For designing extensions with over 25% floor area as glazing. U Value. An insulating glass unit comprising 4 mm Pilkington Optifloat™ Clear outer pane, 16 mm argon gas-filled cavity and 4 mm Pilkington K Glass™ S You just calculate R-value from U-value like this: R-Value (U-0. The unit of the U-value is W/m²K (watts per square meter and per Kelvin) and indicates the heat flow through an area of one square meter with a temperature difference of one Kelvin (= 1°C). 2226 Atlanta, Georgia: 718. It helps you to weigh up the best glazing f FREE Lite version: U-value Calculator Spreadsheet to BS EN ISO 6946, 13370, 13789, BRE 443, 497 (1. A detailed description of these values can be found here or in the standard ISO 13786. Water efficiency calculator tool (Excel Spreadsheet, 0. U-values are measured in w/m2K which is the units of watts per square metre per degree Kelvin or in other words the amount of heat loss through a 1 square metre of material for every degree difference in temperature Online U-Value Calculator. 1 Heated basements 27 10. If positive the glass is showing a loss of heat and a negative value the glass is letting in more heat than it is losing. Once a final U-value has been determined, For bespoke calculations and ones not found on our U-value Calculator, please contact our technical department. What users sayWe carry The heat transmission through a building wall or similar construction can be expressed as: H t = U A dt (1). Calculations from the Oracle online U-value calculator are recognised by FENSA and Certass for their competent person schemes. V.

The U-value represents the amount of heat that passes through one square meter (m²) of the element when there is a temperature difference of one degree Celsius (°C) between the interior and exterior Related services Glass optical & thermal properties. 9 U value. 2 (Thermal Resistance of Airspaces), Annex F (Correction to thermal transmittance). The cost of this service is £35 per certificate. Determining the U-Values of the glass and complying with the National Energy Act may be easier than you think. 0W/m2K – which means that for every degree of temperature difference between the outside and the inside, a square metre of the glazing would lose 6 watts. The U-value represents the amount of heat that passes through one square meter (m²) of the element when there is a temperature difference of one degree Celsius (°C) between the interior and exterior Therefore, R-Value multiplied by U-Value always equals 1. This means that the higher the U value the worse the thermal performance of the building envelope. 1–1. It has 30% less weight than triple glazing windows.
