Low-e glass is a vital component of energy efficient windows. It has a surface coating that operates as follows:
- It allows short wavelength heat from the winter sun to enter your home through the glazing.
- This solar energy works with your domestic heating system to warm up your room, which then gives off long wavelength heat radiation.
- A large proportion of that long wave heat would vanish back out through windows made of ordinary glass. However, the Low-e coating reflects that heat back into your room, i.e. the coating traps the heat in your home.
As a consequence, you will feel much warmer during the winter, and your pocket will feel the benefit of reduced heating costs.
