Glazed and Tinted Windows: What You Need to Know
Understanding Glazed and Tinted Windows
Glazed or double glazed windows are energy efficient windows consisting of two panes of glass instead of just one. The panes have a seal between them that creates an additional layer of insulation. The space between the panes may be filled with air or gas. The added insulation keeps heat in during winter and out during summer, which cuts energy transfer by half. Glazed windows also reduce noise.
Glazed windows are also available in triple-pane styles called triple glazed windows. Instead of two panes of glass, triple glazed windows have three. The space between the panes may be filled with gas, such as argon, or air. These windows are quieter and even more energy efficient than double glazed. They are common in areas with severe weather.
Tint is a special type of material that changes the color of glass. The most common colors for windows are gray and bronze, but blue and green are also options. Tinted glass minimizes the penetration of light and heat through the windows. In homes or buildings that have no shade, tinted windows can help keep the temperature inside comfortable and reduce glare.
Tinted windows can have a negative effect on indoor plants. When tinted windows transmit less than 70 percent of visible light, plants grow more slowly or they can die.
Gray and bronze offer the most protection, while blue and green allow more light and only slightly reduce heat transfer. Black tint absorbs more light than heat, so it should be avoided in hot climates.
