Understanding the Components of a Replacement Window Label

Understanding the Components of a Replacement Window Label

Congratulations on getting your new replacement window! But how well do you understand all the information contained on a replacement window label?

Congratulations on getting your new replacement window! However, there’s still more to learn, once the window is installed. For instance, how well do you understand all the information contained on a replacement window label? These symbols and ratings can be confusing and almost impossible for the average homeowner to tell apart. Luckily, we have put together this guide to help you understand everything you’ll see on the label for your beautiful new replacement window from Capital Remodeling.

Replacement Window Description

One of the first parts of the label that you’ll see is the replacement window description. This element is merely a description of what type of window it is. Look for the following pieces of information, such as:

  • Who the manufacturer is,
  • What the window frame is made of,
  • The glazing used in the window,
  • Which gas in-fill it uses, if applicable,
  • The low-E coating, if there is one,
  • And lastly, how the window operates (sliding, double-hung, etc.)

The U-Factor

Next, you should see what is called the U-Factor. It should fall in a range somewhere between 0.02 and 1.20. What do these numbers mean? They represent a measurement of your window insulation. You’ll know your replacement window is doing an excellent job of preventing heat loss if the U-Factor is relatively low.

Solar Heat Gain Coefficient

The next part of a replacement window label displays the solar heat gain coefficient (SHGC). You’ll see the SHGC on the right-hand side of the U-Factor. The range for this measurement is between 0 and 1. SHGC determines how well your window performs, especially in regards to sunlight exposure that causes what is known as radiant heat gain.

Visible Transmittance

Visible transmittance (VT) falls under the category called Additional Performance Ratings. Again, this range is from 0 to 1. It measures how much light will come in through the window. The closer it is the 0, the less light it will allow in. You need to balance SHGC and VT to ensure you can reduce solar heat gain while not spoiling your view.

Rating for Air Leakage

Most manufacturers will also include a score for air leakage. Any cracks in the window itself will allow more hot or cold air to pass through, so it’s important to find and fix any leaks as soon as possible.

Ability to Resist Condensation

If you inspect your replacement window label closely enough, you’ll see how well your new window can prevent the collection of condensation, based on a rating scale from 0 to 100. Condensation might not harm the window itself, but it can affect the windowsill and infiltrate the wall where the window is.
