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 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. Our Polystyrene Garage Door Insulation reflects these 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 a double garage 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 30-45mm, 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. (Please commonise dimensions that are +/- 2mm.) 

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 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 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 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 thermal resistance of the polystyrene panels. 

Customer Testimonials witness to recorded temperature decreases of 10°C and more in the garage on hot summer days, and moderated winter temperatures too. Check the Customer Reviews here below or a Selection of Testimonials.

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. (Do not use solvent-based adhesives, or oil-based paints on these panels.)

A standard set of double garage door panels (usually 16 panels)* will weigh 7kg on average. On doors with balanced spring tension this is not enough weight to affect your motor or 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 and quantities of each in the comments box above when placing your online order.

* A set of panels for non-standard height doors up to 3m and beyond (20-30 panels) 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 delivered within WA.
