Advantages of Triple Pane Glass for Commercial Windows
Whether beginning a new commercial construction project or replacing windows in an existing building, choosing the right type of glass is a critical part of the planning process. There is a great number of different types of glass available, with dual pane being the most common. However, triple-pane glass can provide a wealth of advantages for commercial buildings.
Door and Window Market outlines the three key advantages of triple pane windows in commercial construction:
1. U-Value Optimization
Energy efficiency is top of mind in many modern construction projects and triple-pane windows optimize U-values. Air circulation increases convection, which decreases thermal performance, by transferring heat. Triple-pane designs create two smaller air gaps, resulting in less convection and consequently better thermal performance. In addition, low-conductivity gases like krypton and argon/krypton blends tend to be more effective in smaller, more confined areas, resulting in optimum U-values.
2. Condensation Resistance
Condensation occurs when the inside temperature is higher than the outside temperature. In addition to being unsightly, over time the moisture from condensation can cause damage to window frames. Triple-pane windows have a higher condensation resistance than dual-pane windows, because of the additional layer of glass. According to Door and Window Market, condensation resistance on triple-pane windows can be boosted by using warm edge spacer systems.
3. Sound Attenuation
Triple pane windows make an enormous impact on acoustic comfort. As Door and Window Market explains:
Triple-pane windows allow window manufacturers to achieve improved (higher) STC ratings, by taking advantage of the science of decoupling. Materials of identical characteristics respond to sound waves in identical ways. So, by combining materials of dissimilar characteristics, sound waves of dissimilar wavelengths are generated. These offsetting wavelengths will “decouple” or cancel out one another, as opposed to those of similar wavelengths which build upon each other, creating amplification.
Triple-pane configurations allow for the use two different sized air cavities versus the same sized gaps, or two different glass thicknesses. Even two different glass materials, such as conventional versus laminated glass, can be used in triple-pane designs to decouple sound waves, thereby achieving even higher STC values. The result is less sound transmission from passing planes, trains, automobiles, neighborhood kids, lawnmowers and barking dogs.
For these reasons, triple-pane glass is an excellent choice for buildings in a noisy environment and a cold climate. Triple pane glass can provide the greatest reduction to heat loss and acoustic comfort, while also improving energy-efficiency.
