose the right insulation for your garage door:

Insulate The Rest Of The Garage Instead

Garage door insulation is of limited value anyway, given the other areas of the garage that are equally problematic in terms of energy loss. The floor of your garage is probably built on a slab, which means that it isn’t insulated and is an ongoing source of energy transference. If your garage has concrete walls, these, too, are constant sources of transference. If you do take the time and spend the money to insulate garage doors, you may well be disappointed by seeing a very minimal improvement on your energy bills because thermal energy is still lost in other areas.

Rather than attempting to insulate the garage door and other components of the garage itself, a much more effective solution is to focus your attention on the boundary walls between the main house and the attached garage. By doing so, even if the temperature fluctuates inside the garage, it won’t significantly affect the temperature inside your home or raise your energy bills. Here are the best ways:

  • Put insulation into the ceiling of the garage so it helps stop the loss of energy to the space above, where it may connect to the house attic or a room above the garage.
  • Add plenty of insulation on the interior wall of the garage that’s shared with the house itself.
  • Eliminate air gaps before insulating by taking a can of low-expanding spray foam around the garage to seal all the gaps and cracks to the outside, especially along any windows.

Benefits Of Garage Door Insulation

Its light so it doesnt add much weight, and it contributes to the stability of your garage door since it bonds to the front and back panels.

Doors padded with polystyrene, such as Models 8100 and 8200 of our Classic Steel Doors, offer a moderate R-Value between 3.5 and 7, whereas Models 8300 to 8500 feature liquid polyurethane insulation with R-values of 12.12 and 16.22.

NOTE: Our Premium Steel Doors are made with heavy 24-guage steel, lending even more thermal protection. uses this, plus gives the option of double insulation and a second layer of steel for an R-value of 14.

Glass Panel Garage Doors, such as our Modern Glass Doors, are insulated by filling the grid rails and stiles with liquid polyurethane. This will bring the R-Value to just over 4, which is perfect for mild year-round temperatures in places such as Kelowna.

Windows can also insulate the windows on your garage door, which is handy if you live in an extreme climate or if youve opted for a door with lots of . Double-pane windows already ups the R-Value. In some cases, you can even fill the space between the panes with argon gas for an extra wallop of insulation.

Choose The Best Garage Door Insulation

Before heading over to the home improvement store to pick up supplies, consider which type of product is best for insulating your garage door. The best choice depends on your climate, garage location, and type of door. Insulating capability is measured in R-values the higher the R-value, the more resistant it is to changing temperatures. Therefore, those in colder regions should use insulation with a higher R-value.

  • Wooden and uninsulated metal garage doors insulate poorly relative to modern steel garage doors. If you have either of those types, insulating them should be a top priority for home energy efficiency.
  • For wooden doors, rigid insulation panels work best, but you can use virtually any type of insulation for metal doors.
  • Detached, unheated garages will be fine with low R-value insulation anywhere between R-0 and R-6. As long as you dont use the space for lounging, you dont need to insulate it extremely well.
  • Attached, unheated garages need R-7 to R-9 insulation, since climate control in this space affects the homes heating bill.
  • Use R-10 to R-13 for heated garages to prevent costly heat from escaping.
  • Any garage with living space above it should have R-14 insulation on the door.
  • Garage door insulation kits include pre-cut insulation and fasteners. Some also include gloves and utility knives.
