COLORSTEEL colours

CloudThe COLORSTEEL colour that throws back the most sun.

Cloud reflects more of the sun's heat than any other COLORSTEEL colour, with a published TSR of 69% and an LRV of 74%. It's a clean, versatile white that NZ Steel pairs with dark cladding, roofing and joinery, so it can be the bright contrast on a dark house as well as the roof.

What does Cloud look like, and how cool does it run?

NZ Steel describes a clean, versatile white, made in the Classic finish only. In strong sun a Cloud roof looks very white indeed.

TSR measures how much solar heat a colour sends back, so a bigger number means a cooler roof surface. Cloud's 69% sits at one end of the range and Ebony's 5% at the other. Against the other whites the gap is small: TuiTuft and Titania are both 66%, and NZ Steel's figures carry a 5% tolerance either way.

Using Cloud on walls, spouting and trims

If Cloud goes on cladding or accessories rather than the roof, read the warranty table. For MAXAM in a Mild environment, NZ Steel covers roofing for 50 years against perforation, wall cladding for 30, and accessories such as spouting (gutters), downpipes and fascia for 15.

Walls need more care too. NZ Steel asks for wall cladding to be washed by hand every year in Mild and Moderate areas, and more often nearer the sea.

Before you order Cloud

  • A real sample, looked at outdoors. NZ Steel says screens show its colours differently from the product.
  • Your site's COLORSTEEL category, from Mild to Extremely Severe, and whether that means MAXAM or ALTIMATE.
  • Warranty confirmed with COLORSTEEL if the house is within 100 metres of salt water.
  • In geothermal areas such as Rotorua, product and warranty checked with NZ Steel.
  • A written quote naming COLORSTEEL, the product and Cloud, plus a copy of the warranty.

If it were our house

For a roof in full sun where heat is the main worry, Cloud is the colour we'd look at first, provided glare won't bother anyone looking down on it. On a dark modern build, we'd also try it as the trim colour. We're independent and not affiliated with New Zealand Steel.

Questions

Straight answers.

Does a Cloud roof get dirty quickly?
It shows grime sooner than darker colours, especially around flues, aerials and solar panels, which NZ Steel lists as unwashed areas needing hand washing. That's a job for a roofer with proper access, not a ladder.
Cloud or TuiTuft?
On heat there's little in it. Cloud reflects a little more light, so it reads slightly brighter, while TuiTuft is described as crisp. Compare the samples side by side in daylight.
