Garage Door Insulation

Additional to roof insulation, polystyrene insulation backed onto your garage door can make a considerable difference to moderating the the summer heat and winter cold in your garage. During the Australian summer months in particular, metal garage doors can radiate large amounts of heat, making your garage area impractical for use as a workshop, exercise, or living area. Garage Door Insulation reflects extreme temperatures, making the inside environment more temperate in what is often the least well insulated room in the average Australian home. 

Foam Sales recommends our system of polystyrene panels, which we custom cut to drop into the sectional spaces of your garage door. Just measure up and give us the dimensions of each section. Generally, there will be 4 door sections, each with 4 panels making up the width of the door.

Garage Door panel sizes do vary considerably, so be sure to to take accurate measurements on the size of each section. A thickness of 40mm will be a good fit in many cases, though panel thicknesses can range from 35-45mm, so check this dimension too. We will custom cut to the width, height and thickness you require.

When fitting the panels, slide the polystyrene boards into / behind the existing flanges, or behind the bars on the back of standard panelled garage doors. See Dave's Video on how to take correct measurements and to fit your new panels. No tools are required for fitting of the panels, which is usually done inside half an hour.

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 paint if preferred. 

These polystyrene panels, at 40mm thick, have an R1.1 thermal resistance rating. This thermal performance is typically stable over decades after installation. (Foam Sales panels are made from firm M grade polystyrene with thermal conductivity of 0.035W/m.°K.) The door system value will be higher than R1.1 due to the characteristic of the steel door panels to radiate heat and cold - in this case forced to radiate outside due to the thermal resistance of the polystyrene panels. 

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 well.

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.

Adhesive is not normally required for fixing the panels, but if you do need it we recommend a flexible long-life MS Polymer such as Soudal T-Rex or Rite Power-X adhesive to fix your polystyrene insulation to the garage door.

A set of double garage door panels will weigh around 7kg on average. This is not enough to affect door operation or to require adjustments to spring tension.

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

Remember to enter your panel sizes in the comments box above when placing your online order.

Please allow 3 weeks lead time for Eastern States orders, and 2 weeks for orders within WA.

Great idea and product

Great product. Super easy to install.

Cut to size in all three dimensions accurately.

Look sharp and clean.

Quoted more than 6 x the price i paid to have it done locally.

Excellent finished result

Our garage panel doors radiated a lot of heat into our garage, even though they are a light cream colour. The door exposure to direct sun light is for a long duration of the day, hence, a lot of heat transferred into the garage. Since fitting the polystyrene panels to our garage doors, the heat transfer through the doors has been drastically reduced.
Tip:- When fitting the polystyrene panels to the doors (Held in place by over sizing the thickness of the polystyrene by 2mm compared to door panel thickness method) Place the polystyrene panel in the bottom channel of the door panel, make a mark on the polystyrene panel where the top of the door bottom channel is located, then hand tap the polystyrene up into the top channel of the door panel, this will allow you to see how far you have moved the polystyrene panel into the top channel of the door panel.
The only problem we experienced with our transaction was the delivery time, having said that, I feel the problem was with the delivery agent not foam sales and it was during the Christmas break.

Hi Gordon, Thank you for the review. We're very pleased you're happy with the result that our garage door panels have produced for you. As mentioned, we certainly did have a problem with the delivery with Toll and we do thank you for your understanding regarding the issues there.

Fit great, look great, fast delivery. I couldn't really ask for anything more.

Garage Door Insulation

I ordered garage door insulation on-line. They were cut perfectly to sizes specified and fitted into garage door panels, although a tight fit I managed to get them in. I noticed the difference in temperature in our garage especially in the morning as it faces east and gets direct sun. It also helps with the acoustics from the road. We are pleased with the results.

Thanks for your Review Stuart. We are pleased to hear about the added benefit of the road noise being reduced as well. Foam Sales
