The insulating properties of Cooldek® Roofing reduce heat from above on hot days, significantly increasing comfort levels under the roof.  Cooldek® Roofing reduces noise from heavy rain and aids in keeping your home cool, reducing energy costs and your carbon footprint.

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.

Choose from either the Cooldek® ribbed or the Cooldek® CGI roofing profiles.  For the underside, there is a choice of smooth or one of two ribbed profile finishes. These are available in white or a choice of high gloss colours.


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