According to Indian Standards, overall thermal transmittance of a wall

1.	According to Indian Standards, overall thermal transmittance of a wall should not be more than __________ kcal/m^2 h deg C.(a) 1.3(b) 2.2(c) 3.7(d) 4.6This question was posed to me by my college professor while I was bunking the class.My question comes from Thermal Insulation topic in section Air Conditioning, Thermal Insulation, Stones & Ferrous Metals of Construction & Building Materials
Answer» Correct option is (b) 2.2 To explain I WOULD say: According to Indian STANDARDS, overall thermal transmittance of a WALL should not be more than 2.2 kcal/m^2 h deg C. Heat insulation of EXPOSED walls can be ACHIEVED by increasing the thickness of the wall.
