Your humble garage door does a lot more than you might think. Not only does it keep your valuables secure and reduce the level of outside noise, but it also offers you protection against the Australian elements.

However, the degree of protection that you’ll enjoy against cold and heat will depend on the type and quality of your garage door insulation. This means that you’ll want to determine all the pros and cons about garage door insulation before you make an investment.

Considering that insulating your garage door can help you to double up the use of available space, it might make much more sense to spend a couple hundred dollars on making this home improvement instead of tackling a more expensive renovation project. So, let’s dive in and figure out whether insulating your garage door is worth it for your unique needs.

How does garage door insulation work?

When it comes to garage door insulation, you might be surprised to learn that there are a number of different ways that you can insulate it. Fibreglass batting, cellulose fibre, and rigid foam panels are the three main types of material that can be used for this project.

Fibreglass batting

When opting for fibreglass batting, you’ll use pre-cut panels or long sheets. Some batting has a vinyl facing that lends a smooth surface that presses against the doors. This can make it slightly easier to work with.

Cellulose fibre

Cellulose fibre is made of recycled papers that are turned into insulation making them a more eco-friendly choice. To make it fire-retardant, it gets treated with chemicals. As it’s a loose fill, you’ll have to place it in a casing or other material.

Rigid foam panels

Right foam panels are made of a polyisocyanurate insulation (PIR) and can be ordered to size or cut into boards. Also, as they don’t have fasteners or seams, cold or heat can’t get through. Compared to fibreglass batting and cellulose fibre, rigid foam panels retain heat better. This means that it will offer better insulation for your garage than the other two types.

A helpful timetable for your insulation project

Garage door insulation has a number of benefits (see below), but many homeowners wonder what they will be getting themselves into. The great news is that, depending on the type of insulation you choose, installation doesn’t have to take forever but the material itself can be long lasting.

Insulating your garage door can be completed within a day. In fact, depending on the panels that you use, you can reduce the time required for the project to only a couple of hours.  For example, with KoolDoor’s kit, it takes between 2-3 hours to install the panels.

Once the insulation is in place, you can expect the panels to last 10 to 20 years. Not only does insulation last long, but it also requires little maintenance. You basically only need to tighten bolts and screws from time to time making it worth the effort. If one of the panels gets damaged, you can simply remove the damaged panel and replace it with a new panel.

The many benefits of insulating your garage door

Garage door insulation is popular across Australia since the temperatures can fluctuate in extremes. In addition to temperature control, this type of home improvement offers many other practical advantages that many homeowners are unaware of.

Noise reduction

Since an insulated garage door is thicker, it can help to reduce external noise like traffic. If you’re more concerned about your own noise levels, you’ll be glad to know that it can help with that, too. This can be a valuable benefit if you use your garage as a workshop or an area for the kids to play. Not only won’t you be bothered as much by external sounds which can be distracting, but the noise that you make will also not bother your neighbours or the rest of the family.

If you don’t have plans to use the space for other activities, it can still help with noise reduction as the operation of your garage door will often be less intrusive.


Insulated garage doors are stronger. This means that the chances they will warp or dent are lower since the insulation actually reinforces them to varying degrees (depending on the type of insulation you choose). What’s more, insulating your garage door also makes it more durable. Not only will they require less maintenance, but you could also find that you don’t need to pay for costly repairs as often.

Vehicle protection

Not only can insulation help to protect the garage door itself, but it can also help to reduce the overall stress on your car. By insulating your garage door, you don’t have to start your car in extreme heat or cold conditions which will help to keep its engine in better shape.

Energy efficiency

If you insulate your garage door, you’ll find that it can help to reduce energy usage throughout your home. Insulated garage doors are better at regulating the temperature which means that you won’t necessarily need to switch on the air con or heater as your garage will be at a consistent temperature.

Increased home value

If you ever decide to sell your house, an insulated garage door will drive up its value, especially if it can be used as an extra space like a workshop or gym. Even if you still use it only purely as a place to park your car and store a few items, potential buyers will be able to save on energy costs, a unique selling proposition that can bump up the asking price.

What are the downsides of insulated garage doors?

When it comes to insulating your garage door, the benefits far outweigh the downsides. In fact, the only downside relates to cost. However, keep in mind that this home improvement will help to reduce your energy spend and increase the value of your home.
