Windows are obviously a very important part of sunrooms!“Low e” is short for “low emissivity” or if you want to get even more accurate, “low thermal emissivity”. Reflectivity is inversely related to emissivity. All materials have a value for reflectivity and emissivity. For instance, a red brick has an emissivity of 0.9 and a reflectance of 0.1. Glass is naturally a high emissivity material with a low reflectance value (when viewed at a 90 degree angle). (more…)
