* The value of the bulk insulation to be added to the typical R value. A typical R value fo bulk insulation of 50mm would be R1.0-1.2 and may vary depending on the product selected
** Different levels of thermal performance can be achieved, based on summer or winter climatic conditions and the use of reflective foils. The minimum value (or winter condition) is the one that in general needs to meet the minimum BCA level of performance and is the value given here

* All Durisol walls plastered inside and outside

Durisol offers a number of different levels of intergrated insulation with our SINGLE LEAVE, CAVERTY FREE Wall construction. Test conducted have varified that Durisol Walls do not suffer losses in R-value after construction due to the fact that a Dusriol Wall is a complete, sealed unit with no thermal bridging. See the following link for details: Durisol Thermal Performance. Please note, that R-values and codes listed in this link are based on US Standards using "Degrees Fahrenheit" and "Square Feet", whilste Australia uses "Degrees Celsius" and "Square Meters" as reference values. To convert listed R-values to Australian Standards, divide shown R-values by 5.75.
