It is 1Higher R-values mean greater insulating power. Single-glazed glass doors might have an R-value as low as R-1, while double or triple-glazed doors with low-E coatings and inert gas fillings, such as argon or krypton, can reach R-values up to R-3 or higher. So we take our R-Value of 21 and divide one by that number, and we get a U-Value of . 0476. 25. This heat loss which is the thermal conductivity of the glass and window products, is known as the U-value. 1 Argon and Krypton figures are based on a standard 90% and 92% fill respectively For multi cavity and other low-E combinations please contact Customer Service on 01207 288200 www. Total Unit Factors determined per NFRC-100 (National Fenestration Rating Council). 081 NR R-13. 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 Thermal transmittance, called U-value, is the amount of thermal energy, measured in W (Watts) flowing through one m² (square meter) of a building component like a window, door, wall, or other part of the building structure if the temperature difference between both sides of the component amounts to 1 K (Kelvin), The unit of measurement is W/m²K. 3. ) Uncoated glass is assumed to have a normal emissivity of 0. 4 %âãÏÓ 2265 0 obj > endobj xref 2265 31 0000000016 00000 n 0000002149 00000 n 0000002496 00000 n 0000002643 00000 n 0000003095 00000 n 0000004072 00000 n 0000004123 00000 n 0000004162 00000 n 0000010342 00000 n 0000010947 00000 n 0000011348 00000 n 0000011784 00000 n 0000011863 00000 n 0000012455 00000 n The Center-of-glass U-value is a measurement of ONLY one location on the glass. 33. 64 0. Shading Coefficient (SC): A measurement of the heat gain through the glass compared to a single lite of clear 1/8" glass. The u-values for spandrel glazing are the same as the corresponding vision unit. Using the U-Factor data, the R-Value can be determined. 5 87 8 8 71 7 <1 5. What is a U Value? U Value is A measure of air-to-air heat transmittance (loss or gain) due to thermal conductance and the difference in indoor and outdoor temperatures. Specifically engineered for use on the interior surface of an IGU, Sungate ThermL™ low-e coating is designed to retain indoor temperatures by slowing down Each pane of glass is typically 0. 30 The lower the U-Factor, the greater the insulation value. In many cases, you will have to convert the U-value or U-factor to R-value. Viracon's ceramic enamel spandrel glass products are to be glazed against a uniform, opaque background. Search. 125" thick, so the air gap for a 1" IG with two panes of glass will be approximately 0. 2-hr-°F (low-e IG)-Edge of Glass (EOG) Typical value 0. 27 . What is the best R-value for windows and doors? Improved education and awareness of the cost of heating and cooling that escapes from poorly insulated components and glass panes have led to window and door U-Value.

Solar Heat Gain Coefficent is the fraction of incident solar radiation entering a home through the windows. R-Value is the inverse (R=1/U) of the U-Factor. U-VALUE The U-value is the measure of how much heat is transferred through the window. On top of that, you will also find a U-value to R-value chart for U-values ranging from U At Energlaze we specialise in providing glazing solutions to increase the comfort of your home and lower your heating bills. 760". A leader in tools for the glass industry. (5) UV Damage Weighted Transmittance (Tdw) is the weighted average for wavelengths 300 - In this section, we will explore the difference between two of the most significant glass performance measures; U-Value and R-Value. U-Factor Describes the resistance of the door glass to conducting heat and cold through the unit. 65 Solar Heat Gain Coefficient 0. It also notes that U-value has an inverse Find technical specifications, installation instructions, construction specifications (CSI), CAD/BIM files and parts manuals for all Marvin products. 6 2. 2-hr-°F (aluminum spacer)-Frame. A lower U-Value indicates better insulation properties and is particularly important in colder climates where thermal insulation is critical. Typical value 0. By filtering by Visible Light Transmission, Solar Heat Gain, Reflectance and U-Value you can find a product that meets your requirements for any given combination. U-Values range anywhere from 0. Indicative U values for windows with wood or PVC-U frames εn is the emissivity of the low E glass. National Processing Capabilities . This can improve Window and door energy Data resources. 29 BTU/ ft. The overall IGU U-factor can be determined using the EOG and COG values and will be affected by the IGU make-up, including spacer type, IGU gas fill type, coatings, overall thickness, etc. The lower the u-value the more restrictive the fenestration product is to heat transfer; reciprocal of r-value.

In cold climates, the best U-factor is anything at or lower than 0. Join as we dive deeper to understand the differences and why this is important for both commercial and residential properties. Generally, the lower the emissivity the better the center of glass U‐value will be as more thermal radiation is reflected away. Performance documents for altitude limits, NFRC ratings, center of glass, joining window load table, air infiltration, and more. Because Low-E glass improves (lowers) the IG unit U-Value, using Low-E glass will increase the unit’s interior glass surface temperature. 55 Visible Light 72% U-Value 0. 5 85 8 8 65 7 <1 5. U-value. Therefore, R-Value multiplied by U-Value always equals 1. It is strongly related to glass surface emissivity, gas type and gap The glazing on the glass has its own U-value. Using the above mentioned U-values, you can quickly measure how efficient your R-value is the reciprocal of U-value or U-factor (the Heat Transfer coefficient). Clear 6.

Look for a higher R-Value for a more energy efficient product. 35, not 0. This is more of an engineering term used to designate the thermal performance of a system as opposed to a homogeneous material. The ROCKWOOL U-value calculator is backed up by around 2,500 pre-determined calculations which show the overall performance of a wall assembly, or floor and roof build-ups featuring ROCKWOOL insulation solutions. The prescriptive path means the window product must meet a U-Factor value that’s ≤ 0. To achieve optimally efficient U-Values, Low-E (low-emissivity) glass or Low-E coating in combination with double-glazed units are appropriate. 2021 IECC Only: A maximum U-factor of 0.

To calculate the U-value of a glass unit, you need to consider three main factors: Thermal resistance of the glass panes (Rg): The thermal resistance of each glass pane depends on its thickness and thermal conductivity. 4 W/m2K. Hence: the lower the U-value the better (similarly, the higher the R-value the better). Production samples structurally tested and labeled in accordance with one or more of: AAMA/WDMA/ CSA 101/I. Generally, thicker glass panes have higher thermal resistance. (3. 2-hr-°F (thermal break) Frame U-Factor includes heat transfer through surfaces perpendicular . The following table gives centre pane U-values for the constructions and cavities shown. Heat loss is quantified by the thermal transmittance or U-value (U). F/Btu. United States R-values are given in Imperial units (ft2 ºF hr/Btu), but R-values can also be expressed in Metric units. Finally, there is U-value, known officially as thermal transmittance. It is NOT a measurement of the rest of the window, and does not reflect the thermal efficiency of the frame and other window components.
