3. Enhanced triple-pane glass with HeatLock® technology (three Low-E coatings)
Enhanced triple-pane glass options with HeatLock® technology allow for three panes to be coated with a combination of two of our “soft” coatings — Low-E4, SmartSun, Passive Sun, and Sun — and our “hard” coating of HeatLock technology. HeatLock technology helps keep heat from escaping the home. When it’s combined with the right “soft” coatings, it can provide a glass option that’s suited to various climate types. Here are three options to be aware of:
- Low-E4 Enhanced Triple-Pane Glass with HeatLock Technology is ideal for homes where energy usage is split more evenly between heating and air conditioning and where there’s an intermediate amount of solar heat.
- Low-E4 SmartSun Enhanced Triple-Pane Glass with HeatLock Technology provides high thermal performance without too much solar heat gain, so it’s ideal in a home with lots of direct sun exposure. It’s typically used in southern climates.
- Low-E4 PassiveSun Enhanced Triple-Pane Glass with HeatLock Technology allows the sun to help heat the home, so it’s best used in a home that’s designed to handle a higher solar heat load. It’s typically used in northern climates.
