The availability of the grades in the 2008 version of the standard will not differ substantially from the grades available in the 1995 version of the standard.
COLORBOND® Ultra steel is not the same as it's forerunner, COLORBOND® XSE steel. There are several technical differences between the two products. However, COLORBOND® Ultra steel is designed to fulfill the same role in severe marine and industrial environments as COLORBOND® XSE steel did. Therefore, where you would have previously specified COLORBOND® XSE steel, you can now rely on COLORBOND® Ultra steel to provide the protection you need.
It is a BCA and AS/NZS3000 standard that any new dwelling, regardless of framing materials, must be fitted with a safety switch known as an RCD (Residual Current Device) or an ELCN (Earth Leakage Circuit Breaker). These devices are designed to prevent death by accidental electrocution.
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 strength of the sun.
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.
Steel framed houses have many advantages over other materials; they are termite proof, fire resistant, and a cost effective investment when you consider safety and peace of mind.
