All parts of our home are important, each with its own set of functions, which can include providing our home with protection, enhancing its curb appeal, and improving comfort. Among these components are windows, which allow natural light into our homes. They also provide protection against the elements and maintain comfortable temperatures inside the house.
There are several things you need to know about your windows to better understand how they function.
Terms You Need to Know
When buying replacement windows in Kansas and in surrounding areas, the following National Fenestration Rating Council (NFRC) terms are used to measure performance:
- U-factor and R-value
U-factor measures how well a window can prevent heat from escaping a room. R-value, on the other hand, measures the resistance to heat loss. Windows with a lower U-factor are better at storing heat inside your home.
- Solar heat gain coefficient (SHGC)
The SHGC indicates how much solar heat is blocked by your window. The lower your window’s SHGC, the better it can block heat gain.
- Glass visible transmittance
Visible transmittance measures the amount of light passing through your window.
Factors Affecting Window Performance
Below are various factors that can affect a window’s performance:
- Number of panes
Single-, double-, or triple-pane windows bring different levels of energy efficiency. Windows with two or more glass panes are usually filled with low conductive gas used to slow down heat transfer.
- Frame materials
Some frame materials like vinyl, fiberglass, and wood are better conductors of heat than others. Windows whose frames are less conductive can reflect heat away during summer and keep heat inside the room during winter.
- Gas between panes
The space between glass panes is filled with gases like argon or krypton to lessen both conductive and convective heat transfer.
Each window style or design has a purpose—whether to add space to a room, provide more light, or help save energy. A truly superior window can do all, if not more.
Choose the Right Window
Familiarizing yourself with different window terms can be helpful for your window replacement project. Also knowing the factors that affect window performance can also help you find windows that will suit your home’s particular needs as well as your personal taste.
