What is a U-Value? A U-Value is the rating of energy efficiency of your double glazed unit. Free Pilkington Spectrum U-Value Software Click here to Download . 8 w/m2K. The U-value of a window is a measurement of the rate of heat loss indicating how well your windows are keeping valuable heat in. As Clear as regular clear float glass with the same high Clarity and high Visible Light Transmittance (VLT) that maximises natural light entering inside and filling your space. This calculator is based upon EN ISO 14438:2002, ‘Glass in building. Double glazing with low emissivity glass (with argon gas cavity) U value = 1. U Value. 63 1. The lower the U-value the better the thermal performance of the glass. It is expressed as Watts per square metre Kelvin W/m2 K. The importance of U-values depends on the outdoor temperature difference. Quick Summary:At a quick glance - the U-value is the measure of how well a material resists heat 8 U Value – measurement unit is watts per m2 per degree celcius (W/m2ºC) and is a measure of the rate of heat gain or loss through glazing due to environmental differences between outdoor and indoor air. For doors which are half-glazed the U-value of the door is the average of the appropriate window U-value and that of the non-glazed part of the door (e. U-values explained The lower the U-value, the better the thermal performance Thermal performance is judged by the heat loss through a substance – in our industry this is the glass and window frame as a combined product. This To calculate R-value, divide 1 by the U-value figure. If you are not sure, U value, in simple terms, is the measurement of heat loss in a glass and the rate at which the heat is lost. The spandrel color does not impact U-Value. ” Single Glazed 6mm Clear IGU 4mm Clr/10mm Air/4mm Clr U or Uw Value SHGC/w U or Uw Value SHGC/w Glass ONLY 5.
