What is iWindow? iWindow is a custom-built, interior mounted, retrofit glass system for aluminum storefront, curtain wall, and window wall that delivers unprecedented thermal and sound-reduction performance at a fraction of the cost of full glass replacement.
What is the targeted fenestration system for iWindow? iWindow performs best and shows the quickest ROI when installed on older, single-glazed aluminum framed wall systems that display poor stand-alone thermal performance.
Is field assembly required? No. The iWindow panel will arrive at the site fully assembled, with the mounting tracks and screw covers finished to match and ready for installation.
What is a typical installation time? Since iWindow is shipped fully assembled, installation time on a typical curtain wall opening is as little as 20 minutes. As project conditions vary, installation times may vary as well.
What work needs to be done to the existing window prior to installing iWindow? Prior to installing the iWindow system, the existing system should examined for air and water infiltration and sealed as necessary. The existing glass should be cleaned and the condition should be inspected for loose paint or caulking, which should be removed and repaired.
Will condensation be a problem? The likelihood of condensation is very low, primarily due to the multiple insulating chambers. Condensation occurs when the interior surface temperature of the window assembly falls below the dew point of the adjacent air. The potential for interior condensation increases in buildings in colder climates, particularly if the interior is humidified during cold weather. As the iWindow can provide higher insulating value of typical older monolithic glazing, the indoor glass temperature will be significantly higher, thus lessening the potential for condensation. In the rare event that condensation does occur, iWindow is designed to distribute any moisture away.
Do I need to be concerned about thermal stress glass breakage? When iWindow is installed in an existing opening with a single 6mm lite of either clear or tinted glass, thermal stress breakage is not a concern. In cases where the existing exterior lite is other than described above, we highly recommend that you consult with your Serious Energy Sales representative prior to ordering to insure that a thermal stress analysis is performed.
Is Heat Strengthened and / or Fully Tempered glass available for iWindow? Yes, both are available as options for iWindow. While not required in most installations, it is advisable to consult local building code officials prior to ordering to be sure that your project is in full compliance.
Do I need to be concerned about the added weight on my curtain wall system? Since the iWindow system uses a unique vertical mounting track, when properly installed the majority of the weight of the iWindow is transferred to the vertical members of the existing system. The integrity of the existing system and its ability to support the added weight of iWindow should be analyzed by a structural engineer prior to installation.
My opening is larger than the maximum size for iWindow, is there some way to still use it? Two iWindow units can be used to span larger openings with the use of a structural mulling tube. Please consult your Serious Energy Sales Consultant for further details.
Which iWindow glass package should I chose for my project? Serious Energy offers both low and high solar gain glass packages for iWindow. Which package is used depends on the design intent of the project, however Serious Energy recommends that the low solar gain package be used on projects where the existing glazing is clear, and the high solar gain package be utilized on projects where the existing glazing is tinted. The concept of spectrally selective ‘tuning’ is also possible with iWindow, whereby the low solar gain package is used on the southern & western facades to reduce summertime solar gain, and the high solar gain package is used on the northern & eastern facades to take advantage of wintertime solar gain.
