The SANS 204 legislation deems certain thicknesses of insulation safe for each climate zone.
|SANS 204 Recommended Aerolite Ceiling Insulation Thicknesses For Your Climate Zone:|
|Minimum required Total R-value (m².K/W) (for roof solar absorptance of more than 0.55)|
|Zone 1 = 135mm – use 135mm Aerolite|
|Zone 2 = 130mm – use 135mm Aerolite|
|Zone 3 = 100mm – use 100mm Aerolite|
|Zone 4 = 135mm – use 135mm Aerolite|
|Zone 5 = 100mm – use 100mm Aerolite|
|Zone 6 = 130mm – use 135mm Aerolite|
The above deemed to satisfy thicknesses are based on the “R” values for the relevant zones.
Aeropink installs 135mm or 100mm Aerolite to meet the recommended R-value
In case of any change requiring plan approval, a rational assessment shall be carried out. The Deemed-to-Satisfy Provisions are based on six climatic zones.
South Africa has become very aware of the importance of healthy homes and conservation of energy as part of the move to sustainable building. Insulation correctly installed plays a large part in ensuring efficient use of energy and a healthy internal environment in South African buildings.
