The topside colour choices include a wide range of colours to integrate your carport, pergola, verandah or patio into existing colour schemes.

There are three insulation thicknesses to choose from:

• 50mm thick panels with an insulation rating (R value) of up to 1.6
• 75mm thick panels with an insulation rating of up to 2.2
• 100mm panels with an insulation rating of up to 2.8

Strong, sleek and easy to install

Exceptional strength allows Stratco Cooldek Roofing to span up to an impressive 7 metres.

Large spans reduce the number of beams and framework, creating an uncluttered, ceiling-like appearance.

Simple to install, Stratco Cooldek roofing has an inbuilt rebate to conceal electrical wiring for fans and light fittings.

Design Considerations

The minimum recommended roof pitch for “flat” verandahs shall be 2° (1 in 30) 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 actions incidental to maintenance, 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.

Compliance

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 AS4055-2012 for domestic applications. Capacity tables are in limit state format.

Spans

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 spans are to be taken 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.

Walking on Cooldek

When walking on Cooldek roofing, it is recommended you walk over the support beam to avoid damage. Wear flat, rubber soled shoes and walk flat footed in the sheet pans for Classic, and with your weight spread over as many crests as possible for CGI. For carport and verandah applications, away from supports, crawl boards should be used to avoid damage during installation and maintenance.

Maintenance

The performance of Cooldek over time depends on its correct application and maintenance. Maintenance should be performed as often as is required to remove dirt, salt and pollutants. Where used in severely corrosive environments, cleaning should be performed more often. It is important that screws have the same life expectancy as the cladding you have specified. Packs of Cooldek should always be kept dry and stored above ground level while on site. If the sheets have become wet, they should be separated, wiped and placed in the open to dry.
