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.

Good product at good price

Reasonably easy to fit I had to cut some (a good bread knife was just the thing), that was after measuring several times one tip is to measure every one separately. Some of the panels had bumps that could not be seen. You obviously have to slide them in so save some bits for packing. Very pleased with the end result the door is quieter and doesn't rattle and the garage is cooler. One tip is if you are using the product to quieten the door down think about new wheels. And watch the videos of how to install both items and keep in mind it's not hard to do but the videos make it look easier than in reality

Fit like a gloves!

Very easy to install and it fits perfectly on my garage door like a gloves. It helped reduce the noise going outside and now I can even do my work at night without disturbing the neighbours.

We appreciate receiving your Review Jay. We are really pleased that this product is working so well for you. SB

Foaming great

The foam insulation supplied was ready for collection in no time and was cut perfectly to my measurements.
It has made a huge difference knocking the heat down that turned the garage into an oven, is now cool as 🙂 👍.

Hi Dean, Good news to hear of the big improvement in your garage temperature. Thank you for letting us know. SB

Shaun F. (Sydney, AU)
Worked better then I thought it would

Was able to reduce the decibel level by 20 from the outside, this allows me to work in my garage without the neighbors complaining. The only thing I would point out is to look out for any little clips that will get in the way of sliding the foam panels in and cut little sections in the panel to allow the foam to slide past because once you get these things in you won’t be able to get them out

Very helpful feedback Shaun. Thank you. SB

K.D. (Sydney, AU)
Good but stinky!

Finally installed after getting my measurements wrong and needing to cut (messy). Happy with end result but what is the smell/off gas? Will it go away? It is very strong. I hope to convert the garage into a studio and can’t wait to be in a cooler/warmer space. Thanks for great phone service.

Hello Kerrian, Thanks for your feedback. As you have been cutting into new polystyrene material, it is usual for some of the gases released as a result, to give off a smell. As the gas supply depletes from the cut surface, so does the smell - the vast majority within a couple of days. Leave the garage door open for an hour each day and all should be well by the weekend Kerrian. SB
