One of the main reasons why people choose to install replacement windows is because they would like to ensure that their homes receive better insulation properties and decrease in heating or cooling loss. Older windows were designed to provide ventilation into the enclosed area, which would become stuffy and hot if no ventilation was present. However, other concerns such as the ability to keep the heat or cool air from dispersing or staying during different seasons were not really the focus of windows. In time, as people found that windows could play such roles, design after design took up what are called the R and U factors.
The R and U factors are basically technical terms that a person would need to know when on the search for windows. The U factor refers to the transfer of energy, which measures the ability of a window to transfer energy, such as heat or cool air, from the room to the outside, or vice versa. On the other hand, the R factor refers to a window's ability to contain energy.
Typically, people aim to find for replacement window ratings with the lowest U factor, and the highest R factor possible. Having the lowest U factor means that energy does easily transfer from one side of the window to the other, meaning less loss of heat or cool air. A high R factor means that the window is able to keep the heat from dispersing too easily. This combination makes a great way to save electric and conserving energy during hot or cold seasons when heaters or air-conditioners are continuously used throughout the day. However, if you live in a tropical country, these may not be as much of a concern, hence affect less of your R and U factors.
With replacement windows, people can make it possible to achieve a comfortable home at any season. Simply look for the right replacement window ratings and your house may feel different entirely.
