When choosing new windows, homeowners should always consider several factors besides style and appeal. Energy efficiency is one aspect that you should pay attention to during the selection process. Over the years, it has been proven that you can enjoy a comfortable home while maintaining lower energy expenses if you install energy-efficient replacement windows.
Checking the solar heat gain coefficient (SHGC) and U-value are crucial to determining how energy-efficient a window is. To help you select the right window for your home, here’s an overview of SHGC and U-value.
What Is SHGC?
The SHGC measures how much solar radiation enters your home through the window glass. Generally, a lower SHGC rating means less heat is absorbed through the window. That is why you should consider windows with a lower SHGC rating if your area receives a lot of direct sunlight. These windows will prevent your spaces from heating up and your air conditioner from working too hard – thus lowering your energy costs.
According to window contractors, windows with a higher SHGC are advantageous if you live in a cold climate. A higher SHGC rating means more heat is allowed into your living spaces, making heating easier, especially during winter.
What Is U-Value?
U-value describes a window’s ability to act as insulation. It measures how quickly heat from hot air passes through the window glass. A lower U-value means better insulation for your home. Windows with a lower U-value do an excellent job at blocking off heat in summer and winter. You can rely on them to maintain year-round comfort.
It is critical to understand that there is no one-size-fits-all approach to selecting replacement windows. Besides your home aesthetic and layout, your local climate and the orientation of your windows are also important factors in your decision.
