Clear Low E Glass. Clear glass works equally well from your entry door to your patio door. The most common type of window used is clear glass.
Passive low-e coatings and solar control low-e coatings. The term Low-E is short for low emissivity It is specifically built to reflect heat from getting into your home while still allowing the light to enter. In a Chicago study clear storm windows saved about 13 percent of heating energy and low-e storm windows saved about 21 percent.
To reduce the emissivity of glass low-e coatings have been developed to minimize the amount of ultraviolet and infrared light that can pass through glass without compromising the amount of visible light that is transmitted.
These coatings offer a reflective barrier against ultraviolet and infrared light both of which can pass right through a normal untreated window. 14 6mm Vitro Solarban 60 on Starphire Low-E 2 or 3. What does it do. Instead it absorbs tons of heat energy from the sun and keeps it inside your home which is.
