Cooling energy savings will vary considerably as each building is unique in its construction and operation. Factors that will influence potential savings can include building shape, building function, the amount, quality and installation of roof insulatio...

Total Solar Reflectance (TSR) is a measure of the ability of a surface to reflect the sun’s energy. Any energy that is not reflected is absorbed by the surface causing it to heat up.

Green Star™ is a voluntary rating system developed to evaluate the environmental design, efficiency and performance of Australian buildings. The system is not used to evaluate individual building materials or products. For more information, view o...

The Total Solar Reflectance (TSR) will drop for any light coloured surface if it becomes dirty. How much it drops depends on what is making the roof dirty. Fortunately all COLORBOND® steel products have excellent resistance to dirt reten...

BlueScope Steel's research team use a spectrophotometer in accordance with the American Society for Testing and Materials ASTM E903-96, which is amongst the most accurate methods for determining solar reflectance. Independent c...

Yes. COLORBOND® Coolmax® steel contains Thermatech® solar reflectance technology which is the same technology that is used in the standard 20 COLORBOND® steel colours.

COLORBOND® Coolmax® steel roofing has equivalent corrosion and paint durability performance to COLORBOND® steel, as reflected by the equivalent warranty offer. However, COLORBOND® Coolmax® steel has greater solar reflectance than COLOR...

COLORBOND® steel does not have a Fire Rating. Information about the Early Fire Hazard ratings for COLORBOND® steel can be found in its Product Datasheet. Download COLORBOND® steel Datasheet (207 kb) Download COLORBOND® Ultra steel Datas...

Temperature variations can cause pierce fixed metal roof sheeting to expand and contract, sometimes resulting in roof noise. This is more likely during rapid changes in the temperature caused by such things as heat from the morning sun, afternoon cooling,...

Adding more insulation is quite different from using COLORBOND® Coolmax® steel, which functions purely to stop heat getting in by keeping the roof cool. Insulation helps stop heat getting in and out of a roof. For a building that is mainly o...

Condensation forms under/on roof sheeting when the sheeting becomes colder than the air in contact with it. Water vapour carried in the air then condenses on the colder surface of the roof sheet. To minimise the risk of water damage to ceilings or corrosi...

The reality is energy costs are going up, not down. That's a concern for most commercial and industrial building owners and tenants. So it's reassuring to know that a roof made from COLORBOND® Coolmax® steel in Whitehaven™ can help red...

Yes. Thermatech® technology that is incorporated into COLORBOND® Coolmax® steel roofing performs in the same way and offers the same product benefits.

The Total Solar Reflectance (TSR) value for COLORBOND® Coolmax® steel in the colour Whitehaven® is 77%.

Sec J requires you to verify the energy efficiency of the building from a heating and cooling perspective. This is typically done in one of two ways: Comply with a series of Deemed to Satisfy (DTS) requirements such as putting a certain amount of...

Using COLORBOND® Coolmax® steel not only results in cost savings from reduced ongoing operational costs but also has the potential to reduce up-front expenditure on HVAC cooling equipment. For an understanding of the possible savings for you...

No. An R-Value is a term describing a material or system that provides a consistent level of resistance to heat flow. COLORBOND® Coolmax® steel roofing provides a varying level of resistance to heat flow into a building depending on the stre...

Currently COLORBOND® Coolmax® steel meets the highest level of concession available under the Deemed to Satisfy provisions of the BCA. Alternatively, the higher TSR value may be used within energy assessment software to improve performance, reduce...

For a cool roofing product to perform best in hot sunny conditions it needs to have a high Total Solar Reflectance (TSR) and a high thermal emittance. COLORBOND® Coolmax® steel has both. It is cooler than ZINCALUME® steel and the rest of the C...

Thermatech® technology in COLORBOND® steel is used to enhance the Total Solar Reflectance (TSR) of homes as well as commercial buildings. COLORBOND® Coolmax® steel in Whitehaven™ has the highest TSR in our product range, and has been...

The cooling energy savings associated with COLORBOND® Coolmax® steel have been quantified in our own BlueScope Steel building study. This involved comparing the relative running costs of three identical insulated buildings, the only differen...

The solar absorption value of COLORBOND® Coolmax® steel in Whitehaven™ is 0.23. To see the comparative values and BCA ratings of the complete COLORBOND® steel range, check our colour classification guide....

Post-applied solutions may initially have a higher Total Solar Reflectance (TSR) value, however studies suggest that the solar reflectance of COLORBOND® Coolmax® steel may be greater in a very short period of time due to its excellent mainte...

Years of extensive testing have been completed to ensure COLORBOND® Coolmax® steel maintains all of the quality and durability benefits of COLORBOND® steel. This includes the assessment of physical properties, accelerated corrosion and outdoor...

The position of most commercial and industrial roofs mitigates the likelihood of roof glare because they are often high-set with a low pitch so they are rarely seen from the ground and the surface has very little impact. Roof glare complaints are commonly...

The Total Solar Reflectance (TSR) value of COLORBOND® Coolmax® steel in Whitehaven™ is greater than COLORBOND® steel in standard colours by between 9% and 52% depending on the selected colour.

The product will perform similarly to COLORBOND® steel in Surfmist® and can therefore be used in any application where that product has been considered suitable. Both COLORBOND® Coolmax® steel in Whitehaven™ and COLORBOND® st...

In most Australian climate zones, the cooling energy saved usually more than offsets any additional heating energy, particularly for buildings that are predominantly cooled during the daytime, such as commercial buildings. In winter the sun is lower...

COLORBOND® Coolmax® steel helps reduce the surface temperature of a roof, which can translate to a cooler room temperature. A BlueScope Steel building study found that the insulated building with COLORBOND® Coolmax® steel in Whitehaven®...

It is recommended that ZINCALUME® steel not be heated above 200°C. GALVALUME® steel (Zn-Al alloy coated, resin free) should not be heated above 350°C. It is recommended that zinc coatings not be heated above 250°C. COLORBOND® st...

COLORBOND® steel incorporating Thermatech® technology provides a new level of thermal protection for houses & commercial buildings constructed in Australia. This leading edge technology works by absorbing less heat from the sun and therefore p...

The Building Code of Australia (BCA) has classified roof colour into light and dark on the basis of their solar absorptance. The lighter complying colours qualify for a Deemed to Satisfy insulation concession. The New South Wales Building and Sustainabili...

Using thermally efficient roofing materials like COLORBOND® steel can help reduce your cooling costs. In summer, a lightweight insulated roof made from COLORBOND® steel can assist in minimising the amount of heat radiated into your home at night. ...

No. The fence will not burn or act as a fire source, although the paint finish may be damaged. In fact, new research conducted by the CSIRO and the Bushfire CRC shows steel fences can assist in the protection of your home in the event of a bushfire. To f...

Steel panels do get warm in hot weather but the fence panels are vertical and air circulates around them. However, BlueScope Steel does not recommend using the fence as a trellis.
