How to Install Garage Door Insulation?

Garages tend to house some of our most valuable possessions, so it’s important to look after them. Your garage will help increase your property value considerably if you decide to sell, which means you can reclaim around 75% of your initial investment. Despite garages adding value to the house, we often forget about how cold they are, even if we’ve insulated the walls themselves. The garage door is the largest draught point and will make the room considerably cold. Therefore, it’s important to insulate the garage door itself. Doing this will help save on energy bills and will increase the security of the door. Continue reading to find out everything you need to know about the installation process.

Types of Insulation

There are three main garage door insulation materials, which all have pros and cons. However, you need to choose one of the following before we get started:

  • Reflective insulation comes in rolls and will have aluminum foil applied to one or both sides of the insulation material, which is usually cardboard or polyethylene. The reflective qualities of this material make it excellent at retaining heat and has an R-value of up to 6.
  • Batt insulation is the name given to fiberglass insulation, which comes in flexible rolls. Batt insulation is easy to cut to shape and there is barely any wastage because cut fiberglass can be reused. This insulation has an +R-4 rating for every inch of material. This material contains plenty of irritants, so ensure you use the correct PPE.
  • Foam board insulation is typically made of polystyrene and comes in sturdy boards. When you cut the boards down to size, you need to ensure 100% accuracy to avoid wasting material and money. Although being more technical to fit, they are an excellent choice of insulation for your garage door. In some circumstances, you may need to add reflective foil to one side of the insulation.

Match Door Type to Insulation

Unfortunately, we don’t live in an ideal world, so you can’t just choose the most affordable option. You will need to choose your insulation based on your garage door:

  • For wooden doors, the best option is rigid insulation with foam board used to fill any gaps.
  • If you have a flat door, you can use either foam board or reflective insulation. To secure the material, you should use strong tape or glue.
  • For people lucky enough to have steel garage doors, you can get away with using any insulation. However, you need to make sure the springs are capable of holding the added weight.
  • Panel doors call for a rigid insulation option like foam board.

Shop Around

Before gathering your tools and buying your insulation, you need to think about which product to buy. There are tons of options out there and it can be difficult to cut through the noise. If you’re wanting to do the work yourself to save money, you should buy an insulation kit. With a kit, you don’t need to worry about having the correct tools because they will include:

  • Gloves
  • Adhesive tape or glue
  • Suitable cutting knife
  • Insulation board that you may need to cut down

The above equipment is just a benchmark, so you will need to check with the supplier to make sure these are provided. Although this will save you money, you can just buy the insulation if you already own the tools.

Insulation Installation Process

If you buy a kit, there will usually be instructions inside. Below are instructions for batting insulation:

  1. Washing. Having debris or oil build-ups can hinder the insulation process.
  2. Measurements. Using a tape measure, you need to work out how much batting you need. You can’t measure one panel and apply it to all because they all differ slightly.
  3. Pins. You need to find the midpoint of each panel and mark it with a pen. Then, take two pins and push them into the bottom.
  4. Batting. Vinyl side down, mark out the measurements you took for the panels, adding an extra inch to the height. After cutting the sheet, push the batting onto the pins and replace caps.
  5. Tacking. Apply weather stripping from the top corner and the inside doorstops. Then, push the door to check for movements. If the door is sturdy, fully secure the nails.
  6. Sealing. Your door might have a bottom seal. If it does, you should replace it for the best results.
  7. Testing. Move the door and check that you get a full range of motion. If something is wrong, you may need to make adjustments. Contact a professional if you can’t solve the issue.

Garage door insulation will add value to your home and help save on electricity. You should buy the correct insulation to match your door. The easiest way to install insulation is to invest in a kit that includes all the tools. Follow the contained instructions and contact a professional if you get stuck.
