What Are the Differences Between R-Value and U-Value?
By Windows Plus
When you’re in the market for replacement windows or glass patio doors, your installation team will provide a myriad of options. Each product and material used will have an energy code based on its efficiency. If you’re unfamiliar with these values, here’s some helpful information to review.
A Guide to Understanding the Difference Between R-Value & U-Value
What Is R-Value?
R-value helps consumers gauge how well various construction materials insulate and control the transmission of hot and cold air. When a product boasts a high R-value, it’s considered energy efficient, and in turn, embracing the material can successfully lower your utility bills month over month. The rating measures the overall resistance to heat transfer of each particular material within a replacement window. Thus, investing in double- or triple-pane glass and durable window frames can also contribute to R-value ratings.
What Is U-Value?
U-value, also commonly referred to as U-factor, is used specifically to rate windows and doors. Instead of measuring resistance to heat transfer, this value measures the rate of heat transfer. Thus, the lower the rating, the better the product performs in terms of energy efficiency.
How Do You Choose Your Replacement Windows?
When planning for window installation, lean toward products with a low U-value. In addition, look for materials with high R-values that will help insulate. Beyond the actual glass panes, choosing the right caulking, frames, and insulation surrounding windows and doors can help boost overall efficiency. According to the Department of Energy, property owners in the north-central region of the country, including Ohio and Kentucky, should aim for windows with a U-value of 0.32 or less.
