What are the benefits of Stratco Cooldek Roofing?


Outstanding Climate Control

Let’s be real – Melbourne weather can be pretty fickle, and changes frequently… sometimes multiple times in one day!

A Stratco Cooldek Insulated Roof allows you to enjoy your outdoor space year-round with the benefit of controlling your own climate. It’s kind of like your own personal force field to protect you against extreme heat in the summer or chilly weather in the winter.

And the best part? If your patio is attached to or right next to your house, the Cooldek roofing will also keep the main house cool and comfortable too!

Energy Saving

Say goodbye to your ceiling fans and portable heaters – you won’t be needing them anymore. That’s the beauty of Stratco insulated roofing. As our Cooldek roofing is specially designed to control extreme temperatures, having it installed into your existing or new patio will do wonders for your electricity bill.

Sleek and Smooth

Stratco Cooldek Roofing just looks good. It’s sleek and uncluttered, especially because it conceals ceiling lights and any electrical wiring. You’ll never feel more at home than underneath your Cooldek patio.


What colour are you feeling? A classic crisp white? Or something a little funkier that matches your existing colour scheme? Stratco has a wide range of beautiful, high-gloss colours.

You also have your choice of insulation thickness to match the climate you’re in.

Strong and Sturdy

Cooldek Roofing is exceptionally strong and versatile, and can last a lifetime. Because of its impressive strength, Cooldek can span up to 7.2 metres, with fewer supporting beams and framework required, meaning a much sleeker appearance.

It has been designed, engineered, and rigorously tested to comply with relevant Australian standards.

Increases Your Property Value

More and more home buyers are on the hunt for a property that has a great place for outdoor entertaining, or simply another area to chill out and enjoy the great outdoors. Having an outdoor patio is one thing, but having an insulated patio adds that extra layer of comfort that is appealing to potential buyers – something to keep in mind if you ever plan on selling in the future.

Reduces Noise

Cooldek insulated roofing can do wonders for reducing noise. Because of the porous nature of insulation materials, sounds are absorbed – meaning if you have noisy neighbours, bustling street noise, or a load of loud weather, your insulated Cooldek patio roof will keep the racket on the down-low.

Full Lifetime Warranty

With a 25-year lifetime warranty, you can have peace of mind that your Cooldek roofing will stand the test of time.

Insulated Advantage

For cooling comfort

Cooldek roofing features a polystyrene core that is permanently bonded to a smooth, easy to clean coloured steel underside and a profiled, coloured steel topside. The insulating properties of Stratco Cooldek roofing reduce heat from above on hot days which significantly increases comfort levels under the roof. It also reduces noise from heavy rain and will aid in keeping the interior of your home cool, reducing your energy costs and your carbon footprint.

Year Round Use

You can include lighting, fans or heaters to compliment your wonderful Outback® living space. With the wide range of accessories available, you can enjoy your Outback® lifestyle all year round.

Design Considerations

The minimum recommended roof pitch for ‘flat’ verandahs shall be 1° (1 in 60) for Cooldek Classic panels and 3° (1 in 20) for Cooldek CGI panels. The maximum roof pitch for ‘flat’ verandahs shall be 5° (1 in 12). Care must be taken to ensure the minimum roof pitch is maintained to avoid ponding of rainwater.

The roof is designed to withstand maintenance activitie, roofs are not to be used for floor type activities.

The design contained within these span tables relate to wind classifications N1, N2, N3, and N4 applicable to Regions A and B. Stratco does not accept liability for any loss or damage suffered as a result of any errors in the interpretation or application of these span tables.

The Wind Capacity Tables are based on testing in accordance with AS1562.1-1992 and AS4040.0, 1 & 2-1992. Span tables have been developed by determining wind pressures in accordance with AS4055-2006 for domestic applications. Capacity tables are in limit state format.


The spans given in the ‘Single Spans’ table are determined for wind speeds for non-cyclonic areas. Indicated spans are suitable for ‘flat’ roof patios. Open freestanding unit spans can be taken from open three sides unless a wall, eaves or boundary exists within 500mm of two or more sides.

For Cooldek roofing in attached or freestanding domestic gable patio application, sheet spans shall not exceed those given for one or no open sides. Alternatively the ‘Wind Capacities’ table may be used to determine allowable single spans for any application.

Spans specified for units with three sides open are suitable for units considered ’empty under’ and not exceeding three metres in height (from ground or deck level). For units in which goods or materials stored under the roof are expected to block greater than 50% of any open side exposed to the wind, take the spans from open two sides.

For units with two open sides, spans are based on Cp,n=-1.0 while for units with only one or no open sides, Cp,n=-1.2. In all cases, relevant consideration has been given to local pressure.

, Cooldek Service

Note: The ‘Wind Capacities’ table provides allowable wind capacities for Cooldek in single span application for serviceability and strength limit states. The pressures given may be used by a suitably qualified engineer for any single span application ensuring appropriate fixing details are applied.
