When you need to buy anything for your home that costs more than a few dollars, you might turn to the internet to help you research products. The internet is a great tool and you can learn a lot! If you need replacement windows, you’ll probably want to figure out how to read the labels first in order to compare the windows once you go out to actually see them. It’s great to be informed because most homeowners haven’t had to replace windows before so they aren’t experts.
As you research replacement windows, you’ll come across terms you may have never heard of before, but they can be important when it comes time to make decisions. Terms like R-value and U-value will come up quite a bit and they matter when it comes to energy efficiency and quality in replacement windows. Let’s take a closer look at R-value to help you get started.
R-value is the unit of measurement that the window industry uses to describe thermal resistance on replacement windows. In simpler terms, the R-value tells you how well a window will insulate your Malibu, CA home. The higher the number, the better it is because it can slow heat flow through the window. You want a high R-value because it means less heat will transfer, either in or out, giving you better energy efficiency.
As you look into R-value, you may get confused by its counterpart, U-value. U-value is the inverse of R-value because it measures how well materials conduct heat. You want lower U-values as an indication of higher energy efficiency. It has a greater insulation and heat flow resistance with a low number.
When you look at window labels, you will see both of these values listed within the ratings and they are very important to pay attention to. The volume of information on those labels can be very overwhelming, but comparison shopping is easier when you understand R-value.
You will also want to watch or the Energy Star label because the certification system helps you identify energy efficient products that meet a certain level of requirements. There are going to be variations under the label and some will have higher R-values than others, but you know they at least meet the standards of Energy Star’s certification program. Watch for that label first and then go to the individual ratings.
There are plenty of other ratings you might want to know, such as visible transmittance, air leakage, and more. But when you work with the professionals at Concept Windows & Doors, we can help you with all of that. We don’t want you to go into an investment this large blind.
