ACCORDING TO SANS 10400-XA & SANS204 THE MINIMAL THERMAL RESISTIVELY VALUE
SLATE TILES AND IBR SHEET AND HORIZONTAL CEILING

TOTAL R -VALUE IS ACOMBINATION OF ROOF ASSEMBLY
R-VALUE OF ROOF &CEILING MATERIALSCALCULATED FOR SLATETILES CEILING BOARDS
MINIMUM VALUE OF ADDEDTHERMAL RESISTIVITY FORREQUIRED INSULATION
CALCULATED AS PER SANA 10252 - 1 : 2004
HOT WATER DEMAND 345lt
STORAGE CAPACITY 700lt
ALL HOT WATER PIPES MUST BE INSULATED WITH THERMAL RESISTIVELY OF AT LEAST 1
THE DESIGN COMPLIES WITH THE REQUIREMENTS OF SANS1050 XA - 2011 & SANS 10252 -1 & 1307 & 10106 & 10254 :2004
HOT WATER CALCULATION
minimum of 50% of the annual average heating requirement for hotwater must be provided by means other than electric resistance heating(Geyser) or fossil fuels• See options below but not only limited to these:• Solar heating• Heat pumps• Geothermal heat• Renewable combustible fuel• Heat recovery from alternative systems and processes

2.8
TO ACHIEVE THE THERMAL RESISTIVITY OF 2.8 ONE OF THE FOLLOWING IS RECOMMENDED:
1. PINK AREOLITE,GLASSWOOL THERMAL & ACOUSTIC CEILING INSULATION WITH A MINIMUM THICKNESS OF 115mm WHICH HAS AN R-VALUE OF 2.8
2. COMBINATION OF PINK AEROLITE & REFLECTIVE FOIL CAN ALSO BE USED PROVIDED THAT THE R-VALUE OF THE COMBINATION IS GREATER THAN 2.6
3.ECO - INSULATION CELLULOSE FIBRE CEILING INSULATION WITH A MINIMUM THICKNESS OF 100mm
NOTE :
ABOVE POINTS IS A RECOMMENDATION ONLY ANY INSULATION CAN BE USED AS LONG AS THE THERMAL RESISTIVITY OF MATERIAL IS MORE THAN 2.8
CONCLUSION
THE DESIGN COMPLIES WITH SANS 10400-XA-2011 IF THE ABOVE CONDITIONS ARE MET
