WebbWall 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?
