Types of Cardinal Low-E Glass

While shopping for new windows, you’ll find many materials, finishes, and types of glass to make your project complete. While window frames are fortified with new materials, finishes, and coatings, glass can also be given extra benefits such as insulation and strengthening coatings.  Buyers should learn what type of glass they are getting before committing to the purchase since this decision affects your home's look and energy-efficiency.

Cardinal Glass is one of the biggest manufacturers of window glass in the United States. In fact, most window manufacturers get their glass from this corporation. This guide will describe each type of glass so that you can make the best decision for your next upgrade. For reference, here are a couple of terms to know throughout this article:

  • U-Factor: This value measures how well a window insulates. In windows, it typically ranges between 0.20 to 1.20. On this scale, the lower the number, the better the insulation.
  • SHGC (Solar Heat Gain Coefficient): This value measures how much solar heat comes through the glass. This scale typically ranges between 0 and 1. A low SHGC means that less heat comes through the window.
