Yes, Low E glass (low emissivity glass) is specifically designed to help keep heat inside your home.
How Low E Glass Works
Low E glass has a microscopically thin coating on its surface. This coating is transparent but works by significantly reducing the amount of heat that can pass through the glass.
According to the provided reference: "Glass with a low E coating therefore keeps your home warmer by reflecting a higher proportion of the heat back into your home, and can keep you cooler by reflecting solar thermal energy from outside."
This reflection of heat back indoors is the primary mechanism by which Low E glass helps maintain warmth during colder weather. It acts like a barrier, preventing radiant heat (the kind you feel from a warm object) from easily escaping through the windows.
Benefits of Low E Glass for Heat Retention
- Keeps Interiors Warmer: By reflecting indoor heat back into the room, Low E glass helps maintain a more consistent and comfortable temperature.
- Reduces Heat Loss: It significantly reduces the amount of heat that is lost through windows compared to standard glass.
- Potential Energy Savings: Reducing heat loss means your heating system doesn't have to work as hard, which can lead to lower energy bills.
In summary, the special coating on Low E glass makes it highly effective at reflecting thermal energy, including the heat generated inside your home, thereby helping to keep it in.
