Garage Door Insulation Kit (Custom Cut)

Transform your Hot & ColdNoisy Garage into a Comfortable, Quiet, Living & Working Space

Foam Sales' Garage Door Insulation Kits are custom cut to your door panel sizes. See Dave's video below on how to measure, and fit your new door panels.

Enter the custom panel sizes you require into the text box provided above. Please allow lead time of 3 weeks for cutting and delivery.

Thermal Insulation using Foam Sales' polystyrene insulation panels on the inside of sectional garage doors makes a considerable difference (up to 10°C - see Customer Reviews below) to moderating the summer heat and winter cold in your garage. During the Australian summer months in particular, metal garage doors  radiate large amounts of heat, often making garage areas impractical for use as a workshop, exercise, or living area, or even for storage of precious items. Our Polystyrene Garage Door Insulation Kit blocks this radiating heat, making the inside environment more temperate, enabling one more usable living space in your home.

Acoustics inside the garage area are also improved by the sound absorbing characteristics of the polystyrene panels that will moderate reverberation and harshness of sound caused by the hard surfaces typical in most garages. This can be good, both for those living inside the house, and for the neighbours too! Door and motor operation will sound quieter as well.

In addition to improved comfort, the more moderate temperatures inside an insulated garage result in less condensation - so less damp and mould, and reduced rusting of the mechanisms caused during periods / nights of extreme cold and wet weather. Most homeowners are likely to experience lower ongoing energy costs as a result.

Garage Door panel sizes do vary considerably, so be sure to take accurate measurements on the size of each of your door sections.  We will custom-cut to the width, height and thickness you require for each of your door panels. Enter all your panel sizes above when placing your order. (Please commonise dimensions that are +/- 2mm.)

When fitting the panels, slide the polystyrene boards into / behind the top and bottom flanges. See Dave's Video on how to measure and fit your new panels. The horizontal stabilising bars may need to be removed in order to insert the panels. Otherwise no tools are required for fitting of the panels, which is usually done in less than one hour. (A pair of cotton or rubber gloves can assist with handling and fitting of the panels.)

The firm polystyrene surface finish on the garage door panels does not need to be covered, and many customers appreciate the benefit of the extra light that is reflected from the white panels. The panels can be painted with water based paints and varnishes if preferred. (Take care - oils, and some silicone sprays will eat into the panels).

For an example of thermal rating, if you were to use polystyrene panels 40mm thick, they will have an R1.1 thermal resistance rating. The Panels are made from firm M grade polystyrene with thermal conductivity of 0.035W/m.°K. The door system value with the panels fitted has a higher R value due to the characteristic of the steel door panels to radiate heat and cold (emissivity) - in this case forced to radiate outside due to the high thermal resistance of the polystyrene panels. This thermal performance is typically stable over decades after installation. Foam Sales' Garage Door Insulation Panels have a 10 Year Warranty.

Adhesive is not normally required for fixing the panels, but if you do want to use it we recommend a flexible long-life MS Polymer such as Soudal T-Rex or Rite Power-X. These products can also be used to fill and seal gaps at the edges. (Do not use solvent-based adhesives, or oil-based products on these panels.)

Prices on this page apply to standard size Single and Double Garage Door. A standard set of Double garage door panels (usually 16-20 panels)* will weigh 7kg on average. On doors with balanced spring tension this usually is not enough weight to affect your motor or door operation, or to require adjustments to spring tension

* A set of panels for oversize garage doors if weighing more than 10kg, will incur an additional cost accordingly.

All polystyrene sheet made in Australia, including these panels, contains fire retardant. The effect of this additive is that in the case of exposure to small flame sources the panels will self-extinguish when the flame source is removed. See test results and flammability comparisons with other building products. 

Customer Testimonials witness to recorded temperature decreases of 10°C and more in their garage on hot summer days, and moderated winter temperatures, with improved acoustics too. Check our Customer Reviews here below.

Simon M. (Melbourne, AU)

The garage insulation kit was cut to perfect size and made installing a dream.
The insulation works really well.
Super impressed.

That is all good news Simon. Thank you for your feedback. SB

Anthony W. (Sydney, AU)
More than I hoped for !

I installed the double garage insulation kit on my west facing garage door and the change in temperature in my garage is remarkable. We decided to use the money we'd saved on gym fees during lockdowns in Sydney to turn our garage into a gym. Only issue was that it was just too hot after noon when it got hot outside. I thought the foam insulation would help a bit but assumed we'd eventually have to install an air conditioner. We've had some hot days already this spring and it is amazing how much cooler it is even in late afternoon. The kit arrived quickly, installation was a breeze and with a decent floor fan I'm now sure our garage/gym will be comfortable to use all year round without having to cough up for an air conditioner.
Can not complain about any part of the whole experience. Thank You!!

Thank you for your detailed Review Anthony. We do appreciate your feedback. We are pleased to hear of the positive results, though like other, not surprised. Wishing you a cool summer Anthony. SB

We appreciate your Review. Thank you Gary. SB

Lyndell C. (Dolans Bay, AU)
Too hard.

It is a great concept but very difficult to install. Make sure don’t measure the depth much shorter than you need. Could not budge them. Now using glue.

Hello Lyndell, we are sorry to hear that you had difficulty installing your new panels. If the panels were difficult to slide into place it is likely that they are a little thicker than the gap between the door front and the flange they are fitting behind? We hope they were cut to the size you ordered? Please let us know if not.
If you are still working on fitting the panels then they can be rubbed back with sand paper along the edges to reduce the thickness by 1 or 2mm along the area behind the flanges. Hope this may help Lyndell. SB

Antonio D.S. (Altona, AU)

Thank you, very easy to order, delivered in a timely manner, very good product, exactly what I ordered.

Thank you for your Review Antonio. Enjoy a cool summer! SB
