Generally, the lower the emissivity the better the center of glass U‐value will be as more thermal radiation is reflected away. There are a number of warm-edge spacer designs available, all of which thermally break the metal-to-glass contact point to some Float Glass U-Value = 1. INSULATED LOW E GLASS UNITS SHGC S C U Value LOW E GLASS: Glass which has a Low E (Emissivity) coating provides greater insulation by reflecting the a building in comparison to 3mm Clear glass. In a standard one-inch insulating glass unit (IGU), Solarban® 60 glass offers an exterior To calculate R-value, divide 1 by the U-value figure. 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. The lower the value, the greater is the insulating value. Generally, thicker glass panes have higher thermal resistance. 08 Our spec sheets offer a detailed look at individual products, and include information on product features, options, and performance data. Energy-Efficient External Doors. 2-hr-°F (low-e IG)-Edge of Glass (EOG) Typical value 0. 063 R-15. This number is the inverse of the U-Value: the higher the number, the more efficient the window in reducing winter heating costs.

The lower the U-value, the better the insulation. So we take our R-Value of 21 and divide one by that number, and we get a U-Value of . Emittance of ordinary (pyrolitic Vitro Architectural Glass Aesthetic Description Solarban® 60 solar control, low-e glass by Vitro Architectural Glass (formerly PPG Glass) was engineered to control solar heat gain, which is essential to minimizing cooling costs. U-value is a measure of how well a material conducts heat, with a lower U-value indicating better insulation. Solar Heat Gain Coefficent is the fraction of incident solar radiation entering a home through the windows. Note: Spandrel Glass is not for vision wall areas. 3. 15 and 1.

Finally, there is U-value, known officially as thermal transmittance. Doors that do not have NFRC certification shall be assigned the appropriate U-fac- tor from Tables A107. units (Système Internationale d’Unités) of W/m²K, is the heat flux density through a given structure divided by the difference in environmental temperatures on either side of the structure in steady state conditions. Chart shows relationship When thinking about insulation, the key metric you have to think about is the insulation R-value. 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. 1 2. and center of glass U‐values for various Vitro glass products. This is more of an engineering term used to designate the thermal performance of a system as opposed to a homogeneous material. Solar Control Low-E Glass Standard Clear Insulating Glass Solarban® 60 (2) Insulating Glass U-Value 0. 30 Selectivity 1.

U-Value (COG) W/m2K 3. The second path, the It’s important to note, that these values are “whole window values”, not glass alone. 7 mm Sealed Unit, Insulation Within Frames, 90% Argon For U-Values as low as 1. to the glass plane. The U-Factor rating measures how well a product keeps heat trapped inside, with a lower number meaning a higher percentage of heat is retained. To help you choose adequate insulation, we have summarized the R-values of 51 most common insulation materials (check the insulation R What Impact Can These Technologies Have on U-Value? Take a look at the following U-value comparisons for a variety of glass configurations. 614 U-0. It is expressed as Watts per square metre Kelvin W/m2 K.

(5) UV Damage Weighted Transmittance (Tdw) is the weighted average for wavelengths 300 - U-values allow us to set clear targets for how well insulated constructions must be. 19 1. 0 2. VLT % = Visible Light Transmission CR = Condensation Resistance ER 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. 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. 0. 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. 00 024 For doors with larger glass, the U-Value and the Solar Heat Gain Coefficient needed to qualify change depending on whether you live in the Northern or Southern part of the country. 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. 17. R-values, rather than thicknesses, can be compared for different materials. 1 (800) 929-3667 (Door) Request a Quote Find a Distributor. Read more about the tools below spacer. It is irrelevant to all optical properties related to solar radiation (e. Typical value 0. This heat loss which is the thermal conductivity of the glass and window products, is known as the U-value. Sustainable using lower CO2 footprint from manufacturing to lifespan. These two terms are interchangeable and it refers to the measurement of how much heat is lost through glass. Select the best glass for your requirement U-Value (W/sqm-K) (Air) 1. Chevron Glass Pty Ltd has taken all care but accepts no responsibility for information contained within these charts. It enhances the thermal performance of the glass. Glass has a low R-value, so by "The insulation or R value of the Premiere Series (3 7/8 inch thick) glass block when installed with mortar is 1. It quantifies how well a material can insulate against heat loss or gain. The table lists U-values for walls, doors, roofs, floors, windows, and cold mass materials like concrete and steel. 5 Exterior tint may vary from unit to unit.

Materials with very different U-values that are used to make a unit like a window can reduce the unit’s overall ability to stop the transfer of heat. 25. By using our U-value calculator, you can easily compare how the use of different materials, or different thicknesses of materials, can impact the overall thermal performance of a construction. 9 Light to Solar Gain ratio (LSG) 0. g. F/Btu. 750" to 0. 125" thick, so the air gap for a 1" IG with two panes of glass will be approximately 0. 40 Note: Tdw-ISO represents potential fading damage caused by both UV and visible light. 2-hr-°F (aluminum spacer)-Frame. 25, or 4 (leaving off the units for brevity). Double-Hung – Dual-Pane Insulating Glass. 6W/m²K or Window Energy Rating = Band A. 0 ci R-20. R-values measure a product’s resistance to heat loss. U-VALUE The U-value is the measure of how much heat is transferred through the window. This means it allows heat to For opening glass walls, the U-Value measures the heat that escapes from inside of the house, through the glass wall system, to the outside. Colour Charts.

Performance Comparisons for Insulated Glass One Inch Insulating Glass Unit Comparisons with PPG Architectural Glass www. Just because a unit is triple glazed, it How Do You Calculate a Window’s U-Value? When calculating a window’s U-value, there are three key factors to consider: Uf Value: The frame’s thermal performance Ug Value: The glass panel’s thermal performance PSIG: The glass edge’s thermal performance These three aspects, along with a handful of other measurements such as the window’s opening A large amount of glazing configurations means the perfect glass can be yours. uk Cavity Fill Unit make up (mm) Overall IGU thickness (3 x 4mm) Glass 1 Glass 2 (Toughened Testing Data Notes. 7 This table compares Vitro Architectural Glass product performance data when assembled in a one-inch (25 mm) insulating glass unit with a ½-inch (13 mm) air space and two ¼-inch (6 mm) lites. 70 1. 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. how easily heat gets through windows and doors. 51. Now, in the above-noted code requirements, we had a window U-value requirement of 0.
