There are two types of sliding windows, horizontal and vertical. Sliding windows are usually made of vinyl or composite. The frame of the window itself can include a solid foam core that helps with insulation and reduces heat gain. When selecting a sliding window, you also have the choice between single hung and double hung. A double hung window allows for maximum ventilation, so on days that it is indeed lovely out, and you want airflow, these will allow for the best incoming breeze.

Something to consider when purchasing a new sliding window is how well it does with its energy rating. There are two values to look at, the R-value and the U-value. The R-value measure a unit's resistance to heat, and this number should be higher. The U-value represents the amount of heat material can transfer and should be a lower number. To do shopping for a new sliding window more relaxed look for an Energy Star logo, this will ensure you are getting an energy efficient unit.
