How to Insulate Garage Doors?

Keeping heat inside the home is important when it comes to saving money on our energy bills. However, this can be difficult in homes that have garage doors because they don’t tend to be insulated. So, whether you plan on sitting in your garage more often or reducing your energy bill, you should know how to insulate. Luckily, the process is extremely simple and you won’t need to call in a mechanic. Below, we will tell you everything you need to know about insulating your garage door.

Should You Insulate?

Garage doors are the largest entry point for heat and can shoot your heating bill skywards if you’re not careful. If you live in an area with extreme winter conditions or abnormally high energy prices, you should consider adding insulation to keep yourself warm and bring down the price of your energy. As a bonus to getting your door insulated, you will dampen excess noise from outside of your home.

Different Types of Insulation

No matter what insulation you use, your energy bill will be decreased. However, some work better than others:

  • Reflective Insulation. This is applied to insulation on one or both sides. The reflective properties of the aluminum will radiate heat and keep your energy bills low. This type of insulation is a great idea for all-year insulation needs. You will typically spend around $45 for a 25-foot roll.
  • Batt Insulation. Commonly used on interior walls, this insulation is usually made of fiberglass. The insulation will be sandwiched between foil or paper, which makes up the defense against harsh weather conditions. You will pay $0.30 per square foot.
  • Foam Board Insulation. Foam board is a type of rigid insulation that offers fantastic insulation without needing to be too thick. Once you’ve applied the insulation, you will need to back it with vinyl or aluminum foil. You will pay £20 for an 8-foot roll of 1-inch thickness.

When you choose your insulation, you need to make sure that it’s not applied too thick. If your insulation turns out to be too heavy, your garage door will struggle to serve its purpose and can cause damage to the door.

Choosing the Correct Insulation

The type of insulation you use will depend largely on your door and the climate you live in:

  • Flat garage doors. If your garage door has no panels, you should use reflective or foam board insulation. In the absence of struts, you will need to tape the insulation directly to the garage door.
  • Wooden frame or panel doors. These doors are extremely versatile and will take any insulation you throw at them. If you live in adverse weather conditions, you should layer up the insulation for better control.
  • Steel doors. Steel doors are similar to wooden frame garage doors because you can use any insulation you like. The edge that steel has over wood is that there’s more initial protection and doubling up isn’t always necessary.

Clean Your Door

Once you’ve chosen the type of insulation you’re going to use, you need to clean your entire door. Primarily, you need to be removing dust from the struts of the garage door because this is where your adhesive tape is going to be placed. If there are particles between the tape and the struts it will struggle to seal and stay down.

Double Tape

Once you’ve cleaned the door and dried it completely, you need to grab a roll or two of strong double-sided adhesive. You need to apply it to the entire face of the struts without removing the backing. Once the tape is in position, you need to seal it up with pressure using your hand or a squeegee.

Now that your tape is secured and you’ve got your chosen insulation at the ready, it’s time to peel off the backing paper. Make sure that you don’t stick anything else to the tape, otherwise, you’ll need to start again.

Attach Insulation

Now, you need to lay your insulation in the correct place and secure it firmly to the tape. At this point, you don’t need to worry about everything fitting perfectly because you’ll tidy things up later. However, while you’re sticking the insulation to the tape, you will need to cut around the hinges so that your door will still function properly. Once the entire door is completely covered and sealed through, you need to trip the insulation so that it all looks professional.

To Finish

All you need to do in this step is seal up any gaps with some form of aluminum tape, which will help to keep your energy bill down.

Keeping your house warm is essential for keeping energy costs down, and having a garage can hinder your efforts. Therefore, if you want to save yourself some money while keeping the noise down, you should follow this guide and insulate your garage.
