With cold weather approaching, now is the time to consider replacement windows. The most important rating to consider when determining the ability of a window to keep warm air inside your home and cold air out is the U-Factor (NFRC Ratings Sample Label). The way to understand U-Factor ratings is to consider the following facts.
In 2008, in order for a window to be considered Energy Star Rated, the U-Factor had to be equal to or less than a .40. In 2009, tax credits on energy efficient windows were given if the window was equal to or less than .30 which was a huge change in the industry at the time. This trend shows a few things. For starters, it demonstrates that the lower the U-Factor the more energy efficient the window, particularly in the colder months. The other thing this shows is that there is a strong movement towards higher performance windows by regulators and experts.
The newest agenda on the discussion card is the next generation of windows is circulating around R-5 windows. R-Value is a method for measuring the insulating rating of any surface, more commonly walls and attics. R-5 windows are achieved with a U-Factor of .22 or lower.
Window manufacturers are able to achieve R-5 rated windows mainly with heavier, more costly triple pane units. Triple pane windows are not ideal in the Mid-Atlantic region. The costs far outweigh the efficiency gains and in some cases actually create a negative effect by blocking too much sunlight in the winter.
Fortunately, Home Visions Inc. has the perfect R-5 double pane window for the customer that is looking to outpace the trends. Through strong partnership with Vytex Windows based in Laurel, Md (Howard County) we are able to offer a state of the art window that is guaranteed to meet government standards for years to come at a price that is not much higher than our standard double hung packages (U-Factor of .26).
