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 are also improved by the sound absorbing characteristics of the polystyrene panels that 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. (See Customer Reviews below)

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 in the box provided when placing your order. (Please commonise sizes to a maximum of 4 unique sizes per Double Door Kit. Should you have more than 4 panel sizes, trimming of panels is easily done with a utility knife.)

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 purchase polystyrene panels of  40mm thickness, these will have a Product R1.1 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 Kits. 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.

Great product.

Already quieter. Warmer these cold days but I expect the greatest benefit next summer.

Thanks for your Review Nick. We also expect the benefit for you next summer will be similar to the experience of those who have reviewed on this in previous seasons. SB

Patrick L. (Sydney, AU)
A game changer!

Got the shipment over in no time, and it took even less to setup. Needless to say it made a huge difference, so can’t wait to see the panels in action during next summer heat. A no-brainer if you’re thinking of turning your garage into something more than a storage place.

We agree Patrick, a no brainer! Glad you had such an easy experience with set up. Thanks for your review. RB

Allan J. (Melbourne, AU)
Great product

Took longer to get out of the packaging than it did to install..Fantastic. Would reccomend it to anybody.

Everyone loves a quick assembly! Thanks for the recommendation Allan. RB

Steve W. (Adelaide, AU)
Excellent Service and Product

More than just a little impressed. Followed the video for measurement and fitting. No problems what so ever, panels do give a little if there is a bracket slightly in the way. I fitted the panels for acoustic reasons and has worked perfected with the added advantage it’s warmer in the garage and my heater doesn’t have to work as hard.
Well done guys very impressed!!

A wonderful result Steve. The video is a helpful guide and you're right, it should be very straightforward from there. RB

Nagambie Project

Panels arrived cut to correct size and were easy to install -- some edges were damaged in transit but managed to jam them in so they are not very noticable -- would suggest cardboard angle
strip be added prior to wrapping to avoid this in future. Garage now holds +/- 2 deg of main house [ I added bats to ceiling as well ] Very pleased with result

Hello Mitch, thanks for your feedback. Your packaging suggestion also is appreciated. We expect that you will get an even better result in heat reduction on hot summer days. SB
