Super-Insulating Glazing Advantages of Suspended Film
Combining both film and glass-based low-E coatings creates a lightweight, multi-cavity insulating glass unit that reflects heat and harmful UV radiation while maximizing light transmission, and provides superior insulation performance ranging from R-6 to R-20 center of glass.

Triple Pane vs Suspended Film
The transition from single pane glass to dual pane (with a single-cavity) provided an improvement in thermal performance. The introduction of multi-chamber glass packages – created by two or three suspended, wavelength-selective thin film technology – allow for significantly improved energy savings performance, superior durability and longevity, and installation advantages over triple-pane glazing solutions, depending on location, building type, and other factors.
Extra Weight of Triple-Pane Glass Compromises Functionality, Durability and Ease-of-Installation
Triple-pane glass units can be significantly heavier than standard insulating glass. The heavier glass requires stronger framing systems which can increase the overall cost of any building project. The extra weight can also impose strict size constraints, and may affect how much glass is used in the design of a building – impacting the overall aesthetics of a structure. General functionality of triple-pane windows is also affected by their weight. Additional stress is placed on all operable mechanisms in the window and the window hardware, wearing them out quicker.
Disadvantages of Triple-Pane Glazing:
- Potentially higher project costs (more labor, sturdier frames, stronger building design)
- More weight (heavier) than standard insulating glass
