When updating your windows, there are many things to consider, like the color, type and material. Of course, you also need to look at their overall energy efficiency and follow certain guidelines.
One critical aspect of a window’s energy efficiency is its capacity to properly maintain heat inside your home. This is measured by its solar heat gain. This article details what this is, how it affects your home and how it is measured.
Solar Heat Gain and Its Effects on Your Home
Solar heat gain is the ability of a material to block heat from the sun. While they do their job in bringing in natural light, it is imperative that your windows only allow a certain amount of energy from the sun to enter your home. Otherwise, you may experience a natural phenomenon known as the greenhouse effect.
This process can happen inside your home, especially if your current windows have a much higher solar heat gain. This can be problematic during the warmer months, which can affect your energy bill. An energy-efficient window can help curb this problem, and Renewal by Andersen® of Houston has the replacement products that take into account the solar heat gain coefficient (SHGC).
Measuring Solar Heat Gain
A window’s SHGC is expressed in terms of a ratio. A rating of 1 means the maximum amount of solar heat gain that can come through a window; a rating of 0 means the least amount. The lower the SHGC, the better a product is at blocking unwanted heat gain. However, it is important to take note that these ratings vary in every climate. In Houston, for example, the SHGC of a window should be not more than 0.27.
