South Africa's Climatic Zones

According to the new SANS 204 and SANS 10400 XA, South Africa has been divided into 6 climatic zones. The ceiling insulation thickness (R-Value) for each region is dependent on certain climatic conditions and recommended as  "deemed to satisfy".

All insulation materials are rated for their performance in restricting heat transfer. This is expressed as the “R-Value”, which is the measure of the material’s resistance to heat transfer, alternatively known as thermal resistance. The higher the R-Value the greater the insulation effect. It is the reciprocal of thermal conductance/transmittance.
