Garage Door Insulation

Transform your Hot & Cold, Noisy Garage into a Comfortable, Quiet Living & Working Space.

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 of your door sections. 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 for each of your door panels. Please enter all your panel sizes above when placing your order.

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 a result.

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 want to use 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 standard set of double garage door panels (usually 16-20 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 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. 

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

* A set of panels for non-standard height doors up to 3m and beyond will weigh more than 7kg, and will incur an additional cost accordingly.

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

Excellent service

Prompt reply to query. Product easy to install. Installation was much easier by using rubber gloves (to move the insulation foam in the garage panel).

Excellent Product and Service

Garage Door Insulation arrived earlier than quoted, was sized perfectly, and does exactly as advertised. The garage temperatures in summer have been radically reduced!

Thanks for your kind words Marc. Your positive feedback means alot to us. We are so thrilled to hear your great experience with us. JM

issues

I purchased 12 panels for a taller single door. got told I had to pay nearly 50% more due to the extra panels. talked down to cost price for the extras.
ordered turned up with 2 panels short of whole order and all panels 5-10mm smaller than asked for.
ended up just getting a refund and having to bin all the panels supplied at my cost.

Hi James, thank you for taking the time to review. We sincerely apologise for your poor experience with us this time. We appreciate your feedback as it helps us to iron out the issues that do occur from time to time.

From a personal point of view James we are sorry for your experience, but also disappointed. We have now supplied you with insulation panels for a 3m high double door at 2m high price. Then this 3m high single door insulation also at discounted price. If the panels were 5-10mm smaller than ordered (in both sizes!!) then it is not clear to us why you would not fit them to your door in any case? There is surely no need to throw them out? Nevertheless we did not argue but gave you a full refund! None of this, in any respect, looks to us like one star service.
