WHAT IS A U-VALUE AND WHAT DOES W/m2K MEAN?
A regular question we are asked is 'What is a U value and what does W/m2K stand for'?Right here we go: A "U Value" is a measurement of how well a building component retains heat inside a building. For the Spanish contingent, this is equally important because the "U Value" is also used to determine how long the inside of a building can be kept cold. In both cases "U Value" is needed to establish the amount of energy required to retain a comfortable interior temperature. So, a "U Value" is a measure of the heat flow through a building element (e.g. Wall) The higher the U value the more heat you are loosing. Therefore the lower the "U Value" the better for us because we want to retain the preferred temperature. How do we measure a "U Value"? Well, this is where our little mate the W/m2K comes into his own!
"U Value" describes how much thermal energy, expressed in WATTS (That's the W) is transported through the building component the size of 1 SQUARE METRE (that's your m2) at a temperature difference if 1 KELVIN (there is the K). The Kelvin is equal to 1 deg C. So, W/(m2K) What do we need to achieve under the English Building Regulations Part L? The law says a min of) 0.27W/m2K must be achieved.
What do we achieve with our 140mm stud system?
Depending on the insulation we use we can get down to almost ZERO emission. We can therefore easily meet and beat minimum requirement, once again demonstrating that we have a very superior 140mm system compared to others, who only use an 89mm external stud. Ours is also an infinitely superior system to Brick/Block construction, as we exceed the target rating and still have a clear cavity for air circulation which Brick & Block do not have, because the cavity is stuffed to the gills with all sorts, to achieve the minimum rating of 0.29 W/m2K We hope this has been of some use to you.
