INSULATE YOUR HOT & COLD, NOISY GARAGE INSTANTLY!
The polystyrene panels prevent the passage of air through the floor to outside, and cold air from entering directly through the floor. In addition, their main benefit is as a thermal barrier to prevent the convection/movement of heat energy into and out of the house through the floor. The polystyrene stabilises the internal temperature of your home and saves on energy bills.

DIY GARAGE DOOR INSULATION KITS
WA Polystyrene also offers a custom-cut service, and cut the insulation panels to your required measurements, to drop into the sectional spaces of your garage door (ready to go). Just measure up and give us the dimensions of each section, as per below image, measuring vertically and horizontally each section that is to be installed (orange-filled area). Generally, there would be 8 panels for a standard single garage door and 16 panels for a standard double garage door.
The same goes with the thickness of the panels, we also can custom cut the thickness of the panels. A thickness of 40mm will be a good fit in many cases, though panel thicknesses can range from 32-45mm, so check this dimension too.
These garage door insulation panels, at 40mm thick, have an R1.1 thermal resistance rating. This thermal performance is typically stable over decades after installation. (WA Polystyrene panels are made from firm grade of 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.
Customer Testimonials witness to recorded temperature decreases of 10°C – 15°C and more in the garage on hot summer days, and moderated winter temperatures too.
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.
