Guardian Industries has published a new case study on high performance coated glass that demonstrates that not all low-Es are created equal.

Guardian’s SunGuard SuperNeutral 68 helped the owners of a medical plaza solve a glass problem by using a new coated glass product that exceeded their goals in terms of quality, cost and comfort.

The study, “Just what the doctor ordered: New low-E glass reduces heat, increases comfort of occupants and patients,” is available at

In 2005, construction began on a medical plaza outside of Nashville. Plans called for two identical 45,000-square-foot, three-story commercial buildings, to be built in two phases. After building one was completed, the troubles began. Staff and patients experienced discomfort due to heat gain in the building and energy costs were also higher than expected. Understandably, in 2007, the project architects looked for a better performing glass for phase two of the project.

“Just what the doctor ordered,” explains the difference between the two low-Es that were specified for the different project phases, the performance of each, and ultimately, the advantages and cost savings that were recognized on the phase two building using the higher performing coated glass. Guardian’s SuperNeutral 68 was used to replace two elevations in the first building and for all the glass in the second building. An analysis showed a 43% reduction in overall heat load due to the new coated glass.
