U value or K value ( Watt per hour lost etc) is a measure of how much heat is transfered through a certain material, a pilkington K glass unit as a U value of 1.5, a standard douvle glazed unit is about 2.6, the lower the number the better, a single brick will be poor, a modern house is built with an insulated cavity wall and the u value would be approx 0.25, hope this helps.
A nine inch solid wall would be approx 2.00
