Installing energy efficient windows that improve several aspects of the environment you’re residing in is quite essential. Right from providing warmth, light and ventilation, the windows should enhance energy use and conservation. Reducing energy costs, especially if you’re on a tight budget is another factor that can be considered. If you’re initiating certain improvements, the purpose is to increase energy efficient strategies.
What is the U-factor of thermal resistant replacement windows?
Modern impact windows are equipped with technologies that achieve energy efficiency, which is higher than that of traditional windows installments. However, it can be quite confusing for homeowners to understand certain terminologies associated with impact resistant window replacement. Something as simple as thermal resistance of a material or the U-factor can leave average consumers clueless. There can be several reasons why windows should be replaced. Right from ageless cracks to air leakage, picking out windows with thermal resistance is always a factor to consider. However, analyzing the U-factor of thermal resistant hurricane replacement windows is a necessary step in proper window treatments.
Instead of feeling overwhelmed by terms like ‘Low e-glass’ or ‘argon gas’ you should embrace the efficiency and durability of window treatments. Thermal replacement windows are rated accordingly to their function, type and strength. Such a rating system which categorizes heat resistant windows has been introduced by National Fenestration Ratings Council in the form of the U-factor. The unit measures the magnitude of heat loss that occurs in a window that has been installed in a specified area. Thermal replacement windows are an affordable and appropriate choice to counter heat loss during the winter season and cooling loss during the summer months. With suitable ratings, clear comparisons can be formulated while making a sound purchase. To obtain the ‘Energy Star’ label which is an authorized green label such performance ratings like the U-factor have been introduced.
U Factor Ratings – Impact Window Types
- Single Pane Window- 1.0
- Single Pane with Storm Window- .6
- Double Pane with low E-glass – .4
- Triple Pane with low E-glass- .25
- Old Metal Casement Window- 1.3
Things to Note on U-Factor
It is essential to note that the U-factor of thermal resistant windows is measured on a scale from 0.10 to 1.20 (this is considered to have the least heat efficiency) which means that the lower the rating gets, the lesser heat is lost. Energy efficient windows carrying a low U-factor, account for cost effective measures in terms of heating costs year after year. Depending upon location, U-factor of windows can be analyzed. In order to obtain the Energy Star level, the U-factor will have to be a specific level depending upon the climate of the area. For example, in the Northern states, U-factor in the US is said to be 0.30 or lower that achieves Energy Star label while in the Southern corner, the U-factor can be higher. While selecting energy efficient windows, you will need to consider a major number of options. Right from design to distinct energy performance ratings, windows can be installed adequately. Some of these important performance ratings are studied below:
How are Performance Ratings Beneficial?
- Air Leakage
The U-factor ratings measure the amount or quantity of air that filters in through the window allowing consumers to utilize installations with selective ventilation. Fixed or awning style windows offer best ventilation within a typical range of .1-.3 that calculates air leakage rates.
- Solar Heat Gain Coefficient
It is the exact opposite of U-factor that measure heat loss while this parameter calculates the magnitude of heat gained during the summer months. Solar design strategies dictate a rating higher than 0.6 to maximize thermal heat gain during winters hence offering a U-factor of 0.35 or less for complete efficiency.
- Visible Transmittance
Another parameter often misjudged is visible transmittance which measures the amount of light that sheds inside. The higher the number the more photonic energy you can expect within your homes. U-factor gives a quantified measure of the magnitude since it calculates heat energy.
- Condensation Resistance
Another window rating that greatly affects your choice is condensation resistance which calculates the window’s ability to prevent any form of condensation from taking place. The higher the rating, the better it is for improved energy efficiency.
With a number of performance ratings being introduced the U-factor of thermal resistant replacement windows is one of the most important parameters. If you understand U-factor then you can avoid confusing sales pitches and interpret technological terms while making a purchase. The windows having U-factors between 1.3-2 and lower are better equipped at performing energy efficient tasks.
