The premium vinyl used in SimontonвЂ™s windows and doors is inherently and excellent insulator. When it comes to energy efficiency, how do vinyl windows compare with windows made from other materials, such as wood and aluminum?ДЄ. Helping keep the heat out and the cold in during summer.Helping keep the heat in and cold out during winter.The higher the R-Value the more energy efficient the window is. Improving the performance of the U- and R-values of your new windows and doors. Remember, the lower the U-Value the more energy efficient the window is.Insulating glass improves the quality of Simonton windows and doors by: How does insulating glass improve the quality of SimontonвЂ™s windows and doors?ДЄ. The higher the R-value, the better insulated are the walls and ceilings. The term does not translate well to windows and other fenestration products, so the industry prefers to use U-values. Because of its density, itвЂ™s used to replace air between the glass panes to reduce temperature transfer for better thermal efficiency. R-value is usually quoted when discussing things such as wall and ceiling insulation values. Low E (Emissivity) glass has a special surface coating that allows short-wave energy to pass through but reflects long-wave infrared energy, improving the U-Value.ДЄrgon Gas is an odorless, colorless, tasteless, non-toxic gas that is six times denser than air. What is Low E/Argon-filled glass, and how does it help improve energy efficiency?ДЄ. When shopping for windows or doors, look for higher R-values and lower U-values for the most energy-efficient products possible. The lower the U-value, the better the insulating quality. U-value is the amount of heat transferred through a material. R-Value Area Calculator Calculator to help work out the total R-Value of a wall with a window or other fitting within it. Great for working out rate of heat loss or gain. The higher the R-value, the better the resistance. R-Value calculator to work out the total R-Value of a set of materials, say in a wall, ceiling or floor. R-value is the resistance a material has to heat flow. What are R-values and U-values, and why does it matter?ДЄ. Just choose the ENERGY STAR glass package based on your regionвЂ™s climate zone. Simonton has taken the guesswork out of choosing energy-efficient glass packages that meet ENERGY STAR guidelines. In terms of window assemblies, R-value is less commonly used, because it refers to a specific material component of a window, i.e.

In other words, more energy efficient windows have lower U-values.

Which options do I select for my windows and doors to meet ENERGY STAR guidelines?ДЄ. For instance, you can determine a windowвЂ™s U-value with this equation: 1/R-value U-value. Only windows and doors that meet strict criteria set forth by the EPA are ENERGY STAR-qualified. An ENERGY STAR rating is your assurance that windows and doors will deliver effective thermal performance in your climate zone. How do I determine which windows and doors are energy-efficient?ДЄ. This is different than R-value that would be used to determine the energy efficiency of just the window pane, thus a window with a U-value of 1 is more energy efficient than an window with a U-value of 5.Q. U-values are used to determine the insulating efficiency of the window and all of its components. Keep in mind that this is the opposite for U-values. The two most common and recognizable energy ratings for windows and doors are U-value and Solar Heat Gain Coefficient (SHGC). Materials that are very inefficient are listed out with low R-values such as R-1, where more energy efficient materials are listed out at R-5. Materials with higher R-values provide better insulation and are able to resist heat more than something with a low R-Value. The United States government created regulations around energy efficient building materials and mandated that values be added to materials for more efficient use of natural resources. R-value is used to define the energy efficiency of a particular building material and originally was developed for measuring the thermal performance of insulation. Both of these terms, R-value and U-value, are commonplace terms in the remodeling and construction industry and are used to define how energy efficient a material is.
