A Guide to Choosing the Right Glass for Your Windows

Choosing the right glass for your exterior windows can have a significant impact on your home's energy efficiency and comfort level. Two key factors to consider when selecting glass for your windows are U-value and SHGC (solar heat gain coefficient). Here's a guide to help you understand these factors and choose the right glass for your needs:

  1. Understand U-Value. U-value measures how much heat is transferred through the window from inside to outside or vice versa. A lower U-value indicates that the window provides better insulation and reduces heat loss in winter. If you live in a colder climate, it's essential to choose windows with a lower U-value to keep your home warm and comfortable.

  2. Understand SHGC. SHGC measures how much solar radiation passes through the window and into your home. A higher SHGC means that more solar heat enters your home, which can be beneficial during the winter but could lead to overheating in the summer. If you live in a warmer climate, it's essential to choose windows with a lower SHGC to prevent excessive heat gain and keep your home cool.

  3. Consider Climate and Orientation. Your home's orientation and climate will also play a crucial role in determining the right glass for your windows. For instance, if you live in a warm climate with a lot of sunshine, you might choose low-E glass with a low SHGC to reduce heat gain. On the other hand, if you live in a cold climate, you might choose  windows with a low U-value to increase insulation.

  4. Understand Sound Transmission Class (STC). Sound Transmission Class (STC) is a rating system that measures the ability of a material or structure to block sound. A higher STC rating indicates that the material or structure is more effective at reducing sound transmission. When selecting glass for your soundproof windows, look for glass with a high STC rating to ensure effective noise reduction.

  5. Consider Laminated Glass.  Laminated glass is a popular choice for soundproof windows because it consists of two or more layers of glass with a layer of polyvinyl butyral (PVB) between them. This interlayer helps to absorb sound and reduce noise transmission. Laminated glass is also more durable and resistant to breakage than regular glass, making it a safer option for your home.
