WebAnswer (1 of 5): Some conductive materials produce more heat than others, but this is not a measure of “efficiency” (the ratio of output to input). High current flowing through a wire that acts as a resistor will convert electrical energy to heat. Nichrome wire, for example, is commonly used to ... WebWall 1 with U-Value of 0.3 W/m2 K will lose heat at half the rate of Wall 2 which has a U-Value of 0.6 W/m2 K . So, the LOWER the U-Value, the BETTER. The lower the u-value the more efficient the construction is at keeping heat flow through the structure to a minimum. Are U-values important in the Building Regulations Approved Document Part L?
