The garage door insulation Australia actually needs.

We are based in Jamisontown NSW (ABN 33 137 871 277).

Why we built it

A bare metal garage door bakes in the sun all day. Heat pours straight into the room. By late afternoon, most Australian garages are unbearable.

The obvious fix, a new insulated door, costs thousands and takes weeks. Most people just leave the garage and give up on the space.

KoolDoor is the other option. You keep your existing door and line it from the inside. The panels clip in. No builder, no major expense, no drama.

What we make

Our panels are closed-cell PIR foam, matte white on both sides. The material carries an R1.5 rating, which is the measure of how hard it works to slow heat transfer. Cut panels to fit your door sections, press them in, and the door goes from the hottest surface in the room to a proper insulated barrier.

The result: a garage that stays up to 20°C cooler. A room you can use as a gym, workshop, home office or anything else. Year-round.

We also make garage door seals, which block the draughts, dust and pests that sneak in around the edges.

How we are different

Most companies in this category give you a vague “degrees cooler” claim and keep their pricing off the website.

We do not do that.

Every KoolDoor page shows the R-value (R1.5), the temperature claim (up to 20°C), and the full price list. You know what you are getting and what you will pay before you commit to anything.

A few other things that matter:

Backed for 10 years. Every insulation kit carries our 10-year guarantee against manufacturing defects.

Two ways to buy. DIY kits ship anywhere in Australia. Professional install is available in Sydney, Melbourne, Brisbane, Hobart and Adelaide. Most companies offer one or the other.

10-year guarantee. Every insulation kit is backed by a 10-year guarantee against manufacturing defects. That is a reasonable length of time to expect a product to hold up in Australian conditions.

Real pricing, published openly. A Standard Single kit is $370. A Standard Double is $700. An Extra Large Double is $880. All prices include GST. Delivery is calculated at checkout based on your location. No surprises at the end.

Who it suits

KoolDoor works well for homeowners who want to get more use out of their garage without building an extension or replacing a perfectly good door.

The DIY kit is honest about what it takes: a tape measure, a straightedge and a knife. Most people have the whole thing done in about 2 to 3 hours. No glues, no chemicals, no builder.

If you would rather not do it yourself, our install team covers five capital cities. We measure, cut and fit it in one visit.

It is not for everyone. If your garage door is in poor condition or an unusual shape, it is worth calling us first to check. We are reachable on 1300 37 38 39 or at sales@kooldoor.com.au.

Our guarantee

Every kit comes with a 10-year guarantee. If the panels fail to perform under normal use, we make it right.
