Customer can choose a surface to apply a Low-E coating
We recommend Low-E coatings be put on either Surface 2 or Surface 3 due to the fragile state of the coating. Applying the Low-E coating to an interior surface will protect it and make it less susceptible to scratches and wear.
- Surface 1: Most exterior surface. It is the surface that has direct contact with the outside.
- Surface 2: Outside facing interior. Commonly used for Low-E coating for southern facing windows with direct sunlight in warmer climates that are trying to reduce the amount of heat transferred into your structure.
- Surface 3: Inside facing interior. Commonly used for Low-E coating for windows with indirect sunlight that are trying to reduce the amount of heat transferred out of your structure.
- Surface 4: Most Interior surface. The exterior surface that faces the inside
Spacer– Anodized aluminum separator that is vented and filled with desiccant, a moisture absorbing material to avoid condensation on interior surfaces
The space between the glass can be filled with air or you can enhance your Tower Insulated Glass unit even father by adding a gas to it.
- Argon– Reduces transfer of heat, reducing energy costs
- Krypton– Similar to Argon, only denser which makes it a better insulator
- SF6– reduces the amount of sound that travels through the unit
