Last week we looked at the degree day, a measure that describes temperature change from day to day. It is a concept useful in window energy efficiency ratings and standard setting. And as we all know in the window manufacturing industry, window energy efficiency, whether we’re talking aluminum windows, storm windows, patio doors, or storm doors, is one of the most important things to consider. The indoor climate depends on a quality energy efficient window block the external heat or cold that can swamp a house with high utility bills and an uncomfortable atmosphere. Today, moving along with our rigorous study of industry terminology, we’re going to look at the term, desiccant. This terminology describes an ultra porous crystalline substance that is often used to absorb moisture from inside of a sealed or space, such as insulating glass. That’s one for the books! While it may be a very obscure term, it might come in handy one day, so hang on to it. This week we are also going to look at the term dew point. This term has reaches far beyond the world of window manufacturing and the replacement window niche. Dew point is the temperature at which water that is suspended in the air will condense. Dew point changes depending on the current amount of humidity and the atmospheric pressure. Dew (the condensed water vapor) often appears on grass, windows, doors, and other solid objects outside. If you are wondering why we chose to look at dew point here on our Croft LLC. window manufacturing blog, wonder no more. A little later we are going to get even deeper into the scientific, so if that is your cup of joe, then be sure to read on, you’re not going to want to miss it. For some extra info, feel free to look over some of our previous material and dip a toe or two into the ocean of window manufacturing knowledge at your disposal.
