Step-by-step: Installing InsulDoor insulation on metal garage doors

Why Garage Door Insulation Matters in Australian Homes 

Metal garage doors, while durable, are often the weakest link in your home's energy efficiency. They absorb heat in the summer and let cold air in during winter, making your garage a thermal liability. This is where InsulDoor Garage Door Insulation Kits from The Foam Company come in.

It also adds a layer of soundproofing—ideal if your garage doubles as a workspace or home gym. Made using high R-value materials, the InsulDoor kit combats heat transfer effectively, a must-have for extreme Australian climates.

Tools and Materials Needed Before You Start 

Before you begin your InsulDoor installation, it’s essential to gather the right tools and check your measurements. The DIY garage door insulation guide provided by The Foam Company ensures that you’ll be well-prepared from start to finish.

You’ll need:

• Measuring tape
  
  
• Utility knife or foam cutter
  
  
• Safety gloves
  
  
• Clean cloth for wiping surfaces
  
  
• Roller or adhesive tape (optional for extra grip)
  

Each InsulDoor kit comes custom-cut based on the size you select online, but it’s still wise to measure each panel of your garage door. This ensures a snug fit and avoids air gaps that can reduce insulation effectiveness.

Keep in mind that metal garage doors may have uneven surfaces or frames. Cleaning the inner surface of the panels before installation helps the insulation stick better and avoids long-term slippage.

Pro Tips:

• Double-check the R-value of your kit for your local climate zone.
  
  
• Keep all tools within arm’s reach to maintain workflow.
  
  
• Lay out all foam panels before starting to ensure correct alignment.
  
  

The Foam Company also stocks foilboard insulation panels, but InsulDoor is specifically designed for custom garage door applications, making it the go-to solution for Australian homes.

Step 1: Measure Each Garage Door Panel Accurately 

Accurate measurements are crucial for a proper fit. Although InsulDoor kits from The Foam Company are cut-to-size, some slight adjustments may be needed based on panel shape.

Here’s how to measure:

• Use a tape measure to find the height and width of each internal panel.
  
  
• Subtract 5mm from each dimension to allow for easy fitting.
  
  
• Mark the measurements on your foam panel before cutting.
  
  

Each garage door insulation kit in Australia is engineered to provide a snug fit without adhesives, but tight-fitting panels are key to achieving optimal thermal efficiency and soundproofing.

Common mistakes to avoid:

• Skipping measurements and relying only on door specs.
  
  
• Measuring only one panel and assuming uniformity.
  
  
• Not cleaning the metal surface before fitting foam.
  

Once you’ve measured all panels, use a utility knife or foam-specific cutter to make clean, straight cuts. Doing this on a stable surface helps prevent jagged edges or uneven alignment.

Double-check each piece against its panel slot before moving on to installation.

Step 2: Fit and Secure the InsulDoor Panels

Once your foam pieces are ready, start from the bottom panel and work your way up.

To install:

• Gently bend the foam to fit into the door panel cavity.
  
  
• Press the insulation into place, starting at the edges and smoothing inward.
  
  
• If needed, use low-tack adhesive tape for additional grip—this is especially helpful in high-humidity areas.
  

Thanks to The Foam Company’s precision-cut EPS foam, garage insulation in Australia is easier than ever. No professional installers or heavy tools required.

Each panel sits flush inside the metal frame, adding an extra thermal barrier to your garage. The white finish gives your garage a cleaner, sleeker look without paint or sanding.

Extra Tip:
Use a roller to press down firmly, ensuring the foam is tightly fitted into the panel groove.

Step 3: Review and Perform Safety Checks 

After installation, it's important to test door functionality and assess insulation effectiveness. A well-insulated garage door should move smoothly and feel more solid due to the added panel weight.

Post-installation checklist:

• Open and close the garage door several times.
  
  
• Check that none of the panels shift or fall.
  
  
• Ensure foam doesn’t interfere with hinges or rollers.
  
  
• Touch both the inside and outside of the door to test temperature differences.
  

If your garage is still letting in heat or noise, consider adding garage wall insulation using foilboard panels or additional cut-to-size EPS foam for full coverage.

With your InsulDoor kit correctly installed, you’ll enjoy:

• Reduced summer heat buildup
  
  
• Quieter garage environments
  
  
• A neater and more energy-efficient home
